Solution Overview

Problem

Conventional firearm locking mechanisms are externally mounted, prone to loss, incorrectly secured, and time-consuming to remove, failing to prevent unauthorized access and accidental discharge.

Innovation Solution

A rotating firearm grip with an integrated locking mechanism that includes a pivotally secured handgrip body, a firearm engagement member, and a locking mechanism with a push button and biometric authentication system, allowing secure transition between SAFE and FIRE positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If external locking mechanisms are used, then the firearm can be locked to prevent discharge, but the locking mechanism can become lost when removed and takes time to physically remove

Engineering Contradiction:

Improvefirearm locking reliabilityVSAvoidtime to remove lock

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The locking mechanism is merged with the firearm grip itself, making the grip body serve as both the handle and the locking device. The grip rotatably engages with the trigger assembly housing, integrating the locking function directly into the firearm structure rather than using separate external components.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The grip is divided into functional segments: the grip body that rotates, the trigger assembly housing that receives the trigger, and the authentication mechanism. This segmentation allows the locking and unlocking functions to be distributed across different components that work together.

Inventive Principle:

Principle #1Segmentation

2Reliability

If external locking mechanisms are used, then the firearm can be locked, but the mechanism may be incorrectly secured allowing unauthorized access

Engineering Contradiction:

Improvefirearm locking reliabilityVSAvoidcorrect locking operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The manual mechanical locking process is replaced with an automated authentication system. The biometric sensor and motorized actuator eliminate the need for users to manually manipulate locking components, reducing human error and ensuring consistent proper engagement.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs the locking action automatically after authentication. The motorized actuator self-actuates to rotate the grip into the locked position without requiring the user to manually position or secure any components.

Inventive Principle:

Principle #25Self-service

3Reliability

If the selector switch is used to prevent discharge, then inadvertent discharge is prevented, but unauthorized users can still fire by transitioning the switch

Engineering Contradiction:

Improveaccidental discharge preventionVSAvoidunauthorized access prevention

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The mechanical selector switch is replaced with a biometric authentication system. Instead of manually moving a switch between SAFE and FIRE positions, the system uses a biometric sensor to verify the user's identity and automatically actuate the grip rotation, combining accidental discharge prevention with unauthorized access prevention.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The biometric authentication system serves as an intermediary between the user and the firearm's firing mechanism. The authentication unit verifies the user's identity before allowing the motorized actuator to rotate the grip, creating a controlled access pathway that prevents both accidental and unauthorized discharge.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Adaptability or versatility

If an authentication system is added, then unauthorized access is prevented, but the device complexity increases

Engineering Contradiction:

Improveunauthorized access preventionVSAvoidlocking mechanism complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The grip body serves multiple functions: it is both the handle for holding the firearm and the locking mechanism that secures the trigger assembly. The rotation of the single grip component simultaneously performs the authentication verification and the physical locking action, reducing the need for separate dedicated components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A firearm grip with locking mechanism includes an elongated handgrip body having an elongated opening on the front side and a generally hollow interior space. A pair of doors are pivotally secured to the handgrip body to move between a closed position, and an open position. A firearm engagement body is pivotally secured along the top end of the handgrip body for attachment to a firearm receiver at a location adjacent to the trigger assembly. The handgrip body moves between a FIRE position where the handgrip body is positioned perpendicular to the engagement body, and a SAFE position where the handgrip body is positioned parallel to the engagement body and the firearm trigger assembly is located within the interior space of the handgrip body.
