Elastic Fixing Device for Display Panel Strain Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing devices for in-vehicle display panels often cause strain due to the transmission of fastening forces, leading to issues like black unevenness when the display is lit, especially as the panel and bracket masses increase.
Innovation Solution
A fixing device with first and second fixing pieces, each formed from a metal plate and bent perpendicularly, featuring elongate hole portions and fastening portions that allow for elastic deformation when fastened, reducing the stress applied to the panel member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the rigidity of the attachment piece is increased to firmly hold the panel member, then the holding strength is improved, but the fastening force is transmitted to the panel member causing strain
Solution Approach 1:
The attachment piece is designed with elastic deformability, allowing it to flex during fastening to absorb fastening forces and prevent strain transmission to the panel member, while maintaining sufficient rigidity for firm holding
Solution Approach 2:
The patent optimizes the thickness and material properties of the attachment piece to achieve a balance between rigidity for holding strength and elasticity for force absorption, preventing strain on the panel
2Stability of the object's composition
If the thickness of the attachment piece is increased to prevent panel movement due to vibration, then the stability is improved, but the fastening force transmission causing strain increases
Solution Approach 1:
The attachment piece incorporates elastic properties that allow it to dampen vibrations and stabilize the panel without transmitting excessive fastening forces that would cause strain
Solution Approach 2:
The elastic attachment piece acts as a cushioning element that absorbs and dissipates vibration energy before it can transmit to the panel, preventing both movement and strain
Applied Scientific Principles
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 device effectively increases rigidity for firm holding while minimizing strain on the display panel, preventing black unevenness and ensuring secure attachment without excessive stress.
Implementation Method 1
the attachment piece is made elastically deformable, so that the restraining force in the X direction, which is the elastic deformation direction of the attachment piece, is less likely to act on the bracket and the display cell held by the bracket

AI summary
A panel case of a display panel is provided with a first fixing piece extending rearward (in the Y2 direction), and a female threaded hole is formed in the first fixing piece. A support bracket is provided with a second fixing piece extending rearward (in the Y2 direction), and an attachment hole is formed in the second fixing piece. The first fixing piece has a first elongate hole portion opened between the female threaded hole and a base portion, and the second fixing piece has a second elongate hole portion formed between the attachment hole and a base portion. Therefore, the fastening force due to a fixing screw is less likely to be transmitted to the base portion of the first fixing piece, and strain of the display panel can be regulated.
