Abstract [en]

In this project a product development has been made of a spinnaker pole end fitting. The project has been made in cooperation with Seldén Mast AB; a company that is manufacturing sailing rigs and that is located in Gothenburg.

 

The project has been following a design process that is inspired from Archer’s three-phase model, which consists of an analytical part, a creative part and an executive part. The project started with an extensive pre-study that contained a market analysis of existing fittings today and interviews with users. After the pre-study the concept generation started with a Brainstorming session and then continued with more structured methods as the Idea generator and Contrast thinking. The methods resulted in three different concepts that were presented for Seldén. These concepts were then made as CAD-models as well.

 

The concept selection started with a questionnaire that was sent out to the user-group where the three different concepts were presented. Next selection method was The Weighted Objective Method. It was the same concept that was chosen in both methods and after some discussions with Seldén a final decision could be made.

 

The project resulted in a fitting that has a softer, rounder shape and a more simple design than the fittings Seldén are using today. The new concept also had a more effective tripp trigger-solution and a design that will release the rope in a more simple way. On the back of the fitting a shock-absorber was placed in the shape of a rubber-plate.

Abstract [sv]

I det här projektet har en produktutveckling gjorts av ett ändbeslag för spinnakerbom. Projektet har utförts i samarbete med Seldén Mast AB; ett företag som tillvekar segelriggar och som ligger beläget i Göteborg.

 

Projektet har följt en designprocess som är inspirerad från Archers tre-fas princip och består av en analytisk del, en kreativ del och en verkställande del. Projektet inleddes med en omfattande förstudie inom spinnakersegling som innehöll en marknadsanalys av befintliga beslag på marknaden idag, intervjuer med användare samt undersökning av liknande mekaniska lösningar. Efter förstudien påbörjades en konceptgenerering med en Brainstorming-sittning, processen övergick därefter i mer strukturerade metoder som Idégeneratorn och Ytterlighetstänkande. Metoderna resulterade i tre stycken olika koncept som presenterades för Seldén. Dessa koncept ritades sedan upp som CAD-modeller.

 

Konceptvalet påbörjades med en enkät som skickades ut till användarna där de tre olika koncepten presenterades. Nästa konceptvalsmetod som användes var The Weighted Objective Method. Det var samma koncept som gick vidare i båda metoderna och efter diskussion med Seldén kunde ett slutgiltigt beslut fattas.

 

Projektet resulterade i ett beslag som har en mjukare, rundare form och mer avskalad design än de beslag Seldén använder idag. Det nya konceptet hade även en effektivare tripptrigger-lösning samt en design som kan gör att tampen lättare kan släppas fri. På beslagets baksida lades det till en stötdämpare i form av en gummiplatta.
