Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices experience image quality degradation due to non-uniform temperature distribution leading to color sense differences and warpage from thermal expansion, particularly in OLED and LED display modules.
Innovation Solution
A display device design incorporating a rail frame and magnets to couple display modules, using module brackets and magnets to minimize temperature differences and warpage, allowing easy attachment and detachment, and facilitating heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If display modules are rigidly fixed to prevent warpage, then structural stability improves, but thermal expansion and color sense differences worsen due to temperature distribution
Solution Approach 1:
The support structure is divided into multiple independent support parts (first support part, second support part, etc.) that can independently adjust to local thermal variations. Each support part corresponds to specific boundary areas between display modules, allowing localized adaptation to thermal expansion without rigidly constraining the entire structure.
Solution Approach 2:
Different support parts are positioned at specific boundary areas where thermal expansion effects are most prominent. The support structure provides localized support exactly where needed (at boundaries between adjacent display modules) rather than uniform support across the entire display, addressing thermal expansion effects at their source while maintaining overall structural stability.
2Stability of the object's composition
If display modules are firmly fixed to prevent warpage, then structural stability improves, but ease of replacement worsens
Solution Approach 1:
The support parts are designed to be detachably coupled to display modules, allowing the structure to transition between a fixed state (when modules are attached for stability) and a movable state (when modules need to be replaced). This dynamic coupling mechanism maintains structural stability during operation while enabling easy module replacement when needed.
3Stability of the object's composition
If multiple support structures are added to prevent warpage, then structural stability improves, but device complexity increases
Solution Approach 1:
The support parts serve multiple functions simultaneously: they provide structural support to prevent warpage, facilitate thermal management by creating spacing, and enable easy module replacement through detachable coupling. This multi-functionality reduces the need for separate components for each function, thereby reducing overall device complexity while maintaining structural stability.
