Flexible Cable Test Opening Cover for Connectivity Checks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flexible cables lack easy verification of electrical connectivity, which is crucial for high-performance digital devices with numerous bends and connections.
Innovation Solution
A flexible cable design featuring a conductor with distinct regions, insulating film with defined openings, and a cover portion that can be opened and closed to expose test openings for verifying electrical connectivity, along with support portions to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insulating film is fully encapsulated without openings, then the cable structure is more compact and protected, but electrical connectivity verification becomes difficult
Solution Approach 1:
The insulating film is segmented with multiple openings (first connection opening, second connection opening, and test opening) that divide the encapsulation into functional zones. This segmentation allows different portions of the conductor to be accessible for different purposes while maintaining overall encapsulation protection.
Solution Approach 2:
The cover portion acts as an intermediary element that can be opened and closed to expose the test opening. This mediator provides controlled access to the conductor for connectivity verification while maintaining the protective encapsulation when closed, resolving the contradiction between verification needs and structural protection.
2Reliability
If connection openings are provided for electrical connection, then connectivity is improved, but the cable becomes more vulnerable to damage
Solution Approach 1:
The cover portion merges multiple functions: it protects the test opening from damage, maintains the encapsulation integrity, and can be opened for connectivity verification. By combining these functions into a single integrated component, the cable gains protection without sacrificing electrical connection capabilities.
Solution Approach 2:
The cover portion is designed as a flexible component that can be opened and closed, providing dynamic protection to the connection openings and test opening. This flexible shell approach allows the cable to maintain durability while enabling access for electrical connection and verification when needed.
3Ease of manufacture
If the cable structure is simplified without cover portions, then manufacturing is easier, but the test opening cannot be protected from damage
Solution Approach 1:
The cover portion is designed to work with standard insulating film materials and can be integrated into existing manufacturing processes. It serves multiple functions simultaneously: protecting the test opening, maintaining encapsulation, and enabling controlled access. This multi-functionality justifies the additional manufacturing step by eliminating the need for separate protection mechanisms.

AI summary
A flexible cable includes: a conductor that includes a first region and a second region disposed opposite to each other along a length direction, and a third region disposed between the first region and the second region; an insulating film that encapsulates the conductor and in which a first connection opening exposing a part of the first region, a second connection opening exposing a part of the second region, and a test opening exposing a part of the third region are defined; and a cover portion that is disposed to be able to be opened and closed on the insulating film to cover the test opening.
