Human-Centered Generative AI Framework in Intelligent Construction: A Case Study on Furniture Manufacturing Design

This study introduces a human-centered Generative Artificial Intelligence (GAI) design approach, emphasizing its application in the field of intelligent architecture, with a particular focus on furniture manufacturing design as a case study. This method integrated stable diffusion technology and leverages optimization algorithms to create designs that not only meet structural requirements but also accurately reflect human preferences. Initiated by user-generated 2D sketches, implicit features were captured through technologies such as stable diffusion, resulting in designs that align with the user's unique style. The outputted designs underwent topological optimization to enhance material performance and structural stability. Subsequently, modifications and production were seamlessly executed through the robotic arms. The results demonstrated that the proposed method effectively provides users with a diverse range of stylistic designs, allowing for easy modifications based on text prompts and manuscripts. This study contributed to optimizing the architectural design workflow and providing a structured solution for handling AI-generated outputs.
