Produktkoncept: lekhjälm i vintermiljö : ett nytt produktsortiment

Sammanfattning: A protection helmet for young people (3-7 years) in winter environment has been developed in this thesis. The result is a concept proposal for development at STIGA Sports AB in Eskilstuna. This thesis work has been performed during 20 weeks, for a Master of Science in Product and Process development at Mälardalen University Eskilstuna Sweden in September 2009 to January 2010. The helmet is shown as a CAD model with detailed solutions to the outer shell, interior and adjustability (in sizes 50-56 cm) which are the three focused areas in the development. Also a physical model in scale 1:1 has been developed and is shown in this thesis work. To achieve the best result possible the process started with an analysis of the market and the product. All decisions during the development process were made according to European Standard SS EN 1080 Impact protection helmets for young people, which are the requirements necessary for market interest, security and to be CE approved. In the product development process scientific methods have been used to guarantee quality. A function analysis and a product specification formed the basis of the QFD tool, which measured the concept in relation to the requirements and existing products on the market. The analysis of current competitors on the market combined with a SWOT analysis showed that there is potential for STIGA Sports AB to develop a play helmet. That since there is only one direct competitor on the market today. Due to the fact that they do not have their own product development department it is, in a safety perspective, important for STIGA Sports AB to keep a continuous contact with the production. It will guarantee the product’s quality and meet all the requirements of SS EN 1080. A product decomposition was performed to understand the construction of a helmet. Eight developed concepts led, through an evaluation of three concepts with the highest ranking score, to one final combined concept. The concept consists of a two-piece outer shell for the ability to adjust size and a three-piece interior to ensure comfort and safety regarding the essential parts of the head (forehead, rear, sides, temples and crown of the head). The shape and color have been chosen with the intention to appeal the user (children) and at the same time provide a feeling of safety to the purchaser (adults). Stiga Sports AB current product range and design profile has influenced the design throughout the project.
