Design of Elderly Assisted Wheelchair Based on KJ-Technique and Analytic Hierarchy Process (AHP)

Abstract

With the aging problem becoming more and more serious today, the design and research of age-appropriate products has gradually become a hot topic. With the advent of the aging society, the elderly have more and more say in the whole social market. Aging life, aging interaction, community for the elderly and other social hotspots have emerged. The aging travel problem is a very important part of it. In the past, most wheelchairs commonly used by the elderly were driven by manpower, and the circulation time of power-assisted wheelchairs in the market is relatively short. Therefore, most of the power-assisted wheelchairs in the market now have problems such as unreasonable structure, not suitable for most elderly people, and rigid appearance. In addition to the problems in the shape and structure, the elderly also have some obstacles in the interactive learning of wheelchairs, so it is necessary to pay more attention to the interface and operation mode of wheelchairs. In order to help the elderly design an ergonomic model and effectively solve the difficult problems in their travel process, this paper, from the perspective of the elderly and designers, understands their real views and needs on the power wheelchair, and then summarizes and classifies these needs through scientific methods and transforms them into design entities.
