Folding Display Panel Cable Routing and Tension Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-format displays with modular components are time-consuming to set up due to the need for individual connection of power and data cables, especially as resolution increases and pixel spacing decreases, making mechanical alignment and cable accommodation challenging.
Innovation Solution
The implementation of a folding display panel apparatus with a hinge mechanism that allows panels to fan-fold while maintaining electrical connections, using fixed-length cable sections with slack for data and power wires, and a movable member to accommodate bends in the cables, ensuring uniform tension and preventing cable binding during folding and unfolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If modular display panels are used for large-format displays, then the display can be moved and set up, but the setup time becomes excessively long due to individual cable connections
Solution Approach 1:
The patent combines multiple cables (power and data) into a single integrated cable assembly that connects adjacent display panels. This merging eliminates the need for separate individual connections, allowing all cables to be connected simultaneously as a single unit, thereby dramatically reducing setup time while maintaining all necessary electrical connections.
2Manufacturing precision
If display resolution is increased, then image quality improves, but pixel spacing decreases making cable accommodation difficult
Solution Approach 1:
The patent moves cable routing from the horizontal plane (between pixels) to the vertical dimension (along the edges and rear of panels). By routing cables along the perimeter edges and using vertical space behind panels, the design accommodates high-resolution displays with minimal pixel spacing while maintaining proper cable routing and connections.
Solution Approach 2:
The patent introduces cable management components such as cable channels, grommets, and routing structures that act as intermediaries between the display panels and cables. These intermediary elements guide and protect cables through tight spaces, enabling proper cable accommodation in high-resolution displays where direct cable placement would be impossible.
3Volume of moving object
If panels are folded for storage, then space efficiency improves, but cables may become tangled or damaged
Solution Approach 1:
The patent uses flexible cable assemblies with sufficient slack and movement capacity that can bend and flex during panel folding without becoming tangled or damaged. The cables are designed with appropriate flexibility and length to accommodate the folding motion while maintaining electrical connections, allowing compact storage without compromising cable integrity.
Solution Approach 2:
The patent creates a dynamic cable system that adapts its configuration during folding operations. The cables have built-in slack and movement capacity that allows them to dynamically adjust their position and shape as panels fold, preventing tangling and damage while enabling compact storage configurations.

AI summary
Folding display panels for large-format displays. In an example, the folding display panels are electrically connected by a power cable and a data cable that respectively include a data wire and power wire, and each cable includes a fixed-length section attached at one end to a movable member. When folding adjacent display panels face-to-face, the movable member moves so that the fixed-length section remains taut. Slack in the data wire and power wire accommodate the movement of the corresponding fixed-length section. A column of display panels can be z-folded for compact storage and can be rapidly deployed to form a large-format display.
