Sliding Trigger Enclosure for Firearm Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm locking mechanisms are externally mounted, leading to issues such as lost or incorrectly secured components, which can result in unauthorized access and delayed access in emergency situations, as they do not effectively prevent unauthorized operation of the firearm.
Innovation Solution
A sliding trigger enclosure system for long guns, featuring a frame secured to the firearm receiver with factory-supplied hardware, a sliding shoulder stock, and a locking mechanism with spring-loaded pins and user authentication devices like combination locks or biometric sensors to securely transition between a SAFE and FIRE position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external locking mechanisms are mounted on the firearm, then unauthorized access can be prevented, but the components can become lost or be incorrectly secured
Solution Approach 1:
The locking mechanism is merged with the stock assembly to form an integrated unit. The stock assembly includes the locking mechanism, trigger guard, and authentication device as a single integrated structure that cannot be lost or misplaced, eliminating the reliability issue of separate external locks.
Solution Approach 2:
The stock assembly is designed as a removable module that can be detached from the firearm receiver. This segmentation allows the entire locking system to be securely attached or removed as one unit, preventing loss of components while maintaining ease of operation through simple attachment/detachment.
2Reliability
If external locking mechanisms are used, then the firearm can be secured, but access may be delayed in emergency situations
Solution Approach 1:
The authentication device is integrated directly into the stock assembly, allowing the authorized user to authenticate and release the locking mechanism quickly without needing to search for separate keys or codes. The system serves itself by having all authentication components built-in at the point of access.
3Ease of operation
If the trigger guard is open to allow quick access, then emergency access is enabled, but unauthorized access becomes possible
Solution Approach 1:
The trigger guard is designed to dynamically change its position - it can be in a closed position to prevent unauthorized access, or an open position to allow quick access. The guard is movable and can transition between these states based on authentication, providing both security and rapid access capability.
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 a secure, integrated locking solution that prevents unauthorized access and ensures immediate access in emergencies by defaulting to a locked state, enhancing firearm safety and usability.
Implementation Method 1
The locking mechanism can include a pair of spring-loaded locking pins that are engaged by an actuator.

AI summary
A sliding trigger enclosure system for a long gun includes a frame that is removably secured to the receiver of a firearm by factory-supplied hardware, and a hollow shoulder stock having a pair of side surfaces that extend outward from the front end. The shoulder stock is slidingly engaged over the frame and transitions between a FIRE position where the trigger assembly of the long gun is accessible, and a SAFE position where the pair of side surfaces are locked in a parallel orientation to the trigger assembly to prevent access to the same. A locking mechanism is disposed along the frame and secures the shoulder stock in the SAFE position. The locking mechanism including a pair of spring-loaded locking pins that are engaged by an actuator, and a user authentication device.
