Biometric Firearm Safety Lock with Hinged Trigger Guard
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved firearm safety devices that prevent accidental discharge by unauthorized individuals while allowing quick access for authorized users, as many firearms are kept loaded and unlocked, leading to injuries and fatalities, especially among children.
Innovation Solution
A firearm safety apparatus featuring locking arms connected by a hinge that surround the trigger guard, a locking mechanism to retain the arms in a closed position until an activation signal is received, and a biometric sensor or other authentication methods to allow authorized access, ensuring rapid deployment and prevention of unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a firearm is kept loaded and unlocked for quick access, then the speed of deployment is improved, but the safety against unauthorized access deteriorates
Solution Approach 1:
The trigger guard cover is designed to dynamically change its position between a closed state (covering the trigger for safety) and an open state (exposing the trigger for use). This dynamic mechanism allows the system to adapt its security level based on whether the firearm is in storage or being actively used, resolving the contradiction between safety and accessibility.
Solution Approach 2:
A locking mechanism acts as an intermediary between the trigger guard cover and the firearm trigger. This intermediary component controls access to the trigger by requiring authentication (such as a key, code, or biometric verification) before allowing the cover to open, thus maintaining security while enabling authorized quick access.
2Reliability
If a locking mechanism is added to prevent unauthorized access, then the safety against unauthorized access is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is segmented into distinct functional components: an authentication module (for verifying user identity), a locking actuator (for engaging/disengaging the lock), and a trigger guard cover (for physical protection). This segmentation allows each component to be optimized independently and simplifies the overall system by dividing complex functions into manageable parts.
Solution Approach 2:
The locking mechanism is designed with multi-functionality to handle various access control needs through a single integrated system. It can support multiple authentication methods (key-based, code-based, biometric), serve both as a security barrier and an access enabler, and work with different firearm configurations, thereby reducing the need for multiple separate security devices.
3Reliability
If a biometric sensor is incorporated for authentication, then the security authentication is improved, but the manufacturing precision and device complexity increase
Solution Approach 1:
The traditional mechanical key-based locking system is replaced with a biometric authentication system that uses biological characteristics (fingerprint, facial recognition, iris scan, etc.) for verification. This substitution enhances security by using inherently unique biological traits that are difficult to replicate, while the integration is designed to accommodate standard manufacturing processes through modular sensor placement.

AI summary
A firearm safety apparatus is provided that includes two or more locking arms or coverings connected by a hinge and configured to engage a trigger guard of a firearm, in a closed position preventing access to the trigger. A locking mechanism retains the arms in a closed position until opened by an activation signal. A firearm safety apparatus is also provided that includes a housing connected to a firearm. A trigger guard cover is slideably or hingably connected to the housing. A locking mechanism is coupled to the trigger guard cover to surround a trigger of the firearm until an activation signal is received. The locking mechanism exposes the trigger through a hinged or slide motion. The housing is amenable to inclusion of various tactical accessories such as a light source or a camera.
