Movable Rear Panel Case for Wireless Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective cases for mobile phones with wireless charging capabilities require removal to expose the rear surface for charging, compromising protection and convenience.
Innovation Solution
A protective mobile phone case with a rear panel that can be selectively moved between closed and open orientations, allowing wireless charging without detachment, featuring a perimeter frame, open front face, and storage compartments, adaptable for various phone models and charging units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile phone is placed within a conventional protective case, then the phone receives protection, but the rear surface is covered and wireless charging cannot be performed
Solution Approach 1:
The protective case is divided into a front portion and a rear panel that can be selectively opened or closed. This segmentation allows the rear panel to be opened during wireless charging to expose the charging surface, while remaining closed during normal use to provide protection.
Solution Approach 2:
The rear panel is designed to be movable between closed and open orientations, transforming the static protective case into a dynamic structure that can adapt its configuration based on the operational mode (protection vs. charging).
2Ease of operation
If the protective case is removed to enable wireless charging, then charging access is achieved, but protection is lost
Solution Approach 1:
By segmenting the case into a removable or movable rear panel, the design allows selective access to the charging surface without requiring complete removal of the protective case, thus maintaining protection while enabling charging.
Solution Approach 2:
The rear panel is extracted as a separate functional element that can be independently opened or removed, providing access to the wireless charging surface while the front portion of the case remains in place to continue providing protection.
3Reliability
If a conventional protective case is used, then comprehensive protection is provided, but the case must be detached for charging which reduces convenience
Solution Approach 1:
The dynamic rear panel that opens for charging eliminates the need to completely detach and reattach the case, saving time and effort while maintaining comprehensive protection during normal use.
Solution Approach 2:
The case is pre-configured with an openable rear panel specifically designed for charging access, so no additional actions (detaching and reattaching the case) are needed when charging is required.
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
Enables wireless charging while maintaining protection and convenience by exposing the rear surface for charging without removing the case, accommodating different charging units and phone sizes, and providing additional storage and access features.
Implementation Method 1
the rear surface or other appropriate portion of the mobile phone is disposed within an appropriate and/or predetermined induction range of the transmitting coil of the wireless recharging unit

AI summary
A mobile telephone case that includes a housing structured to receive a mobile telephone, the housing includes a perimeter frame disposed about a perimeter of the mobile telephone to substantially cover and protect the mobile telephone, an at least partially open front face to provide access to a display screen of the mobile telephone, and a protective rear panel that is at least partially movable between an open orientation and a closed orientation when the housing is operatively disposed on the mobile telephone. The protective rear panel substantially covers and protects a rear surface of the mobile telephone when in the closed orientation, with at least a portion thereof being at least partially separable from the perimeter frame to define the open orientation that provides wireless charging access to the rear surface of the mobile telephone with the housing still disposed on the mobile telephone.
