Rotating Safe Door Mechanism for Pry-Resistant Quick Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safe designs face issues such as pry-open vulnerabilities, limited access space, and ease of removal due to size and weight, which compromise security and quick access to valuables like guns, especially in situations requiring rapid retrieval during intrusions.
Innovation Solution
A safe with a rotatable door and energy storage mechanism that automatically opens upon proper access authorization, coupled with a barbed plate attachment to a bed system, providing secure anchoring and minimizing removal risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional safe with a hinged door is used, then access to valuables is provided, but the door can be pried open by inserting a lever between the box and door
Solution Approach 1:
The patent inverts the conventional hinged door design by using a rotatable door that opens inward into the safe body rather than swinging outward. This inversion eliminates the gap between the door and box where a lever could be inserted, preventing prying attacks while maintaining access functionality through rotation.
Solution Approach 2:
The patent converts the potential harm of a gap between door and box (which allows prying) into a benefit by designing the door to rotate within the box body. The rotation mechanism uses the internal space of the safe to accommodate the door's movement, turning a security vulnerability into a secure design feature.
2Strength
If a safe is made with thick steel and heavy construction for security, then resistance to unauthorized access is improved, but the safe becomes difficult to install in limited spaces and may require attachment to larger structures
Solution Approach 1:
The patent addresses the space constraint problem by changing the door's movement from a two-dimensional swing (requiring external clearance) to a three-dimensional rotation within the safe's internal volume. This dimensional change allows the door to open without requiring external space, enabling installation in tight locations such as between bed components.
3Weight of moving object
If a safe is made small and lightweight for portability, then ease of movement is improved, but the safe becomes easy to remove by unauthorized persons
Solution Approach 1:
The patent segments the attachment system into two parts: a barbed plate that attaches to the box spring and a corresponding mounting structure on the safe. This segmentation allows the safe to be securely anchored to a larger structure (bed) without requiring the safe itself to be heavy, maintaining portability while preventing unauthorized removal.
4Ease of operation
If a conventional hinged door safe is used, then access is provided, but there isn't enough room for the door to swing open when the safe is attached to a bed frame between bed and furniture or wall
Solution Approach 1:
The patent inverts the door opening direction from outward swing to inward rotation. This inversion allows the door to open within the confines of the safe body, eliminating the need for external swing space and enabling installation in locations where the safe is positioned between the bed and furniture or walls.
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 ensures secure storage and quick, quiet access to valuables while deterring unauthorized removal, particularly from children and casual intruders, by utilizing a rotatable door mechanism and barbed plate attachment, enhancing both security and ease of access.
Implementation Method 1
An energy storage mechanism is interfaced between the safe body and the door. Energy is stored in the energy storing mechanism when the door is rotated into the first position of rotation and, upon enabling access by the locking mechanism, the locking mechanism disengages between the door from the safe body, and the energy storing mechanism releases the energy causing the door to rotate into the second position of rotation.
Data Source
AI summary
A safe includes a body that has an opening for receiving and holding an object. A door is rotatably interfaced to the body by, for example, a series of pins, whereas the door obstructs the opening in a first position of rotation, and the door provides access to the body of the safe through the opening when the door is in a second position of rotation. A locking mechanism engages between the door and the body when the door is rotated to the first position of rotation thereby holding the door in the first position of rotation until the locking mechanism is released and, upon releasing by the locking mechanism, the door is free to rotate towards the second position of rotation.
