目的 在老年人的居家养老生活中，“坐”是他们日常最主要的行为之一，运用AHP、QFD及AD等方法，最终实现居家型适老化座椅的创新设计研究。方法 综合分析了适老化家具市场现状，明确了设计缺口，实地调研挖掘用户需求，运用AHP确定目标用户需求权重，QFD确定设计需求权重，最后使用AD对QFD进行修正，以补充设计方案策略评价中的不足;通过构建相关产品功能概念矩阵，设计一款满足老年人生理及心理需求的居家适老化座椅。结论 明确了用户需求，分析了适老化座椅的设计特征，设计出一款座椅产品;借助适老化功能座椅实际模型，验证AHP、QFD、AD方法的可靠性与安全性，为适老化座椅系列产品设计研究提供了一定的参考依据，为未来开发适老化家具提供了研究思路。

In the elderly's home care life, "sitting" is one of their most important daily behaviors. This study aims to use AHP, QFD and AD methods to finally realize the innovative design of home-type seats for the elderly. The current situation of the age-appropriate furniture market is analyzed comprehensively and the design gaps are clarified. Field research is used to explore user needs, AHP is used to determine the weight of target user needs, QFD is used to determine the weight of design requirements, and finally AD is used to modify QFD to supplement the design strategy evaluation. By constructing a functional concept matrix of related products, a home-friendly seat that meets the physical and psychological needs of the elderly is designed.The user needs are clarified, the design features of age-adaptable seats are analyzed, and a seat product is designed; with the aid of the actual model of functional seats for the elderly, the reliability and safety of AHP, QFD, and AD methods are verified, which provides a certain reference for the design and research of the seat series products for the elderly and research ideas for the future development of furniture for the elderly.
