Taking aging as the background, from the perspective of well-being design, through research on the design of living assistive products for the elderly, this paper promotes the realization of the elderly’s independent participation in social activities to enhance their well-being. Taking the elderly over 60 who can take care of themselves as the target population, the special needs of the elderly by means of interview, on-site observation and other research methods are sort out, and the design methods of life aids for the elderly are summarized in combination with the literature and the analysis of classical design in this paper. Taking the phenomenon of stall economy in the in post-pandemic era as an example, an empirical design of multi-functional trolleys is made. Finally, the design method of life aids for the elderly from the perspective of well-being design is put forward, and the multi-functional trolley scheme for the elderly is designed. Through the design of living assistive products for the elderly, they can be promoted to independently participate in social activities and improve their well-being. The design of living assistive products should be based on the physical, psychological and behavioral characteristics of the elderly, combined with product design rules, and put forward targeted solutions. The design of the trolley for the elderly can help them participate in social life independently in the context of the post-pandemic era.
