Shield Cable Tape Layer Structure for Bend-Induced Shield Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shield cables can suffer damage to their shields when bent, due to stress applied from adjacent components.
Innovation Solution
Incorporating first and second tape layers made of paper, non-woven fabric, or resin tape between the shield and other components of the shield cable, which reduces adhesion and allows the shield to move freely, thereby minimizing damage when the cable is bent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shield is directly adjacent to other components (insulator, sheath) without intermediate layers, then the cable structure is simpler, but the shield is damaged when the cable is bent due to stress from adjacent components
Solution Approach 1:
The patent introduces a tape layer made of paper, non-woven fabric, or resin tape as an intermediary between the shield and adjacent components (insulator or sheath). This intermediate layer acts as a buffer that reduces stress transmission to the shield during cable bending, preventing shield damage while maintaining overall cable structure. The tape layer is specifically positioned between the shield and the insulator or sheath, creating a protective interface.
2Reliability
If the shield is tightly constrained by adjacent components, then the cable structure is more stable, but the shield cannot move freely and gets damaged during bending
Solution Approach 1:
The tape layer serves as a mediator that provides both protection and controlled movement. It reduces the constraint force from adjacent components on the shield, allowing the shield to move freely during cable bending without being tightly constrained, thereby preventing shield damage while maintaining adequate structural stability.
Solution Approach 2:
The patent uses a flexible tape layer made of paper, non-woven fabric, or resin tape that can deform with cable bending. This thin film structure allows the shield to move freely during bending while maintaining overall cable integrity, preventing stress concentration and shield damage.
3Reliability
If multiple tape layers are added between the shield and other components, then the shield is better protected from damage, but the cable structure becomes more complex
Solution Approach 1:
The patent employs a single tape layer as an effective intermediary between the shield and adjacent components. This single layer provides sufficient stress reduction and shield protection during cable bending, avoiding the need for multiple layers and thus preventing excessive structural complexity while achieving reliable shield protection.
