Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional large tiled LED displays are cumbersome due to heavy, rigid structures and complex cabling, which affects stability, maintenance, and visual uniformity, and are limited in flexibility and modularity, making them impractical for outdoor use and large-scale deployments.
Innovation Solution
A flexible tiled display system using modular, flexible substrates with conducting tracks that extend from one edge to the opposite edge, allowing for easy assembly and maintenance, with power, data, and control signals provided through separate conductive tracks, and the use of push pins and conductive glue for connections, enabling flexible deployment and redundancy in signal delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional rigid support structures are used to support display tiles, then structural stability is improved, but device weight and complexity increase
Solution Approach 1:
The patent replaces rigid support structures with flexible substrates that have mechanical properties similar to human skin. The display tiles are mounted directly on these flexible substrates, eliminating the need for heavy metallic support structures while maintaining structural stability through the flexibility and tensile strength of the substrate material.
Solution Approach 2:
The patent divides the display into modular flexible tiles that can be independently assembled and disassembled. Each tile contains its own flexible substrate with conducting tracks, allowing for simplified assembly without requiring complex rigid support structures to hold multiple tiles in place.
2Reliability
If conventional cabling systems are used to provide power and signals to display tiles, then electrical connections are established, but device complexity and cable management difficulty increase
Solution Approach 1:
The patent merges the electrical connection function into the mechanical assembly process. Conducting tracks are printed directly on the flexible substrate, and electrical contacts are made through conductive adhesive or pressure contacts when tiles are assembled, eliminating the need for separate cabling systems and connectors.
Solution Approach 2:
The patent replaces mechanical cabling systems with printed conducting tracks on flexible substrates. Electrical signals and power are transmitted through these printed tracks rather than through physical cables, significantly reducing complexity and improving reliability by eliminating connection points that could fail.
3Ease of manufacture
If display tiles are assembled with visible seams between them, then manufacturing is simplified, but visual uniformity deteriorates
Solution Approach 1:
The flexible substrate allows the display tiles to conform and bond closely together, minimizing gaps and seams. The flexibility enables the tiles to be pressed together with uniform pressure, creating tight joints that are less visible and improve overall visual uniformity while maintaining ease of assembly.
