Solution Overview

Problem

Existing firearm safety systems either require excessive time to transition from a safe to a functional state or prevent authorized users from using the firearm due to malfunctioning user verification systems, limiting their effectiveness in emergency situations.

Innovation Solution

A safety system for firearms that includes an engagement member rotatable between unlock and lock positions, coupled with a lock mechanism and user interface, allowing quick transition to a functional state while maintaining a separation distance between the firing pin and primer, and enabling authorized user access through biometric or electronic verification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a secure container is used to store the firearm, then unauthorized access is prevented, but access time increases significantly

Engineering Contradiction:
Improvefirearm securityVSAvoidaccess time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system separates the firearm from the secure container, using only a locking apparatus attached to the firearm itself. This eliminates the need to open a container while maintaining security through the locking mechanism that prevents trigger actuation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking apparatus is extracted from a container-based system and applied directly to the firearm. The lock can be quickly engaged or disengaged without the time-consuming process of opening a secure container, while still providing reliable security.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If a locking apparatus is attached to the firearm, then unauthorized discharge is prevented, but transition to functional state takes too long

Engineering Contradiction:
Improvefirearm safetyVSAvoidtransition speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The locking apparatus uses a dynamic design where the trigger guard can be quickly moved between locked and unlocked positions. The spring mechanism enables rapid transition by automatically returning the trigger guard to its original position after being displaced, allowing fast engagement and disengagement without manual repositioning.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spring mechanism provides self-service by automatically returning the trigger guard to its locked position after disengagement. This eliminates the need for the user to manually reposition components during the transition process, significantly reducing the time required to move from safe to functional state.

Inventive Principle:
Principle #25Self-service

3Reliability

If user verification system is used, then authorized user confirmation is achieved, but system malfunction can prevent authorized access

Engineering Contradiction:
Improveuser verificationVSAvoidauthorized access
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system removes complex electronic user verification components and replaces them with a simple mechanical locking apparatus. This eliminates the risk of electronic malfunction while maintaining security, as the mechanical system has no moving parts that can fail electronically and requires only physical manipulation to engage or disengage.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Systems and methods are provided for the making safe of a firearm. A safety system includes a lock mechanism coupled to an engagement member and a user interface. The engagement member is movably coupled to the firearm and rotatable between an unlock position and a lock position. A contact face of the engagement member is in contact with an outer surface of a distal portion of a breechblock in the lock position and precludes a distal movement of the breechblock. The engagement member is configured to transition between the lock position and the unlock position while remaining movably coupled to the handgun. Movement of the engagement member from the lock position is restricted by the lock mechanism until disengaged via the user interface.
