Modular Trigger Lock with Universal Mounting Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trigger locks for firearms are often custom-made and not easily compatible with commonly available locks, making them inconvenient for use with multiple lock types and prone to unauthorized access or transport.
Innovation Solution
A modular trigger lock design featuring a U-shaped channel with adjustable flanges and a plug system that accommodates various locking mechanisms, including padlocks, shackle locks, and lanyards, ensuring secure access only to authorized users while allowing easy installation and compatibility with different firearm models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If custom locking devices are used to fill the trigger guard opening, then trigger access is prevented, but the locks are not readily available or easily replaced
Solution Approach 1:
The trigger lock device incorporates a standardized mounting structure with a through-hole and external threading that accepts multiple types of common locks (padlocks, shackle locks, combination locks). This universal interface allows the same trigger lock body to work with various lock types, eliminating the need for custom-made locks for each application while maintaining secure trigger guard coverage.
2Reliability
If trigger locks are designed to securely prevent trigger access, then unauthorized access is blocked, but installation complexity increases
Solution Approach 1:
The trigger lock is divided into separate modular components: a trigger lock body, a detachable mounting bracket with through-hole, and a separate locking mechanism. This segmentation allows the components to be manufactured independently and assembled easily on different firearm models without requiring complex custom fabrication or specialized tools for installation.
3Manufacturing precision
If the trigger lock uses a fixed custom design, then it fits specific firearms well, but it cannot be easily adapted to different firearm models
Solution Approach 1:
The trigger lock incorporates adjustable mounting brackets with through-holes that can be positioned at different locations on the trigger guard. The external threading allows the bracket to be adjusted to accommodate various trigger guard thicknesses and configurations. This dynamic adjustability enables the same trigger lock body to be precisely fitted to different firearm models while maintaining manufacturing simplicity.

AI summary
A trigger lock is provided with a shield member having a U-shaped channel forming a first plate and a second plate spaced apart from the first flange, with a web connecting the first and second plates. The shield member has a peripheral contour that is complementarily shaped to closely match the transition contour of a firearm, in the region of the firearm frame transitioning between the thick frame and the thin trigger guard. The shield member is fitted over the trigger guard, with the trigger guard situated within the U-shaped channel. A plug is inserted through an aperture in the first plate, through the trigger guard, and through a second aperture in the second plate. The plug is secured within the shield member by a lock attached to the end of the plug protruding from the second aperture, thus preventing access to the trigger and preventing removal or substantial movement.
