Solution Overview

Problem

Conventional guns face safety issues due to mechanical connections between the trigger and sear, leading to accidental discharges and vulnerabilities from tampering with safety mechanisms, limiting adjustability and safety features.

Innovation Solution

An electromechanical trigger system that removes the direct mechanical connection between the trigger and sear, utilizing a detent mechanism for adjustable trigger feel, a trigger sensing mechanism to identify a trigger break, and an actuator mechanism to fire projectiles only when authorized, incorporating both mechanical and electrical safeties.

Solution Approach 1:

The patent replaces the direct mechanical connection between trigger and sear with an electromechanical system. The trigger mechanism includes electrical components (solenoid, switch, battery) that mediate the firing process, eliminating the direct mechanical linkage that causes safety issues while maintaining functional reliability through electrical control

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces mechanical safety mechanisms with an electromechanical safety system. The safety function is achieved through electrical components (solenoid control, switch positions, battery presence detection) rather than mechanical blocks or levers, reducing mechanical complexity while maintaining safety functionality

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces electrical components as intermediaries between the trigger and sear. The solenoid and switch act as mediators that control the firing process, providing safety functions without requiring direct mechanical safety mechanisms that can be tampered with

Solution Approach 1:

The patent makes the trigger mechanism dynamic and adjustable through electrical control. The solenoid can be repositioned, the switch can be configured in different positions, and the battery can be removed or inserted, allowing the trigger characteristics to be changed without mechanical modifications while maintaining ease of operation

AI summary

The present disclosure provides systems and techniques for an electromechanical trigger that is implementable in a gun. The gun may include a trigger mechanism, a trigger sensing mechanism, and a fire control manager. The fire control manager may identify a trigger break based on the trigger sensing mechanism generating a voltage, and the fire control manager may transmit a signal to an actuator mechanism based on the trigger break. A detent mechanism may be dislocated in response to a force applied to a trigger mechanism, and the trigger sensing mechanism may generate the voltage based on the dislocating of the detent mechanism. Dislocating the detent mechanism may correspond to satisfying a trigger break threshold. The actuator mechanism may be displaced in response to the signal, and displacing the actuator mechanism may result in a projectile being propelled from the gun.
