Research on the Application of Digital Twin Technology in Age-Friendly Design of Multi-Generational Households and Strategies for Mitigating Intergenerational Conflict - A Case Study of a Family in Fengtai District, Beijing

Abstract

With the popularization of multi-generational cohabitation family structures and the acceleration of the aging process in China, the demand for comfortable and age-friendly living environments is becoming increasingly prominent. Traditional design methods struggle to effectively reconcile the differences among multi-generational members in terms of space-use preferences, lifestyle habits, and safety needs. This study takes a typical multi-generational family in Beijing’s Fengtai District as a case study. Through on-site surveys, behavioral observations, and in-depth interviews, it systematically outlines the psychological needs, daily activity flow lines, and behavioral characteristics of different family members, summarizing the usage barriers and potential intergenerational conflicts present in various functional scenarios of the home. Building on this, the research introduces Digital Twin technology to construct a dynamic digital model, enabling real-time mapping and interaction with the physical environment. This method not only optimizes the family’s spatial flow layout and functional configuration, allowing members of all generations to directly participate in the dynamic visualization simulation and evaluation of multiple design proposals, but also generates multi-stage renovation plans based on changes in residents’ physical conditions, ensuring a perfect match between the living environment and the residents. The study aims to explore the application path of Digital Twin technology in the barrier-free environment of multi-generational households, providing innovative strategies and practical references for mitigating intergenerational conflict and building an inclusive human living environment.
