Abstract

Most companies in modern society redesign to create new products. Redesign can improve product quality and shorten cycle time, but most redesign product innovations only modify a relevant reference element of the product, ignoring opportunities for redesign innovation brought about by factors affecting customer personality. This research introduces a product innovation redesign method based on kansei engineering and customer personality types. Based on customer personality types, three research goals were proposed. Based on the results of the analysis, a linear quantitative model was established for each personality type to explore the relationship between the customer’s emotional experience and the elements of product redesign. From these models, design support information is generated to assist product designers in redesigning innovations.
