Mobile Phone Privacy Case with Sliding Camera and Microphone Covers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smartphone cases fail to provide robust protection against unauthorized recording or image capture due to partial acoustic shielding and manual adjustments required for camera and microphone covers, which are impractical and lose effectiveness over time.
Innovation Solution
A mobile phone case with slidable upper and lower frame portions that move along rail assemblies, featuring a selector assembly to automatically switch between open and closed configurations, using dampening members to block audio and visual signals when closed, and allowing normal functionality when open.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stickers are used to cover camera lenses and plug microphone ports, then manual application and removal is required, but they lose stickiness over time and require frequent replacement
Solution Approach 1:
The patent employs dynamic shutters that can move between open and closed positions to cover or expose camera lenses and microphone ports. This mechanical movement replaces static stickers, providing reliable coverage that can be activated or deactivated as needed without losing effectiveness over time.
Solution Approach 2:
The shutters are designed to be automatically actuated by the smartphone itself, eliminating the need for manual application and removal by the user. The system serves itself by using the phone's existing mechanisms to control the coverage of cameras and microphones.
2Reliability
If physical shutters are integrated into the phone case with sliding/hinging mechanism, then camera lenses are blocked efficiently, but microphones still capture sound due to partial acoustic shielding
Solution Approach 1:
The patent divides the phone case into separate upper and lower portions, each with independent shutter mechanisms. The upper portion controls camera and microphone coverage, while the lower portion independently controls the other microphone and speaker. This segmentation allows each component to be optimized for its specific function, ensuring complete acoustic shielding for microphones while maintaining effective camera blocking.
3Adaptability or versatility
If upper and lower frame portions are made independently slidable along rails, then selective coverage of front or back camera is achieved, but device complexity increases
Solution Approach 1:
The patent combines the shutter mechanisms for the upper and lower frame portions into a single integrated system controlled by one selector assembly. This merging approach allows independent slidable portions to be coordinated through a unified control mechanism, providing selective camera coverage while reducing the overall complexity compared to completely separate control systems.
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
Provides robust protection against privacy breaches by automatically covering cameras and microphones without manual adjustments, ensuring uninterrupted smartphone use.
Implementation Method 1
The upper and lower frame portions include dampening members configured to block audio signals and visual images when the upper and lower frame portions are in the closed configurations, respectively.
Implementation Method 2
A cradle portion capable of receiving the smartphone in a friction fit configuration

AI summary
A mobile phone case includes a cradle for receiving the smartphone in a friction fit configuration, an upper frame portion coupled to an upper section of the cradle and a lower frame portion coupled to a lower section of the cradle via upper and lower rail assemblies, respectively. The upper and lower frame portions are slidably movable between a closed configuration covering the upper and lower microphones and the front and rear cameras of the smartphone, respectively, and an open configuration not covering them. The upper and lower frame portions include dampening members configured to block audio and visual signals when closed. The mobile phone case includes a spring-biased selector assembly coupled to the cradle portion and operatively coupled to the upper and lower frame portions for simultaneously urging the upper and lower frame portions toward the open configuration when actuated.
