Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm safety solutions, such as fingerprint detection, barrel locks, and RFID embedded hand grips, are not universally compatible and can be easily bypassed, posing risks to users, especially in civilian settings where unauthorized access to firearms can lead to accidents or misuse.
Innovation Solution
A self-locking slide mechanism activated by proximity detection, using a wrist-worn device and a printed circuit board, electromechanical mechanism, and spring-loaded slide, which blocks trigger access unless within a predetermined range, ensuring compatibility across various firearms and requiring intentional removal with a key.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fingerprint detection or barrel locks are used, then trigger access is controlled, but the device complexity increases and compatibility with various firearms is reduced
Solution Approach 1:
The patent replaces complex mechanical locking systems (fingerprint detectors, barrel locks) with a simpler electromechanical proximity-based system. The trigger lock uses a proximity sensor and electromagnetic field to detect the presence of a authorized device, automatically engaging or disengaging the trigger mechanism without requiring complex mechanical authentication processes.
Solution Approach 2:
The trigger lock device is designed with universal compatibility across multiple firearm models through a standardized interface that can attach to various trigger mechanisms. The system serves multiple functions: proximity detection, electromagnetic locking, and mechanical trigger engagement, all integrated into a single compact unit that works with different firearm types.
2Reliability
If RFID embedded hand grips are used, then trigger control is achieved, but the device can be easily bypassed and lasting safety is not provided
Solution Approach 1:
The system applies preliminary anti-action by continuously monitoring the proximity field and automatically re-engaging the trigger lock if the authorized device is removed or if unauthorized approaches are detected. The electromagnetic field creates a persistent barrier that must be intentionally disrupted, preventing casual bypass attempts and ensuring lasting safety.
Solution Approach 2:
The trigger lock incorporates feedback mechanisms through proximity sensors that continuously detect the presence of the authorized device. When the device is removed or the field is disrupted, the system receives feedback and automatically re-locks the trigger, creating a continuous loop of security verification that prevents bypass attempts.
3Ease of operation
If a proximity detection system is used, then ease of operation is improved, but the device complexity increases
Solution Approach 1:
The trigger lock system performs self-service through automatic proximity detection and electromagnetic locking without requiring manual user intervention. The system autonomously engages and disengages the trigger mechanism based on the presence or absence of the authorized device, eliminating the need for users to manually operate complex locking mechanisms while maintaining simplicity.

AI summary
The invention relates to an electronic device that is used to block the accessibility of a firearms Trigger. Wherein an electronic device is mounted on a rail or rail accessory and is locked in place using a lock and frame allowing the device to fit an array of firearms. The lock and frame are in place to stop easy removal unless the possessor has the key to remove them. The device its self uses a battery to operate and picks up or sends a broadcasted transmission within a programmed range by the use of a printed circuit board (PCB) capable of receiving or sending a broadcasted transmission. Once the transmission has been picked up or sent and received it activates the electronic devices locking mechanism in the form of a electromechanical mechanism causing it to shift and allows a slide placed in front of the trigger acting as a second trigger to move back and forth allowing the movement of the firearms trigger. The slide is moved back into its original position by the use of a spring driven mechanism. When the worn device or the electronic device is out of the programmed range, the electromechanical mechanism returns to its locked state stopping access to the trigger. Making the trigger locking device a beneficial reusable safety device.
