Abstract

In response to the lack of psychological considerations in the design of elderly mobility aids in the context of an aging society, the work aims to propose an innovative design method for elderly mobility aids based on QFD/TRIZ theory and study the innovative design of products for the elderly by integrating with future development trends. The Quality Function Deployment (QFD) theory was employed to construct a quality house for elderly mobility aids to identify elderly user needs and translate them into product technical features. Furthermore, the design process integrated the principles of TRIZ theory, including separation, combination, and self-service principles, to implement product design effectively. Based on the foundation of QFD and TRIZ theories, a practical design approach was proposed, resulting in a rational design scheme for elderly mobility aids. The research on innovative design of elderly mobility aids demonstrates that the integration of QFD and TRIZ theories accurately uncovers the physiological and psychological needs of elderly users and effectively translates these needs into specific product designs. The entire process validates the feasibility and reliability of integrating QFD and TRIZ theories in the design of elderly mobility aids.

Key words
