Rubber Frame with Localized Thickness for Display Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable devices with liquid crystal display panels, such as smartphones, face structural weakness and breakage at single-layer glass positions due to the removal of metal backplates for thinner designs, leading to susceptibility to damage during drops or collisions.
Innovation Solution
A rubber frame with a protective structure member, made of the same material and integrally formed with the rubber frame body, is used to provide a cushioning effect in the bonding region, narrowing the gap between the display panel and touch screen, and dispersing external forces for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If metal backplates are removed from backlight modules to achieve thinner products, then the thickness of portable devices is reduced, but the overall structural strength of the products deteriorates
Solution Approach 1:
The rubber frame is configured with different thicknesses at different locations: a first thickness in the bonding region and a second thickness in non-bonding regions, where the first thickness is greater than the second thickness. This local quality differentiation provides enhanced protection specifically at the vulnerable bonding region while maintaining the overall thin profile of the device, thus resolving the contradiction between device thickness and structural strength.
Solution Approach 2:
The invention uses rubber material for the frame instead of traditional metal backplates. The rubber material provides both cushioning protection and structural support, enabling the frame to simultaneously achieve thickness reduction and maintain structural strength through its material properties and optimized geometry.
2Length of moving object
If the rubber frame thickness is uniformly reduced to achieve thinner devices, then device thickness is reduced, but the protective effect at bonding regions deteriorates
Solution Approach 1:
The rubber frame is configured with different thicknesses at different locations: a first thickness in the bonding region and a second thickness in non-bonding regions, where the first thickness is greater than the second thickness. This local quality differentiation provides enhanced protection specifically at the vulnerable bonding region while maintaining the overall thin profile of the device, thus resolving the contradiction between device thickness and structural strength.
3Reliability
If the rubber frame is designed with increased thickness at bonding regions to enhance protection, then protective effect is improved, but device complexity increases
Solution Approach 1:
The invention integrates the protective function directly into the rubber frame structure itself by configuring varying thicknesses within the frame body, rather than adding separate protective components or layers. This merging of protection function into the existing frame structure enhances protection at bonding regions while avoiding additional structural complexity.
