Abstract: In order to design the products that meet consumer emotional demand, the method of product image form design based on fuzzy logic is adopted. The first of all is to ascertain the kansei words and the design elements. Based on this, the relationship between them is built by using fuzzy logic. Through fuzzification, fuzzy rules’ construction, fuzzy reasoning and defuzzification, the fuzzy logic controller is designed, and the simulation model is established by using Matlab. Finally, the validity of the model is verified by testing. This study is carried out combining form design of folding bike, and the results show that this method is valid and feasible.

Key words: industrial design, form design of product image, fuzzy logic, folding bike
