Backlight Module Frame with Elastic Shock Absorbers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid crystal displays (LCDs) with conventional backlight modules are prone to damage from shocks due to the lack of protection for the light guide plate and liquid crystal panel, as they do not absorb impact effectively.
Innovation Solution
Incorporating elastic members, such as curved lugs or coil springs, into the frame of the backlight module to absorb shock and distribute it across the outer surface, thereby protecting the internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the backlight module uses a rigid frame structure, then the manufacturing precision and structural stability are improved, but the shock resistance and protection against impact damage deteriorate
Solution Approach 1:
The patent applies beforehand cushioning by integrating elastic members (such as rubber or silicone materials) into the frame structure before shock occurs. These elastic members are pre-installed at strategic locations to absorb and dissipate impact energy when shock occurs, protecting the light guide plate and liquid crystal panel from damage while maintaining the rigid frame's structural stability during normal operation.
2Object-affected harmful factors
If elastic members are added to the frame, then the shock absorption and protection capability are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent applies merging by integrating elastic members directly into the frame structure as a unified component. The elastic members are combined with the frame body through embedding or attachment methods, creating a composite structure that provides shock absorption functionality without requiring separate protective components. This approach reduces overall device complexity compared to adding independent protective mechanisms.
3Object-affected harmful factors
If elastic members are provided at outer side surfaces, then the shock distribution and protection effectiveness are improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by positioning elastic members at specific locations on the outer side surfaces of the frame where shock impact is most likely to occur. Rather than uniformly distributing shock protection throughout the entire frame, the elastic members are strategically placed at corner portions and edge areas that experience the highest impact forces during falls or bumps, providing targeted shock absorption where it is most needed.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The elastic members effectively absorb and distribute shock, reducing the likelihood of damage to the liquid crystal panel and light guide plate during falls or bumps, enhancing the durability of the LCD.
Implementation Method 1
at least one elastic member provided at an outer side surface of the main body

AI summary
A backlight module (200) typically used in a liquid crystal display (LCD) (20) includes at least one light emitting unit (250), and a frame (260) receiving the at least one light emitting unit therein. The frame includes a main body (261), and at least one elastic member provided at an outer side surface of the main body. The LCD employing the backlight module can be prevented from being damaged if the LCD falls to the ground or is bumped.
