RFID Trigger Lock for Rapid Firearm Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm safety technologies do not provide rapid and stress-free access to secured firearms during emergencies, often requiring complex procedures and may be vulnerable to tampering or unauthorized access.
Innovation Solution
A Rapid Access Trigger Lock System that uses a two-piece design with a radio-frequency identification (RFID) mechanism, allowing secure attachment to a firearm and enabling rapid unlocking with a single-point contact using a wearable access key, incorporating a microprocessor for authentication and a servo motor for locking and unlocking, with features for battery conservation and area unlock signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex authentication procedures are used to prevent unauthorized access, then security is improved, but access time increases and ease of operation deteriorates
Solution Approach 1:
The system performs authentication in advance by storing multiple pre-programmed user identifiers in memory. When a user presents their identification, the microprocessor quickly compares it against stored identifiers without requiring complex real-time verification procedures, enabling rapid access while maintaining security.
Solution Approach 2:
The patent replaces complex mechanical authentication mechanisms (such as physical keys, combination locks, or multi-step verification devices) with an electronic RFID-based system. The microprocessor electronically compares stored identifiers with presented identifiers, significantly reducing authentication time while maintaining or improving security reliability.
2Speed
If RFID authentication system is implemented for rapid access, then access speed is improved, but device complexity increases
Solution Approach 1:
The trigger lock device integrates multiple functions into a single unit: it combines the locking mechanism, RFID antenna, microprocessor, memory storage, and power management in one device. This multi-functionality allows the system to perform rapid RFID authentication and locking/unlocking operations without requiring separate devices, thereby managing complexity while achieving high access speed.
Solution Approach 2:
The system automatically performs authentication and locking/unlocking operations without requiring manual intervention beyond presenting the identification. The microprocessor autonomously compares identifiers, controls the servo motor, and manages the locking mechanism, reducing the need for complex user interactions and simplifying the overall system operation.
3Ease of operation
If microprocessor and servo motor are added for automated locking, then ease of operation is improved, but use of energy increases
Solution Approach 1:
The microprocessor is designed to enter sleep mode between operations and only activates when an RFID identification is detected or when authentication is required. This periodic operation pattern significantly reduces average power consumption while maintaining the ability to provide automated locking/unlocking functionality when needed, thus preserving ease of operation without excessive energy use.
Solution Approach 2:
The patent replaces manual mechanical operation (such as manually manipulating locks or switches) with automated electronic control via the microprocessor and servo motor. This substitution improves ease of operation by allowing users to simply present their identification for automatic authentication and locking, while the energy consumption is managed through efficient sleep-wake cycles of the electronic components.

AI summary
This invention relates to an apparatus and method for detecting user activation of a button disposed on a trigger lock, communicating with a token located within a proximity of the trigger lock in response to the detection, receiving a user identifier from the token during the communication, determining whether the received user identifier is valid, and unlocking the trigger lock if the user identifier is determined to be valid. Provided that the token is located within the proximity and is valid, the user is only required to make a single contact with the trigger lock to unlock the trigger lock. Unauthorized access to the trigger of a firearm is thereby prevented while permitting an authorized user to quickly use the firearm.
