Research on Wheelchair Design for the Disabled Elderly Based on QFD/TRIZ

Abstract

Objective This research proposes a wheelchair design method for the elderly with disabilities based on the combination of QFD theory and TRIZ theory to improve the satisfaction of the needs of elderly users and the feasibility of implementing related product technologies. Methods Starting from the needs of disabled elderly people, this research analyzes the shortcomings of QFD theory and TRIZ theory, and builds a framework model that combines TRIZ and QFD theory. Conclusion Through the redesign of the wheelchair, the various problems encountered by the disabled elderly in the process of using the wheelchair are solved, and their needs in the wheelchair are met. At the same time, through the analysis of the design process and results, the QFD/TRIZ integrated model is proposed and verified The feasibility of functional product design that can be applied to disabled elderly people.
