Backlight Module Front-Side Circuit Board Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembling process of liquid crystal display devices is cumbersome and prone to damage, especially for large-size products like televisions, due to the need to overturn the backlight module to fix the screen driving board on its backside.
Innovation Solution
A backlight module design featuring a fixing member and insertion clamp system that allows the circuit board to be inserted and fixed without overturning the module, using a mounting portion and clamping portion to secure the screen driving board between the fixing member and insertion clamp, thereby simplifying the assembly and reducing the risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the backlight module is overturned to fix the screen driving board on the back side, then the circuit board can be fixed, but the assembling process becomes cumbersome and laborious
Solution Approach 1:
Instead of overturning the backlight module to access the back side for fixing the circuit board, the patent inverts the approach by providing a fixing structure on the front side of the backlight module. The fixing member extends from the front surface, allowing the screen driving board to be fixed without overturning the module, thus simplifying the assembling operation.
Solution Approach 2:
The fixing structure is segmented into a fixing member extending from the front surface and a clamping member extending from the back surface. This segmentation allows the circuit board to be clamped between the two members without requiring overturning of the backlight module, making the assembly process more convenient.
2Reliability
If the backlight module is overturned to fix the screen driving board, then the circuit board can be secured, but damage to the liquid crystal panel is likely
Solution Approach 1:
The patent eliminates the need to overturn the backlight module by providing a fixing structure on the front side. The fixing member extends from the front surface to clamp the circuit board, allowing the assembly operation to be performed without overturning, thereby preventing damage to the liquid crystal panel.
Solution Approach 2:
The fixing member acts as an intermediary structure that enables the circuit board to be fixed without direct contact or force applied to the liquid crystal panel during the assembly process. By clamping the circuit board between the fixing member and clamping member, the panel is protected from damage.
3Productivity
If a traditional fixing structure is used without insertion clamp, then the structure is simpler, but the assembly efficiency is lower and more time-consuming
Solution Approach 1:
The fixing member and clamping member are pre-positioned on the backlight module at predetermined locations. The fixing member extends from the front surface and the clamping member extends from the back surface, creating a pre-configured clamping structure that enables rapid assembly of the circuit board without requiring complex operations.
Solution Approach 2:
The fixing structure is designed to be self-aligning and self-clamping. The fixing member and clamping member are positioned to automatically guide and secure the circuit board in place, reducing the need for additional adjustment or complex assembly operations, thereby improving assembly efficiency.
