Rapporten behandlar det kandidatarbete som fem studenter blev tilldelade våren år 2014. Målet med arbetet innefattar utveckling och framtagning av en produkt som underlättar förtöjning av båtar vid exempelvis bojar och bryggor. Detta kandidatarbete resulterade i en produktdesign av en båtshake som underlättar förtöjning och denna uppfyller behov som har identifierats från en marknadsundersökning. Arbetet innefattar analyser av tillverkningsmetoder och material för att finna lämpliga sådana vid framtagning av produkten i fråga. Rapporten redogör även för hur koncept och design har tagits fram med hjälp av diverse konceptgenereringsmetoder. För att testa produktdesignen och dess funktioner tillverkades en prototyp likvärdig med den framtagna designen. Denna testades i sin arbetsmiljö, men även i en simulerad sådan. Därefter gjordes bedömningen att den uppfyller de mål och krav som har satts upp för projektet. / The report discusses the bachelor’s thesis that five students were assigned in the spring of 2014. The goal of this thesis includes the development and production of a product that facilitates the mooring of boats, for example to buoys and piers. This paper covers the work process resulting in a product design of a boat hook that facilitates mooring. This product was designed to meet the customer needs identified during a market survey. The report analyzes the manufacturing methods and materials in order to find appropriate ones for the production of the designed product. The report describes how the concept and design was developed assisted by various concept generation methods. To test the product design and its features a prototype similar to the developed design was produced. This was tested in a realistic working environment, but also in a simulated one. The conclusion was that the prototype met the required customer needs that were put forth throughout the project.
