Design of Intelligent Medicine Box for Visually Impaired People based on QFD and TRIZ Theory

In order to solve the problems that visually impaired people tend to take medicine by mistake and forget to take medicine, by analyzing the emotional and physiological needs of users, an intelligent medicine box design for visually impaired people based on Quality Function Deployment (QFD) and Theory of the Solution of Inventive Problems (TRIZ) theory is proposed. First, through the research on the psychological and physiological characteristics of visually impaired people, the user perception characteristics were obtained; secondly, the QFD theory was used to conduct research on the needs of target users, build a product demand quality house, and obtain the main needs and problems, then use TRIZ theory to analyze and solve problems. By analyzing the middle-aged and elderly people with visual impairment, the psychological and physical resistance of such people to taking medicine can be reduced, and a smart pill box for visually impaired people is designed to help the visually impaired people to take medicine on time and accurately.
