Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tiled display devices face challenges with high cost, difficult maintenance, and poor heat dissipation leading to uneven temperature distribution and display issues such as cyan/white alternation on pure white images due to non-uniform light-emitting efficiency among sub-display panel modules.
Innovation Solution
A box structure with retractable vents and elastic components, including shape memory alloy springs, to control air circulation and temperature uniformity, combined with heat dissipation structures and sliding connection mechanisms to enhance ventilation and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single large-screen display is used, then display size is achieved, but cost increases and maintenance becomes difficult
Solution Approach 1:
The display system is divided into multiple sub-display panel modules that can be tiled together to form a large-screen display. Each module is independently manufacturable and maintainable, solving the contradiction between achieving large display area and maintaining ease of manufacture/maintenance.
2Adaptability or versatility
If sub-display panel modules are tiled together, then flexibility for various display sizes is achieved, but heat dissipation becomes poor leading to uneven temperature distribution
Solution Approach 1:
The patent introduces retractable elements with elastic components that can dynamically adjust the vent openings based on temperature conditions. This dynamic adjustment allows the system to maintain adaptability for various display sizes while actively managing heat dissipation to achieve temperature uniformity across tiled modules.
3Ease of manufacture
If fixed vents are used in the box, then manufacturing is simple, but heat dissipation efficiency is poor
Solution Approach 1:
The vent structure is changed from fixed to retractable, allowing the vent opening area to dynamically adjust based on heat dissipation needs. This maintains manufacturing simplicity while significantly improving heat dissipation efficiency through adaptive opening adjustment.
Solution Approach 2:
The elastic component automatically drives the retractable element to adjust the vent opening based on temperature pressure differences, eliminating the need for external control systems. The system self-regulates heat dissipation based on its own thermal state.
