Abstract

To address the problems that the current design of aging-adaptable wearable lower limb walking assistance products lacks support from actual demands and is difficult to accurately match the core demands of elderly users, combined with the urgent needs of the elderly group for wearable walking assistance products under the background of population aging, the work aims to study the design of aging-adaptable wearable lower limb walking assistance products. With elderly users of walking assistance products as the research objects, statistical methods were adopted to integrate EFA, CFA and SEM progressively. The four antecedent dimensions and one outcome dimension of aging-adaptable wearable lower limb walking assistance product design were extracted and verified, and the influence degree of each antecedent dimension on user satisfaction was determined. According to the weight priority, the design scheme of aging-adaptable wearable lower limb walking assistance products was completed, including core functions such as walking assistance. The materials, dimensions and human-computer adaptation details were optimized to realize the accurate matching between the design scheme and the demands of elderly users. The EFA-CFA-SEM method can provide scientific quantitative support for the design of aging-adaptable wearable lower limb walking assistance products and effectively improve the pertinence and rationality of product design. The research results can provide reference for the precise design of similar aging-adaptable products.
