Display Panel Positioning Member for Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As display panels increase in size, the larger tolerance ranges and differing expansion coefficients between the panel and glue frame lead to instability and potential breakage during assembly, causing light leakage, malfunction, and wear on structural components.
Innovation Solution
A display panel positioning member made of shock-absorbing material with damping properties, featuring a supporting portion between the panel and glue frame and a cushioning portion between the panel and edge frame, providing static friction and absorbing impact to enhance assembly stability and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the gap between the glue frame and the display panel is enlarged to accommodate different expansion coefficients, then the display panel can be mounted in the glue frame, but the vibration displacement and impact force between the display panel and sides of the glue frame become larger, causing the display apparatus to be easily broken
Solution Approach 1:
The patent applies beforehand cushioning by introducing a cushioning portion in the positioning member that is configured to contact the side of the display panel. This cushioning portion is designed to absorb impact forces and reduce vibration displacement before they can cause damage to the assembly, thereby resolving the contradiction between mounting adaptability and assembly stability.
Solution Approach 2:
The positioning member acts as an intermediary component between the display panel and the glue frame. It includes a supporting portion that contacts the display panel and a cushioning portion that contacts the glue frame, mediating the interaction between these two components to reduce impact forces and vibration while maintaining proper mounting.
2Adaptability or versatility
If the gap between the glue frame and the display panel is enlarged to accommodate different expansion coefficients, then the display panel can be mounted in the glue frame, but friction and tension may be caused between structures such as shading strips and the glue frame, causing the structures to be broken or worn
Solution Approach 1:
The positioning member serves as an intermediary that reduces direct friction and tension between the display panel and the glue frame. By distributing forces through its supporting and cushioning portions, it protects structures like shading strips from excessive friction and tension, preventing breakage and wear.
Solution Approach 2:
The cushioning portion is designed to absorb impact forces and reduce vibration before they can cause friction and tension to exceed the structural limits of components like shading strips. This beforehand cushioning prevents the structures from being broken or worn.
3Ease of operation
If a larger gap is provided between the glue frame and the display panel, then the display panel can be mounted, but the distance of movement of the display panel becomes longer, increasing friction and tension
Solution Approach 1:
The positioning member acts as an intermediary that reduces the effective movement distance between the display panel and the glue frame. By providing a supporting portion that contacts the display panel and a cushioning portion that contacts the glue frame, it minimizes the gap utilization and reduces friction and tension during movement.
