Understanding user needs helps to accurately develop food that meets user needs. The work aims to think about the food design of China-Chic Dim Sum, and propose a research method on the food design of China-Chic dim sum based on the Kano-AHP-AD model. The Kano model was used to statistically and analytically analyze the 20 demand indicators of China-Chic dim sum to determine the division of the demand attributes of China-Chic dim sum; The AHP method of weight solving was introduced to clarify the relatively important user needs of different attributes of China-Chic dim sum food design; In order to match the design parameters in the production, the mapping between the functional domain and the design domain of China-Chic dim sum was accomplished based on the principle of axiom of independence of the AD theory, and the matrix was used to to determine the design rationality and optimal solution step by step. The seven important user needs of China-Chic dim sum were identified through weight solving, and the design parameters that China-Chic dim sum should have to satisfy the user needs were derived. And the food design innovation path of China-Chic dim sum was proposed. In conclusion, the design method quantifies subjective concepts into specific values through the combination of qualitative and quantitative, which provides ideas for the food design of China-Chic dim sum. The conclusion has the advantages of intuitive accuracy and scientific rationality, which can provide a reliable reference and scientific theoretical support for the subsequent development of China-Chic dim sum.
