Firearm Magazine RFID Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm locks do not securely prevent unauthorized or unintentional use, especially when the firearm is loaded, as they require manual unlocking and reloading, and may not prevent trigger manipulation after loading.
Innovation Solution
A firearm locking system that uses a radio-frequency identification (RFID) reader to detect an authorized wearable device, enabling the trigger bar to be automatically unlocked when the authorized user is present, employing a double arm arrangement and electromagnet to physically block or allow trigger bar movement based on RFID input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional trigger locks are used to prevent unauthorized firearm use, then firearm security is improved, but user convenience deteriorates due to manual unlocking and reloading requirements
Solution Approach 1:
The patent replaces conventional mechanical trigger locks with an automated electromagnetic locking system. The electromagnet (component 112) replaces manual mechanical locking mechanisms, automatically engaging and disengaging based on RFID authentication. This substitution eliminates the need for manual unlocking and reloading operations, resolving the contradiction between security and ease of operation.
Solution Approach 2:
The system performs locking and unlocking operations automatically without requiring user intervention. When an authorized user presents their RFID card, the system self-services by detecting the card, authenticating the user, and automatically disengaging the locking mechanism. This self-service capability improves ease of operation while maintaining security, as the system handles all locking/unlocking actions autonomously.
2Reliability
If conventional trigger locks are used on loaded firearms, then unauthorized use is prevented, but readiness for operation is reduced due to loading delays
Solution Approach 1:
The system performs preliminary authentication and locking/dislocking actions before the user needs to operate the firearm. The RFID authentication occurs in advance, and the locking mechanism is pre-positioned in the appropriate state (locked or unlocked) based on authentication results. This eliminates waiting time for loading operations, as the system is already prepared in the correct state before the user needs to fire.
Solution Approach 2:
The electromagnetic locking system replaces manual mechanical locking that required time-consuming loading operations. The electromagnet can engage and disengage rapidly through electrical control, eliminating the mechanical delays associated with manual loading and cocking operations, thus reducing readiness time while maintaining security.
3Device complexity
If manual trigger locks are used, then simple construction is maintained, but automation for authorized user detection is lost
Solution Approach 1:
The patent introduces electromagnetic and electronic components (RFID reader, electromagnet, control unit) to replace purely mechanical locking systems. While this increases device complexity, it enables automatic detection of authorized users through RFID technology and automated locking/unlocking operations. The electromagnetic system provides precise control and automation capabilities that mechanical systems cannot achieve, resolving the contradiction between simplicity and automation.
Solution Approach 2:
The RFID card acts as an intermediary between the user and the locking system. Instead of direct mechanical interaction, the user presents the RFID card, which communicates authentication information to the reader. This intermediary enables automated user detection and authentication, allowing the system to automatically determine whether to lock or unlock without complex mechanical recognition systems.
Applied Scientific Principles

AI summary
A magazine for a firearm is described. The magazine may include a magazine housing comprising a recess at a front wall of a magazine housing top portion facing a trigger bar of the firearm. The magazine may further include a locking unit configured to move between a locked position and an unlocked position. The magazine may further include a radio-frequency identification (RFID) reader disposed in the magazine housing. The RFID reader is configured to detect presence of a wearable device in proximity to the trigger bar. The magazine may further include a control unit configured to control locking unit movement based on inputs from the RFID reader. The control unit may be configured to move the locking unit from the locked position to the unlocked position when the RFID reader detects presence of the wearable device in proximity to the trigger bar.
