Firearm Trigger-Locking Mechanism with Biometric Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearm safety measures fail to prevent accidental discharges during cleaning and do not deter unauthorized use, as they only address access control rather than providing comprehensive safety features.
Innovation Solution
Integration of a chipset with a wireless communication module, environmental sensors, and a biometric scanner into firearms to monitor and lock the trigger, record discharge data, and enable inductive charging, ensuring only authorized users can operate the firearm and providing situational data for investigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional trigger locks and firearm lockboxes are used, then access control is improved, but comprehensive safety during cleaning and disassembly is not achieved
Solution Approach 1:
The patent replaces mechanical trigger locks and lockboxes with an electronic monitoring system that uses sensors, microcontrollers, and software to detect firearm state and control trigger availability. The system substitutes mechanical safety mechanisms with electronic detection and control systems that can monitor cleaning activities and prevent accidental discharge through intelligent decision-making algorithms.
Solution Approach 2:
The firearm safety system performs self-monitoring through integrated sensors that automatically detect when the firearm is being cleaned, disassembled, or handled. The system autonomously determines whether to enable or disable trigger functionality based on detected conditions, eliminating the need for manual intervention or external lockbox mechanisms.
2Reliability
If biometric authentication systems are implemented, then unauthorized use is deterred, but the firearm cannot be used by law abiding citizens living with felons
Solution Approach 1:
The authentication system dynamically adjusts trigger availability based on real-time biometric identification. Instead of a static lockout approach, the system continuously monitors who is handling the firearm and enables trigger functionality only when an authorized person is detected. This dynamic control allows flexible access within residences while maintaining security against unauthorized use.
Solution Approach 2:
The system applies different authentication requirements and access levels to different individuals within the same residence. By identifying specific authorized users through biometrics, the system enables law-abiding citizens to access firearms in their home while preventing felons from using firearms, even when present in the same location. Each person receives localized access control based on their identity.
3Measurement precision
If complex lab work is used to identify shooter and discharge time, then accurate identification is achieved, but the process becomes expensive and tedious
Solution Approach 1:
The system performs preliminary data collection continuously, maintaining ready logs of biometric identifications, timestamps, and discharge conditions. When a discharge occurs, the information is already captured and stored, eliminating the need for post-incident lab analysis. The preliminary recording of all relevant data during normal operation enables immediate identification of shooter and discharge details.
Solution Approach 2:
The patent replaces complex laboratory analysis procedures with electronic sensing and digital recording systems. Biometric scanners, timestamps, and sensors automatically capture identification data, discharge timing, and environmental conditions, substituting manual lab work with automated electronic measurement and data storage systems that provide immediate results.

Data Source
AI summary
A method of monitoring and trigger-locking a firearm prevents unauthorized persons from firing the firearm. When a person picks up the firearm, a biometric scanner retrieves an unidentified biometric reading off of the person. The biometric scanner can be a palm-print reader and/or a fingerprint reader. If the unidentified biometric reading does not match an authorized user signature stored on a chipset of the firearm, and if the firearm has unlocked its trigger, then the firearm automatically locks its trigger. In addition, the firearm generates and broadcasts an unauthorized-use notification with a wireless communication module. If the unidentified biometric reading does match an authorized user signature stored on the chipset, and if the firearm has locked its trigger, then firearm automatically unlocks its trigger. The firearm also collects situational data from environmental sensors when the firearm discharges a round.
