Solution Overview

Problem

Pistol collectors face challenges in conveniently and securely storing large numbers of pistols, with existing safe designs failing to provide adequate access and storage options.

Innovation Solution

A gun safe with a rotating inner shelving system featuring vertically aligned shelves with differently sized cutouts, allowing for efficient storage and access of various handgun sizes, and optionally including fixed shelves for long guns, enhancing storage capacity within a compact space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If traditional fixed shelving is used in safes, then structural simplicity is maintained, but storage capacity and accessibility for large numbers of pistols are insufficient

Engineering Contradiction:
Improvestorage capacity for pistolsVSAvoidshelving system complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by implementing a rotating shelving system where shelves can rotate about a central axis. This dynamic mechanism allows multiple shelves to be accessed by rotating the assembly, significantly increasing storage capacity and accessibility compared to fixed shelving, while maintaining a compact footprint within the safe.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent utilizes the another dimension principle by arranging shelves in a vertical array that rotates about a central axis, effectively using the rotational dimension to access multiple storage levels. This transforms a two-dimensional storage problem into a three-dimensional rotating structure, maximizing space utilization within the safe's interior volume.

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

2Adaptability or versatility

If shelves with uniform cutouts are used, then manufacturing simplicity is maintained, but adaptability to different handgun sizes is limited

Engineering Contradiction:
Improveaccommodation of various handgun sizesVSAvoidshelf fabrication complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies the local quality principle by incorporating differently sized cutouts in specific locations on each shelf to accommodate different handgun sizes. Each cutout is locally optimized for specific firearm dimensions, allowing the same shelf structure to universally support various handgun types while maintaining manufacturing feasibility through standardized shelf components.

Inventive Principle:
Principle #3Local quality

3Productivity

If multiple separate shelving systems are used for handguns and long guns, then storage versatility is improved, but space utilization and access efficiency deteriorate

Engineering Contradiction:
Improveaccess efficiencyVSAvoidstorage versatility for different firearm types
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent applies the universality principle by designing a rotating shelving system that can accommodate both handguns and long guns through appropriately configured cutouts and shelf dimensions. The same rotating mechanism serves multiple functions by storing different firearm types, improving access efficiency while maintaining storage versatility without requiring separate shelving systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A gun safe, according to various embodiments, comprises: (1) a secure housing defining an interior and an opening; (2) a door; and (3) a vertical array of shelves within the interior of the secure housing immediately adjacent a lateral portion of the opening. In various embodiments, each of the shelves defines a handgun support portion that comprises a cutout that is dimensioned to allow a portion of a handgun to extend through the cutout as the handgun is supported on opposite sides of the handgun by the shelf. In particular embodiments, the gun safe further comprises at least one shelf disposed within the interior of the secure housing that is configured to rotate about a central axis and defines one or more handgun support portions.
