Starting from the dual demands for comfort and safety in the elderly living space

this paper proposes an implementation scheme for the in-depth integration of the smart home-based elderly care system and aging-friendly renovation of residential space. Following the design principles of physical space adaptation and aging-oriented interactive interface

an overall functional framework is constructed

which covers intelligent security

environmental regulation

health monitoring and elderly-friendly kitchen system. Through the practical application of typical scenarios of the smart home-based elderly care system

all-round support is realized from basic safety protection to life quality improvement

which effectively optimizes the elderly's home living experience. This research can provide theoretical support and practical reference for the intelligent aging-friendly renovation of residential spaces for home-based elderly care.
