Firearm Wear Monitoring via RuBee Radio Tag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms experience wear and tear that is difficult to accurately monitor, leading to inaccurate maintenance scheduling, especially in high-fire-rate situations, where the rate of fire significantly affects the weapon's lifespan, accuracy, and safety.
Innovation Solution
A RuBee® radio tag system is attached to the firearm, which tracks the number of shots fired and the intervals between shots, calculating a weighted Mean Kinetic Shot Count (MKSC) to provide a comprehensive measure of wear and tear, incorporating sensors and a programmable transceiver for real-time data transmission and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual tracking of shot count and firing cadence is used, then the system complexity is low, but the measurement precision of firearm wear monitoring deteriorates
Solution Approach 1:
The patent replaces manual mechanical tracking methods with an automated electronic monitoring system that uses sensors to detect shots fired and microprocessors to calculate firing cadence and cumulative wear metrics, thereby improving measurement precision while accepting increased system complexity
Solution Approach 2:
The monitoring system is self-activating and automatically tracks shot count and firing cadence without requiring human intervention, with the microprocessor continuously calculating wear metrics based on sensor inputs, eliminating the need for manual recording while maintaining precise measurement
2Measurement precision
If automated shot tracking system is implemented, then the measurement precision of firearm wear monitoring is improved, but the device complexity increases
Solution Approach 1:
The monitoring system is designed to serve multiple functions: detecting shots fired, counting shots, calculating firing cadence, computing cumulative wear metrics, and providing maintenance alerts, thereby justifying the increased device complexity through enhanced measurement precision and comprehensive wear monitoring capabilities
Solution Approach 2:
The system continuously monitors firing parameters and provides real-time feedback on cumulative wear metrics and maintenance status, enabling precise tracking of firearm degradation while using the collected data to optimize maintenance scheduling and extend weapon service life
3Ease of operation
If maintenance scheduling is based on shooter memory, then the ease of operation is high, but the reliability of maintenance timing deteriorates
Solution Approach 1:
The patent replaces human memory-based maintenance scheduling with an automated electronic system that continuously tracks shot count and firing cadence, calculating cumulative wear metrics to determine precise maintenance timing, thereby improving reliability while reducing ease of operation through increased system complexity
4Productivity
If high rate of fire is sustained, then the productivity of the firearm is improved, but the duration of action of firearm components deteriorates
Solution Approach 1:
The monitoring system provides continuous feedback on cumulative wear metrics calculated from firing cadence and shot count data, enabling operators to adjust firing rates to optimize the balance between productivity and component lifespan, preventing excessive wear during sustained high-rate fire while maximizing operational effectiveness
Solution Approach 2:
The system calculates and tracks cumulative wear metrics in advance, providing early warning indicators that allow maintenance to be scheduled before critical wear thresholds are reached, thereby extending the duration of action of firearm components through proactive maintenance based on actual usage patterns
Data Source
AI summary
A method for identifying, tracking, and monitoring a firearm includes steps of: attaching a low frequency radio tag to the firearm; storing, in the data storage device of the radio tag, identification data relating to the firearm; and reading the identification data from the transceiver by interrogating the radio tag. The radio tag includes a shot sensor, a shot count register for tracking the number of shots fired and cadence registers for tracking the intervals between shots.
