Solution Overview

Problem

Typical gun security systems fail to accommodate extensions attached to weapons and do not fully support the weight of the weapon, often requiring additional structures like a butt plate for support.

Innovation Solution

A weapon security apparatus featuring C-shaped plates that apply pressure to the barrel, magazine tube, or receiver, with an over-center linkage for continuous pressure and adjustable distance between plates to accommodate different sizes, allowing for secure locking without additional support structures underneath.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If typical gun security systems are designed to fit closely around the weapon receiver, then the locking mechanism can effectively secure the weapon, but the system cannot accommodate extensions (e.g., side saddle) attached to the weapon

Engineering Contradiction:
Improvelocking effectivenessVSAvoidaccommodation of extensions
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The locking mechanism is divided into multiple independent plates (first plate, second plate, third plate) that can be positioned and adjusted separately. Each plate can be configured to accommodate different weapon types and extensions independently, allowing the system to maintain reliable locking while adapting to various weapon configurations including those with side saddles or other attachments.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If typical gun security systems use a compact design around the receiver, then the structure remains simple, but the system cannot fully support the weight of the weapon without additional structures like a butt plate

Engineering Contradiction:
Improvestructure simplicityVSAvoidweight support capability
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The plates are designed to perform multiple functions: they provide locking action, support weapon weight, and accommodate various weapon types and extensions. The first plate engages the barrel or magazine tube, the second plate engages the receiver, and the third plate supports the butt portion, allowing the system to support full weapon weight without requiring additional butt plates or support structures.

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

3Ease of manufacture

If the distance between plates is fixed, then the manufacturing is simpler, but the system cannot accommodate different sized weapons

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidaccommodation of different weapon sizes
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The distance between plates is made adjustable through movable plate configurations. The second plate can be positioned at different distances from the first plate, and the third plate can be positioned at different distances from the second plate, allowing the system to accommodate weapons of various lengths and sizes while maintaining a relatively simple manufacturing process using standard adjustment mechanisms.

Inventive Principle:
Principle #15Dynamics

AI summary

A firearm security apparatus may include a base assembly and a locking assembly having a first plate and a second plate. The second plate may be moveable between an open position and a closed position relative to the first plate. The first plate and the second plate may be configured to receive a weapon therebetween, where the first plate, the second plate, or both have a window defined therein to form a C-shape having a first member that engages the weapon above a grip and having a second member that engages the weapon below the grip when the second plate is in the closed position.
