Universal Fixed Pin Trigger Block for Firearm Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trigger locks for firearms are not designed to be universal for a family of guns from a particular manufacturer, leading to logistical challenges and inefficiencies in inventory management, as they typically require individualized locks for each firearm model, which can result in costly waste and inconvenience.
Innovation Solution
A universal trigger lock with multiple stationary pins and hardened steel plates that fit all rifles, shotguns, or handguns from a single manufacturer, preventing firing and saw insertion, while meeting safety standards, by using pin layouts determined through profiling of firearm models to accommodate various firearm profiles and prevent movement attempts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individualized trigger locks are designed for each firearm model, then the lock fits the specific firearm profile perfectly, but inventory management becomes complex and costly
Solution Approach 1:
The trigger lock is designed with a universal plate configuration and pin layout that can accommodate multiple firearm models from the same manufacturer. The plate includes multiple pin insertion holes arranged to work with different trigger guard shapes and sizes, allowing a single lock design to serve multiple firearm types while maintaining secure fitting.
2Adaptability or versatility
If retractable spring biased pins are used, then the lock can fit many different firearms, but some pins may be blocked by firearm features
Solution Approach 1:
Different regions of the plate are designed with specific pin hole configurations optimized for different firearm types. The plate includes strategically positioned pin holes that accommodate various trigger guard profiles, with some holes positioned to avoid blocking by firearm features while ensuring secure engagement.
3Strength
If stationary pins are positioned to abut trigger guard parts, then the plates are held securely in position, but the design must be customized for each firearm
Solution Approach 1:
The pin arrangement is segmented into multiple functional groups: some pins are positioned to abut trigger guard parts for secure positioning, while other pins extend to engage with corresponding features on the opposite plate. This segmented approach allows the same plate design to achieve secure positioning across multiple firearm models.

AI summary
A firearm trigger locking device with two sides and fixed hardened steel pins. The device is designed to be universal for a particular family of guns—e.g., all rifles, all shotguns, or all handguns (or all revolvers or automatic pistols)—of a given firearm manufacturer. The device further features a pin behind the trigger to prevent firing, hardened steel plates in each side sufficient in size to cover the trigger guard and prevent transverse application of a saw to the trigger guard, and a ring of hardened steel pins around the periphery of the trigger guard to prevent application of a saw between the plates. The method for producing this trigger locking device uses lateral and axial profiles of the family of firearms to develop features and feature locations that will allow it to be used with any member of the family of firearms.
