Research on Health Education Plate Design for Elderly Based on QFD and TRIZ

The QFD-TRIZ model was introduced into the product design to address the problems of the elderly coexisting with multiple chronic diseases, poor compliance with health management and unbalanced diets. Firstly, through interviews with elderly users, the needs collected are classified from the physiological and psychological perspectives, then the HOQ tool is used to rank and classify the needs to obtain a matrix of design technology needs indicators, extract the main conflict transformation problems in the matrix into a TRIZ problem model, and use the strategies provided by TRIZ combined with knowledge of healthy diets to provide a basis for the design of health education plate design for the elderly.
