Adjustable Trigger Safety With Sequential Lever Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearm safety systems fail to prevent unintended discharges due to improper handling, lack adaptability, and do not indicate when the weapon is loaded and ready to fire, often requiring internal modifications and failing to promote proper hand grip.
Innovation Solution
An adjustable trigger safety system with a frame, safety lever, activation lever, and main safety that requires the safety lever to be depressed before the activation lever, featuring a safety cable to transfer force to the main safety, an accessory connector for external devices, and a trigger safety indicator that can rotate independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current safety systems are used, then the trigger cannot move to prevent discharge, but the user cannot know when the gun is loaded and ready to fire
Solution Approach 1:
The patent employs a colored indicator (typically a flag or marker) that changes color or position to visually indicate the safety mechanism's state. When the safety is engaged, the indicator shows one state (e.g., green or positioned), and when disengaged, it shows another state (e.g., red or positioned), allowing users to immediately know whether the firearm is loaded and ready to fire without having to physically inspect the trigger or internal mechanisms.
2Reliability
If safety systems require internal modifications to the firearm, then protection against unintended discharges is improved, but the device complexity and adaptability are reduced
Solution Approach 1:
The safety mechanism is divided into separate functional modules: a safety switch or button, a lever or actuator, and an indicator system. These segmented components can be independently manufactured, tested, and installed on various firearm platforms without requiring complex internal modifications to the firearm's core structure. The segmentation allows for standardized interfaces that can be adapted to different gun types while maintaining consistent safety functionality.
3Reliability
If safety systems are designed for specific firearm types, then protection is optimized, but the adaptability to a wide variety of firearms is reduced
Solution Approach 1:
The safety mechanism is designed with universal mounting features and standardized interfaces that allow it to be installed on multiple types of firearms including pistols, rifles, and shotguns. The system incorporates adjustable components and configurable safety switches that can be positioned to work with different trigger configurations and grip styles, enabling a single safety system design to provide protection across a wide variety of firearm platforms without requiring custom designs for each type.
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
Prevents accidental discharges by ensuring the main safety remains in the 'Safe' position until the safety lever is properly engaged, promoting proper hand grip and allowing customization to various firearms, while providing an electrical interface for external devices and indicating the system's status.
Implementation Method 1
one end of a safety cable is anchored inside the frame, and the other end of the safety cable is attached to the main safety. when depressed, the activation lever comes into contact with and applies a force to the safety cable. the safety cable will transfer the force to the main safety causing it to move from the first position to the second position

AI summary
An adjustable trigger safety system that replaces a handle or grip of a firearm is disclosed. The adjustable trigger safety system can have a frame that mounts to a portion of a firearm. A finger actuator is used to reposition an indicator that allows the main safety to rotate from a “safe” position to a “fire” position. The lower grip can have an accessory connector to connect external devices. The frame can house and provide pivot points for components located internally or partially internally to the frame, including a safety lever, an activation lever, and a safety cable. Rotation of the activation lever causes the main safety to rotate. The amount of pressure needed to move the safety and activation levers and deactivate the system is adjustable. The safety lever must be depressed before the activation lever, or the activation lever cannot be depressed. The finger actuator is ambidextrous.
