Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat cables lack flexibility and are prone to noise interference due to signal line alignment issues, making them difficult to connect devices that are not aligned linearly, and they have high unit costs and limited bending capabilities.
Innovation Solution
A flat cable design with signal lines divided into groups separated by slits, featuring a binding member with a helical cutting line and a shield to intercept noise, allowing for improved flexibility and noise reduction, and connectors that can align with misaligned devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If signal lines are spread out in a flat cable to reduce noise interference, then noise resistance is improved, but flexibility deteriorates because the cable cannot be bent like wire-type cables
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 slits that extend from the end surface toward the center, allowing the cable to be bent and folded while maintaining signal line integrity and reducing noise interference between adjacent signal lines.
2Adaptability or versatility
If connectors are connected to misaligned devices by folding the flat cable, then adaptability is improved, but noise interference increases due to interference between signal lines
Solution Approach 1:
By segmenting the cable into multiple bundles separated by slits, the cable can be folded at the slit locations without causing signal lines from different bundles to come into close proximity, thereby maintaining connection adaptability while preventing noise interference.
Solution Approach 2:
The slits act as intermediary spaces between bundles of signal lines, providing physical separation that prevents electromagnetic interference when the cable is folded to accommodate misaligned connectors.
3Adaptability or versatility
If various folding specifications are created to connect flat cables to misaligned devices, then adaptability is improved, but device complexity increases due to difficulty in managing multiple specifications
Solution Approach 1:
The segmented structure with slits provides inherent flexibility that allows the cable to be bent and folded in multiple configurations without requiring different cable types, simplifying specification management while maintaining adaptability to various connector positions.
