Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearm safety technologies face challenges in ensuring that only authorized individuals can use a firearm, particularly in emergency situations where biometric authentication may fail due to false positives or negatives, and existing solutions may not provide immediate access.
Innovation Solution
The implementation of RFID technology, either implanted or wearable, paired with a smart gun system that uses a spring-type hammerless firing pin and logic circuit to authenticate users, ensuring that only authorized individuals can discharge the firearm, with optional integration into bullets or magazines for power and additional safety features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If biometric authentication (fingerprint, voice recognition, DNA) is used to identify authorized users, then user identification accuracy is improved, but false positive and false negative rates increase due to hardware and software limitations
Solution Approach 1:
The patent segments the authentication process into multiple independent verification stages: initial biometric screening followed by secondary verification methods. This segmentation allows the system to catch false positives/negatives at different stages, reducing overall error rates while maintaining identification accuracy.
Solution Approach 2:
The patent introduces an intermediary verification layer between the biometric sensor and the firearm release mechanism. This intermediary includes logic circuits that cross-check biometric data against multiple criteria and can invoke alternative authentication methods, acting as a mediator that filters out false readings before they compromise safety.
2Reliability
If mechanical locks and safes are used to prevent unauthorized access, then firearm safety is improved, but access time increases due to the need to locate and operate the lock mechanism
Solution Approach 1:
The patent replaces traditional mechanical lock and safe systems with an automated electronic authentication system. The logic circuits and biometric sensors eliminate the need for manual lock manipulation, reducing access time from seconds to milliseconds while maintaining or improving safety through more reliable electronic verification.
Solution Approach 2:
The system performs preliminary authentication actions automatically before the user needs to access the firearm. The biometric sensors continuously monitor for authorized users, and the logic circuits pre-verify credentials, so that when access is needed, the system is already prepared to release the firearm immediately without requiring manual intervention.
3Ease of operation
If electronic locks (pin code, motion detection) are used to eliminate mechanical keys, then ease of operation is improved, but reliability decreases in emergency situations due to power requirements and complexity
Solution Approach 1:
The patent changes the operational parameters of the electronic lock system by implementing multiple power sources and power management modes. The system can switch between powered operation for normal use and passive mechanical operation for emergencies, changing its state based on situational parameters to maintain both convenience and reliability.
Solution Approach 2:
The patent incorporates beforehand cushioning by including backup power sources and mechanical fallback mechanisms that are prepared in advance. If the primary electronic system fails during an emergency, these pre-positioned backups immediately take over, cushioning against the reliability failure without requiring user intervention or system reconfiguration.
4Measurement precision
If RFID or wearable transponders are used for authentication, then false positive rates are reduced compared to biometric systems, but reliability decreases if the user is not wearing the device when needed
Solution Approach 1:
The patent implements universality by supporting multiple authentication modalities: RFID transponders, biometric sensors, and mechanical key backups. The system can recognize and verify different types of credentials, making it universally accessible regardless of which authentication method the user has available, thereby improving availability reliability while maintaining authentication accuracy.
Solution Approach 2:
The patent applies dynamics by making the authentication system adaptive and flexible. The logic circuits can dynamically switch between different authentication methods based on what is detected or required. If an RFID tag is detected, that method is used; if not, the system can prompt for alternative credentials or activate backup mechanisms, dynamically adjusting to ensure reliability.

AI summary
The present invention relates to smart gun technology, i.e., devices, systems, and methods, designed to ensure that the individual who is attempting to fire a weapon has been authorized to use the in-use weapon. In some embodiments, we disclose a firearm safety device having a spring-type, hammerless firing pin coupled to a logic circuit configured to uniquely identify an individual. Some embodiments employ RFID technology, which is much more reliable than most consumer-grade biometric identification mechanisms.
