Dual-Lock Firearm Trigger Lock with RFID Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm safety devices, such as trigger locks, often require a key for unlocking and can be cumbersome, especially in emergency situations where quick access is needed, and they may not accommodate both handguns and long guns discreetly.
Innovation Solution
A dual-lock configuration trigger lock that combines mechanical and electronic locking mechanisms, using RFID technology for remote electronic actuation, allowing authorized users to unlock the device with an RFID tag, and a mechanical key lock as a backup, providing secure and convenient access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical key lock is used, then the device provides secure storage, but it requires time to find and use the key in emergency situations
Solution Approach 1:
The patent replaces the purely mechanical key lock system with an electronic RFID-based locking mechanism. The RFID reader wirelessly communicates with the RFID tag to automatically unlock the trigger guard, eliminating the need for physical key manipulation and significantly reducing access time while maintaining security through electronic authentication.
Solution Approach 2:
The patent introduces an electronic control system as an intermediary between the user and the mechanical locking mechanism. The microcontroller processes RFID signals and controls the solenoid or motor actuator, creating a smart interface that enables rapid electronic unlocking while preserving the underlying mechanical structure for reliability.
2Device complexity
If a purely mechanical lock is used, then the structure is simple, but it lacks multiple opening modes for different situations
Solution Approach 1:
The patent implements a dual-mode locking system that can operate in both electronic RFID mode and mechanical key mode. This allows the device to adapt to different situations: rapid electronic access for authorized users and manual key access as a backup or for situations where electronics are unavailable, thereby increasing versatility without significantly complicating the overall structure.
3Loss of time
If an electronic lock with RFID technology is used, then quick access is enabled, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical key manipulation systems with a simpler electronic RFID authentication system. The wireless communication between RFID reader and tag eliminates the need for physical key insertion, turning, and removal, reducing access time while the electronic components actually simplify the overall interaction complexity compared to traditional mechanical systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The dual-lock configuration ensures secure storage while enabling quick and convenient access to firearms, accommodating various gun types and sizes, and reducing the risk of being unable to find a key during emergencies.
Implementation Method 1
The locking system utilizes an electronic actuator, such as RFID technology, to allow authorized users to open the trigger lock by simply moving an RFID chip into proximity with an interrogator in the trigger lock.
Data Source
AI summary
A firearm storage safety device, such as a trigger lock, for use on a firearm to make the trigger inaccessible. The lock has both a mechanical means and an electronic means to effect unlocking of the device. The electronic means includes a motor start device to effect operation of the electronic means components. Both unlocking means operate a common latching assembly.
