Solution Overview

Problem

Firearms are often stored in insecure locations, making them accessible to unauthorized users, such as children or burglars, posing a risk to personal safety and security.

Innovation Solution

A firearm tracker system comprising a device attached to the firearm's picatinny rail, equipped with motion sensors, wireless transmitters, and an audible alarm, which alerts an authorized user via a personal electronic device when an unauthorized user attempts to handle the firearm, triggering visual and audible alerts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If firearms are stored in secure locations under lock and key, then security against unauthorized access is improved, but accessibility for authorized users may be reduced

Engineering Contradiction:

Improvefirearm securityVSAvoidfirearm accessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The tracker system automatically monitors and detects unauthorized access attempts without requiring continuous human supervision. The motion sensors and wireless transmitters enable the firearm storage system to self-report security events to the authorized user's mobile device, eliminating the need for constant manual checking while maintaining security.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system provides real-time feedback to the authorized user through wireless communication when motion is detected near the firearm. This feedback loop allows the user to be immediately notified of potential security breaches while the firearm remains stored in its secure location, resolving the contradiction between security and accessibility.

Inventive Principle:

Principle #23Feedback

2Reliability

If motion sensors and alert systems are installed on the firearm, then detection of unauthorized handling is improved, but device complexity increases

Engineering Contradiction:

Improveunauthorized access detectionVSAvoidtracker system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The tracker device performs multiple functions within a single integrated unit: motion sensing, wireless transmission, audio alert generation, and visual indication. By combining these functions into one compact device that attaches to the firearm, the system achieves reliable unauthorized access detection without proportionally increasing overall complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The wireless transmitter acts as an intermediary between the motion sensor and the authorized user's mobile device. This intermediary component enables communication without requiring direct physical connection or complex wiring, simplifying the overall system architecture while maintaining reliable detection and notification capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If audible alarms and visual indicators are activated, then deterrent effect against unauthorized users is improved, but energy consumption increases

Engineering Contradiction:

Improveunauthorized user deterrentVSAvoidbattery power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The audible alarm and visual indicator are activated periodically only when motion is detected, rather than operating continuously. This periodic activation triggered by motion sensors significantly reduces energy consumption while maintaining an effective deterrent effect, as the alerts occur only when potentially unauthorized access is attempted.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system activates alerts as a preliminary response to detected motion, creating a deterrent effect before actual unauthorized access can occur. This preliminary anti-action prevents harmful outcomes by discouraging potential intruders through immediate audio and visual warnings, thereby protecting the firearm without requiring continuous energy-intensive operation.

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

A tracker for a firearm comprises a device capable of being secured to a Picatinny® rail of a firearm. The device is in wireless communication with a smart electronic device thereby alerting a user of when the firearm has been moved. The device also comes with an audio alert which issues forth a high decibel and painful sound to dissuade unauthorized use.
