This diploma thesis deals with analysis of the conformity assessment procedure of a torque converter body with its specification. The individual goals were to analyse the part specification, the current procedure for assessing compliance with the specification and to formulate practical recommendations. The first chapter is the introduction. The second chapter deals with the correct dimensioning of part geometry. In the third chapter, the customer's part specification was analysed. In the fourth chapter, the current conformity assessment procedure was analysed. In the last chapter, practical recommendations were presented.

In today’s society there is a growing awareness of where food is produced and there is a trend to use locally grown produce in restaurants. One way for restaurants to differentiate themselves is to grow the produce inside the restaurant. This thesis has the aim on identifying the problems and user needs for an indoor cultivation solution and developing a new indoor cultivation product that solves the identified problems and meet the user needs. To achieve this aim, a usercentered design approach was utilised and the following three research questions were answered: How can the needs of the user be translated into a product specification for indoor cultivation in restaurants? What are the functionality, usability, and construction requirements for an indoor cultivation product in a restaurant? What product concept can be designed to grow classic herbs in restaurants based on the needs of the user? To identify the needs interviews were performed with the users. The needs were then translated, together with the company’s needs, into a product specification. This was done in two steps, identifying the metrics and setting values. Some of the most important requirements are that a hydroponic system is used, that the product is easy to clean and is moveable. The product development process was iterative and included different ideation, development and evaluation methods. The users were involved in some of the evaluation methods to give input on the final design. Their opinion, together with evaluations based on the product specification, were used when choosing the final concept Lärad. Lärad uses a circulating hydroponic system and have three separate growing containers each containing 16 plants. The growing containers can be pulled out to enable easy access of the plants. Both the water system and the LED grow lights, that replaces natural sunlight, are controlled automatically to minimise the users’ involvement. To test the concept, to see how well the product specification is fulfilled, both a CAD model and a functional prototype were created. The results from the tests were, even at the concept stage, that 97% of all the tested requirements were fulfilled which shows that the concept is suitable for indoor cultivation in a restaurant environment. Some further work that includes refining the design and optimising for production will be needed to launch the product.

This thesis covers the development of a component specification for the steering system of vehicles engineered by CEVT. This includes the components steering column, intermediate shaft, steering gear and tie rods. Due to the reuse of requirements on the component specification from previous projects it now lacks connection to customer needs. A verification of the component specification is necessary to ensure that no redundant or unnecessary requirements are present. The verification was performed through a comparison between a newly established specification and the current one. Identified customer needs were gathered on complete vehicle level and classified according to customer satisfaction with respect to implementation according to the Kano model. The subjective customer needs were translated into objective, quantifiable metrics on complete vehicle level that was then decomposed onto component level. Customer needs and metrics were then correlated against each other and visualized through the House of Quality matrix. Numeric targets for the metrics were based on its impact on customer satisfaction. This resulted in 50 identified metrics connected to the steering column and 58 metrics connected to the steering gear. The comparison resulted in 22 deviations between the new and current specification where 8 metrics was identified for further investigation. Further development would include investigation of these 8 identified metrics and relate targets to competitors’ performance.

Bakgrunden till rapporten var att det företag som medverkat i studien ville utveckla ett grundmönster för damkappor. Syftet med arbetet blev därför att utarbeta ett grundmönster med två ärmtyper som graderas mellan storlek 32-50, samt konstruera en kappmodell från samma grund. Utöver detta skulle även detaljkonstruktioner och specifikationer utformas. Frågeställningarna som styrde arbetet kretsade därför kring hur man på bästa sätt tar fram detta.All konstruktion utfördes i Lectra´s Modaris. För att ta fram grundmönstret jämfördes två arbetssätt för att sedan välja en av de grunder som konstruerats. Efter detta gjordes nödvändiga ändringar utifrån avprovningar. Kappmodellen utarbetades genom kompletterande detaljkonstruktioner utifrån grundmönstret. Även de fristående detaljkonstruktionerna utformades på samma sätt. Specifikationerna togs fram i företagets PDM-system Quest PDM.Passformen hos grundmönstret blev god, ett mindre balansfel kan dock finnas kvar. Kappmodellen som syddes upp av produktionskontoret i Litauen motsvarade kraven. Ståkragen bland detaljkonstruktionerna kunde förbättrats, annars uppfyller även dessa konstruktioner kraven.Specifikationerna från Quest PDM visade krav och instruktioner tydligt. Dock var det problematiskt att använda flera olika ritprogram inom systemet.The background for this report was that the company cooperating with me wanted to develop a basic pattern for women´s coats. The purpose of this study was to construct a basic pattern with two types of sleeves to be graded in the sizes 32-50 and use the basic pattern to create a women´s coat. Beside this, coat details and product specifications should be produced.Lectra´s CAD-program Modaris is used for pattern construction. To create the basic pattern two different construction methods was used, and one of them chosen for further developing. The coat was developed from the basic pattern through additional constructions. The separate detail construktions was created be the same method. The companys PDM system Quest PDM was used to form the product specifications.The fit of the basic pattern was good, a minor balance fault might still remain. The coat sewn by the companys production office in Lithuenia met the requirements. The standing straight collar could be further improved, the other detail constructions lived up to the standars.The product specifications from Quest PDM showed the instructions and demands clearly. Unfortunately there was a problem using different illustration software within the system. / Program: Designteknikerutbildningen

Bakgrunden till denna rapport är att det sportvarumärke jag samarbetat med ville utveckla en modell av längdskidåkningsjacka som fanns i deras sortiment. Undersökningen gällde att identifiera förbättringspunkter på en dam- och herrvariant av denna jacka. Avsikten var att bevara plaggens design och genom förändringar i mönstrens konstruktion förbättra passform och rörelsefrihet, och därigenom plaggets funktion. Genom att konstruera, sy toiler och prova av dessa på provmodeller, har rörelsefrihet och passform kunnat utvärderas. Resultatet visade att viktiga punkter var raglanärmens konstruktion, böjningen av ärmen, kragens form, ärmhålsdjup och placering av skärlinjer. Det blev också tydligt att kombinationen av designerns och konstruktörens kunskaper tidigt i processen är a och o för ett lyckat resultat. En tydlig kommunikation mellan dessa parter kan minska antalet provplagg under produktutvecklingen.Ämnen som också behandlats under arbetet är gradering, produktspecificering och deras betydelse för plagg och produktion. I undersökningen har jag även tittat på möjligheter till ytterligare utveckling av jackornas funktion om designen kan förändras, till exempel genom att flytta skärningar och på så vis ändra modellens utseende.This study was made due to a sports brand wanting me to develop a style of cross country ski jacket that are currently part of their collection. The study contained identifying areas of possible improvement in both a men and women´s jacket. The mission was to keep the design of the jacket and on the same time improve the fit and ease of movement in the garment (and thereby the function). Through analysis of style samples, pattern construction, sewing of proto samples and fittings on models, the fit and ease of movement has been evaluated. The results are that important garment elements are the neck width, scye depth, construction of the raglan sleeve, the pre-bent sleeve and the placement of cut lines. A conclusion is that to reach a functional and nice looking garment, the designer and the pattern constructor need to cooperate in the product development phase. Good communication between these two departments can reduce the number of proto samples that has to be made.Pattern grading, product specifications and their impact on the style and production process are subjects that are also presented and discussed in this report. During the project I have also studied the possibilities of further development through style design changes. / Program: Designteknikerutbildningen

This master thesis report describes the development process of a modernized handguard for the AK4B battle rifle, which is the main armament for the Swedish Home Guard. The project was carried out in cooperation with ALTEN Sweden AB. The goal of the project was to develop a new, competitive handguard design and to establish a complete design documentation as a foundation for production. This documentation consisted of a final material selection, process plan with suitable manufacturing methods and engineering drawings. The project was initiated with a problem definition to establish a thorough understanding of the product to be improved and enabling a determination of aspects that might be of importance to the product development. From this, research areas could be selected and studied to acquire necessary insights to complete the project goals. The product development process implemented is mainly inspired by Ulrich & Eppinger, and includes the stages concept development, detail design and testing & refinement. Thus, well-established methodology was implemented, ensuring credibility and a qualitative result. Throughout the stages ofthe product development process, a product specification was established, before generating concepts and selecting a final candidate which were refined based on the selection of materials and elaborated process plan. Finally, a verification of the requirements was concluded using several methods to prove the performance of the product. The results presents a developed product fulfilling established requirements and includes required documentation for production. Overall, the product is considered to have great potential for customer satisfaction, and to perform well in a final testing according to military standards.
