Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If coaching is used to improve pitching performance, then subjective guidance is provided, but measurement accuracy and objectivity deteriorate
Solution Approach 1:
The patent replaces subjective human coaching with an automated system using inertial sensors, computer algorithms, and machine learning to objectively measure and analyze pitching mechanics. This substitution eliminates human subjectivity while providing precise, data-driven feedback on throwing motion parameters.
Solution Approach 2:
The system enables pitchers to self-analyze their mechanics through automated feedback without requiring expert coaches. The computer algorithm independently processes sensor data, identifies mechanical issues, and generates corrective recommendations, making the coaching function self-serviceable.
2Loss of information
If high-speed video capture is used to monitor throwing motion, then visual recording is achieved, but measurement capability for torque and rotation deteriorates
Solution Approach 1:
The patent replaces visual video capture with inertial sensors that directly measure physical quantities such as acceleration, rotation, and torque. This substitution transforms qualitative visual information into quantitative mechanical data, enabling precise measurement of parameters that video cannot capture.
Solution Approach 2:
The patent introduces inertial sensors as intermediaries between the throwing motion and the analysis system. These sensors directly attach to the athlete's body segments to capture mechanical data, serving as a mediator that bridges the gap between complex human motion and computable metrics.
3Loss of information
If traditional video analysis is used to assess player mechanics, then visual documentation is provided, but objective measurement capability deteriorates
Solution Approach 1:
The patent replaces traditional video analysis methodology with inertial sensor-based measurement. This substitution fundamentally changes the approach from visual observation to direct physical measurement, eliminating the inherent limitations of video while providing objective, quantifiable data.
