Biometric Rifle Safety Insert with Modular Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety devices for rifles lack effective and simple security mechanisms to prevent unauthorized use, as they are often complex and designed for pistols or revolvers, necessitating a solution tailored for rifles.
Innovation Solution
A safety device with a modular insert for the rifle magazine well, featuring a biometric sensor and actuating mechanism that adjusts locking elements between blocking and release positions, ensuring secure engagement within the magazine shaft and preventing unauthorized removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism is added to prevent unauthorized use of rifles, then security is improved, but device complexity increases
Solution Approach 1:
The safety device is segmented into distinct functional modules: a biometric sensor unit for authentication, a locking mechanism with movable blocking elements, and a magazine insert component. This modular segmentation allows each component to perform its specific function independently, simplifying the overall system design while maintaining high security through biometric verification before enabling magazine insertion or removal
Solution Approach 2:
The patent introduces an intermediary locking mechanism that acts as a mediator between the biometric authentication system and the magazine shaft. The locking elements serve as intermediaries that physically block or allow magazine insertion based on authentication results, creating a controlled interface that enhances security without requiring direct integration of complex systems
2Reliability
If a biometric sensor and actuating device are integrated into the magazine shaft, then unauthorized use is prevented, but ease of operation deteriorates
Solution Approach 1:
The biometric authentication is performed in advance before the magazine insertion or removal process begins. The locking elements are positioned in a blocking state by default, and only after successful biometric verification does the system transition to an unlocked state, allowing magazine operations. This preliminary authentication ensures security while maintaining intuitive operation for authorized users
Solution Approach 2:
The locking mechanism is designed to automatically transition between locked and unlocked states based on biometric authentication results, without requiring manual intervention. The actuating device automatically moves the blocking elements when authentication succeeds, and the system self-regulates magazine access based on the authenticated user's credentials, simplifying the user experience while maintaining security

AI summary
The safety device has a biometric sensor arranged on a portion of a gun and a positioning device coupled with the biometric sensor. A locking mechanism (2) for releasable shutoff of a store shaft or locking of a lock is actuated by the positioning device depending on the data determined by the biometric sensor. The biometric sensor and the positioning device are arranged on an insert (1) insertable in the gun.
