    IMPROVED DESIGN FOR HYDRAULIC VALVE AND HYDRAULIC VALVE TESTING RIGIMPROVED DESIGN FOR HYDRAULIC VALVEAND HYDRAULIC VALVE TESTING RIG: DESIGN AND PRODUCT DEVELOPMENT2014Självständigt arbete på avancerad nivå (magisterexamen), 40 poäng / 60 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The hydraulic testing rig is a machine that is used to test the hydraulic valves.The present testing rigs are used according to only some particular specification, but in ourproject we have developed a process and implemented the idea for building a UniversalHydraulic Testing Rig which can be able to test any kind of valves with simple adjustments.The hydraulic valves are mainly designed to carry out the flow of the hydraulic fluid with thedesired pressures. But it is observed that there are many pressure losses in the flow whichleads to the unreached flow pressures as expected. In a pre-project to this work a patentedhydraulic valve designed to improve the flow pressure of the hydraulic fluid. The main targetof the design of the valve is to decrease pressure losses and give maximum output from theother end of the valve. The Hydraulic Testing Rig is designed with the help of design softwareand flow simulation process helps to know about the pressure flow from inlet to outlet ofthe valve. After the testing of the design, the valve is tested on the new universal hydraulictest rig developed in this project. With the future use of the hydraulic valve test rig, thesimilarities and variations are observed from both the simulations done and test results canbe compared to optimize the valve design further. With the combination of hydraulic test rigand redesign hydraulic valve we will provide and experimental test rig possibility to bringthe better and maximum design that could be attained reducing the energy losses in hydraulicvalve designs.

    DEFINE BONE QUALITY: FROM TAPPINGTORQUE TO BONE QUALITY2017Studentuppsats (Examensarbete)
    Abstract [en]

    The tapping torque using in this thesis is used to test the quality of the jaw bone.Testing the quality of jaw bone is the first step of placing the implant. However,several existing methods for various reasons are not the best ways to measure thequality of bone quality. In this project, a solution explored in this pilot study wasbased on the fact that bone quality can be assessed from cutting resistance whentapping or threading in bone [Johansson P, Strid K-G. 1994], and the experimentwhich tapping into testing material has been done by Carlsson TL Medical AB.Authors’ duty is to analysis the data what we get from industrial supervisor tosummarize a formula to present the thickness of bone and createa scale connecting the tapping torque and material quality. Then compare thetapping torque of the known-quality material with the tapping torque of bone,quality of bone can be known. The study about measurement of bone thickness andscale connecting the cutting force with material quality describe the benefit thatdental implant surgery will more accurate than surgeon’s feeling and otherexpensive equipment according to the torque which is measured in pre-tappingprocess

    Integration of the computer-based design analysis activity in the engineering design process – A literature survey2014Ingår i: Tools and methods of competitive engineering: proceedings of the tenth International Symposium on Tools and Methods of Competitive Engineering - TMCE 2014, May 19-23, Budapest, Hungary, Vol. 2 / [ed] Imre Horváth & Zoltán Rusák, Delft: Delft University of Technology , 2014, s. 1181-1194Konferensbidrag (Refereegranskat)
    Abstract [en]

    Computer-based design analysis is nowadays a common activity in most development projects. Used for design evaluation, verification, validation, or as a support for design exploration, it fulfils an important support function for the engineering designer, thus making it essential to have an operationally efficient and effective integration between both the engineering design and design analysis activities in the overall development project. In this area, most works are focusing on software (mainly CAD/CAE) integration, but not on the integration between computer-based design analysis and engineering design at the process level or on the collaboration between the engineering designer and the design analyst. This paper presents a review of the literature on that specific topic, namely the integration of the computer-based design analysis activity in the engineering design process. Different research topics are identified and elaborated upon: integration in general process models; recommendations for the different analysis steps; analysis early in the engineering design process; integration of design analysis in the engineering designer's work; alternative usages of design analysis in the engineering design process; and others, such as recommending guidelines instead of process models, quality assurance aspects, education, and implementation issues. Some neglected aspects were also identified. Among others, there is a lack of research into the so-called technology development (development of design analysis procedures and guidelines), and a need for emphasis on uncertainties, both coupled with the design analysis activity.

    Development of a computer-aided fixture design system for lightweight grippers in the automotive industry2016Ingår i: International Journal of Design Engineering, ISSN 1751-5874, Vol. 6, nr 3, s. 237-261Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The need for dedicated fixtures for flexible manufacturing systems is increasing, as dedicated fixtures are lighter, more compact and, more accurate than flexible fixtures. The main challenges are that parts and processes are more and more complex, which requires designing novel or complex dedicated fixtures, and that, for one given flexible fixture to be replaced, several variants of such dedicated fixtures must be designed to hold a variety of individual parts, without imposing increased costs and delays. The systematic fixture design method and computer-aided design fixture system (CAFDS) developed and applied for the presented industrial case—novel design of lightweight (carbon fibre composite) robot grippers—is a possible approach to address these issues.

    Simulation of Removal Functions for Abrasive Grinding Tool: Numerical Simulation Of Tool Influence Function2016Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    A relatively large set of complex data can be described using a simple mathematical Prestonequation. However the parameter choices are an essential facet that determines the efficiencyof grinding. The depth and volume of removal contributes to a significant part of the grindingoperation that accounts for the manufacturing time. These interacting factors in the equationare studied to create, infer and compare the performance of three sets of grinding tools: padtool, brush tool and radial tool. The tools are generated using MATLAB and is provided as aninput for tool path generation. The geometry profiled by the tool influence function is generatedusing Preston equation and the analysis from the simulation shows that the pad tool can bepreferred in instances where maximum removal is required. The comparison amongst the toolswas made keeping the parameters (pressure and relative velocity) constant in the equation forthe different tools.

    Avgasreducering: Att leda bort avgaserna från dieselvärmaren vid besiktning.2017Självständigt arbete på grundnivå (högskoleexamen), 5 poäng / 7,5 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Vi fick som uppdrag av Besikta i Halmstad att ta fram en lösning på deras avgasproblem med parkeringsvärmare. Samtidigt som besiktningen av fordonet pågår kommer det ut giftiga avgaser från parkeringsvärmaren. Trots att det inte är någon stor mängd avgaser gör det att det blir jobbigt och obehagligt för besiktaren som under vissa sekvenser av besiktningen befinner sig under fordonet. Därav blev vårt uppdrag att ta fram ett lösningsförslag till det här problemet.

    Början av rapporten handlar om vilka krav och önskemål som finns för förslagen som togs fram och hur dessa styr lösningarnas utformning. När kraven samt önskemålen är vägda mot förslagen gick vi vidare med det bästa förslaget och gjorde lämpliga komponentval utefter önskemålen. Sedan skapades en 3D-modell av lösningsförslaget som vi kommit fram till.

    Produktutveckling: Koncept för ett modulanpassat glasräcke2017Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Projektgruppen har fått i uppdrag att ta fram ett produktutvecklingskoncept utifrån en befintlig produkt ur ErgoSafe AB:s sortiment. Det finns ett stort intresse för höj- och sänkbara glasräcken där krog- och restaurangbranschen dominerar. Uteserveringar försedda med ClickitUp är inte lika utsatta vid sämre väderförhållanden, vilket ger möjlighet till längre och fler besök. ErgoSafe har identifierat en betydande anledning till varför försäljningen inte har gått som befarat, som beror på att flertalet kommuner förbjuder ingrepp i markbeläggningen. Examensarbetet kommer att bistå ErgoSafe i deras arbete för att förenkla tillväxten i försäljningen genom att ta fram en modulanpassad variant som inte kräver markingrepp.

    Konstruktion av överkåpa till bergvärmepump2012Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Detta examensarbete är utfört i samarbete med Enertech AB. Det är ett konstruktionsprojekt med mål att utveckla en överkåpa med justerbar höjd. Överkåpan ska passa på tre olika värmepumpar EcoHeat V3, EcoHeat 300 and EcoEl V3.0.

    Vi har valt att följa Fredy Olssons metoder Principkonstruktion och Primärkonstruktion. Detta är metoder vi tillämpat tidigare och de passar bra in på detta projekt. För att få en lämplig design så har vi även tillämpat många metoder enligt SVID.

    Det inledande arbete har bestått utav en produktdefinition, en konkurrentsanalys och designverktyg som till exempel Moodboard och Persona. Det fortsatta arbetet bestod utav Idéskisser och utveckling samt sållning i flera omgångar. Ett grovt första utkast ritades i Catia V5. Detta utkast utvärderades samt bearbetades och ledde slutligen till en fungerande prototyp och en komplett konstruktion utav en överkåpa.

    Kriterieframtagningsformulär för lyfthjälpmedel inom bilindustrin2008Rapport (Övrigt vetenskapligt)
    Abstract [en]

    This technical report is part of the work that is performed under a MERA project, L-FAM II. Between 2006 and 2008 this was a part of a research project between Volvo AB, VINNOVA, Flex Prop AB, Halmstad University and Lund University. L-FAM II was the name of the project and it was to help the industry to facilitate flexible lifting aids for their chassis-building. Criterion is an important part in this project since some of those controls with the accuracy of the finished product will receive. This accuracy is reflected immediately when the product goes into production where it must secure the geometry of products for the welding of body components and cabins.

    In this project, carbon fiber materials have been an important part. The advantage of carbon fiber is its low weight in relation to its stiffness. The cost of the material is not in its favor.

    The lifting devices that means here are constructed based on these criteria and are already in production. The system has been named NBT2 and is a patented solution in which ABB is the owner of the patent. The patent describes the method and process of how NBT2 is constructed and are described more in paten document No. WO 01/94191 A1.

    20 different criteria have been developed which have also been approved by the project stakeholders. A survey was done early in the project where we consulted a number of people who have good insight into the product. The criteria are only part of the work of what WP1 will perform where the goal is a completed computer-based design systems. The report includes a description of what this computer based design system will perform. The various digital tools and utilities that will be used are explained in the report.

    There are still information missing from the rest of the WP inside the project which has force Wp1 to perform a series of tensile tests where the goal is to find a template for how to use materials from product geometric design. The goal is that this computer-based design system should be ready in late 2010.

    Optimizing Products and Production Using Additive Manufacturing by Introducing Bionics into the Engineering Design Process2017Ingår i: ASME 2017 International Mechanical Engineering Congress and Exposition, New York: ASME Press, 2017, artikel-id V011T15A017Konferensbidrag (Refereegranskat)
    Abstract [en]

    In order to perform engineering design activities aiming at the design of new or redesign of existing products, a number of alternative processes, methods and techniques are available in the literature to the engineering designer/product developing enterprise. These processes, methods and techniques, are usually not explicitly expressed in terms of directives as to when and how they are to be used in the actual design of the product-to-be.

    An important goal in product development of today is to fulfill the terms for sustainable development, thus emphasizing the need to develop products which are not overexploiting the available resources provided by nature. By utilizing an approach to development and design based on bionics, i.e. utilizing biological methods and systems found in nature as a means of creating technical solutions, a conceptual framework is provided which is especially fit to accommodate the striving for sustainability.

    Striving for lightweight designs provides a significant potential to reduce the energy consumption of the product-to-be, which at present is a highly prioritized goal within sustainable development. Up until now, the dominating approach to lightweight designs has been to utilize lightweight materials such as different types of composites and metallic materials such as aluminum, magnesium and titanium.

    By introducing biomimicry into the engineering design process, an additional step towards efficient lightweight design solutions might be within reach. Since the objects created by nature are independent of costs and time, these are most often very complex especially regarding shapes and dimensions. In order to match these constraints in the creation of technical solutions (products), it is necessary to utilize optimization in combination with a flexible manufacturing process. The ideal manufacturing method to meet these demands is Additive Manufacturing (AM), though, at least for the time being, it imposes some constraints in size, costs etc. of the product to be manufactured.

    If the product designed is to be suitable for manufacturing for AM, it must be optimized, and so must the way it is to be processed. Therefore three of the most essential problems which need to be addressed in order to efficiently utilize AM are also elaborated upon and reported in the paper.

    The first of these problems is how to optimize the product-to-be. The second is to establish the orientation in which the product is to be manufactured during the AM process. The third is to find the best usage of the support material in the 3D printer, as there is no optimized process available for this activity. This is mainly due to the difficulties to foresee the waste of building material as, in most cases, this material can only be used once.

    In this paper, a process for the design and development of new products is proposed. The application of the process also includes essential elements to assure an efficient use of AM as mentioned above. The process is established on the basis of an integration of the Biomimicry Design Spiral, Bionic Structures and Elements and optimization into the Engineering Design Process. The utilization of the process is demonstrated by an application and reported in the form of a modified engineering design process — the Engineering Design and Biomimicry Design Process or the EDBP process for short.

    Template-Based Design Analysis: An Alternative Approach for the Engineering Designer to Perform Computer-Based Design Analysis2016Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [sv]

    Vid framtagning av nya produkter måste man utgå ifrån de behov som den blivande kunden ställer i form av krav och önskemål på produkten för att den ska vara intressant att inhandla och använda. För att säkerställa att den blivande produkten har de egenskaper som efterfrågas, används idag omfattande simuleringar av den blivande produktens egenskaper. Simuleringar består i avancerade beräkningar med hjälp av dator. Genom att utföra dessa tidigt i utvecklingsarbetet, så kan man väsentligen korta ned tiden för utveckling och konstruktion av produkten. Detta uppnås framför allt genom att minska behovet av att bygga och prova prototyper. Beräkningar i utvecklings- och konstruktionsarbetet spelar därför idag en väsentlig roll för att ta fram konkurrenskraftiga produkter på ett snabbt och effektivt sätt.

    I denna avhandling har ett nytt tillvägagångssätt tagits fram för att låta konstruktörer själva beräkna sina konstruktionsförslag. Hittills har merparten av alla beräkningar av detta slag genomförts av beräkningsingenjörer. Nu kan man genom att tillämpa den i avhandlingen framtagna tillvägagångssättet att med hjälp av digitala mallar (program för att lösa speciella uppgifter i konstruktionsarbetet) och det föreslagna tillvägagångssättet MallBaserad KonstruktionsAnalys (MBKA) tillåta att konstruktörer, som vanligtvis inte är specialister på beräkningar, självständigt kan utföra sådana analyser. Mallarnas roll är alltså att överbrygga brister i kompetens och erfarenheter av konstruktionsberäkningar.

    Redan idag finns konkurrerande sätt att tillåta konstruktörer att delta i beräkningsarbetet, men då oftast med direkt stöd av en beräkningsingenjör och med tillgång till riktlinjer. Dessa kräver att konstruktören har en viss grundkompetens för att kunna följa och tillämpa dessa. MBKA ställer inte dessa krav på kompetens och insikter, vilket gör att den kan betraktas inte bara som en konkurrent till existerande tillvägagångssätt utan också erbjuda ett helt unikt och nytt stöd genom att inte kräva kunskaper och insikter om konstruktionsberäkningar.

    Av de reaktioner som erhållits i intervjuer i svensk industri, så ter sig framtiden för MBKA som mycket lovande. Många företag funderar redan idag på att införa tillvägagångssättet. Innan så kan ske, måste dock MBKA utvecklas ytterligare, vilket är målet för den fortsatta forskningen.

    Carbon Fiber Composite Materials in Modern Day Automotive Production Lines – A Case Study2013Ingår i: ASME 2013 International Mechanical Engineering Congress and Exposition: Volume 2A: Advanced Manufacturing, New York: ASME Press, 2013, artikel-id V02AT02A037Konferensbidrag (Refereegranskat)
    Abstract [en]

    New and innovative production equipment can be developed by introducing lightweight materials in modern day automotive industry production lines. The properties of these new materials are expected to result in improved ergonomics, energy savings, increased flexibility and more robust equipment, which in the end will result in enhanced productivity. Carbon composite materials are one such alternative that has excellent material properties. These properties are well documented, and the market for carbon composite materials is growing in many areas such as commercial aircrafts, sporting goods and wind turbines. However, when studying the use of carbon composite materials for production equipment in the automotive industry, it was found that there were few, if any, such examples.

    This paper focuses on innovative ways of making carbon composite materials available for designing automotive industry production equipment by introducing a design and material concept that combines flexibility, relatively low costs and high functionality. By reducing the weight by 60%, it was obvious that the operators were very positive to the new design. But just as important as the improvement of the ergonomic feature, the combination of low weight and material properties resulted in a more robust design and a more stable process of operation. The two main designs (two versions of the steel-based design were constructed) were developed sequentially, making it difficult to compare development costs since knowledge migrated from one project to the next. In this study, the gripper was manufactured in both carbon composite material and steel. The different designs were compared with reference to design costs, functionality, robustness, product costs and ergonomics. The study clearly shows that the composite material represents a favorable alternative to conventional materials, as the system combines superior properties without significantly increasing the cost of the equipment. This paper describes the approach in detail. Copyright © 2013 by ASME

    In their quest for a more efficient and effective utilization of the resources allocated to engineering design projects, and thus to the overall product development project from which the current design task(s) originate, an increasing number of companies allow engineering designers to perform Computer-Based Design Analysis (CBDA) on their own – CBDA is here confined to quantitative analyses using finite element-based structural and thermal analyses, Computational Fluid Dynamics, and Multi-Body Systems. Since all of these tools require a certain level of expertise in order to be successfully utilized in industrial practice, the types of analyses performed by the engineering designers are confined to simple, straightforward ones.

    In striving for an increase of the individual engineering designer’s possibilities to actively participate in CBDA in industrial practice, an online survey has been carried out and reported in [1]. The main objective set out for this survey was to give an overview of the current situation in the global industry regarding CBDA-tasks being performed by engineering designers, what positive effects it might present to the industry and how it should be implemented for best result. Resulting from this survey, one new support, Template Based Design Analysis (TBDA), singled out as very promising for future development. TBDA is a support to be used in engineering design analyses based on the utilization of the advanced features provided by high-end Computer Aided Design (CAD)/Computer Aided Engineering (CAE) software in supporting, guiding as well as monitoring the design analysis performed by the engineering designer. It was also found that TBDA was gradually being introduced in some industrial companies.

    Since TBDA is still in its infancy, substantial development needs to be invested in it to make it the full-blown support needed in industrial practice. To be able to contribute to the development of TBDA, it is essential to acquire knowledge about how companies, both national and international, are planning to introduce and utilize TBDA in industrial practice.

    To that end a new online survey has been carried out, focusing on the introduction and benefits associated with TBDA. Out of a total of 64 respondents, 41 of the these were selected from the previous survey [1] and 23 came from companies known to the authors to utilize CBDA on a regular basis; these 23 were invited to participate in the interviews and as a first step, before carrying out the interviews, all of them were requested to answer the survey. 42 of them, from 17 countries, completed the online-survey. In addition to this survey, 5 Swedish companies, all utilizing CBDA on a regular basis, were participating in qualitative interviews. The main objective was to get an in-depth view on the use of engineering designers performing CBDA as well as an indication on the validity of the responses obtained in the online survey by comparing the results from the interviews and the companies response to the online survey – all companies interviewed answered the online survey in advance before the interviews were carried out.

    The introduction of TBDA in an industrial setting has resulted in many advantages, such as shorter lead times, opportunities to generate more concept candidates, and increased collaboration between the engineering designers and the design analysts, all of them contributing to more mature technical solutions. Three different automation levels of TBDA have also been identified and accounted for as well as being exemplified. In the companies in which TBDA has not been implemented, some of the reasons for not doing so are high costs, company policy, and the lack of knowledge and experience on the part of the engineering designer. This paper presents the results both from the new online survey as well as from the interviews. © 2015 by ASME

    A Computer-Based Design System For Lightweight Grippers in The Automotive Industry2013Ingår i: Proceedings of the ASME International Mechanical Engineering Congress and Exposition--2012: presented at ASME 2012 International Mechanical Engineering Congress and Exposition, November 9-15, 2012 Houston, Texas USA, New York: ASME Press, 2013, Vol. 3, s. 169-179Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents the development as well as the architecture of a computer-Aided dedicated fixture design system intended to support the design of lightweight (carbon fiber composite) grippers for a major truck company. Lightweight grippers were required due to the increasing production rates in the automotive industry. The current robotic equipment was facing diverse problems during transportation and aligning of the parts, problems related to mass inertia, accuracy and stability. Moreover, the increased demands for truck customization and fast release of new product versions required a computer-based support for the design of the appropriate fixtures. This application is believed to be of interest for fixture research because the design of such complex fixtures is likely to appear more and more often. Specifically, such fixtures are subject to specific requirements that necessitate a systematic requirement elicitation method; they also require extensive conceptual design work as well as careful analysis activity planning. The main steps requisite for the development of the design system are reported: setup planning, fixture planning, conceptual design of the gripper. The architecture, the process and the constituent elements of the design system are also described and illustrated. Copyright © 2012 by ASME.

    Integration of Computer Aided Design Analysis into the Engineering Design Process for use by Engineering Designers2013Ingår i: ASME 2013 International Mechanical Engineering Congress and Exposition: Volume 12: Systems and Design, New York: ASME Press, 2013, Vol. 12Konferensbidrag (Refereegranskat)
    Abstract [en]

    When developing products, engineering designers often face the problem that their candidate for a technical solution, ranging from a concept to a detailed design, needs to be analyzed by a design analyst before it is approved or rejected and the engineering designer can continue his/her activities within the product development process. If engineering designers have to send every solution candidate to a design analyst, a lot of time and money is lost. To avoid this, some Swedish companies have started to allow their engineering designers to use the analysis capabilities imbedded in modern CAD/CAE software.

              In the literature on product development and on computer based design analysis (CBDA) both processes are fairly well described. However, this cannot be said about the interaction between the two processes. This is a growing issue as it represents core knowledge for developing efficient and effective integration concepts, which in turn can be developed into likewise efficient and effective approaches on how to assist the engineering designer to perform parts of the CBDA process on his/her own. Note that when we refer to CBDA here, this is confined to the use of FEM in the development of products, primarily based on working principles originating from the area of Mechanical Engineering.

              Since we have been working on a process model for the integration between engineering design and design analysis, this has inspired us to utilize findings from these efforts to propose a conceptual model for a design analysis process driven by the engineering designer to be integrated into the product development process.

              The proposed design analysis process model is based on the use of predefined analysis methods or templates. Templates are also utilized for QA (Quality Assurance) and monitoring of the analysis activities. Responsible for the development of the analysis methods and the templates are expert design analysts, who develop these tools within a technology development process. Before allowing the engineering designers access to them, these tools need to be approved by relevant bodies within the industrial enterprise and/or by external sources such as those responsible for certification and risk management.

              In this paper we present the development of the proposed integrated design analysis process model and an industrial case study, which incorporates a non-linear design analysis activity, utilizing the FEM-program Abaqus within the CAD-software Catia V5 and its imbedded optimization module.

    Reduction of heat loss for an immersion heater2017Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    In this study, an electrical immersion heater mounted on a water tank has been investigated. Themain aim was to reduce heat transfer and to utilize the maximum energy available from heater toheat the water. To observe the effects of essential geometrical and operating parameters on thesystem performance, different computational test cases were run for three different designs.In the first case of simulation, the immersion heater of existing design mounted on a water tankhas been analyzed. The cold-water tank with inlet and outlet and given appropriate boundaryconditions was used to see the temperature contours inside the water tank and temperature of theimmersion layer itself.In the second case, an insulation plate has been introduced in the immersion heater head in orderto reduce heat loss by considering the possible heat leakage through the gap inside the heaterhead by radiation.In the third case, an insulation ring has been introduced in the immersion heater head as asubstitute for the insulation plate which has the same aim as second case.The results obtained from the CFD simulation shows the thermal performance of immersionheater in a water tank for three different cases. The results are helpful in optimizing both heatingelement and immersion heater by introducing different changes to optimize the design. It showsthat the redesigned immersion heater and storage tank can provide improved working conditions.Also, at early design stages, CFD simulations could be used as an effective tool to optimizethermal storage tank parameters, so it may add value to the storage tank and immersion heaterperformance and efficiency, by optimizing the whole thermal heating system design and size.Different materials and geometry design are tested giving the minimum heat losses from thesystem and uniform temperature distribution in the water heater.

    Redesign of needle positioning system for breast biopsy: Cytoguide, the world's first fully automated positioning intrument for breast biopsy2019Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This thesis document is a detailed description of the redesign of a breast biopsy needlepositioning system. It describes the current machine and its problem, an outdated drivingsystem, as well as giving a general understanding of taking a breast biopsy. Thisto clarify the topic to the reader and giving them a better understanding and to designa more complete product. This introduction was followed up by a research part aboutcontemporary driving and guiding systems. By the use of a morphology and decisionmatrix as well as a meeting with the company it was soon decided that linear guiderails in combination with a special type of stepper motors was the best solution forthe problem. After this decision was made, the project continued by making a detailedCAD model. The biggest challenge here was making the machine as compact as possible.With the design choices made, the result is a machine which is as compact as it canget. The last stage of the project was doing a verification. This was already partly donein deciding which stepper motors and linear guide rails were suitable. However, checkingif the machine would be able to handle the forces specified in the list of demandsand wishes still had to be done and is executed with the use of FEM. After the FEManalysis was executed it was soon concluded that the stress limit of the aluminum alloywas not reached and the maximum deflection was below the limit. A few demands wereleft untested because it would require a prototype made of its actual components andmaterials used for the production machines.

    Abstract [en]

    The importance of surface finish in all aspects of manufacturing influences economic considerations as well as environmental aspects and functionality. The ability to effective and efficient characterise surface topography is an important tool in the manufacturers arsenal which is often overlooked or underutilised. By providing a comprehensive, affordable training package, a gap in the industrial knowledge is filled giving manufacturers the ability to increase their competitive edge.

    Detection of paint polishing defects2018Ingår i: Surface Topography: Metrology and Properties, ISSN 2051-672X, Vol. 6, nr 2, artikel-id 024009Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Surface finish plays a major role on perceived product quality, and is the first thing a potential buyer sees. Today end-of-line repairs of the body of cars and trucks are inevitably to secure required surface quality. Defects that occur in the paint shop, like dust particles, are eliminated by manual sanding/polishing which lead to other types of defects when the last polishing step is not performed correctly or not fully completed. One of those defects is known as 'polishing roses' or holograms, which are incredibly hard to detect in artificial light but are clearly visible in sunlight.

    This paper will present the first tests with a measurement set-up newly developed to measure and analyse polishing roses. The results showed good correlations to human visual evaluations where repaired panels were estimated based on the defects' intensity, severity and viewing angle.

    A decision framework for outsourcing of new product development2008Ingår i: Manufacturing fundamentals: necessity and sufficiency: Proceedings of 3rd World Conference on Production and Operations Management / [ed] Amasaka, K., Matsui, Y., Matsuo, H. & Morita, M., Tokyo: POM , 2008, s. 1390-1405Konferensbidrag (Refereegranskat)
    Abstract [en]

    This article focuses on the outsourcing of NPD in medium sized firms and especially the decisions connected to outsourcing. Although the framework is probably also useful for small and large firms, the three empirical studies the results explored samples of medium sized firms. NPD is a knowledge intensive activity that requires the ability to handle uncertainties and it is very dependent on the individuals involved in the process. In this way it differs from production, which (especially when producing standard items on a large scale) is easier to control, monitor and to evaluate the costs. Outsourcing can lead to advantages in form of lower costs, access to knowledge or other resources, as well as access to markets, but it can also result in a knowledge drain, lower motivation among in-house staff, or an increased level of dependency on external organizations. A decision framework is presented that describe the decisions process when outsourcing NPD.

    Effects of knowledge integration on innovation performance: A framework and empirical study2009Ingår i: Proceedings of the 16th International Product Development Management Conference (IPDMC'09), Twente: EIASM , 2009, s. 23-Konferensbidrag (Refereegranskat)
    Abstract [en]

    PURPOSE – To provide empirical evidence to support the effect of a firm’s ability to integrate knowledge on the innovation performance of a firm, and to examine the different effects of three categories of knowledge.

    DESIGN/METHODOLOGY/APPROACH – Data were collected using an e-survey sent to R&D managers representing firms with between 100-800 employees from a cross-section of industries. A total of 355 firms were addressed and 193 questionnaires were returned and usable (54.4% response rate). Hypotheses were tested using multiple regression analysis with and without interaction terms.

    FINDINGS – Results indicate that ability to integrate thematic knowledge is significantly related to innovation performance. There is also a less significant indication that product properties, as product complexity and newness, have a positively moderating effect on the above relation.

    RESEARCH LIMITATIONS – The sample represented medium sized firms. The data were collected in Sweden. As with most studies, it is important to replicate this study in different contexts.

    PRACTICAL IMPLICATIONS – The study offers a suggestion to how managers can focus their efforts in order to improve their ability to integrate knowledge from product development projects.

    Este documento presenta los resultados de un estudio realizado en cuatro empresas suecas, de mediano tamaño, para entender los razonamientos detrás del outsourcing en la innovación. Se aborda especialmente el problema de integrar conocimiento desarrollado en la empresa que requiere el outsourcing, esto es analizado, evidenciando oportunidades de mejora. Los resultados indican que para las pequeñas y medianas empresas (PYME), con recursos limitados, puede ser mejor dar prioridad a la proximidad entre empresas antes que al conocimiento de punta, es crucial mantener cercanía y contacto frecuente durante el proceso de outsourcing en aquellas actividades intensivas en conocimiento.

    Abstract [en]

    The purpose of this study is to examine the effect of a firm’s ability to integrate knowledge on their innovation performance, in order to help firms prioritize their resources used for knowledge integration more effectively. Data were collected from a survey mailed to R&D managers in firms with between 100-1000 employees in a cross-section of industries. Five hypotheses were tested using multiple regression analysis with and without interaction terms. The results indicate that a categorization of knowledge is useful for understanding knowledge integration. The study also shows that the ability to integrate domain-specific knowledge is significantly related to innovation performance. Furthermore, the results indicate that technology turbulence in the industry has a positive moderating effect on the above relation. Managerial implications suggest how managers can focus their efforts in order to effectively integrate knowledge in product development projects. © Imperial College Press.

    World-class or Good Enough: The Choice of Partner when Outsourcing New Product Development in Medium-Sized Firms2008Ingår i: International Journal of Innovation and Technology Management (IJITM), ISSN 0219-8770, Vol. 5, nr 4, s. 423-445Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Research on outsourcing normally focuses on outsourcing of production and often uses large firms as samples. Only a few studies address the outsourcing of services or knowledge-intensive activities such as new product development (NPD), and especially in the context of medium-sized firms. Our earlier research in medium-sized firms indicates that outsourcing of NPD is frequent in medium-sized firms, and that there is a lack of knowledge about the phenomenon. This article offers a theoretical framework to study the outsourcing of NPD, and includes the results from a longitudinal case study carried out in six Swedish medium-sized firms to help understand the rationales behind outsourcing of NPD. Results from the present study indicate that ‘good enough’ is the keyword for medium-sized firms with limited resources. This means that it is considered more important with proximity and trust than world class competence, since close and frequent contacts are crucial, when outsourcing knowledge-intensive activities such as NPD. A conceptual model and a definition of the good enough concept are also presented.

    Outsourcing of NPD Activities: A best practice approach2010Ingår i: European Journal of Innovation Management, ISSN 1460-1060, E-ISSN 1758-7115, Vol. 13, nr 1, s. 5-23Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose – The purpose of this paper is to improve our understanding of outsourcing NPD, and specifically of factors affecting the outsourcing decisions, by exploring the practices of the most innovative firms.

    Design/methodology/approach – An internet based survey sent in winter 2008 to 494 medium-sized firms in four industries. The response rate was 77.3%. Sample was split into the best firms and the rest, and a best practice analysis was performed with correlation analysis.

    Findings – The best firms focus on knowledge issues to a higher extent, while cost and geographical proximity are more important for the rest firms. The best firms prioritize knowledge integration and development of knowledge about the outsourcing process higher.

    Research limitations/implications - The sample is taken from medium-sized Swedish manufacturing firms. Future samples need to be expanded to further generalize the conclusions. Results show that further research combining resource and cost perspectives are needed.

    Practical implications – Managers are recommended to not only find access to needed knowledge, but also give time to integration on a personal level, as this protect knowledge and lower costs in the long run.

    Originality/value – Studies of outsourcing NPD are few and, to our knowledge, no quantitative studies on the topic have been made.

    Factors affecting Organizational Acceptance of Formal NPD Processes2010Konferensbidrag (Refereegranskat)
    Abstract [en]

    Purpose – The aim of this paper is to improve the understanding of organizationallevel factors affecting the degree of acceptance and use of formal new product development (NPD) processes, which in turn may lead to enhanced NPD performance.

    Research design – For data collection, an internet based survey was made available to employees working for nine large manufacturers of commercial vehicles worldwide. The total sample analyzed in this study contained N=254 respondents corresponding to a response rate of 26%. The data was analyzed based on a hypothesized research model using structural equation modelling technique (SEM).

    Findings – We present and validate a research model of formal new product development process acceptance. The study shows that acceptance of formal NPD processes is determined by several factors, such as ease of use, transparency of discourse, continuous improvement, involvement of NPD actors, as well as their ability to bridge differences in thinking. Furthermore, it is shown that acceptance of formal NPD process affects NPD performance positively.

    Research limitations – The sample is taken from the commercial vehicle industry. Further samples from other industries need to be collected in order to show general validity of the insights gained in this study. Further research should also concentrate on medial and cultural dimensions of the model proposed.

    Managerial implications – This study provides detailed recommendations to NPD managers on how to facilitate organizationallevel acceptance of formal NPD processes and thereby enhancing NPD performance. Managerial implications include, for example, design recommendations for formal NPD processes, the use of sophisticated media for formal NPD process management, as well as the promotion of a culture of cross-functional exchange.

    Originality – Quantitative studies on potential determinants of formal NPD process acceptance are scarce. This study approaches the issue from a socio-cognitive perspective, underscoring the importance of organic bottom-up approaches to formal NPD process management.

    The Effects of Knowledge Integration on New Product Development Performance2011Ingår i: School of Business, NFF 2011 August 20-24, Stockholm: Stockholm University, 2011, s. 132-132Konferensbidrag (Refereegranskat)
    Abstract [en]

    The knowledge needed for development of new products is becoming increasingly complex and distributed. There is a need for firms to develop their capabilities for knowledge integration. Although prior knowledge-based literature has pointed to the importance of knowledge integration for competitive advantage, our understanding of how the integration of different types of knowledge affects new product development (NPD) performance is still limited. We quantitatively examine the effect of the integration of different types of knowledge on performance in NPD. Knowledge integration refers to the process of combining specialized but complementary knowledge. In this article we seek to study the effects of knowledge integration on NPD performance. Previous studies point to the positive effects of knowledge integration on NPD performance, but they do not distinguish between different types of knowledge in examining these effects. This article therefore seeks to contribute to this emerging literature by explicitly studying the integration of different types of knowledge and the effects that such integration have on NPD performance. We draw upon a classification of knowledge suggested by Ullman (1997) in discussing what types of knowledge that is particularly pertinent in engineering practices. That is, what knowledge engineers draw upon in conducting design and development work. We address the types of domain-specific knowledge, procedural knowledge, and general knowledge integration. Three hypotheses suggesting that the capabilities for integration of each type of knowledge respectively affect NPD performance positively are tested. A fourth hypothesis suggests that there are complementarity effects between integration of the three types of knowledge upon NPD performance. Data was collected during 2009 from a sampling frame of 355 medium-sized Swedish manufacturing firms in four industries. We received 193 valid answers, i.e. a 54% response rate) Hypotheses were tested with standard OLS regression together with EFA and CFA analysis. The results provide support for the first three hypotheses, while the fourth one was rejected. This implies that capabilities to integrate domain-specific, procedural and general knowledge are all independently affecting NPD performance positively, but no combined effect above and beyond the individual variables. This indicates that one knowledge type can be integrated without an absolute need to integrate two types or all three types.

    Utveckling av medicintekniskt instrument för mätning av muskelstyrka2013Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Detta examensarbete inom biomekanik var ett produktutvecklingsprojekt av ett medicintekniskt instrument för mätning av statisk muskelstyrka i lårmuskulaturen (quadriceps). Instrumentet utvecklades med utgångspunkt från instrumentet Stig Starke som blivit föråldrat och förfallet. Stig Starke nyttjas främst av sjukgymnaster på Sahlgrenska universitetssjukhuset med syfte att exempelvis utvärdera effekter av sjukgymnastisk behandling. Behovet av en ny version av instrumentet är stort både inom kliniskt arbete och inom forskning. En ny version av instrumentet skulle hjälpa sjukgymnaster och forskare till att kunna fortsätta mäta muskelstyrkan i quadriceps på ett snabbt och enkelt sätt.

    Syftet och målsättningen med detta examensarbete var att utveckla Stig Starke-instrumentet så att mätningar av maximal statisk styrka i lårmuskulaturen (quadriceps), i enheten Newton, kan göras på patienter inom sjukvård och rehabilitering. En problemanalys i form av Workshop gjordes hos användarna på Sahlgrenska universitetssjukhuset. Problemanalysen tillsammans med en förstudie lade grunden för koncept i form av krav och önskemål till nya versionen av instrumentet. Önskemål på användarvänlighet av instrumentet och standardisering av patientens kroppsposition stod högt i prioritering.

    Via dynamisk produktutveckling och biomekaniska metoder där användarna (sjukgymnasterna) var i fokus kunde ett koncept väljas ut och tillverkas till en funktionell prototyp. Sex nyckelord för arbetet är quadriceps, muskelkraft, instrument, antropometri, användarvänlighet och standardisering. Funktionella prototypen visade via produktutvärdering att goda utvecklingsmöjligheter finns för den nya versionen, då den visade på hög användarvänlighet och standardisering. Behovet av en ny version av instrumentet kommer att finnas kvar tills ett likvärdigt instrument som Stig Starke kan tillämpas i verkligheten.

    3D-Bodycanning: A market research based approach for rotary table selection2017Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    This report provides a recommendation for the purchase of a rotary table intendedmainly for 3D body scanning. This recommendation is presented to FabLab,Halmstad University. The proposal is based on the needs and requirements discussed and defined among group members, clients and other stakeholders. The main requirement is that the product can be programmed and controlled by acomputer. This requirement was strengthened through the execution of a pairwise comparison. A broad market research is described and methods that have been used to achieve the results. In order to better understand how much the load will affect the product, a force measurement test was performed and analyzed. Earlier reports about reverse engineering, different applications and scanning techniques provide a deeper understanding of factors that may affect the selection of the product.

    Measurement of Surface Defects in 3D Printed Models2016Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The ease of manufacturing using additive manufacturing (3D-Printing) reduces the overall production cost compared with the traditional manufacturing techniques. Because of the benefits of 3D printing technologies, it is proposed to be used in manufacturing of different products. But there are some flaws that are causing significant effect on 3D printed models which degrades the quality of the product. Hence in order to handle these defects, different measurement techniques are needed to quantify the defects that are seen on the surface of 3D-printed models. In our study there are two experimental setups. Experimental setup one was made to find out the proper coating timing to enable measurement using two good samples without defects in different colors blue and red with same material. Different 2D and 3D parameters were used for the surface measurements are collected and noted for further research. The Defective samples are measured using the state of the art equipment at Halmstad University. Experimental setup two was made to prepare the defective samples and measure the samples. The results obtained assisted to quantify the surface defects seen in the samples. This thesis studies some of the different methods that can be implemented to measure the surface defects on the 3D printed models. A little study on the various defects formed on the 3D printed models and what are the causes for the defects on the products were performed. The results suggest different method for the defects to be measured in both industrial and home or small scale office applications.

    Easy Click: Det lättmonterade glashuset2010Självständigt arbete på grundnivå (kandidatexamen), 15 poäng / 22,5 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Problemet med dagens växthus är framförallt den komplexa och tidsödande monteringen. Monteringsanvisningarna är knapphändiga och det är inte ovanligt att det tar två dagar att montera ett växthus. Examensarbetet har därför fokuserat på utformningen och monteringsmetoden av aluminiumprofilerna som används till växthus. Detta resulterade i Easy Click, det lättmonterade glashuset.

    Easy Click är ett glashus helt utan skruvar;  istället används smarta spår och snäppförband som har integrerats i profilerna. Detta gör att profilerna är mycket lätta att tillverka, bland annat på grund av att de inte behöver förses med skruvhål. Glashuset är såväl lättmonterat och exklusivt som lättilverkat och både projektgruppen och uppdragsgivaren är väldigt nöjda med resultatet

    FÖRBÄTTRAD MONTERING OCH DESIGNAV BAGAGELUCKA2015Självständigt arbete på grundnivå (högskoleexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Detta examensarbete omfattar ett maskintekniskt konstruktionsarbete som är gjorti ett samarbete mellan ÅF och Högskolan i Halmstad. Arbetet är utfört utifrånFredy Olssons metoder för Princip- och Primärkonstruktion samt David Ullmansteorier kring Design for Assembly.Gruppen fick i uppdrag av ÅF att ta fram ett koncept för att minskamonteringstiden av dagens bagageluckor på turistbussar genom att minska antaljusteringsmöjligheter på dagens konstruktion. De hade även en önskan om attgruppen skulle förenkla monteringen genom att göra det möjligt att justera dörreni stängt läge. Dagens luckor tar, med sina 10 justeringsmöjligheter, cirka 4 timmarvar att montera och ÅF önskade en monteringstid på ca 10 minuter per dörr.Inledningsvis gjordes en förstudie där gruppen började granska dagenskonstruktion och montering för skenor och luckor på bussar. Det man tog med sigvar att dagens tillvägagångssätt för att öppna bagageluckan fortfarande är attföredra. En ytterligare aspekt som togs i åtanke var att monteringen skulle bli merergonomisk för montören.Tre koncept togs fram från kriterierna. Koncept 3 som bestod utav en ram somjusteras mot bagageluckans öppning var det bästa alternativet. För att ta fram denbästa konstruktionen av ramen med tillhörande komponenter använde gruppenolika utvärderingsmallar samt FEM-analyser för att konstatera att konstruktionenvar tillräckligt hållbar.Resultatet av projektet blev ett koncept där man fäster ramhållare mot dagensskenor. På dessa fästes en ram och sedan en klickdörr. Ramhållaren har tre krokarsom man hakar fast ramen på och efter justering mot bagageluckans öppning såklickas dörren fast utanpå ramen. Ramen kan justeras i stängt läge. Denna lösningresulterar i att monteringsflödet blir lättare men antalet justeringsmöjligheter frånförgående koncept finns kvar. Det ergonomiska arbetet för montören underlättatsoch monteringstiden är kraftigt reducerad.
