Smartphone Gun Lock with Biometric and GPS Override
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gun locks are vulnerable to unauthorized use, as they can be compromised with master keys or lock picks, and do not prevent use by authorized individuals in inappropriate or dangerous situations, such as when the user is intoxicated or acting irrationally.
Innovation Solution
A smartphone-operated gun lock system that uses biometric data and GPS location to control the gun's firing state, allowing only authorized individuals to unlock the gun, and includes features like a breathalyzer and timer to ensure responsible use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mechanical key-based gun lock is used, then the gun can be locked and unlocked, but the lock can be easily compromised by master keys or lock picks and keys can be easily duplicated
Solution Approach 1:
The patent replaces the mechanical key-based locking system with an electronic control system that uses a smartphone application to send wireless signals (Bluetooth or other radio frequency) to actuate the lock mechanism. This substitution eliminates physical keys that can be duplicated or picked, while using well-established wireless communication and authentication technologies to achieve secure access control.
2Ease of operation
If an authorized person can unlock the gun at any time, then the gun is accessible when needed, but the gun can be fired in inappropriate or dangerous situations such as when the user is intoxicated or acting irrationally
Solution Approach 1:
The patent incorporates a feedback mechanism where the smartphone application monitors the user's physiological state through sensors (such as breathalyzer integration, heart rate monitoring, or other biometric sensors) before allowing the gun to be unlocked. The system continuously or periodically checks user status and only permits access when the user is determined to be sober and mentally capable, thereby preventing inappropriate use while maintaining accessibility when conditions are appropriate.
3Reliability
If a smartphone-based authentication system is implemented, then only authorized individuals can use the gun, but the system requires multiple components including smartphone, app, and communication protocols
Solution Approach 1:
The patent leverages the smartphone as a multi-functional device that already possesses authentication capabilities (biometric sensors, communication interfaces, processing power) and uses an application layer to provide gun-specific control functions. By utilizing the smartphone's existing universal capabilities rather than requiring a dedicated specialized device, the system achieves strong authorization control while minimizing additional hardware complexity.
4Reliability
If the gun lock system includes monitoring features like breathalyzer and GPS locator, then inappropriate use can be prevented, but the device complexity and cost increase
Solution Approach 1:
The patent uses the smartphone application as an intermediary layer that interfaces with external monitoring devices (breathalyzer, GPS locator, other sensors) rather than requiring these components to be integrated directly into the gun lock mechanism. The smartphone's existing sensors and communication capabilities serve as intermediaries to gather monitoring data and process authentication, enabling comprehensive safety monitoring while keeping the core gun lock system relatively simple.
Data Source
AI summary
A gun locking and unlocking device, which may be configured to be disposed adjacent the trigger of a gun to alternatively prevent or enable firing, includes a data receiver, a data memory and a logic device for determining whether data received by the receiver is the same, or substantially the same, as data stored in the data memory. One or more separate electronic gun keys are provided to transmit gun lock/unlock data to the data receiver of the gun lock device. The logic device responds to a gun control signal transmitted by one of the gun key devices with priority over a gun control signal transmitted by another gun key device. The logic device automatically locks the gun when it is located in a prohibited area, such as a school. The logic device also locks the gun when the gun user is intoxicated or acting in an irrational manner. Once locked, the user must set a timer which allows the gun to be unlocked only after a specified “wait” time.
