Utveckling av motocrossadel

by Apelstedt, Kristoffer; Dahl, Andreas

Abstract This master’s thesis was carried out in cooperation with Highland group AB in Jonkoping. They are a company that develops and improves already available motocross parts, everything from the engine to hoods. The thesis embodies the development of a new motocross seat. This product will suit both Highlands products and will also be out for sell to other competing companies. The question that was asked by the company was if it would be able to manufacture a seat that quickly and flexibly could adjust in height, which would mean great advantages because several drivers could use the same seat. Another reason why this product is needed is that drivers shouldn’t need several different seats to adjust the riding height though this can separate depending on the terrain that’s being driven. The seats today exist of three different parts: • Frame • Pad • Slipcover Consequently the seat should be able to adjust in height but also exist of as few parts as possible. Today’s seats also don’t have the possibility to adjust the stiffness on the pad but this was only a desirably demand from the company. Under the master’s thesis time the authors has used several different methods to generate ideas and has through them make off with different concepts. The generated ideas have been followed by sieving to decide which concepts that would fill the function best. The master’s thesis result in two concept where chosen because they together would combine their functions and finally create ONE concept. A crap-up was made to test if the function would actually work. The test came out positive though demanded further development. The company thought this was a good idea because it was both simple and fast to adjust and the company is planning to make a prototype because the timeframe was proven to short for the writers to make a one of their own.
