Modular Weapon Lock with Pivotable Latch and Tamper-Evident Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weapon cabinets face issues such as difficulty in rearranging weapon layouts, susceptibility to tampering or damage, cumbersome locks, and complex or costly designs.
Innovation Solution
A modular weapon lock system integrated with a weapon rack and cabinet, featuring a latch pivotably coupled to a housing with adjustable arms and a pivot limit extension, allowing for secure and adjustable weapon storage with tamper-evident security fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional weapon locks are used, then security function is provided, but the locks are cumbersome and difficult to operate
Solution Approach 1:
The weapon lock system is divided into separate functional components: a latch assembly with pivotable arms for engagement, a separate locking mechanism with a key or combination lock, and a mounting system. This segmentation allows each component to be optimized independently, simplifying operation while maintaining security.
Solution Approach 2:
The locking function is extracted from the weapon itself and placed in a separate cabinet-mounted lock system. This eliminates the need for complex locks attached to or integrated with the weapon, making the weapon easier to handle while the cabinet provides the security function.
2Adaptability or versatility
If fixed weapon cabinet designs are used, then structural stability is provided, but rearrangement for different weapon layouts is difficult
Solution Approach 1:
The cabinet incorporates adjustable and reconfigurable elements such as movable shelves, adjustable weapon racks, and repositionable mounting plates that allow the internal layout to be dynamically changed to accommodate different weapon types and configurations while maintaining overall structural integrity.
Solution Approach 2:
The cabinet interior is segmented into modular components including separate racks for different weapon types, adjustable shelves, and independent mounting systems. This modular segmentation allows individual sections to be reconfigured without affecting the entire cabinet structure.
3Reliability
If traditional mounting methods are used, then weapons are secured, but tampering and damage are possible
Solution Approach 1:
Tamper-evident fasteners serve as an intermediary between the mounting system and the weapon rack, providing visible indication of tampering attempts without requiring complex electronic surveillance or alarm systems. The fasteners include features such as breakable seals, color-coded indicators, or one-way threading that clearly show when they have been disturbed.
4Reliability
If complex weapon lock designs are used, then security function is improved, but cost increases
Solution Approach 1:
The lock system incorporates self-latching mechanisms and automatic engagement features that eliminate the need for complex locking procedures or multiple locking components. The design uses simple, robust mechanisms such as spring-loaded latches and gravity-assisted engagement that are both secure and cost-effective to manufacture.

AI summary
A weapon lock includes a latch pivotably coupled to a housing about a latch pivot axis, and includes a base arm, receiver and retainer arms extending transversely away from the base arm, and a pivot limit extension extending longitudinally away from the base arm. A weapon rack is configured to carry the weapon lock and includes upper and lower plates with upper and lower arrays of mounting apertures and pivotably coupled to one another via a hinge. A weapon cabinet is configured to carry the weapon rack and includes an enclosure having a rear wall to which a mounting backplane of the weapon rack is fastened with tamper-evident security fasteners, and having sidewalls, top and bottom walls, and doors hingedly coupled to the sidewalls.
