Solution Overview

Problem

Conventional gun safes are bulky, consume excessive space, have vulnerable external hinges that can be compromised by thieves, and do not optimize the storage and access of firearms within their interior.

Innovation Solution

A secure enclosure with a cylindrical design featuring a door that shifts inwardly and outwardly without external hinges, utilizing a rotating member for dual unlocking and door translation, and an automatic mechanical actuator for secure and compact storage and access, optimizing gun placement and security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If an outwardly swinging door is used with an external hinge, then the door can be easily opened and closed, but the safe becomes bulky and the external hinge can be destroyed by thieves to gain access

Engineering Contradiction:
Improvedoor operationVSAvoidsecurity against theft
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent removes the external hinge from the door assembly and integrates the hinge mechanism inside the safe housing. This extraction of the vulnerable external hinge eliminates the weakness that thieves could exploit while maintaining the door's functionality through an internal hinge mechanism that is much more difficult to compromise.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The hinge mechanism is nested within the door assembly itself, with the hinge pins and mounting structures integrated into the door's internal structure. This nesting eliminates the need for external hinges and provides a more secure configuration where the hinge components are protected within the door's own framework.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If a box-shaped safe with outwardly swinging door is used, then the door provides easy access, but the safe consumes excessive space and cannot be placed in small closets

Engineering Contradiction:
Improveaccess to interiorVSAvoidspace occupied
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent employs a cylindrical door design that curves to match the cylindrical housing shape. This curved geometry allows the door to swing inward along the cylindrical surface rather than requiring the flat, bulky swing path of a traditional box-shaped safe, significantly reducing the space required for operation and enabling placement in compact locations.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The door movement is transitioned from a horizontal outward swing (requiring external space) to a vertical or radial inward movement along the cylindrical axis. This dimensional change allows the door to open without protruding outward, eliminating the need for excessive external clearance and enabling compact installation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Quantity of substance

If conventional gun storage arrangement is used, then guns can be stored, but the number of guns that can be stored and readily accessed is not optimized

Engineering Contradiction:
Improvenumber of guns storedVSAvoidaccess to guns
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The patent implements a rotatable platform or carousel mechanism within the safe interior that can be rotated to bring different guns to the door opening. This dynamic rotation system allows multiple guns to be stored in a compact arrangement while enabling easy access to any gun by simply rotating the platform, significantly increasing both storage capacity and accessibility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The gun storage arrangement transitions from a static linear or wall-mounted configuration to a three-dimensional rotatable platform. This dimensional change allows guns to be arranged in a compact circular pattern around a central axis, maximizing the number of guns that can be stored within the safe's interior volume while maintaining easy access through rotation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A safe having a support assembly disposed in the interior of the safe. The door of the safe is coupled to the support assembly and is easily shiftable between a closed position wherein the door is received in an opening of the safe and an open position wherein the door is removed from the opening in the safe and disposed in the interior of the safe.
