Flexible Flat Cable Layout for Opposed Electrode Contacting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection arrangements for flexible flat cables require two separate cables to contact opposing electrical structures from opposite directions, which is inefficient in terms of material and cost, and complicates the production process.
Innovation Solution
A flexible flat cable design with a first connection region connected to one electrical structure and a second connection region connected to the other structure, where the cable is routed out of the composite pane, allowing for single-cable contact from both sides by folding the strip-like section to align the connection regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate flexible flat cables are used to contact opposing electrical structures from opposite directions, then reliable electrical contact is achieved, but material usage increases and production complexity increases
Solution Approach 1:
The patent combines two separate flexible flat cables into a single cable with two connection regions. The first connection region contacts the first electrical structure from the first direction, while the second connection region contacts the second electrical structure from the second direction. This merging reduces material consumption while maintaining the reliability of electrical contact for opposing structures.
Solution Approach 2:
The single flexible flat cable is designed to perform multiple functions: it provides electrical contact for both the first electrical structure and the second electrical structure, replacing what would traditionally require two separate cables. The cable acts as a multi-functional connection element that serves dual purposes in the composite pane assembly.
2Reliability
If two separate flexible flat cables are used to contact opposing electrical structures, then complete electrical connection is achieved, but device complexity increases
Solution Approach 1:
The patent merges two separate cable assembly operations into a single operation. By integrating both connection regions into one flexible flat cable, the production process requires handling and installing only one cable component instead of two, thereby reducing assembly complexity while ensuring complete electrical connection for both structures.
3Loss of substance
If a single flexible flat cable is used to contact both electrical structures, then material usage is reduced, but the cable routing complexity increases
Solution Approach 1:
The flexible flat cable is segmented into distinct functional regions: a first connection region for contacting the first electrical structure and a second connection region for contacting the second electrical structure. This segmentation allows each region to be optimized for its specific connection task while being part of a single integrated cable, managing routing complexity through functional division.
