Biometric Firearm Chamber Lock via Ejection Port
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearm safety devices, such as cable locks, gun safes, and trigger locks, fail to provide a balance between security and accessibility, often being expensive, difficult to transport, or ineffective in preventing unauthorized use.
Innovation Solution
A biometric electro-mechanical locking system integrated firearm safety device that securely locks firearms by engaging with the ejection port and uses a biometric sensor for quick access, along with a mechanical backup for situations without power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cable locks are used, then affordability is improved, but security deteriorates
Solution Approach 1:
The patent replaces traditional mechanical locking systems (cable locks, trigger locks) with a biometric authentication system using fingerprint sensors and electronic control. This substitution enables higher security through unique biometric identification while maintaining affordability by eliminating complex mechanical key systems and expensive safe structures.
2Reliability
If gun safes are used, then security is improved, but transportability deteriorates
Solution Approach 1:
The patent divides the firearm into separable components (upper receiver, lower receiver) that can be independently secured. The locking mechanism attaches to the upper receiver and secures it to the lower receiver, creating a segmented security system that is much lighter and more portable than traditional gun safes while maintaining security through biometric authentication.
3Reliability
If traditional locks are used, then security is improved, but accessibility deteriorates
Solution Approach 1:
The patent replaces mechanical key-based or combination-based locking systems with a biometric fingerprint authentication system. This enables rapid access for authorized users through simple fingerprint placement, eliminating the need to search for keys or remember combinations, while maintaining high security through unique biometric identification.
4Ease of operation
If trigger locks are used, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The patent extracts the locking mechanism from the trigger area and relocates it to the upper receiver/ejection port area. This prevents disassembly of the firearm and bypassing of the lock, as the locking mechanism secures critical structural components rather than just the trigger, thereby improving security while maintaining ease of operation through biometric authentication.
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 device provides high security, quick access, and is easily transportable, requiring no firearm modification for installation, while maintaining affordability and preventing unauthorized use.
Implementation Method 1
The firearm lock uses an electrical biometric sensor that can be used to quickly unlock the firearm lock from the firearm
Implementation Method 2
The deadbolt can be retracted by a motor that pulls the deadbolt via a gear and rack or via a cam mechanism
Implementation Method 3
The deadbolt is otherwise retained in the locked position by a spring, having a high ratio of spring force to deadbolt mass

AI summary
The biometric firearm chamber lock is a biometric electro-mechanical locking system integrated firearm safety device. The device safely locks firearms by securing the firearm lock into the firearm chamber through the ejection port to prevent rounds from being fired. An electrical biometric sensor quickly unlocks the firearm lock from the firearm. A mechanical backup unlock mechanism is used if a replacement battery is unavailable or if the electrical components fail and cannot be used to unlock the firearm lock. The firearm lock is an independent structure requiring no installation process.
