Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearm locks do not have the capability to engage and lock a firearm when screams occur nearby, which is a critical need in preventing unauthorized discharge during events like mass shootings.
Innovation Solution
An audio-controlled firearm locking system comprising a locking module and an electronics module with a microphone and microprocessor that detects screams and actuates the locking mechanism to prevent discharge, using criteria such as frequency and duration of audio signals to differentiate screams from other loud vocalizations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an audio-controlled locking system is added to detect screams and lock the firearm, then the safety response capability to screaming events is improved, but the device complexity increases
Solution Approach 1:
The patent combines the locking mechanism and audio detection electronics into an integrated firearm safety system. The locking module, electronics module with microphone and microprocessor, and power supply are merged into a unified system that automatically detects screaming events and engages the locking mechanism, eliminating the need for separate manual safety devices.
Solution Approach 2:
The patent replaces manual mechanical safety operations with an automated acoustic detection and response system. Instead of requiring users to manually engage safety mechanisms, the system uses a microphone to detect screaming events, processes the audio signals through a microprocessor, and automatically actuates the locking module through electrical actuation.
2Reliability
If the locking mechanism engages on any loud vocalization, then the safety response is more sensitive, but the false activation rate increases
Solution Approach 1:
The patent uses specific acoustic parameters to distinguish screaming events from other vocalizations. The microprocessor analyzes audio signals for characteristic features of screams such as frequency range, duration, intensity patterns, and spectral characteristics, enabling selective activation only for genuine screaming events while ignoring normal conversation, shouting, or other non-scream vocalizations.
Solution Approach 2:
The system incorporates audio signal analysis feedback to determine whether to activate the locking mechanism. The microprocessor continuously monitors the audio input from the microphone, analyzes the characteristics of detected sounds, and uses this feedback to make intelligent decisions about activation, thereby reducing false positives while maintaining sensitivity to actual screaming events.
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
Effectively prevents the discharge of a firearm when screams are detected, ensuring safety by selectively locking the firearm based on specific audio criteria, while allowing for self-defense scenarios by ignoring the user's or specific individuals' screams.
Implementation Method 1
The microphone detects audio signals proximate to the firearm and relays the audio signals to the microprocessor

AI summary
An audio controlled firearm locking system for locking a firearm while screaming is occurring proximate to the firearm includes a locking module and an electronics module, which are mountable to the firearm. The locking module is selectively engageable to at least one movable element of the firearm, movement of which is required to discharge the firearm, thereby allowing the locking module to selectively lock the firearm. The electronics module comprises a battery, a microprocessor, and a microphone. The microprocessor is operationally engaged to the locking module, the battery, and the microphone, which detects audio signals proximate to the firearm and relay the audio signals to the microprocessor. The microprocessor is programmed to analyze the audio signals for an indication of a screaming event. When a screaming event is indicated, the microprocessor actuates the locking module to prevent discharge of the firearm.
