The work aims to further improve such requirements as functional integration and adaptability of the product while maintaining its existing advantages. An innovative design strategy based on ideal solution-conflict method was proposed. The strategy started with the comprehensive analysis of the product system, and then determined the ideal solution to the system. By comparing the ideal solution with current product system, the problems that existed in the system were found out, then the conflicts existing in the system were analyzed, determined and then solved with the conflict resolution principle. Finally, the product system plan for further improvement was determined. The strategy is applied in the innovative design of fore limb structure of hexapod bionic robots, which significantly improves their work efficiency and environmental adaptability. The simulation on walking and explosive handling of the improved hexapod robot is carried out with the kinematics simulation software. The simulation results show that the robot has good mobility performance and execution performance, through which the feasibility of the proposed innovative design strategy can be verified.
