Teenage consumers and adult consumers have different lifestyles and consumption characteristics, and a differentiated design model is needed. To better understand the design needs of young women for autumn and winter outdoor sportswear, the following design requirements analysis will be conducted. Firstly, using the KANO model to collect data from the KANO model questionnaire, organize and classify different types of clothing design requirements; Secondly, due to the inability of the KANO model to quantify the importance of demand factors, a weight analysis of each design demand is conducted using the Analytic Hierarchy Process (AHP), and the scientific and reliable results are ensured through expert scoring and consistency testing. The results show that the design of outdoor clothing for adolescent women should prioritize the functionality of fabrics, followed by adjustable structural design and fashionable color to meet their diverse needs. The comprehensive application of KANO model and analytic hierarchy process in the theoretical research of outdoor clothing design for adolescent women can quickly assist designers in choosing design directions, making the design scheme more scientific and reasonable.
