Most of aesthetic design methods proposed in the field of kansei engineering ask customers to evaluate the same type of existing products as a design target, analyze the relationships between their results and aesthetic features and generate a new design desired by customers. Therefore, customers need to conduct a lot of kansei evaluations for each design and those evaluations become their heavy burden. To reduce customers’ burden, this paper proposes a method for reusing kansei evaluation results for the aesthetic design of different types of products. The basic idea of the proposed method is that the decision rules extracted from one type of product can be applied to others if they have the same aesthetic features. Therefore, once kansei evaluation results of various types of products are sufficiently collected, it becomes possible to design new products without additional kansei evaluation. In the case study, to demonstrate a design flow using the proposed method, low heel pumps and a long wallet were designed based on kansei evaluation results of penny loafers, high heels and sneakers. Low heel pumps are a type of women’s shoes like penny loafers, high heels and sneakers while a long wallet is different from them. The obtained designs were evaluated by subjects to reveal the properties / effectiveness of the proposed method.
