Flexible Coupling Protection Cover for Compact Portable Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protection covers for portable devices with touch screens increase the device's volume and do not provide effective cleaning for the screen, as the rear cover is mounted on the rear case and the front cover lacks cleaning capabilities.
Innovation Solution
A protection cover design that integrates a front cover with superfine fibers for cleaning and a rear cover that serves as a battery cover, using a flexible coupling member to maintain compactness and replace the original case frame, allowing the front cover to pivot and securely attach to the rear cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rear cover is mounted on the rear case of the portable apparatus, then the protection cover provides structural support and protection, but the total volume and dimension of the portable apparatus increase
Solution Approach 1:
The rear cover is designed to serve dual functions: it acts as both a protective cover component and a battery cover for the portable apparatus. By integrating the battery cover function into the rear cover, the invention eliminates the need for a separate battery cover structure, thereby reducing the overall volume while maintaining protection capability.
2Ease of manufacture
If the front cover is made simple for easy manufacturing, then production cost is reduced, but the front cover lacks cleaning ability for the screen
Solution Approach 1:
The front cover is constructed using composite materials, specifically combining a base material with superfine fibers attached to the screen-facing surface. This composite structure provides both the manufacturing simplicity of the base material and the cleaning functionality of the superfine fibers, resolving the contradiction between ease of manufacture and cleaning capability.
3Stability of the object's composition
If a rigid coupling system is used to attach the front cover to the rear cover, then structural stability is improved, but the device loses flexibility and ease of handling
Solution Approach 1:
The coupling member is designed as a flexible component that can bend and flex, allowing the front cover to pivot relative to the rear cover. This flexible coupling system maintains structural stability when connected while enabling ease of operation during use, resolving the contradiction between stability and flexibility.
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 reduces the overall volume of the portable device while providing effective screen cleaning and maintaining a slim appearance by utilizing superfine fibers for dust and liquid absorption and a flexible coupling system for easy handling.
Implementation Method 1
One side of the front cover facing the screen of the portable apparatus may employ superfine fibers
Implementation Method 2
One side of the front cover facing the screen of the portable apparatus may employ a material having a cleaning ability

AI summary
A protection cover and a portable apparatus including the same are provided. The protection cover includes a front cover, a rear cover, and a coupling member. The front cover is mountable on the portable apparatus and covers a screen of the portable apparatus. The coupling member is formed of a flexible material such that the front cover is pivotable between and open and a closed position. The rear cover is mounted on the backside of the portable apparatus to serve as a rear case of the portable apparatus. The coupling member is integrally coupled with the front cover and separably coupled with the rear cover. According to the above structure, the protection cover can minimize the total volume and dimensions of the portable apparatus after it is mounted.
