Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gun locks are prone to key loss, deformation, or breakage, and are difficult to operate in emergency situations or dark environments, requiring complex unlocking procedures that hinder authorized use of firearms.
Innovation Solution
A keyless electronic gun lock system that uses a casing with a longitudinally displaceable extension rod and a locking component, driven by a powered driver, which can be unlocked via secure password access, allowing for quick and secure access to firearms without restraining the firearm's moving parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional mechanical gun lock using a key is used, then the firearm can be locked to prevent unauthorized use, but the key is prone to deformation, breakage, or loss, and the unlocking operation becomes complex and time-consuming in emergency situations
Solution Approach 1:
The patent replaces the conventional mechanical key-based locking system with an electronic control system. The electronic gun lock uses an electronic controller to actuate the locking component, eliminating the need for physical keys. This substitution resolves the contradiction by providing reliable electronic control while enabling simple operation through electronic interfaces such as buttons or biometric authentication.
Solution Approach 2:
The patent introduces an electronic controller as an intermediary between the user and the locking mechanism. The controller receives input from various interfaces (buttons, sensors, biometric devices) and translates them into actuation signals for the locking component. This intermediary layer enables diverse and simple unlocking methods while maintaining secure and reliable locking functionality.
2Reliability
If a conventional mechanical gun lock is used, then the firearm can be secured, but the unlocking operation requires removal of an unlocking device which is complicated and time-consuming
Solution Approach 1:
The patent implements preliminary action by pre-programming multiple unlocking sequences and modes in the electronic controller before an emergency situation occurs. The system can be configured with quick-unlock modes, biometric authentication, or coded sequences that are ready to execute instantly. This eliminates the time-consuming manual manipulation required by conventional locks while maintaining security through pre-established authentication protocols.
Solution Approach 2:
The patent applies dynamics by enabling the locking component to be actuated rapidly through electronic control signals. The electronic system can transition between locked and unlocked states quickly by electrically actuating the locking component, eliminating the slow mechanical manipulation of conventional unlocking devices. The system adapts its response time based on the unlocking method selected, providing both security and speed.
3Reliability
If a mechanical gun lock is used, then the firearm can be locked, but it is not easy to operate in a dark environment
Solution Approach 1:
The patent replaces mechanical key insertion and manipulation with electronic input methods that do not rely on visual guidance. The electronic controller can accept input through tactile buttons with Braille markings, audio feedback, biometric sensors, or wireless communication. This substitution eliminates the need to visually locate and manipulate mechanical components in dark environments while maintaining reliable locking functionality.
Solution Approach 2:
The patent implements self-service features such as biometric authentication (fingerprint, facial recognition) or automatic proximity detection that enable unlocking without manual intervention or visual input. The system serves itself by automatically verifying the user's identity or authorization status and actuating the locking component accordingly, eliminating the need for the user to manually operate controls in dark or challenging environments.
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 system provides secure and simple unlocking of firearms, preventing unauthorized use and facilitating rapid access in emergency situations, even in dark environments, without the need for physical keys or complex unlocking procedures.
Implementation Method 1
A powered driver is coupled to the extension rod for selectively driving the displacement thereof responsive to user activation

AI summary
A system for keyless locking of a firearm against discharge is provided, which includes a casing configured for removable insert into a barrel of the firearm, and an extension rod disposed in longitudinally displaceable manner therein. The extension rod is provided with first and second ends and an intermediate portion extending longitudinally therebetween. A locking component supported by the casing is displaceable responsive to the extension rod between locked and unlocked positions. A powered driver coupled to the extension rod for selectively drives the displacement thereof responsive to user activation. The locking component in the locked position protrudes transversely beyond the casing for retentively engaging an inner surface of the firearm to prevent removal of the casing from its barrel, and in the unlocked position is retracted to maintain clearance from the inner surface of the firearm to permit removal of the casing from the barrel of the firearm.
