Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual data entry is used for shot counting, then the system is simple to implement, but human error increases and data accuracy deteriorates
Solution Approach 1:
The patent replaces manual mechanical data entry with an automated electronic shot counting system using sensors (accelerometers, microphones) and signal processing algorithms. The sensor module detects shot events automatically, and the processing module counts and records shots without human intervention, eliminating manual errors while maintaining simplicity through integrated electronics.
2Measurement precision
If expert intervention is used for algorithm development, then shot detection accuracy is improved, but development time increases and productivity decreases
Solution Approach 1:
The patent enables the shot counting system to automatically adapt and optimize its own algorithm through machine learning. The processing module uses detected shot patterns to refine counting accuracy over time without requiring external expert intervention for each new weapon type or configuration, thus maintaining high accuracy while accelerating development and deployment.
3Adaptability or versatility
If customization for personalized projectile launchers is implemented, then adaptability improves, but development time increases and productivity decreases
Solution Approach 1:
The patent implements a dynamic, adaptable shot counting system that can be quickly configured for different projectile launcher types through software parameters rather than hardware redesign. The algorithm automatically adjusts to different weapon characteristics (fire rate, recoil patterns, sensor configurations), enabling rapid customization for personalized launchers without extending development cycles.
4Extent of automation
If automated shot counting algorithm is generated, then labor time is reduced, but computation time increases and device complexity increases
Solution Approach 1:
The patent divides the shot counting system into distinct functional modules: a sensor module for data acquisition, a processing module for signal analysis and shot detection, and a counting module for tallying events. This segmentation allows each module to be optimized independently, reducing overall system complexity while maintaining high automation. The processing module uses segmented signal processing techniques to analyze complex sensor data efficiently.

AI summary
The present invention relates to an automated system and method for a projectile launcher monitoring. The automated projectile launcher monitoring system comprises a projectile attachment and a processing module. The projectile attachment coupled with a projectile launcher includes a sensor module and a communication module. The projectile attachment acquires signals from the sensor module and converts them into a time-sampled data. The communication module sends the time-sampled data to the processing module corresponding to a shooting plan. The processing module is coupled with the projectile attachment and configured process the time-sampled data to generate a monitoring model. The processing module produces at least one-shot candidate from the time-sampled data when at least one metric is satisfied, and deploys an instance-level classifier to categorize the at least one shot candidate to generate at least one prediction. The processing module further computes an estimated proportion by aggregating the at least one prediction, compares the estimated proportion with a real proportion to determine a loss function, and generates the monitoring model through an iterative process until a predetermined minimal loss is achieved.
