Solution Overview

Problem

Conventional secure storage units for firearms often obscure them from view, requiring salesperson assistance for customer inspection, while unsecured displays lack adequate security, as breaking a single lock can access all firearms.

Innovation Solution

A firearm holder assembly with a trigger peg and plunger lock system that secures firearms through the trigger guard, combined with a cable assembly using a securing bracket and cable, providing both visibility and enhanced security without obscuring the firearm.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional gun safe is used to secure firearms, then security is improved, but the firearms are obscured from view requiring salesperson assistance

Engineering Contradiction:
ImprovesecurityVSAvoidvisibility of firearms
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The system divides the security function into individual firearm-level locking mechanisms rather than a single cabinet lock. Each firearm is secured independently by its own trigger peg and lock plate assembly, allowing selective security while maintaining visibility of the entire collection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The trigger peg acts as an intermediary element that bridges the firearm's trigger guard and the holder body. This mediator component enables security through the trigger guard without obscuring the firearm's visual display, as the locking mechanism is positioned behind or alongside the visible firearm.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a single lock is used on display cabinet doors, then ease of operation is improved, but security deteriorates as breaking one lock provides access to all firearms

Engineering Contradiction:
Improvesimplicity of lockingVSAvoidsecurity against theft
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The security system is segmented into multiple independent locking units, one for each firearm. Each firearm requires its own trigger peg insertion and lock plate engagement, so that compromising one lock does not provide access to other firearms. This segmentation maintains operational simplicity while dramatically improving security.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes the security parameter from a single-point lock to a distributed multi-point locking system. By requiring multiple independent locking actions (one per firearm), the system increases the effort required for theft while maintaining ease of legitimate operation through the simple trigger peg insertion process.

Inventive Principle:
Principle #35Parameter changes

3Loss of information

If firearms are displayed without security measures, then visibility and customer access are improved, but unauthorized handling becomes possible

Engineering Contradiction:
ImprovevisibilityVSAvoidunauthorized handling
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The trigger peg serves as an intermediary security element that passes through the trigger guard without interfering with the firearm's visual display. This mediator enables security control while maintaining full visibility of the firearm for customer inspection.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The locking mechanism utilizes the firearm's own trigger guard structure as part of the security system. The trigger peg inserts through the existing trigger guard, making the firearm's own anatomy serve the dual purpose of operation and security without requiring additional obscuring components.

Inventive Principle:
Principle #25Self-service

AI summary

An assembly is configured for use with a firearm having a trigger guard. The assembly includes a firearm holder comprising a body and a trigger peg. The body includes an internal channel, a plunger lock, and a lock plate comprising a first interlock surface. The trigger peg includes a stem and a trigger flange. The stem is configured for insertion through the trigger guard and into the internal channel, the stem including a second interlock surface configured to mate with the first interlock surface. The trigger flange is sized to not pass through the trigger guard. A method of securing a firearm having a trigger guard is described. The method includes positioning the trigger guard at a body of a firearm holder, inserting a stem of a trigger peg through the trigger guard and into the body of the firearm holder, and locking the trigger peg to the body.
