Solution Overview

Problem

Conventional firearm locks in vehicles, particularly in passenger compartments, fail to adequately secure rifles and shotguns from unauthorized access, tampering, or damage, especially when law enforcement officers need quick access while transporting prisoners.

Innovation Solution

A firearm lock shroud comprising side members that cover the trigger, take-down pin, and magazine areas, with an adjustable anti-lift bracket and mounting system to prevent unauthorized access and secure the firearm in place.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional firearm lock is used in a vehicle rack, then the firearm is secured from theft, but the firearm remains vulnerable to tampering, damage, or unauthorized access to critical components

Engineering Contradiction:

Improvefirearm securityVSAvoidtampering and unauthorized access

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The shroud is a nested structure that encloses the firearm within an additional protective layer. The first and second side members form a protective enclosure that contains the firearm, creating a nested configuration where the shroud surrounds the locked firearm to prevent access to critical components.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The shroud acts as an intermediary protective barrier between the firearm and potential threats. This intermediate structure prevents direct contact with the trigger, magazine, and other critical components, adding a layer of security without interfering with the primary lock mechanism.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of time

If the firearm is locked in a rack in the passenger compartment for quick access, then response time is reduced, but the firearm is exposed to unauthorized access when prisoners are transported nearby

Engineering Contradiction:

Improveaccess timeVSAvoidsecurity against unauthorized access

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The security system is segmented into multiple independent protective layers: the primary lock mechanism and the secondary shroud enclosure. This segmentation allows the firearm to remain quickly accessible while adding an independent layer of security that must be breached separately, addressing both speed and security requirements.

Inventive Principle:

Principle #1Segmentation

3Reliability

If the shroud covers the trigger, take-down pin, and magazine areas, then unauthorized access is prevented, but the structure becomes more complex

Engineering Contradiction:

Improveprotection of critical componentsVSAvoidshroud structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The shroud structure performs multiple functions simultaneously: it covers the trigger area, conceals the magazine insertion area, and protects the take-down pin location. This multi-functionality allows comprehensive protection without proportionally increasing structural complexity, as a single enclosure provides multiple security benefits.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A firearm lock shroud for a firearm lock comprises first and second side members. The first side member is positioned adjacent the firearm lock. The second side member is positioned adjacent the firearm lock and spaced apart from the first side member. The first and second side members define a firearm receiving space therebetween for receiving a firearm. The first and second side members extend over an area to cover at least a trigger area of a firearm received in the firearm receiving space and locked by the firearm lock to prevent unauthorized access to the trigger area. The side members can optionally extend to cover a magazine area and/or a take-down pin area of the firearm.
