Display Device Fixing Member Without Spacer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display devices face challenges in reducing thickness due to the need for spacers between the light emitting module and the fixing member during assembly, which causes friction and complicates the assembly process.
Innovation Solution
A display device structure that includes a back plate with a light emitting module on its inner surface and a light guide plate opposite to it, where a fixing member with a U-shaped cross-sectional structure leans on the outer surface of the back plate, allowing the light emitting module to be fixed without a spacer, thus reducing the device's thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spacer is used to separate the light emitting module and the fixing member during assembly, then friction and interference between components are avoided, but the thickness of the display device increases
Solution Approach 1:
The patent removes the spacer component from the assembly structure. The fixing member is designed to directly contact and fix the light emitting module without requiring a spacer, thereby eliminating the thickness contribution of the spacer while maintaining proper assembly and reducing friction through optimized contact surfaces.
2Ease of operation
If the light emitting module and the fixing member are separated by a spacer, then friction during assembly is reduced, but the assembly process becomes more complex
Solution Approach 1:
The spacer is extracted from the assembly structure, simplifying the overall device complexity. The fixing member is designed with integrated fixing functionality that directly contacts the light emitting module, eliminating the need for additional spacer components and reducing assembly complexity.
Solution Approach 2:
The fixing functionality and the structural support function are merged into a single fixing member that directly contacts and fixes the light emitting module. This consolidation eliminates the need for separate spacer components, reducing both device complexity and assembly steps.
3Length of stationary object
If the thickness of the display device is reduced by eliminating spacers, then the device becomes more compact, but friction and interference between the light emitting module and fixing member increases
Solution Approach 1:
The spacer is removed to reduce device thickness, and the fixing member is designed to directly contact the light emitting module with optimized contact surfaces that minimize friction and interference while maintaining proper positioning and fixing functionality.
