Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If traditional tripod supports are used, then structural stability is achieved, but the number of components increases and assembly complexity increases
Solution Approach 1:
The patent merges multiple separate insulator components into a single integrated composite insulator unit. The vertical insulator and inclined insulators are combined into one monolithic structure with embedded steel wire reinforcement, eliminating the need for separate mounting plates, clamps, and assembly fasteners that would be required for traditional tripod supports.
2Stability of the object's composition
If traditional tripod supports are used, then structural stability is achieved, but assembly time increases
Solution Approach 1:
The steel wire reinforcement structure is pre-formed and embedded within the insulator material during manufacturing. The insulator is produced as a ready-to-install component with all structural elements already in place, eliminating the need for on-site assembly of multiple parts and reducing installation time.
3Reliability
If traditional tripod supports with large dimensions are used, then electrical insulation is maintained, but the gap between contacts increases and current capacity is limited
Solution Approach 1:
The patent changes the geometric parameters of the insulator structure by transitioning from a horizontal tripod configuration to a vertical orientation with inclined stay insulators. This reorientation reduces the horizontal footprint and the gap between contacts while maintaining the necessary electrical insulation distance through the vertical arrangement and composite material properties.
4Ease of manufacture
If fewer components are used, then production cost decreases and assembly simplifies, but structural stability may be compromised
Solution Approach 1:
The patent employs composite materials combining ceramic or polymer insulator material with embedded steel wire reinforcement. This composite construction provides both mechanical strength and electrical insulation in a single integrated component, maintaining structural stability while reducing the total number of parts and lowering production costs compared to traditional metal tripod supports with separate insulators.
