ECMO Firearm Safety Mechanism with Biometric Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm safety mechanisms, such as grip safeties and external mechanical safety switches, are ineffective in preventing unauthorized use by adults and can be cumbersome, especially in emergency situations, as they rely solely on mechanical components and do not provide robust authentication processes.
Innovation Solution
The implementation of an electronically controlled, mechanically operated (ECMO) firearm safety system that includes a processor, sensors, and a safety mechanism with a first position blocking trigger actuation and a second position allowing actuation, which is authenticated through input codes, biometric data, or mobile device communication, ensuring only authorized users can unlock the firearm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mechanical safety mechanisms (grip safeties, external safety switches) are used, then the firearm can be operated with simple mechanical components, but these mechanisms cannot prevent unauthorized use by adults and are cumbersome in emergency situations
Solution Approach 1:
The patent replaces conventional purely mechanical safety mechanisms with an electronically controlled system that uses sensors, processors, and electronic circuits to authenticate users. The electronic system evaluates multiple factors (grip pressure, trigger pressure, biometric data) to determine authorization, providing more reliable security against unauthorized use while maintaining mechanical components for actual firing control.
Solution Approach 2:
The patent introduces electronic control systems as intermediaries between the user and the firing mechanism. The electronic safety mechanism acts as a mediator that processes authentication data from various sensors and controls the mechanical trigger assembly accordingly, enabling sophisticated authentication without requiring complex direct mechanical safety devices.
2Reliability
If electronically controlled safety mechanisms with multiple authentication factors are implemented, then unauthorized use is prevented more effectively, but the device complexity and number of components increase
Solution Approach 1:
The patent combines multiple authentication functions (grip detection, trigger pressure sensing, biometric scanning) into a single integrated electronic safety mechanism. The processor consolidates data from various sensors and controls multiple authentication factors through one unified electronic system, reducing the need for separate complex subsystems while maintaining high security standards.
Solution Approach 2:
The electronic safety mechanism is designed to perform multiple functions: detecting grip presence, measuring trigger pressure, scanning biometric data, evaluating authentication criteria, and controlling the mechanical trigger assembly. This multi-functional approach allows the system to provide comprehensive security without requiring separate dedicated components for each function.
3Object-affected harmful factors
If mechanical safeties require specific hand size and strength (grip safeties), then children are prevented from firing, but authorized adult users may have difficulty in emergency situations
Solution Approach 1:
The patent employs feedback mechanisms where sensors continuously monitor grip pressure, trigger pressure, and biometric data. The processor evaluates this real-time feedback against stored authentication criteria, allowing the system to quickly verify authorized users in emergency situations without relying on physical characteristics like hand size that may slow down the authentication process.
Solution Approach 2:
The system performs preliminary authentication by detecting grip presence and evaluating initial biometric data before the user even attempts to pull the trigger. This preliminary action prepares the electronic safety mechanism in advance, so that when an emergency firing situation occurs, the authentication process is already partially complete or can be rapidly finalized, improving response time.

AI summary
The techniques described herein relate to methods and apparatus for firearm safety mechanisms, visual safety indicators, and related techniques. A firearm includes a handle comprising one or more buttons disposed at least partially within a surface of the handle, such that the one or more buttons can be in contact with an operator's hand when the operator grasps the handle; a safety mechanism in mechanical communication with the trigger. The safety mechanism comprises: a first position that blocks actuation of the trigger; and a second position that does not block actuation of the trigger; and at least one processor configured to: upon determining an input code matches a stored code, transmits a signal to the safety mechanism to change the safety mechanism from the first position to the second position so that the firearm can be fired by the operator.
