Protective Case Edge Segmentation for Gesture Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Protective cases for mobile devices with large displays or no display edge hinder accessibility and operability, as the display edge is covered, preventing effective use of gesture functions and limiting additional feature implementation.
Innovation Solution
A protective case design featuring a second edge section that is lower and sloping, allowing seamless finger operation, with different edge heights and textures to facilitate gesture-based interactions while maintaining protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the protective case has a uniform high edge to fully protect the display device, then the protection capability is improved, but the accessibility and operability of the display edge is worsened
Solution Approach 1:
The edge of the protective case is divided into multiple sections: a first edge section with higher height for protection, and a second edge section with lower height for operability. This segmentation allows different parts of the same component to serve different functions, resolving the contradiction between protection and accessibility.
Solution Approach 2:
Different regions of the protective case edge are given different heights and properties. The first edge section has higher height to provide protection, while the second edge section has lower height to enable finger access. This local differentiation allows the protective case to simultaneously achieve both protection and operability requirements.
2Reliability
If the protective case fully covers the display edge, then the protection capability is improved, but the ability to implement gesture functions is worsened
Solution Approach 1:
The edge is segmented into protective and operational zones, allowing gesture functions to be implemented on the second edge section while the first edge section maintains protection. This enables the device to support modern gesture-based interactions without sacrificing protection.
Solution Approach 2:
The protective case provides full protection in certain areas (first edge section) while maintaining operational accessibility in other areas (second edge section). This local quality differentiation enables gesture functions to be implemented where needed while maintaining overall protection.
3Reliability
If the protective case has a high edge for protection, then the protection capability is improved, but the accessibility for finger operation is worsened
Solution Approach 1:
The edge is divided into a first edge section with higher height for protection and a second edge section with lower height for finger access. This segmentation creates distinct functional zones that simultaneously provide both protection and accessibility.
Solution Approach 2:
Different heights are assigned to different parts of the edge: the first edge section has higher height for protection, while the second edge section has lower height to allow fingers to easily access and operate the display. This local quality approach resolves the contradiction between protection height and finger accessibility.
