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 using input codes, biometric data, or mobile device communication to ensure authorized use.
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 they 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 (pressure sensors, biometric sensors), processors, and electronic authentication methods. The grip safety includes pressure sensors that detect hand pressure, and the system can incorporate fingerprint scanners or other biometric authentication, substituting mechanical operation with electronic control while maintaining mechanical backup components
Solution Approach 2:
The patent introduces an intermediary electronic control system between the user and the firing mechanism. The processor acts as an intermediary that receives input from various sensors (pressure sensors in the grip, biometric sensors), processes authentication data, and then controls the safety mechanism state accordingly, adding a layer of intelligent mediation
2Object-affected harmful factors
If grip safeties requiring certain hand size and strength are used, then children are limited from firing the weapon, but they also limit the ability of most children to fire the weapon and cannot prevent unauthorized adult use
Solution Approach 1:
The patent changes the authentication parameters from purely mechanical (hand size, grip strength) to electronic and biometric parameters. Pressure sensors detect specific pressure thresholds, biometric sensors verify unique physiological characteristics, and the system can accommodate different hand sizes by adjusting electronic thresholds rather than relying on fixed mechanical dimensions
Solution Approach 2:
The patent implements preliminary authentication actions before allowing firearm operation. The system requires users to authenticate through pressure sensor patterns, biometric verification, or code entry before the safety mechanism transitions to a firing-permissive state, ensuring authorized use before operation is enabled
3Ease of operation
If external mechanical safety switches with multiple positions are used, then the safety can be operated by both children and adults, but they are cumbersome to use and can fail to provide quick and safe firearm use in emergency situations
Solution Approach 1:
The patent replaces manual manipulation of mechanical safety switches with electronic control systems that can detect emergency conditions automatically. Pressure sensors, accelerometers, and other sensors can detect distress situations and automatically adjust safety settings, eliminating the need for manual switch operation during emergencies
Solution Approach 2:
The patent enables the safety system to serve itself by automatically monitoring various parameters (pressure, motion, biometric data) and adjusting its own state based on detected conditions. The processor continuously evaluates sensor input and autonomously controls the safety mechanism without requiring manual intervention, allowing the system to respond instantly to emergency situations

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.
