LCD Module Fixing Device with Elongated Insert Holes for Flush Surface Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixing structures for LCD modules and faceplates fail to maintain a flush surface due to variations in module thickness, leading to protrusion or sinking issues, making operation inconvenient.
Innovation Solution
A fixing device with a frame, fixing members, elongated insert holes, projecting posts, locking plates, and locking fasteners allows for adjustable positioning of the LCD module and faceplate, ensuring the module's surface remains flush with the faceplate, using a spring clamp plate and locking mechanism to secure the module and circuit board.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional fixing structure with a frame is used to assemble LCD modules and faceplates, then the assembly process is simple, but the LCD module surface cannot be kept flush with the faceplate surface due to thickness variations
Solution Approach 1:
The fixing structure incorporates adjustable components that allow dynamic adaptation to different LCD module thicknesses. The adjustment mechanism enables the fixing structure to change its configuration to accommodate varying module dimensions, thereby maintaining surface flushness across different product variants without requiring complete redesign of the assembly process.
Solution Approach 2:
The invention utilizes adjustable parameters within the fixing structure, such as movable positioning elements or variable-height support components, that can be modified to match different LCD module thicknesses. This parameter adjustment capability allows the same fixing structure to achieve precise surface alignment for modules of varying thicknesses, resolving the contradiction between manufacturing simplicity and precision.
2Adaptability or versatility
If LCD modules of different thicknesses are assembled with faceplates using conventional structures, then various module specifications can be accommodated, but the LCD module may protrude or sink making operation inconvenient
Solution Approach 1:
The fixing structure is designed as a universal assembly solution that can accommodate multiple LCD module specifications and thickness variations. By incorporating adjustable components and modular elements, the same fixing structure performs the multi-function of adapting to different module dimensions while maintaining consistent surface alignment, thereby ensuring operational convenience across various product configurations.
Solution Approach 2:
The adjustable nature of the fixing structure allows it to dynamically adapt its configuration based on the specific LCD module being assembled. This dynamic adjustment capability ensures that regardless of the module thickness or specification, the fixing structure can be tuned to achieve proper surface alignment, preventing protrusion or sinking issues that would impair operational convenience.
3Ease of operation
If frequent pressing and operation of the LCD module is performed, then user interaction is enhanced, but the LCD module sinks into the faceplate and cannot recover its original state
Solution Approach 1:
The fixing structure incorporates preliminary counteracting measures through its adjustable and supportive design. By providing adequate support and proper positioning before user interaction occurs, the structure prevents the LCD module from sinking under repeated pressing. The adjustment mechanism ensures that the module is held at the correct height and stability, counteracting the potential harmful effect of frequent pressing that would otherwise cause sinking and prevent recovery.

AI summary
A fixing device for an LCD module and a faceplate includes a frame having one side fixing an LCD module and another side provided with plural fixing plates respectively bored with an elongated insert hole. A circuit board is secured at a rear side of a faceplate and provided with plural locking plates corresponding with the fixing plates so that the fixing plates of the frame can be respectively secured with the locking plates. Thus, relative positions of an LCD module and a faceplate can be adjusted and hence LCD modules different in thickness can be firmly fixed with a faceplate and the surface of the LCD module can be stably kept flush with the surface of the faceplate.
