Firearm Trigger Interlock with Biometric Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearm injuries and deaths are a significant public health problem due to unauthorized use, misuse during states of fear, anger, or mental distress, and the inability to track and monitor firearms effectively.
Innovation Solution
A firearm activation and monitoring system that utilizes biometric sensors to track and monitor a user's mental state, integrating with a trigger interlock mechanism to prevent unauthorized firing and notify third parties of firearm usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric sensors and monitoring systems are integrated into the firearm, then the ability to track and monitor user mental state and prevent unauthorized use is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions (biometric sensing, mental state monitoring, trigger interlock control, and user identification) into an integrated firearm safety system. The biometric sensors, microcontroller, and trigger interlock mechanism work as a unified system where the microcontroller coordinates between sensor inputs and trigger control outputs, reducing the need for separate independent systems.
Solution Approach 2:
The trigger interlock mechanism serves multiple functions: it prevents unauthorized firing when biometric authentication fails, blocks trigger operation during detected mental distress states, and coordinates with both biometric sensors and mental state monitors. This multi-functional approach consolidates several safety mechanisms into a single integrated component.
2Reliability
If trigger interlock is positioned directly behind the trigger, then the ability to prevent trigger movement is improved, but the ease of operation decreases
Solution Approach 1:
The trigger interlock is designed as a movable component that can shift between locked and unlocked positions. When the firearm is properly authenticated and safe to operate, the interlock moves to an offset position that allows trigger movement. This dynamic positioning maintains security when needed while enabling operation when authorized.
Solution Approach 2:
The trigger interlock acts as an intermediary mechanism between the trigger and the firing mechanism. It provides a controlled interface that can either permit or block trigger operation based on system conditions, serving as a mediating component that balances safety requirements with operational needs.

AI summary
A firearm activation and monitoring system which tracks, monitors, and automatically prevents a firearm from firing when a user is not in a suitable state of mind or is not an authorized user, as well as a method for activating and monitoring a firearm. The firearm activation and monitoring system generally comprises a firearm having a trigger and grip area, a plurality of biometric sensors located on the grip area which measure biometric data of a user, a trigger interlock, and a main microcontroller. The trigger interlock prevents the trigger from firing the firearm when the trigger interlock is in its normal or default position. To unlock the trigger, the user holds the grip area to activate the biometric sensors, and if the user is in an acceptable mental state, the main microcontroller will send an electrical signal to the trigger interlock, which unlocks the trigger and allows the user to pull the trigger of the firearm.
