Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an insulating rod made of insulating material is mounted on the mechanical arm, then the safety of the worker is protected, but the rigidity is poor causing the maintenance tool to shake and reducing maintenance accuracy
Solution Approach 1:
The mechanical arm system is segmented into multiple components: the mechanical arm itself, the insulating rod, and the connection plate with mounting members. This segmentation allows each component to perform its specific function - the mechanical arm provides positioning capability while the insulating rod ensures safety isolation, resolving the contradiction between safety and precision by distributing functions across separate elements.
Solution Approach 2:
The connection plate acts as an intermediary component between the mechanical arm and the insulating rod. It provides a stable mounting platform with multiple mounting members that can securely attach to the insulating rod, thereby improving the overall stability and reducing tool shaking while maintaining the safety function of the insulating material.
2Device complexity
If the connection position between the mechanical arm and insulating rod is fixed, then the structure is simple, but the flexibility and adaptability for different maintenance tasks are reduced
Solution Approach 1:
The connection system is designed with dynamic characteristics through the movable connection between the mounting members and the insulating rod. The mounting members can move along the insulating rod to adjust connection positions, transforming a static fixed connection into a dynamic adjustable connection that adapts to different maintenance requirements while maintaining structural simplicity.
Solution Approach 2:
The connection plate with multiple mounting members provides universal adaptability for different maintenance tools and tasks. The mounting members can be positioned at different locations on the insulating rod, allowing the same mechanical arm structure to perform various maintenance operations on different high-voltage electrical devices, thereby achieving multi-functionality without increasing overall structural complexity.
