Solution Overview

Problem

Firearms lack effective, quick-release safety mechanisms to prevent accidental discharges, particularly in designs like revolvers and small conceal-and-carry semiautomatics, where internal or external safeties are either absent or only suitable for long-term storage, and conventional trigger locks are cumbersome for rapid use.

Innovation Solution

A flexible, adjustable trigger plug made of rubberized material that fits behind the firearm trigger, acting as a physical obstruction to prevent accidental discharge and can be easily installed and removed, accommodating various firearm designs and sizes through adjustable features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

AI summary

A flexible adjustable trigger plug is a device that is utilized to prevent the accidental pressing and subsequent discharge of a firearm trigger. The device features a plug that may be fitted behind the trigger as well as a first lip and a second lip that are able to hold the plug in place behind the trigger. A first concave cavity and a second concave cavity are present as well in order to facilitate insertion and removal of the device by pressing. The device serves as a physical obstruction that prevents the trigger from being accidentally pressed. The device is flexible and may be adjusted by turning the device when in place behind the firearm trigger, allowing the device to be utilized with a wide variety of firearms. The device may feature a lanyard arch and opening that allow a lanyard clasp or clip to be secured to the device.
