Folded Flexible Flat Cable for Opposing 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 process of contacting electro-optical functional elements in composite panes.
Innovation Solution
A flexible flat cable with a composite disk and two electrically conductive structures, where the cable has a first connection area connected to one structure and a second connection area connected to the other, allowing for simultaneous electrical contacting of opposing structures using a single cable by folding the strip-shaped section to face the first connection area, eliminating the need for two separate cables.
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 electrical contacting is achieved, but material cost and device complexity increase
Solution Approach 1:
The patent combines two separate flexible flat cables into a single cable by integrating a second connection area on the same cable body. This single cable now performs the function of both original cables, contacting both opposing electrical structures from opposite directions, thereby reducing material cost and device complexity while maintaining reliable electrical contacting
Solution Approach 2:
The single flexible flat cable is designed with multi-functionality, where one cable serves dual purposes: the first connection area contacts one electrical structure while the second connection area contacts the opposing electrical structure. This universal design eliminates the need for separate specialized cables for each contact point
2Reliability
If two separate flexible flat cables are used to contact opposing electrical structures, then electrical contacting is achieved, but material consumption increases
Solution Approach 1:
The patent merges the functionality of two separate cables into one unified cable structure. By integrating both connection areas onto a single flexible flat cable, the total material consumption is reduced while still achieving reliable electrical contacting of both opposing structures
3Ease of manufacture
If a single flexible flat cable is used with connection areas on the same side, then manufacturing is simplified, but contacting opposing structures from opposite directions becomes difficult
Solution Approach 1:
The patent extends the cable structure into another spatial dimension by adding a second connection area that faces the opposite direction. This dimensional extension allows the single cable to reach and contact opposing electrical structures from opposite directions, maintaining manufacturing simplicity while achieving full adapting capability
