Weapon Shot Counting Device Using Periodic Magnetic Field Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shot counting devices for weapons only track the number of undetonated cartridges and do not accurately determine if a shot has been fired, failing to account for cartridge loss during mounting or defective discharges, and lack comprehensive information on firing frequency and weapon maintenance.
Innovation Solution
A counting device integrating an activator sensor and a processor with a counting sensor that measures magnetic or electromagnetic fields before and after a potential shot, using a time interval to differentiate between cartridge changes due to firing and other events, providing accurate counts of shots fired and cartridges stored, while minimizing power consumption and avoiding false counts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the counting sensor continuously measures to track cartridge changes, then the accuracy of shot counting is improved, but the energy consumption increases
Solution Approach 1:
The counting sensor operates periodically rather than continuously, being activated only during predetermined time intervals when cartridge changes are expected to occur. This periodic measurement approach maintains shot counting accuracy while significantly reducing energy consumption compared to continuous monitoring.
Solution Approach 2:
The system performs preliminary actions by predicting when cartridge changes will occur based on weapon firing cycles, and activates the counting sensor in advance during these predetermined time intervals. This allows accurate tracking of cartridge depletion without requiring continuous sensor operation.
2Device complexity
If the counting device tracks only undetonated cartridges, then the device complexity is reduced, but the reliability of shot counting information deteriorates
Solution Approach 1:
The system uses feedback from the activator sensor that detects weapon discharge events to trigger the counting sensor. This feedback mechanism allows the device to reliably determine whether a shot was actually fired by correlating cartridge depletion with detected discharge events, improving shot counting reliability without significantly increasing device complexity.
Solution Approach 2:
The invention merges the functions of detecting undetonated cartridges with detecting actual shot events into a single integrated counting device. By combining the counting sensor that tracks cartridge numbers with the activator sensor that detects discharges, the system provides reliable shot counting information while maintaining relatively simple device architecture.
3Speed
If the counting sensor operates continuously to detect cartridge changes, then the response time is improved, but the loss of energy increases
Solution Approach 1:
The counting sensor performs measurements periodically during predetermined time intervals when cartridge changes are expected, rather than operating continuously. This approach maintains adequate response time to detect shot events while minimizing energy loss by keeping the sensor inactive during intervals when no changes are expected.
