89700 - A Multi-Domain Knowledge Transfer Method for Conceptual Design Combine With FBS and Knowledge Graph 

Conceptual design is an essential step in product innovative design, a definitive design process and effective solution methods enable the rapid solving of design problems. In the conceptual design process, conceptual design solutions are solved by mapping multi-domain knowledge to design problems. However, such a process exists with multiple mapping paths and weak connections between knowledge. With the further expansion of knowledge engineering, the product design process based on knowledge graph is proved to be beneficial to inspire designers' thinking and stimulate creativity. Therefore, we propose a knowledge transfer method that combines Feature-Behavior-Structure(FBS) and Knowledge Graph(KG) for the conceptual design solution. Based on the FBS model, the authors structure the design process, identifying and evaluating the functions and behaviors that satisfy the design requirements, integrating multi-domain knowledge based on knowledge graph technology, and transferring it to the design process to support the conceptual design to be solved. Finally, the paper verifies the feasibility of the method with the design of a hoisting structure for heavy-duty and high precision movement. The results show that the proposed method is helpful in solving the ideal design solution, reducing the iterative steps, and improving the design efficiency to a certain extent.
