Slide Safe Retractable Door Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safes with outward-opening doors and externally-mounted hinges pose security risks and space constraints, particularly in compact settings like homes and offices, as they can be mechanically compromised and require additional space.
Innovation Solution
A slide safe with a retractable door mechanism, featuring a motor-driven lead screw and flexible linkage system within the safe encasement, allowing the door to slide inwards without external hinges, powered by a control panel and rechargeable battery, and constructed from metallic and reinforced plastic materials for enhanced security and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional safes use externally-mounted hinges for door opening, then the door can be mechanically opened, but the security is compromised and additional space is required
Solution Approach 1:
The patent removes the traditional external hinge mechanism from the safe door system. Instead of having hinges mounted on the exterior, the invention extracts the rotational function and replaces it with a sliding mechanism that moves horizontally within the safe enclosure, eliminating the vulnerable external hinge components
Solution Approach 2:
The patent introduces a horizontal sliding mechanism as an intermediary between the door and the safe body. This sliding component allows the door to move open and closed without requiring external hinges, serving as a mediating element that provides the necessary motion while maintaining security and compactness
2Ease of operation
If the safe door opens outward, then the door can be easily opened, but additional space is required for door swing
Solution Approach 1:
Instead of the door opening outward in the traditional manner, the patent inverts the opening direction by having the door slide horizontally inward or along the face of the safe. This reversal of the opening mechanism eliminates the need for additional swing space while maintaining operational ease
Solution Approach 2:
The patent changes the door opening motion from a rotational movement in a vertical plane (traditional hinge operation) to a horizontal sliding movement along the face of the safe. This dimensional change allows the door to open without requiring additional space behind or beside the safe
3Strength
If external hinges are mounted on the safe, then the door can be attached securely, but the hinges become vulnerable to mechanical compromise
Solution Approach 1:
The patent removes the external hinge components that are vulnerable to mechanical compromise. By extracting these vulnerable elements and replacing them with an internal sliding mechanism, the design eliminates the specific vulnerability point while maintaining door attachment strength through alternative means
4Adaptability or versatility
If a traditional hinge system is used, then the door can rotate open, but the mechanism requires external mounting and additional space
Solution Approach 1:
The patent extracts the external hinge mechanism and its associated mounting requirements. By removing the need for external hinge attachment, the design simplifies the overall mechanism and increases placement flexibility, allowing the safe to be installed in locations where external mounting would be problematic

Function Achieved in This Case
The solution provides a secure, compact, and space-efficient safe that prevents mechanical compromise of hinges and allows for inward sliding doors, enhancing security and flexibility in placement options while maintaining robust construction.
Implementation Method 1
a motor positioned within the safe encasement, the motor mechanically connected to a lead screw having an axial rotational axis and driving a coupling
Implementation Method 2
a linkage positioned within the safe encasement, the linkage having a first end mechanically connected to the coupling and a second end mechanically connected to the retractable door; wherein the linkage is maintained in a conduit and the linkage is configured to flex as it translates within the conduit
