The work aims to use the characteristics and advantages of dynamic patterns to improve the visual effect, break through the limitation of plane, and present pattern contents by more novel, intuitive, and interesting digital means, so as to enhance the attractiveness of excellent traditional Chinese culture to people, and promote the prosperity and development of intangible cultural heritage in the digital era. The relevant theories of analytic hierarchy process were used to analyze the phenological characteristics of the 24 solar terms, the characteristics of agricultural activities and other related cultural factors. The typical cultural genes of the solar terms were extracted and converted into design elements, so as to construct the dynamic pattern design of the 24 solar terms. The analytic hierarchy process and semiotic theory were applied to the design of the dynamic pattern of the 24 solar terms, and the typical factors influencing the dynamic pattern design of the 24 solar terms were determined, successfully completing the innovative design direction and specific scheme of the research. By carrying out innovative research on the design of dynamic patterns of the 24 solar terms with analytic hierarchy process and semiotic theory, the typical factors in the design can be determined clearly and the design definition and direction decisions can be realized, successfully completing the research objectives, and enhancing the new connotation of the 24 solar terms culture.
