“In the context of parametric design based on visual programming, this study explores an innovative approach combining digitization and localization. It applies a two-way progressive structural topology optimization algorithm to conduct research on innovative urban furniture design in the Wuyi Overseas Chinese Hometown. It utilizes digital media to connect with local cultural characteristics, taking the “qilou” architectural style in the Wuyi Overseas Chinese Hometown as a design prototype. Through the algorithm, the study progresses through initial design preparations, formative design, topology optimization design, and post-processing manufacturing to create urban furniture that embodies both local characteristics and aesthetically pleasing forms, as well as structurally sound and digitally ecological elements. It employs the power of design to address local and regional real-world issues, enhancing the daily experiences of local residents and out-of-town visitors. The design practice validates an innovative design pattern that combines parametric design with local cultural features, providing a novel generative tool and strategy for contemporary innovative furniture design in the Wuyi Overseas Chinese Hometown. Furthermore, it serves as a reference for applying this algorithmic model in other domains.”
