Integrally-Formed Frame Backlight Module Eliminates Clamping Debris
Solution Overview
Problem
Conventional backlight modules with a middle case clamping structure often result in defective products due to debris generation and limited thickness, as they require a back plate and middle case connection, which increases weight and thickness.
Innovation Solution
A backlight module with an integrally-formed frame that encases a light guide plate, featuring a bendable section for easy assembly and no clamping structure, made of plastic with specific hardness and texturing for aesthetic appeal, eliminating the need for a middle case and back plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a middle case and back plate clamping structure is used, then the backlight module can be assembled, but debris is generated and clamped to the back plate causing product defects
Solution Approach 1:
The patent merges the middle case and back plate into a single integrally-formed frame structure. This eliminates the clamping connection between separate components, preventing debris generation and clamping defects while maintaining assembly capability through the integral design.
2Strength
If a middle case and back plate are used, then structural support is provided, but weight and thickness increase
Solution Approach 1:
The patent combines multiple structural components (middle case and back plate) into a single integrally-formed frame, reducing the total number of parts and overall weight while maintaining structural support through the optimized integral design.
Solution Approach 2:
The integrally-formed frame utilizes thin-walled plastic structures that provide adequate structural support with minimal weight, replacing the heavier multi-component metal or rigid plastic clamping structure.
3Strength
If a middle case and back plate are used, then structural support is provided, but thickness increases
Solution Approach 1:
The patent integrates the middle case and back plate functions into a single thin-walled integrally-formed frame, eliminating the cumulative thickness of multiple stacked components while maintaining structural support through the integral geometry.
Solution Approach 2:
The frame employs thin-walled plastic construction that provides necessary structural support with minimal thickness, replacing the thicker multi-layer clamping structure of conventional designs.
4Ease of manufacture
If separate middle case and back plate are clamped together, then assembly is achieved, but clamping debris is generated
Solution Approach 1:
The patent eliminates the clamping operation between separate components by merging them into an integrally-formed frame. This prevents clamping debris generation entirely while maintaining assembly capability through the integral manufacturing process.
