Abstract [sv]

På uppdrag av företaget Krabat AS har ett produktutvecklingsarbete för att ta fram ett tillbehör till deras rullstol Krabat Sheriff utförts. Syftet med projektet har varit att utveckla ett tillbehör för att öka rullstolens mobilitet i terräng. Målet med processen har varit att ta fram ett underlag för vidareutveckling av ett av- och påmonterbart tillbehör som ska passa Krabat Sheriff. Detta har genomförts genom att ta fram lösningar med hjälp av marknadsanalys, intressentanalys och teoristudier samt visa olika konfigurationer av de framtagna lösningarna för att slutligen presentera koncept. Arbetet har följt Krabats egen produktutvecklingsprocess, P-08, som inkluderar faserna idé, marknadsundersökning, kravspecifikation, koncept, produktspecifikation, detaljkonstruktion och granskning. I idéfasen gjordes en marknadsanalys samt en intressentanalys för att skapa en överblick av vad kunden och marknaden ville ha. Kravspecifikationen bestod av primärbrukarens krav och önskemål. Den fungerade som en checklista som alla koncept gick igenom för att se om de var realiserbara. I konceptfasen skissades och utvärderades samtliga koncept med hjälp av en beslutsmatris. Beslutsmatrisen valde ut två koncept som vidare utvecklades. Dessa två koncept kombinerades till ett som sedan gick vidare till produktspecifikationen. I produktspecifikationen beskrevs det slutgiltiga konceptet, Krabat Revolvers lösningar i detalj. I detaljkonstruktionen beskrevs Revolvers materialval och tillverkningssätt. Slutligen gjordes en granskande överblick av projektet med hjälp av en feleffektanalys som kontinuerligt byggts på under projektets gång. Sammanfattningsvis ses projektet som lyckat då både syfte och mål har uppnåtts; underlag för en produkt som löser huvudproblemet har tagits fram. Det finns även ett dokumenterat intresse för produkten vilket skapar ett nyhetsvärde för samtliga intressenter.

Abstract [en]

On behalf of the company Krabat AS a product development case concerning developing an accessory for making their wheelchair, Krabat Sheriff, more usable in terrain has been done. The purpose has been to produce a material for further developing of a detachable accessory made for the Sheriff. The goal has been to present a proposal of solutions obtained by market analysis, stakeholder analysis and theoretical studies as well as showing the possible solutions, showing their optimal configurations and proposing a final concept. The work has been following Krabat AS product development process, P-08, which included the following phases: idea, market research, specifications of requirement, concept, product specifications, details and review. In the idea phase the problem, cause and goal was formulated. In the market research phase a market analysis as well as a stakeholder analysis was done in order to get an idea of what the customer and the market wanted in the product. The specification of requirements consisted of the demands and requests of the primary stakeholders. It worked like a checklist which every concept had to pass to work as a real product. In the conceptual phase every concept was drawn and evaluated. By help of a decision making matrix two concepts was deemed the best. These two concepts where continued working on finally making it one continuing on to the product specification phase. In the product specification the final concept, Krabat Revolver, was introduced and explained in detail. In the detail phase the way of production, configuration of parts and choice of material was documented. In the last phase the project was reviewed by help of a FMEA-analysis which had been worked on the entire project. In conclusion the project is a success since it both has been able to accomplish the purpose and the goal; documenting a material for a product that clears the main issue. It also exist a documented interest for the product by the stakeholders which make the product newsworthy.
