Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual synchronization of swing videos is performed, then video comparison is possible, but time consumption and operational complexity increase
Solution Approach 1:
The patent replaces manual mechanical video alignment with automatic digital synchronization using timestamp metadata. The system extracts timing information from video metadata and automatically aligns swings based on corresponding timestamps, eliminating the need for manual scrubbing and synchronization while achieving precise alignment of swing positions.
Solution Approach 2:
The system enables self-service automatic synchronization by using embedded timestamps in video metadata. The synchronization process occurs automatically without user intervention, with the system independently aligning videos based on their temporal information, thus saving operator time and reducing manual effort.
2Loss of information
If feedback is provided after video analysis, then swing assessment is possible, but feedback timeliness is delayed
Solution Approach 1:
The system performs preliminary actions by continuously analyzing swing mechanics during the recording process itself. Rather than waiting until after recording to analyze and provide feedback, the system proactively processes swing data in real-time, enabling immediate feedback delivery that maintains information completeness while eliminating delays.
Solution Approach 2:
The system maintains continuous analysis and feedback generation throughout the recording process. The useful action of swing analysis continues uninterrupted during video recording, ensuring that feedback information is generated continuously rather than in batches, thus providing timely feedback without sacrificing analytical thoroughness.
3Quantity of substance
If multiple swing videos are recorded and analyzed, then comprehensive training data is obtained, but processing complexity and computational load increase
Solution Approach 1:
The system segments the comprehensive training data processing into manageable units by analyzing each swing individually using timestamp-based identification. Each swing is processed as a discrete unit with its own temporal markers, allowing the system to handle multiple videos systematically without being overwhelmed by overall complexity, while still building comprehensive training datasets.
