Norstedt, Rickard January 2013 (has links)
This report covers a product development project conducted as Bachelor of Science thesis forthe Innovation & design engineer program at Karlstad University.The assignment was supplied by MMB Consulting, Kristinehamn. The purpose of this projectwas to find an alternative way of shaping wire-net insulation mats. This insulation product isused for fire and thermal insulation of technical installations. The insulation consists of stoneor glass wool with a sewn on steel wire netting on the out facing side. This netting has thepurpose to enable fastening to e.g. ventilation ducts and to provide bounding of joints. Thiswire netting makes regular methods for fitting stone or glass wool non applicable. Theexisting method for shaping wire-net insulation has flaws due to not being designed for thisapplication. These flaws include poor ergonomics, efficiency and low result quality.The objectives with this project is to find a new method that makes fitting of wire-netinsulation more efficient and safer for the user regarding personal safety and ergonomics.The work has been conducted according to the methods of the industrial product developmentprocess and the design methodology.The project resulted in a motor driven tool for shaping wire-net insulation that according to atheoretical foundation has proven to be more user adapted through being designed for goodergonomics and by offering a simpler handling. This solution is also considered to be moreefficient and to give better results than the present solution. Some correlation betweenreductions in energy losses from technical installations and the new method is detectable.

Designstudie CamCoil : Inkåpning av haspelsystem / Redesign CamCoil : Housing for reeling system

Björkdahl, Mikael January 2013 (has links)
Arbetet har utförts i kursen Examensarbete för högskoleingenjörsprogrammet i Innovations-teknik och design (MSGC12) vid Karlstads universitet. Handledare har varit universitetsadjunkt Lennart Wihk och examinator professor Leo de Vin. Uppdraget har bestått i att genomföra en designstudie på CamCoil, ett haspelsystem inom främst tillverkande industrin. Anledningen till detta är att uppdragsgivaren, Camatec Industriteknik AB, vill att produkten ska göras mer konkurrenskraftig och öka chanserna att kunna sälja maskinen utanför Sveriges gränser. Målet är att skapa en varumärkessignifikativ konceptlösning som är kompatibel med haspelsystemets många olika utföranden. Handledare hos uppdragsgivaren har varit Mikael Hallenborg. Studien är utförd enligt produktutvecklingsprocessen. Genomförandefasen består av en inledande funktionsanalys, intervjuer med kunder och produktspecialister samt en undersökning kring maskindirektivet för möjligheten att CE-märka kåpan som säkerhetsdetalj. Även studier inom ämnet Kansei Engineering har genomförts, för att undersöka maskinens och slutkonceptets semantiska korrelationer. Resultatet mynnade efter idégenereringen ut i en gedigen konceptbank enligt uppdragsgivarens förfrågan. Ett av förslagen vidareutvecklades genom en layoutkonstruktionsfas. Detta koncept formades för att passa in på haspelsystemet i olika utföranden. Projektet ledde till ett konkluderande koncept som svarar mot problemformuleringen: ”Hur ska en kåpa utformas för att berätta om det egna varumärket, samt göra arbetsmiljön säkrare för en operatör utan att begränsa haspelsystemets funktioner?”. Slutprodukten är kompatibel med olika optionskonfigurationer och utvecklat för att bibehålla en hög underhållsvänlighet. Stort fokus lades på att definiera en tydlig produktprofil för att differentiera problemägarens haspel. / The project has been carried out as a bachelor thesis in the Innovation and Design Engineering Programme at Karlstad University. For this project, Lennart Wihk has been the supervisor and Professor Leo de Vin acted as examiner. The task has been to conduct a design study on CamCoil, a reeling system for strip steel in the manufacturing industry. The reason for this is that the principal, Camatec Industriteknik AB, would like this machine to be made more competitive in the european market. The goal is to create a unique and brand specific concept solution compatible with the many different options of the reeling system. Mikael Hallenborg acted as supervisor from the client. The study has been conducted on the product development process. The implementation phase consists of an initial functional analysis, interviews with customers and product specialists, an investigation into the Machinery Directive for the opportunity to CE mark the housing as a security feature. The concept is also studied on the semantic correlations between CamCoil and the housing. The result culminated into a solid concept database as the client requested. One of the proposals was selected for further development. The conclusion of the project resulted in a concept that responds to the question: "How should a housing be designed to tell of its brand, and make the work environment safer for an operator without limiting the reel systems features? “. This resulted in a saftey feature compatible with different configurations of the machine and with a major focus on defining the product profile.

Gustafsson, Adam, Persson, Thomas January 2018 (has links)
This report describes a Bachelor thesis executed at Jönköping University in Mechanical engineering, specialized in product development and design by Adam Gustafsson and Thomas Persson. The thesis was made during the spring of 2018 and was the final assignment before graduation. Unadvised aluminum cans that are unsealed run risk for bees and wasps to intrude the can. This may have devastating consequences, not least for people with allergy to stings of bees and wasps. Therefore, a need was determined of a product that prevents stings to mouth and pharynx when it comes to drinking from a can. An assignment from Axelent Engineering became the groundwork of this report. The goal of was to generate suggestions of concepts with a safety lid that would eliminate risks from unsealed cans, minimize spill and preserve the characteristics of the drink. From perspective of the client demands and the issues described in the report a result could be presented. Highest priority was the development of the product but desirable was also to implement research of the market, material selection and sales preparations. Based on the theories and methods presented in the thesis two suggested concepts could be screened, which later was weighted to become one final concept. All concepts were compared with starting point from the requirements which revealed the final concept. The result was a compact safety lid that was the best alternative and met the requirements for manufacturing, function clarity and selected target group. The thesis contributed to increased knowledge in the field and gave a clear picture of how the product development process could be. The assignment resulted in a functional prototype that lays the foundation to continue develop into a finished product. The final product aim to increase the comfort and awareness among the consumer.

Friberg, Caroline, Björkell, Mattias January 2010 (has links)
<p>The high level of competition and the rapidly growing technology development has created new challenges for today's businesses where they are forced to deliver more customized products at a lower price and a shorter time period. This places high demands on the companies' ability to design and develop better products in a more efficient way. In addition to developing products, the design process focuses on securing long-term success for the company by developing nourishing skills. However, to achieve an effective design process the companies must improve their ability to plan as well as use their knowledge base in a more efficient manner. Toyota's product development system is a critical component for companies to address challenges that they’re facing and offers a great potential to create significant competitive advantages.

Risktagande vid tidiga beslut i produktutvecklingsprocessen : En jämförelse mellan kvinnor och män

AHLSTRAND, FELICIA, GRANATH, ISABELLE January 2018 (has links)
Produktutveckling anses vara en riskfylld bransch där det dagligen fattas beslut på begränsad information. Skillnader i individers riskvillighet kan därav vara av stor betydelse för de beslut som fattas. Forskning påvisar skillnader i riskvillighet mellan könen vilket har väckt intresse för att undersöka om skillnaderna framträder i denna riskfyllda bransch. I detta arbete har en studie utförts för att undersöka individens riskhantering vid tidiga beslut i produktutvecklingsprocessen. Studien innefattar även en jämförelse mellan kvinnor och mäns riskvillighet. Inledningsvis utfördes en litteraturstudie för grundläggande förståelse om olika teorier som berör risker, dess konsekvenser och genus kopplat till riskhantering. För djupare kunskap inom ämnet kompletterades litteraturstudien med en förstudie. Denna bestod av intervjuer med tre forskare inom riskhantering, projektpsykologi och genus där risker och riskhantering diskuterades utifrån de olika forskningsperspektiven. Vidare utfördes en kvalitativ undersökning bestående av intervjuer med anställda inom produktutvecklingsbranschen. Dessa syftade till att undersöka hur risker definieras inom produktutveckling samt hur individer förhåller sig till riskfyllda beslut. Vidare användes resultatet från den kvalitativa undersökningen för analys mot litteraturen och förstudien samt för att jämföra riskvillighet mellan kvinnor och män. Denna studie visade på att risker inom produktutveckling definieras som alla faktorer som kan påverka tid, kostnad och kvalitet i ett projekt. Hur man förhåller sig till dessa risker skiljer sig mellan individer och studien påvisar även att det finns skillnader i riskbenägenhet mellan kvinnor och män.

Utformning av företagsentré som speglar Autofrics kompetens och värden / Design of a factory entrance that shows Autofric's competence and values

Henriksson, Jessica January 2018 (has links)
Denna rapport beskriver ett examensarbete som utförts för högskoleingenjörsprogrammet i innovationsteknik och design, vid Karlstads universitet. Projektet har handlat om att ta fram ett förslag på en entré till ett industriföretag. Företaget är Autofric AB i Hagfors, som tillverkar spiraler och skruvtransportörer. De har tidigare haft ett tak utanför dörren som de var tvungna att riva ner. Entrén ska spegla företaget och inge kvalitet, företaget ville också kunna tillverka den själva, i så stor utsträckning som möjligt. Under projektet har därför olika förslag på att använda spiraler i entrén tagits fram. Fokus har i detta projekt lagts på utformning av ett skal som kommer att utgöra gestalten. Företaget har själva tagit på sig att utforma bärande konstruktion. Entrén har undersökts med avseende på semantik, vissa lagar för byggnation och lite handplockad teori kring formgivning. Det är ett projekt som har följt produktutvecklingsprocessen och som utnyttjat styrkan av modeller som visuellt hjälpmedel. Med hjälp av en samling kartongskisser, som växte sig större och större under projektet, en hel del goda råd från en arkitekt och företagets egna synpunkter kunde ett förslag som uppfyller önskemålen och svarar på frågeställningen tas fram. Det resulterade i ett halvmåneformat tak som vilar på två pelare. Pelarnas tvärsnitt är hämtat från maskinerna som företaget tillverkar. En upplyst logga finns integrerad i takets framsida. Entrén kan tillverkas till största delen i material och med maskiner som finns tillgängliga hos företaget. / This report describes a Project for Degree of Bachelor of Science in Innovation and Design Engineering, performed at Karlstad´s university. The purpose of the project has been to come up with a proposal of an entrance for an industrial enterprise. The company is Autofric AB in Hagfors, which produces spirals and spiral conveyers. They used to have a canopy which had to be taken down. The entrance should show the spirit of the company and express quality, and the company also want to fabricate it with their own machines and materials as far as it is possible. Because of this, several examples of how to use the spirals in the entrance has been developed during this project. The focus in this project has been on the design of a shell which will become the gestalt. The company will take care of construction for strength. The entrance has been analyzed considering semantics, some laws for construction and some theory of design. The project has followed the product development process and it has taken advantage of the strength of models as a visual tool. A collection of cardboard sketches, that grew bigger and bigger during the project, many good advices from an architect and the company´s opinions led to a proposal that fulfills the requirements and requests and gives a solution to the problem. It resulted in a canopy, shaped as a half moon, resting on two pillars. The cross section of the pillars is inspired by some of the machines the company manufactures. An illuminated logotype is integrated in the frontage of the canopy. The entrance can be manufactured mainly by the machines and materials available at the company.

Hellström, Linnea, Bachtay, Alexandra January 2020 (has links)
Rapporten behandlar ett examensarbete inom Produktutveckling och Design vid Tekniska Högskolan på Jönköpings University 2020. Examensarbetet utfördes på uppdrag av Globe Group som avslutande del av utbildningen Maskinteknik. Arbetet har utförts av Alexandra Bachtay och Linnea Hellström. Arbetet bestod av att ta fram ett koncept på ett optimerat batteribälte hos produktsortimentet för Cramer. Globe Group har tre olika märken, där Cramers produkter är anpassad till professionella användare inom trädgårdsverktyg. Företaget utvecklar batteridrivna trädgårdsredskap. Därmed använder de sig av batteribälte i deras produktserie. I denna ser dem en del problem och därför har Globe Group utformat ett examensarbete med fokus på produktutveckling och konstruktion. Till en början söktes det efter en tydligare bild av användaren och produkten, därmed utfördes förstudier. Med hjälp av de som framkom under förstudien skapades två kravspecifikationer och funktionsanalyser för att kunna få ett bättre perspektiv på alla de olika delarna i produkten. Under skapandet av olika koncept delades det upp i tre områden, midjebälte, batterihållare samt infästning. När endast varsitt koncept kvarstod sammanställdes resultaten. Arbetet inriktas mot att skapa ett stabilare batteribälte med användarvänligheten i fokus. Resultatet av arbetet var ett nytt koncept på hur Cramer kan utforma sitt batteribälte för att tillgodose kundens behov. / The report deals with a bachelor's degree project in Product Development and Design at Jönköping University 2020. The thesis was carried out on behalf of Globe Group as the concluding part of the Mechanical Engineering program. The work was executed by Alexandra Bachtay and Linnea Hellström. The work consisted of developing a concept on an optimized battery belt in the product assortment for Cramer. Globe Group has three different brands, where Cramer's products are adapted to the professional gardener. The company develops garden tools driven by battery. Therefore they are having a battery belt in their product series. In this product they are seeing some problems and therefore Globe Group has designed this project focusing on product development and construction. Initially, a clearer picture of the user and the product was sought, thus feasibility studies were performed. With the help of those that emerged during the preliminary study, two requirements specifications and functional analyses were created in order to get a better perspective on all the different parts of the product. During the creation of different concepts, it was divided into three areas, waist belt, battery holder and attachment between the holder and belt. When only each area had one remaining concept, the results were later compiled into one final product. The work was focused on creating a more stable battery belt with user-friendliness in focus. The result of the work was a new concept on how Cramer can design its battery belt to meet customer needs.
