The work aims to combine ergonomic theory and methods to study the issues related to the field of elderly mobility scooters and services, so as to create more age-friendly products and provide innovative solutions with a focus on shared services. Based on the systematic consideration of human-machine relations, dimensions, interactions, and services of elderly mobility products, the physiological, psychological and behavioral characteristics of the elderly were explored. Through the AHP and QFD methods, the demands of the elderly and service management were empirically studied and integrated into product and service design. The research results indicate that through the analysis of human-machine demands, the shared service models are applied to the travel mode of the elderly community environment, regulating the driving behaviors of the elderly, reducing the safety hazards of driving and comprehensively improving the user experience, providing new ways for solving the problem of short-distance travel of the elderly. By using the AHP-QFD method, the different levels of demands are transformed into functions, the scientific and accurate research of product demands is improved, and the research methods are provided for complex multi-type product demands.
