Flat Cable Segmentation for Flexibility and Noise Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat-type cables lack flexibility and are prone to noise interference due to signal line alignment issues, while wire-type cables are expensive and susceptible to defective connections.
Innovation Solution
A flat cable design with signal lines divided into groups separated by slits and connected with a binding member, featuring a tubular shape and helical cutting line, along with a mesh-patterned sheath and noise-intercepting shield, allows for improved flexibility and noise reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flat-type cable is used to reduce cost and noise interference, then unit cost and noise resistance are improved, but flexibility deteriorates
Solution Approach 1:
The flat cable is divided into multiple bundles, with each bundle containing a group of signal lines. These bundles are separated by spaced sections rather than being tightly bound together, allowing the cable to be flexible while maintaining noise resistance through the separated structure.
Solution Approach 2:
The cable employs a flexible binding structure that allows the bundles to move relative to each other while maintaining connection. The spaced sections between bundles provide flexibility similar to wire-type cables while maintaining the flat cable's cost and noise resistance advantages.
2Ease of operation
If signal lines are tied together in a wire-type cable for flexibility, then ease of operation is improved, but noise interference and connection defects increase
Solution Approach 1:
Instead of tying all signal lines together as in conventional wire-type cables, the invention segments the signal lines into separate bundles with spaced sections between them. This segmentation reduces electromagnetic interference between adjacent signal lines while preserving the cable's flexibility through the bundled structure.
3Reliability
If flat cable signal lines are spread out to reduce noise, then noise resistance is improved, but flexibility and ease of connection deteriorate
Solution Approach 1:
The signal lines are organized into bundles with spaced sections between them, combining the noise resistance benefits of spread-out lines with the flexibility benefits of bundled structures. The spaced sections allow bundles to move independently while maintaining overall cable flexibility.
