Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If video-based motion capture systems are used, then motion data can be captured, but the system is not portable and requires fixed equipment setup
Solution Approach 1:
The patent replaces complex mechanical video-based motion capture systems with wearable electronic sensors that directly measure motion parameters. This substitution enables portable, real-time motion tracking without requiring fixed camera equipment or complex setup, while maintaining measurement precision through direct sensor measurement of acceleration, velocity, and position.
2Measurement precision
If wearable sensors are used, then positional data is provided, but the data requires professional interpretation and the sensors cannot be located in precisely reproducible positions
Solution Approach 1:
The system incorporates automated algorithms and processing logic that enable the sensors to self-calibrate and self-analyze their data without requiring professional interpretation. The sensors include onboard processors that automatically calculate motion parameters, correct for positioning variations, and generate actionable feedback, making the system self-sufficient and eliminating the need for expert analysts.
3Loss of information
If video or motion data is displayed in computer tables or graphs, then numerical results are shown, but a trained professional is needed to interpret the data
Solution Approach 1:
The system implements automated feedback mechanisms that process motion data through algorithms and provide immediate, actionable performance feedback to users. The feedback system automatically compares measured motion against ideal patterns, identifies deviations, and provides real-time guidance for correction, eliminating the need for professional interpretation while preserving all motion information.
4Measurement precision
If current motion capture systems are used, then motion analysis is possible, but real-time feedback during or immediately post training is not available
Solution Approach 1:
The system provides continuous real-time motion tracking and immediate feedback during and after training activities. The wearable sensors continuously monitor motion parameters and the onboard processing immediately analyzes the data, providing uninterrupted feedback loops that eliminate delays between action and feedback, enabling real-time performance optimization.
Data Source
AI summary
A highly portable system includes the necessary logic and analysis to provide immediate feedback and corrective instruction for any suitable motion. In particular, the system includes a capability for tracking individual shooter performance in a more comprehensive way, in order to provide an organized and methodical feedback to the shooter for the purpose of data-supported improvement, as well as the opportunity to improve marksmanship using dry-fire techniques, when a shooting range is unavailable and/or to reduce ammunition consumption.
