Phone Case Latching Drawer for Secure Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone protective cases lack secure mechanisms to prevent personal items from falling out or being stolen, as they often have unsecured pockets or slots that are not locked.
Innovation Solution
A mobile phone protective case with a latching 'frame and drawer' configuration, featuring a personal item carriage drawer with a latching extension and release actuator, ensuring that personal items are fully enclosed and cannot be removed without proper credentials or breaking the lock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile phone protective case with unsecured pockets or slots is used, then personal items can be carried, but the items can easily fall out or be stolen
Solution Approach 1:
The protective case is divided into separate functional zones: an outer protective shell and an inner drawer compartment with independent latching mechanism. This segmentation allows the case to provide both carrying capability and secure enclosure for personal items
Solution Approach 2:
The drawer compartment is nested within the protective case, creating a within-within structure where the inner drawer provides secure enclosure while the outer case provides protection and carrying function. This nested configuration enables both versatility and security
2Reliability
If a latching mechanism is added to secure personal items, then security is improved, but device complexity increases
Solution Approach 1:
The latching mechanism is extracted as a separate, self-contained component that attaches to the drawer compartment rather than being integrated into the main case structure. This allows the security function to be added without significantly complicating the overall case design
Solution Approach 2:
The latching mechanism is designed to be self-contained and self-operating, requiring minimal integration with the rest of the case structure. The latch works independently to secure the drawer, reducing the complexity burden on the overall system

AI summary
An integrated mobile phone protective case and carrier drawer system for securely containing small personal items, comprising: a regular mobile phone protective case portion; a drawer space integrally contained inside a rear part of the integrated mobile phone protective case; a drawer cover separate from the integrated mobile phone protective case, configured to mate onto the rear part of the integrated mobile phone protective case; a latching extension integrally affixed with the drawer cover; a latch integrally affixed with the integrated mobile phone protective case and configured to latch together with the latching extension; and a release actuator for releasing the latching extension from the latch; wherein: after the drawer cover has been slid onto the integrated mobile phone protective case, the latching extension simultaneously becomes latched together with the latch thereby preventing any personal items contained within the personal item carriage drawer from being removed from the drawer.
