LCD Front Frame Internal Fixing for Smooth Exterior Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display devices have a front frame with visible fixing structures that compromise their appearance, necessitating an additional front cover for decoration, and lack a smooth outer surface suitable for aesthetic integration.
Innovation Solution
The implementation of a fixing post with a fixing hole on the inner surface of the front frame, which corresponds with through holes in the back and middle frames, allowing for internal fixation without external visible structures, using screws or other suitable fixing units to secure the frames together.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fixing structures like holes and bumps are equipped on the front frame to fix components, then the front frame can securely hold components, but the appearance of the front frame becomes unsightly and cannot be used as an appearance part
Solution Approach 1:
The fixing structure is extracted from the front frame and relocated to the back panel. The back panel is provided with through holes and fixing posts that extend through to the front frame's inner surface, allowing components to be secured without any visible fixing structures on the front frame's outer surface. This extraction resolves the contradiction by maintaining fixing capability while preserving appearance quality.
Solution Approach 2:
The fixing structure is moved from the front surface dimension to the back surface dimension. By providing fixing posts on the back panel that pass through to the inner surface of the front frame, the fixing function is achieved in a different spatial dimension (the back and inner surfaces), leaving the outer surface dimension clean and aesthetically pleasing.
2Shape
If a front cover is added to cover the fixing structures on the front frame, then the appearance requirement is met, but the device complexity increases due to additional components
Solution Approach 1:
The front cover is extracted from the necessary components and eliminated entirely. By relocating the fixing structures to the back panel and inner surface of the front frame, the front frame's outer surface naturally achieves appearance quality without requiring an additional front cover, thus reducing device complexity.
Solution Approach 2:
The fixing function and appearance function are merged into a single integrated solution. The back panel with its fixing posts serves both the structural fixing function and the aesthetic appearance function by eliminating the need for separate fixing structures and front cover on the front frame.

AI summary
A liquid crystal display device having a front frame, a back panel, a middle frame and a fixing unit is provided. A fixing post is installed on an inner surface of the frame side of the front frame, the position of the back panel corresponding with the fixing post includes a first through hole, and the position of the middle frame corresponding with the fixing post having a second through hole; wherein the fixing post includes a fixing hole, the fixing post passes through the second through hole and is installed in the first through hole, and the fixing unit is fixed and connected with the fixing hole so that the front frame, the middle frame and the back panel are fixed each other.
