Mobile Phone Case With Movable Rear Panel 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 for physical and visual access and a storage compartment, 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 protection is provided, 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 moved between closed and open orientations. This segmentation allows the rear panel to be opened for wireless charging while the front portion maintains protection, resolving the contradiction between continuous protection and charging access.
Solution Approach 2:
The rear panel is designed to be movable rather than fixed, allowing it to transition between closed (protective) and open (charging-enabled) states. This dynamic design enables the case to adapt its configuration based on whether protection or wireless charging is the priority, eliminating the need for complete case removal.
2Ease of operation
If the protective case is removed to enable wireless charging, then charging is facilitated, but protection is lost
Solution Approach 1:
By segmenting the case into a front portion and a movable rear panel, the invention allows only the necessary portion (rear panel) to be opened for charging while the front portion remains closed and protective. This eliminates the need to remove the entire case.
Solution Approach 2:
The case design applies different functional qualities to different parts: the front portion maintains a closed protective state, while the rear panel provides localized access for charging. This local differentiation allows protection and charging to coexist without requiring complete case removal.
3Reliability
If a conventional protective case is used, then comprehensive protection is provided, but case removal is required for charging
Solution Approach 1:
The movable rear panel eliminates the need to completely remove and reattach the case for charging. Users can simply open the rear panel, perform wireless charging, and close it again, significantly reducing the time loss associated with case removal and reattachment while maintaining comprehensive protection.
4Reliability
If the rear panel is kept closed for protection, then protection is maintained, but wireless charging is blocked
Solution Approach 1:
The dynamic rear panel allows users to open it specifically when wireless charging is needed, maintaining protection during normal use while enabling energy transfer during charging. This resolves the contradiction by allowing the case to switch between protective and charging-enabled states as needed.

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.
