Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional coaching methods are used, then coaching is provided by human coaches, but it lacks real-time data-driven analysis and immediate feedback
Solution Approach 1:
The patent replaces the mechanical system of human coach observation and analysis with an automated AI-based computer vision system. Multiple cameras capture player movements, and AI algorithms automatically analyze biomechanics, ball dynamics, and racket positioning in real-time, eliminating the need for manual measurement and analysis by human coaches.
Solution Approach 2:
The system enables self-service coaching by providing players with immediate automated feedback through mobile devices. The AI system independently performs data collection, analysis, and feedback delivery without requiring human coach intervention, allowing players to receive personalized coaching insights anytime during practice sessions.
2Ease of operation
If professional coaches are used, then personalized guidance is provided, but it is expensive and not sustainably available
Solution Approach 1:
The patent creates a digital copy of professional coaching capabilities through AI algorithms that replicate expert analysis. The system captures coaching knowledge in software form, allowing unlimited replication and distribution at minimal marginal cost, making professional-level coaching accessible to anyone with a smartphone without the high costs associated with hiring actual coaches.
Solution Approach 2:
The system serves multiple functions simultaneously: it acts as a coach, analyst, feedback provider, and training planner all in one automated platform. This multi-functionality consolidates what previously required multiple human professionals into a single affordable system that can serve unlimited users.
3Loss of information
If comprehensive real-time analysis is implemented, then performance feedback is improved, but device complexity increases
Solution Approach 1:
The patent segments the complex analysis task into distinct functional modules: camera systems for data capture, AI algorithms for biomechanical analysis, ball tracking subsystems, and feedback generation components. Each module handles a specific aspect of analysis independently, making the overall complex system manageable and scalable while maintaining comprehensive information collection.
Solution Approach 2:
The system introduces mobile devices as intermediaries between the complex analysis system and the player. The AI system processes comprehensive data and delivers simplified, actionable insights through familiar smartphone interfaces, mediating between raw data complexity and user-friendly feedback delivery.
