Research on morphological bionic design based on extensible semiotics and fuzzy comprehensive evaluation

Aiming at the ambiguity problem in the process of morphological extraction and characterization in morphological bionic design, the innovative expression of products is studied from the perspective of extension semiotics. Based on the extensible primitive theory, a morphological bionic design symbol extensible primitive model is constructed, and the feature element symbol extraction and extendable transformation are carried out to obtain an innovative plan for morphological bionic design, and using the fuzzy comprehensive evaluation method selects the optimal plan. Taking the bionic lamp of Lintong pomegranate as an example, the above method is deeply analyzed and verified. The results show that the morphological biomimetic method based on extendable semiotics and fuzzy comprehensive evaluation method has good feasibility, which provides a method reference for product creative design.
