doi:10.3901/JME.2023.11.300

Abstract

Abstract: In the field of hand function rehabilitation product design, the collaborative realization mode of biological functions is used to guide the solution of product functions, so as to improve the applicability of product design and the efficiency of cross domain transformation. Based on the spiral path of bionic design and the need of hand rehabilitation, the functional tree model is established, and the problem is biologized. The Asknature knowledge base is used to search and screen biological prototypes. According to the analogy principle, the biological function system and the technical function system are analyzed, and the similarity calculation is carried out to obtain the effective bionic object, which biological effect is analyzed. Through the analogical model of bio-product system, the mapping relationships of morphology structure, behavior principle and movement environment are obtained. Through the product function solving model, the biological prototype can be imitated and copied on the functional realization level. After the biological prototype is determined based on the functional similarity, the biological effect features are extracted, which can improve the functional structure of hand function rehabilitation product and guide its design. The cross-domain functional combination is realized to help designers quickly realize the design goals in bionic design.

Key words: biological effect, hand function rehabilitation, function innovation, bionic design
