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

Conceptual design as 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. Therefore, we propose a knowledge transfer method that combines Function Behavior Structure (FBS) and Knowledge Graph (KG) for the conceptual design solution. Based on the FBS model, we structure the design process, identify and evaluate the functions and behaviors that satisfy the design requirements, integrate multi-domain knowledge based on knowledge graph technology and transfer it to the design process to support the conceptual design. 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 for solving the ideal design solution, reducing the iterative steps, and improving the design efficiency to a certain extent.
