    User-centered design of an attachable battery pack for arborists2019Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Globe Group, som står bakom varumärket Greenworks Tools, är branschledande inom batteridriven utomhusutrustning och levererar verktyg med samma prestandanivå som hos ett bensindrivet verktyg, fast utan utsläpp och krångel som det typiskt är förknippat med. Bensindrivna verktyg är fortfarande mycket vanliga inom trädvårdssektorn där arborister arbetar med motorsågar dagligen vid trädfällning och grenbeskärning.

    Nu är en ny typ av motorsåg under utveckling av Globe Group som kännetecknas av sin lätta vikt och stora batterikapacitet, vilket ger extra lång batterilivslängd. Denna kombination är möjligt genom att ha ett externt batteri vilket är huserat i ett separat batteripaket istället för att placera batteriet direkt in i verktyget. Projektets mål är att anpassa och konstruera batterifickan specifikt för målgruppen arborister genom att använda en användarcentrerad designapproach med fokus på ergonomi. Detta görs genom ett nära samarbete med arboristerna under hela projektets gång, från förstudie till utvärdering av resultat, för att utforska och uppfylla användarens behov. Ett slutligt koncept är utvecklat för att tillgodose både användarens och företagets behov/krav.

    Smart manufacturing support to product platforms in industrialized house building2019Konferensbidrag (Refereegranskat)
    Abstract [en]

    Swedish house building companies currently face many challenges in terms of fluctuating market demand, need for flexible product offering, non-uniform governmental regulations, high costs, and long lead times. These challenges affect both internal and external efficiency of companies. Product platforms have been used for more than a decade in this industry to improve both internal and external efficiency. However, the industry is still criticized for its inefficient and costly process. Smart manufacturing has emerged as means to improve the efficiency of internal processes and the question is if and how smart manufacturing can complement and support product platforms in industrialized house building. The aim of this study is to explore the potential of smart manufacturing to complement and support product platforms in theory and practice in the context of industrialized house building. A literature review and a multiple case study were chosen to fulfill the study objective. In total fourteen semi-structured interviews were conducted in two timber house building companies. The data was analyzed within and across cases using four platform assets for categorization: components, processes, knowledge and relationships. The results show that the smart manufacturing technologies are in both theory and practice mainly supporting the process platform asset through developing vertical and horizontal IT systems integration, definition and digitalization of flexible building systems, and transferring explicit drafting and engineering knowledge into parametric modelling tools.

    Knowledge Base Engineering Design Methodology and Integration with PLM System Part Factory2019Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Companies are trying to decrease product expenses while customizing product according to customers requirements. So to satisfy the customers’ requirements, companies must adapt their business to mass customisation.  Mass customization final product goes through all flexible company production technology process, which can lead to being expensive and time-consuming and because of this, a product configuration system is developed to reduce product cost and reduce time. The primary focus of this thesis is to develop a KBE prototype using constraint-based techniques of product configurations. For developing KBE implementation of  UML/OCL, XML, Backtracking search is used. Then prototype expert configurator is developed using OCL constraints.

    Concept Development of an Inflatable Roof Box using Drop-Stitch Fabric2019Självständigt arbete på avancerad nivå (masterexamen), 20 poäng / 30 hpStudentuppsats (Examensarbete)
    Abstract [en]

    The purpose of this project is to design a roof box for Urban users living in modern houses. Usually, the compactness of these houses does not allow the luxury of owning traditional hard-shelled roof boxes. Taking inspiration from the inflatable technology used in stand-up paddleboards and kayaks, this project explores the possibility of implementing the drop-stitch material for fabricating an inflatable roof box.

    The drop stitch fabric was first developed in the early 1950s by Goodyear for their inflatable aeroplanes. Although most of its early applications were classified by the military, the drop stitch material is presently being implemented in various products such as Kayak, AirTrack, Inflatable Cooler etc.

    The scope of this thesis remains within concept design, which is an early phase of product development. Following the three stages, background research, concept generation, and concept evaluation, the project implements various conventional and intuitive research methods, such as literature review, brainstorming, prototyping, testing etc.

    The project was a collaboration between Industrial Design and Product Development, which made it possible to view the project from different perspectives. It explores various design aspects, such as shape, form, curvatures, ergonomics etc. and engineering aspects, such as strength, stiffness and structural integrity.

    Challenges and critical success factors for the design phase in Swedish industrialised house building2019Ingår i: Proceedings of the 35th Annual ARCOM Conference, 2-4 September 2019, Leeds, UK / [ed] Gorse & C. J. Neilson, Association of Researchers in Construction Management (ARCOM), 2019, s. 34-43Konferensbidrag (Refereegranskat)
    Abstract [en]

    The house building industry has been characterised as less productive compared to the manufacturing industry with numerous and challenging activities including a complex integration process. For the last 20 years, industrialised house building has gained increased research and industry attention and is identified as a potential way to improve the overall house building productivity. In the overall process, the design phase has been identified as the bottleneck with several disciplines which have to be coordinated to generate a design solution that meets various customer and market requirements. Many aspects of a building's performance depend on the decisions taken in the early design process. These decisions can have a substantial impact on the overall design, lead time, cost and quality of the final product. However, there are many other important factors which need to be considered by designers during the design phase. Less attention has been paid to the identification of these factors within the design phase of the industrialised house building. Thus, the main purpose of this paper is to identify challenges and outline the critical success factors to be considered in the design phase of the Swedish industrialised house building. Qualitative research was conducted in combination with literature reviews and multiple case studies linking three Swedish house building companies. Empirical data were gathered from 20 semi-structured interviews. The study identified common challenges in the house building industry and 20 critical factors that should be addressed in the design phase from both literature and practitioners view. The result shows that fixed production is crucial for identifying the critical factors rather than a building system. Also, many challenges identified from this study could be managed by developing a platform-based approach with support tools and methods for critical factors in the design phase.

    Development of Fluidity Measurement Technique and Automation of Measurement Station: Developing the existing Fluidity Measurement Station by automating the operation and measuring the fluidity digitally with MATLAB Image Processing Tools.2019Självständigt arbete på avancerad nivå (masterexamen), 80 poäng / 120 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Bryne AB has invented a device called Loop for measuring the fluidity of molten metal. Loop is made up of refractory fiber material and has a dimension of 196 sq.mm within which there is an engraved spiral shaped runway for the molten metal to flow. The distance traveled by the molten metal in the spiral determines its fluidity and is measured visually by the operator with the help of the spiral scale printed on the Loop. A workstation is used to support the Loop for an easier and better working environment. At present, the entire operation of fluidity measurement is done manually. The aim of the thesis is to develop an automatic workstation for the fluidity measurement and find a technique to measure the fluidity without human visual aid. Further, an attempt has been made to find a way to store and retrieve the measured values for future use.

     

    The automation of the workstation is done with the help of Arduino Uno circuit board for electrical connections and Arduino IDE for programming the circuit. MATLAB image processing tool is used for measuring the fluidity digitally.

     

    The prototype of the automated workstation is built and showcases the ability to reduce the time and operational errors. The automation of the unplugging operation saves up to 7 seconds.  The digital measuring of the fluidity with FLIR thermal camera and MATLAB image processing tool does not show significant improvement in accuracy in measurement, but it reduces the dependency on the expertise of the operator. There is an error of 12.7% from the actual fluidity value.
