Abstract: In order to solve the problems of weak comfort, low adaptability, cumbersome customization process and lack of design paradigm of existing knee and ankle foot rehabilitation products, an internal and external morphological configuration system and path of knee and ankle foot rehabilitation products based on information graph are proposed to guide the completion of the product scheme that is accurately adapted to patients and suitable for emotion. Firstly, an information model of the configuration system is proposed for the knee-ankle-foot rehabilitation products, and a morphological configuration design system of the knee-ankle-foot rehabilitation products guided by the information graph construction process is formed. Secondly, the morphological configuration requirements of knee ankle and foot rehabilitation products are informatized, and the internal and external configuration ontologies were constructed respectively. Thirdly, the information data is integrated, and the internal and external data of knee and ankle foot rehabilitation products are collected and cleaned through three-dimensional measurement and visual cognition theory and technology, so as to form a parametric index system and morphological configuration library for the internal morphology, and a product semantic database and morphological configuration library for the external morphology. Then, the physical link between the knee-ankle-foot parametric index system and the internal morphological configuration library, the correlation between the product semantic database and the external morphological configuration library is set and the entity link is completed, and the internal and external morphological configuration information of the knee-ankle-foot rehabilitation product is stored and the information graph was constructed by Neo4J. Finally, the informatization of design decision-making is completed, and a design retrieval system for knee, ankle and foot rehabilitation products is built to guide the design of rehabilitation products. Through the study of the configuration method of knee ankle and foot rehabilitation products, the shape and configuration law and perceptual shape configuration orientation are explored, and the precise adaptation of knee and ankle foot rehabilitation product form configuration path based on information graph is formed, which meets the comfort and emotional needs of users, and provides new research ideas for the shape configuration design of knee and ankle foot rehabilitation products.
