Backlight Module Bottom Frame Structural Integrity via Folded Tongue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The structural strength of side-light backlight modules is compromised by cable holes in the bottom frame, leading to potential cracking and reduced service life.
Innovation Solution
The design incorporates a clip portion and a foldable tongue piece within the bottom frame to create a diagonal hole for the connector, eliminating the need for additional cable holes, thereby enhancing structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cable holes are provided in the bottom frame to allow connector passage, then connectivity function is achieved, but structural strength deteriorates
Solution Approach 1:
The patent merges the cable hole function with the tongue piece structure by forming the cable hole through the tongue piece itself rather than creating a separate hole in the bottom frame. This integration allows the connector to pass through while maintaining the structural integrity of the bottom frame, as the tongue piece acts as both the structural element and the cable passage.
Solution Approach 2:
The patent utilizes the third dimension (depth/thickness) of the bottom frame to create the cable hole through the tongue piece structure. Instead of creating a planar hole in the bottom frame that compromises strength, the cable hole is formed by folding the tongue piece in a different dimensional approach, allowing connector passage without weakening the primary structural plane.
2Ease of operation
If additional cable holes are created in the bottom frame, then connector passage is enabled, but reliability deteriorates due to increased cracking risk
Solution Approach 1:
The patent combines the cable hole function into the tongue piece structure, eliminating the need for separate cable holes in the bottom frame. This merging approach ensures that the bottom frame maintains its structural integrity and crack resistance while still providing a functional path for the connector through the integrated tongue piece design.
Solution Approach 2:
The patent extracts the cable hole function from the bottom frame structure and relocates it to the tongue piece. By taking out the cable hole requirement from the bottom frame and implementing it through the foldable tongue piece, the bottom frame is freed from the structural weakness that would result from additional holes, thereby improving reliability.

AI summary
A backlight module and a display device are provided. The backlight module includes a light guide, a bottom frame, and a first light bar. The light guide has a first light incident surface. The bottom frame has a clip portion, a first hole, and a first tongue piece, wherein the light guide is disposed in the bottom frame and clipped by the clip portion. A driver board is locked to the first tongue piece, and the first tongue piece is folded from the first hole. The first light bar is disposed between the first light incident surface of the light guide and the bottom frame, and the first light bar has a first connector. The first connector passes through the first hole, so that the first connector is outside the bottom frame.
