Abstract

The work aims to propose an improved design of the existing sitting rehabilitation training based on the TRIZ theory and emotional design to solve the lack of emotional design in the existing children's seated rehabilitation training chairs. Emotional design was applied to analyze the improvement needs of existing children's seated rehabilitation training chairs at three levels. A functional analysis model based on the TRIZ theory was used to mine problems between product components, causal chain analysis was used to identify the root causes of problems, and improved design solutions were obtained through physical contradictions, technical contradictions, and physical field models. The children's seated rehabilitation training chair improved based on the TRIZ theory changed the position of the handle and increased the coordinated movement function of the lower limb main joints. The color, shape, and human-machine dimensions of the cold product were designed to meet the emotional needs of rehabilitation for children with cerebral palsy, and finally the appearance prototype was completed. The application of the TRIZ theory and emotional design in the improved design of children's seated rehabilitation training chairs makes up for the lack of emotional design in the product, improves the lower limb rehabilitation experience for children with cerebral palsy, and provides design references for related lower limb rehabilitation products for children.
