Arcuate Cushioning Pad for Display Screen Stress Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cushioning devices for display screens have a small contact area between the flat silicone and the screen, leading to a poor cushioning effect and increased risk of cracking during transportation due to stress concentration.
Innovation Solution
A cushioning device with a cushioning block body featuring a holding groove with an arcuate surface and a cushioning pad that corresponds to the groove's shape, increasing the contact area and reducing pressure per unit area, thereby enhancing the cushioning effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flat silicone is used to contact the display screen, then the cushioning device can protect the display screen from shocks and impacts, but the contact area between the flat silicone and the display screen is limited by the size of the cushioning block body, causing stress concentration and poor cushioning effect
Solution Approach 1:
The patent applies curvature by designing the contact surface of the cushioning pad as an arcuate surface that matches the curvature of the display screen edge. This curved surface allows the cushioning pad to conform to the screen's geometry, significantly increasing the contact area from a limited flat surface to a broad arcuate interface, thereby distributing stress more effectively and eliminating stress concentration points.
Solution Approach 2:
The patent changes the geometric parameters of the cushioning pad by designing it with an arcuate cross-sectional shape that corresponds to the display screen's curvature. This parameter change in shape allows the cushioning pad to achieve optimal contact area without being constrained by the overall size of the cushioning block body, resolving the contradiction between limited size and insufficient contact area.
2Area of stationary object
If the size of the cushioning block body is increased to enlarge the contact area, then the cushioning effect can be improved, but the device complexity and space occupation will increase
Solution Approach 1:
The patent segments the cushioning device into two functional parts: a compact cushioning block body and a separately attached cushioning pad. This segmentation allows the cushioning pad to be designed with an optimized arcuate shape for maximum contact area, while the block body remains compact. The pad is attached to the block body, combining the benefits of both compact structure and large contact area without increasing overall device complexity.
Solution Approach 2:
The patent utilizes the dimensional flexibility of the cushioning pad by designing it as a separate element that can be attached to the block body. This allows the contact surface to extend in dimensions that would otherwise require a much larger block body, effectively using the pad's dimensional freedom to achieve large contact area without proportionally increasing the block body size or device complexity.
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 solution significantly improves the cushioning effect by increasing the contact area between the display screen and the cushioning device, reducing the risk of cracking and ensuring stable protection during transportation and storage.
Implementation Method 1
the extrados is adhered to the arcuate surface via an adhesive layer, so that the cushioning pad is fixedly connected with the cushioning block body
Implementation Method 2
the cushioning holes are filled with an elastomeric material
