To improve users' satisfaction with products and enhance the efficiency of enterprises in making reasonable decisions in the scheme evaluation stage, the work aims to introduce the concept of affordance into the experience analysis stage of kitchen appliances and quantitatively assess the experience affordance of kitchen appliances and present a product experience design evaluation method based on the Kano model and the comprehensive assignment method. The user's touch-points in use of kitchen appliance were obtained through in-door research and other methods and the experience design elements were extracted and summarized across five categories of functional affordance, sensory affordance, physical affordance, cognitive affordance and emotional affordance. Secondly, with the help of the fuzzy Kano model, the evaluation indicators of design elements were quantitatively processed, screened and extracted, and the AHP (analytic hierarchy process) was used to solve the subjective weight of each design indicator and the entropy weight method was utilized to solve the objective weight, and then based on the principle of minimum discriminant information calculation of the combination of the weights, the evaluation indicator system of kitchen appliance experience affordance was obtained. Finally, the quality of the evaluation method was validated through user testing and experience evaluations of two cooking machines. This study contributes to the development of a product experience design evaluation method grounded in affordance, demonstrating its feasibility and effectiveness and providing valuable insights for evaluating and improving similar product design solutions.
