<p>In order to effectively obtain the design requirements and weights of users when wearing one-piece ski suits, and at the same time determine and quantify them into design strategies based on the requirements, so as to effectively improve user satisfaction and enhance user wear experience. This research first constructs a user journey map through user interviews, analyzes the behavioral paths of users when wearing ski suits and sorts out user needs; secondly, creates a Kano five-order two-factor questionnaire to investigate the user’s design needs evaluation of one-piece ski suits, and uses the Kano model to analyze the characteristics of user needs; thirdly, use the AHP hierarchical analysis method to construct a one-piece ski suit design needs analysis model, and proposes a one-piece ski suit design strategy based on calculating the user demand weights at each level, and finally tests the rationality of the method through design cases. The research results show that by establishing a method of obtaining user needs with Kano-AHP, the importance of one-piece ski suit design elements is sorted and quantified, and a design strategy to improve user satisfaction is proposed more scientific and reasonable, providing new methods and ideas for related design research.</p>
