Flexible Circuit Cable with Segmented Wire Bundles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional signal transmission cables face issues with electromagnetic interference and spatial constraints, particularly in applications with hinge structures, leading to increased wire costs and reduced design flexibility due to bundling all wires together.
Innovation Solution
The cable is slit into cluster wires forming independent bundles for different signal groups, with bundling members made of insulation, conductive fabric, or electromagnetic shielding materials to separate power, grounding, and signal wires, allowing for reduced electromagnetic interference and flexible layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all signal transmission lines are bundled together for protection and positioning, then mechanical durability and EMI shielding are improved, but electromagnetic interference between signal lines increases
Solution Approach 1:
The cable is divided into multiple independent bundles, each containing specific signal lines or wire groups. This segmentation allows different signal groups to be isolated from each other, reducing electromagnetic interference between them while maintaining the protective bundling structure for mechanical durability.
2Reliability
If all wires of a cable are bundled together and put through a hinge structure, then cable protection is improved, but the space required in the hinge structure increases
Solution Approach 1:
The cable is divided into multiple independent bundles that can be routed separately through the hinge structure. This allows the bundles to pass through narrower spaces individually rather than requiring a large single opening for the entire bundled cable, reducing the volume required in the hinge structure.
3Ease of manufacture
If all signal transmission lines are bundled together, then cable assembly is simplified, but wire length and cost increase
Solution Approach 1:
The cable is divided into multiple independent bundles, each containing specific wire groups that can be optimized for their particular functions. This allows for more efficient routing and reduced wire length compared to a single large bundle, while still maintaining simplified assembly procedures through standardized bundling processes.
4Device complexity
If all signal transmission lines are bundled together in a single bundle, then cable structure is simplified, but the area required on the circuit board increases
Solution Approach 1:
The cable is divided into multiple independent bundles that can be distributed across different areas of the circuit board according to the functional requirements of different signal groups. This allows for more efficient use of circuit board space compared to a single large bundle that would require a集中ized area, while maintaining relatively simple cable structure through standardized bundling.
