Abstract: In order to improve the users’ satisfaction and the market competitiveness of the product, a product design method is proposed based on Fuzzy-Kano model and TOPSIS. Firstly, after collecting different needs of users on different aspects of products, use Fuzzy-Kano model to categorize users’ needs: Essential Quality, Unary Quality, and Charm Quality. Secondly, take the Essential Quality and the Unary Quality as the main body, use TOPSIS to determine the importance rank of Charm Qualities and filtrate to get reasonable solution and plan for product design. Finally, apply the method to the design of the intelligent lawn mower, to verify its feasibility, providing new inspiration to other similar projects.

Key words: product design, Fuzzy-Kano model, TOPSIS, users&rsquo, satisfaction, intelligent mower
