Rigid Screen Protector Lip for Mobile Device Case
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective mobile device cases offer limited scratch protection for touch screens and are difficult to remove without damaging the film or the case, as they are affixed to the device or case and made of non-rigid, flexible materials that provide little impact protection.
Innovation Solution
A substantially rigid and transparent screen protector with a perimeter lip and ridge is designed to fit within a mobile device case, providing impact protection and easy removal by snapping or sliding into place, while maintaining access to controls and being removable without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible protective film is used, then the film can be easily applied and removed, but it provides little scratch protection and impact protection
Solution Approach 1:
The patent changes the physical parameter of the protective film from flexible to rigid. The screen protector is made of a rigid material that maintains its shape and provides structural support, enabling it to resist scratches and impacts while still being installable and removable from the mobile device case.
2Strength
If a rigid protective film is used, then scratch protection is improved, but the film becomes difficult to remove without damaging the film or case
Solution Approach 1:
The patent introduces a lip structure that segments the rigid screen protector from the case surface. This lip creates a physical separation between the protective film and the case, allowing the rigid film to be easily gripped and removed without damaging either the film or the case.
Solution Approach 2:
The patent adds a third dimension by extending the lip outward from the plane of the screen protector. This dimensional extension provides a gripping surface that facilitates easy removal of the rigid protective film without requiring damage to the film or case.
3Ease of operation
If the screen protector is made of non-rigid material, then it is flexible and easy to apply, but it provides little impact protection
Solution Approach 1:
The patent changes the rigidity parameter of the protective material. The screen protector is made of a rigid material that maintains its shape under impact forces, providing structural support and impact protection while still being installable and removable from the mobile device case.
