In the context of the personalized and diversified modern wedding transformation, the design of wedding supplies based on aesthetic preferences is of great significance. This study combines the Kano model, entropy theory, and stepwise linear regression to construct a design process for wedding supplies based on aesthetic preferences. Firstly, the design requirements are evaluated based on the Kano model to determine the target for designing products with attractive features. Secondly, entropy theory is applied to obtain the weights of aesthetic preference imagery and the comprehensive evaluation values of aesthetic preferences for each research sample. Then, using stepwise linear regression, the relationship between aesthetic preferences and sample design elements is established to guide design practice. Finally, taking the Chinese character "囍" (symbolizing happiness) as an example, the design schemes are generated to demonstrate the feasibility of the entire research process.
