Solution Overview

Problem

Conventional firearm safety mechanisms, such as grip safeties and external mechanical safety switches, are inadequate in preventing unauthorized use, particularly by adults, and can be cumbersome 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 locked and unlocked position, which requires user authentication through input codes, biometric data, or mobile device communication to change states, ensuring secure and controlled firearm operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional mechanical safety mechanisms are used, then the firearm can be operated with simple mechanical components, but the safety mechanism cannot prevent unauthorized use by adults and is cumbersome in emergency situations

Engineering Contradiction:
Improvesafety mechanism effectivenessVSAvoidoperation speed
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces purely mechanical safety mechanisms with an electronically controlled system that uses sensors, processors, and electronic circuits to detect user characteristics (such as hand size, grip pressure, and biometric data) and control the trigger mechanism accordingly. This substitution enables more sophisticated authentication while maintaining mechanical reliability for critical functions.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The safety mechanism automatically detects and authenticates the user through sensors that measure physical characteristics such as hand size, grip pressure, and biometric data without requiring manual intervention. The system self-determines whether to enable or disable the trigger based on these detected characteristics, eliminating the need for manual safety switch operation.

Inventive Principle:
Principle #25Self-service

2Object-affected harmful factors

If grip safeties requiring certain hand size and strength are used, then children are limited from firing the weapon, but the safety cannot prevent unauthorized adult use

Engineering Contradiction:
Improvechild access preventionVSAvoiduser authentication capability
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The safety mechanism incorporates multiple authentication methods including hand size detection, grip pressure sensing, biometric data collection (fingerprints, facial recognition), and electronic code verification. This multi-functional approach allows the single safety system to prevent child access through physical characteristics while simultaneously enabling authorized adult access through various authentication modes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system monitors and responds to changes in multiple parameters simultaneously: hand size dimensions, grip pressure force, biometric template matches, and electronic code inputs. By evaluating combinations of these parameters rather than relying on a single threshold, the system accurately distinguishes between unauthorized children and authorized adults with varying hand sizes and strengths.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If external mechanical safety switches with multiple positions are used, then both children and adults can operate the safety, but the safety is cumbersome to use and can fail to provide quick and safe firearm use in emergency situations

Engineering Contradiction:
Improvesafety mode optionsVSAvoidsafety operation steps
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical safety switches with an electronically controlled system that automatically transitions between safety states based on sensor inputs and processor decisions. The electronic system eliminates the need for users to manually move mechanical switches between multiple positions, reducing operational steps while maintaining multiple safety modes through software control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The safety mechanism automatically detects the desired safety state through sensor inputs (such as detection of a target, user authentication status, or emergency conditions) and self-adjusts the trigger blocking mechanism accordingly. This eliminates the need for manual safety switch operation by having the system service itself through automated state transitions based on environmental and user context.

Inventive Principle:
Principle #25Self-service

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.
