Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional observation and self-perception methods are used for measurement, then the measurement process is simple, but the measurement precision and objectivity deteriorate
Solution Approach 1:
The patent replaces subjective mechanical observation methods with electronic sensing systems. Strain sensors mounted on paddles convert mechanical stroke forces into electrical signals, which are then processed and transmitted wirelessly to provide objective, quantifiable data about stroke characteristics, thereby improving measurement precision while maintaining practical system complexity
Solution Approach 2:
The patent introduces intermediate devices including strain sensors, signal processing units, and wireless communication modules that mediate between the physical stroke action and the final measurement data. These intermediaries transform raw mechanical forces into processed, actionable information that can be analyzed in real-time
2Loss of information
If video analysis systems are used to record and analyze stroke movements, then objective data can be obtained, but post-processing work increases significantly and real-time feedback is not provided
Solution Approach 1:
The patent implements real-time feedback by continuously monitoring stroke parameters through strain sensors and immediately transmitting processed data via wireless communication to coaching stations. This allows coaches and athletes to receive instant information about stroke force, rate, and symmetry, enabling timely adjustments during training sessions without requiring post-session video analysis
Solution Approach 2:
The patent replaces time-consuming video recording and manual analysis systems with electronic sensing and automated data processing. Strain sensors continuously capture stroke dynamics, microcontrollers process the signals in real-time, and wireless transmission delivers results instantly, eliminating the delayed feedback inherent in video analysis workflows
3Loss of information
If wearable devices are used to record physiological data, then physiological information can be collected, but the data does not directly reflect stroke movement quality and efficiency
Solution Approach 1:
The patent applies local quality by placing strain sensors directly on the paddles at specific locations where stroke forces are generated. This localized measurement approach captures the actual mechanical characteristics of each stroke action, providing direct information about stroke quality and efficiency rather than indirect physiological proxies
