Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the hollow insulator structure is used for OPGW optoelectrical separation, then insulation between OPGW and tower is achieved, but misoperation may cause steel pipe extension into hollow insulator leading to insulation failure
Solution Approach 1:
The arc-shaped guide structure is pre-installed in the hollow insulator to guide the steel pipe during insertion. This preliminary structural arrangement ensures that the steel pipe follows the correct path and cannot extend into the hollow insulator, preventing insulation failure before it can occur during operation.
Solution Approach 2:
The arc-shaped guide structure acts as an intermediary element between the steel pipe and the hollow insulator. It mediates the insertion process by providing a guided path that physically prevents the steel pipe from entering the hollow insulator, thus protecting the insulation while maintaining operational simplicity.
2Ease of manufacture
If the optoelectrical separation apparatus is modified from OPPC splice box design, then existing design experience is utilized, but construction errors may occur during installation
Solution Approach 1:
The arc-shaped guide structure is pre-installed in the hollow insulator to guide the steel pipe during insertion. This preliminary structural arrangement ensures that the steel pipe follows the correct path and cannot extend into the hollow insulator, preventing insulation failure before it can occur during operation.
Solution Approach 2:
The invention changes the geometric parameter of the insertion path by introducing an arc-shaped guide structure with specific curvature. This parameter change ensures that rigid steel pipes cannot follow the curved path, while flexible optical fibers can, thereby automatically differentiating between correct and incorrect components during installation.
3Reliability
If the cylindrical structure with arc segment is used, then steel pipe insertion is blocked, but only optical fiber can pass through
Solution Approach 1:
The invention applies curvature by designing the guide structure with an arc segment. This curved geometry allows flexible optical fibers to pass through while blocking rigid steel pipes, achieving component differentiation and protection without requiring complex mechanical systems or multiple parts.
Solution Approach 2:
The arc-shaped guide structure utilizes the flexibility difference between optical fibers and steel pipes. The curved path acts as a flexible constraint that accommodates the flexible optical fiber while preventing the rigid steel pipe from passing through, achieving protection through geometric flexibility rather than mechanical complexity.
