Revolving-Door Safe With Barbed Mounting for Quiet Fast Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional secure storage devices for valuables, such as safes and lock boxes, face issues like pry-open vulnerabilities, space constraints for door opening, and difficulty in quick and silent access, especially when attached to smaller objects like bed frames, and are not secure against removal by unauthorized individuals, including children.
Innovation Solution
A safe with a revolving door and a locking system that allows for quick access using a code, combination, or biometric input, which is noise-dampened and securely attached to larger objects via a barbed plate to prevent removal, featuring a spring-loaded mechanism for easy operation and silent operation, and can be interfaced with bedding systems to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional hinged door is used in a safe, then the door can provide access to contents, but the door requires sufficient clearance space to swing open which is not available in tight confinements
Solution Approach 1:
The patent inverts the conventional door operation by making the door rotate on its axis rather than swing on hinges. The door rotates within a recess in the safe body, reversing the traditional hinge-based opening mechanism and eliminating the need for external clearance space.
Solution Approach 2:
The door movement transitions from a two-dimensional swing arc (requiring lateral clearance) to a three-dimensional rotation within a recess. This dimensional change allows the door to open without requiring external space, as the rotation occurs within the safe's own structure.
2Ease of operation
If a conventional hinged door is used in a safe, then the door can be opened for access, but the door may be pried open by inserting a lever between the box and door
Solution Approach 1:
By inverting the door mechanism from a hinged design to a rotating door within a recess, the patent eliminates the gap between door and body that prying tools exploit. The door rotates on an axis within the recess rather than swinging outward on external hinges.
Solution Approach 2:
The door is nested within a recess in the safe body, with the door's outer surface fitting within the recess boundaries when closed. This nesting arrangement prevents prying tools from being inserted between the door and body, as the door is contained within the recess structure.
3Reliability
If a heavy thick steel safe is used, then security against unauthorized access is improved, but the safe becomes difficult to relocate or attach to larger objects
Solution Approach 1:
The safe is segmented into modular components: a secure box body with locking mechanism, a separate attachment plate with mounting holes, and a rotating door assembly. This segmentation allows the safe to maintain its security structure while providing flexible attachment options to various surfaces and objects.
Solution Approach 2:
The attachment plate provides universal mounting capability with multiple hole patterns that can accommodate different attachment scenarios - whether mounting to a bed frame, wall, or other structure. This multi-functionality allows the same safe design to be securely attached in various locations without requiring custom heavy construction.
4Adaptability or versatility
If the safe is made small and light for easy placement, then adaptability is improved, but the safe becomes easy to remove or steal
Solution Approach 1:
The barbed plate attachment mechanism applies preliminary anti-action by creating mechanical resistance against removal forces. The barbs on the plate engage with the mounting surface in a direction that prevents easy detachment, requiring significant force or destruction to remove the safe from its mounted position.
Solution Approach 2:
The attachment system uses a composite structure combining the safe body, attachment plate, and barbed elements to create a unified assembly that is difficult to remove. The combination of these components provides both the light weight needed for easy placement and the resistance to removal needed for security.
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 safe provides enhanced security by allowing rapid and quiet access to contents, reducing the risk of pry-open attacks and removal, while the barbed plate attachment makes it difficult for children and most adults to relocate, thereby enhancing protection against theft and unauthorized access.
Implementation Method 1
a barbed plate that readily inserts between a box spring and a mattress, but due to the barbs, is difficult to remove without lifting the mattress from the box spring
Implementation Method 2
sound dampening devices are provided to provide a quiet retraction of the revolving door, so as to not alert an intruder
Data Source
AI summary
An application for a safe or strong box attaches to a larger, heavy object and provides improved security to its contents from unwanted removal. The safe or strong box has a revolving door that, when a proper code/combination/biometric is provided, rotatably opens to expose the contents. In one embodiment, the safe/strong box interfaces to, for example, a bedding system using a barbed plate that readily inserts between a box spring and a mattress, but due to the barbs, is difficult to remove without lifting the mattress from the box spring making it at least difficult to remove by, for example, children in the home. In some embodiments, sound dampening devices are provided to provide a quiet retraction of the revolving door, so as to not alert an intruder when the occupant is retrieving a weapon such as a pistol.
