Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires are accommodated in a housing provided in an arm member to prevent tangling, then wire management is improved, but the conduction path structure becomes complex and assembly becomes difficult
Solution Approach 1:
The patent merges the structural arm members with conduction path functions by making the arm members themselves conductive. This eliminates the need for separate housings to accommodate wires, as the arm structure directly serves as the conduction path, thereby simplifying the overall structure while maintaining reliable power and signal transmission to the actuator.
2Reliability
If a flexible material covers the robot arm to improve safety, then safety is improved, but double insulation is applied to the covered portion which is redundant and increases complexity
Solution Approach 1:
The patent extracts the redundant insulation layer from the design. Since the arm members are already made conductive and serve as conduction paths, the flexible covering material provides sufficient insulation without requiring an additional insulation layer. This eliminates double insulation while maintaining safety, thereby reducing structural complexity.
3Reliability
If additional cables are used for power and control signals, then conduction paths are established, but the structure becomes complex and assembly efficiency decreases
Solution Approach 1:
The patent makes the arm members multi-functional by designing them to serve both as structural support and as conduction paths for power and control signals. This eliminates the need for separate cables, simplifies the conduction path structure, and significantly improves assembly efficiency while ensuring reliable electrical connections to the actuator.
