Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If stationary multi-camera systems are used for motion capture, then measurement precision is improved, but device complexity and portability are worsened
Solution Approach 1:
The system divides the motion capture functionality into separate portable camera units with motion capture elements, allowing the complex measurement system to be segmented into manageable, mobile components that can be deployed flexibly without requiring a fixed multi-camera installation
Solution Approach 2:
The patent replaces the mechanical stationary multi-camera system with wireless motion capture elements and portable cameras that transmit data electronically, eliminating the need for fixed mechanical installations while maintaining measurement precision through wireless data transmission and digital processing
2Productivity
If motion capture data is collected and stored for data mining, then productivity and insights are improved, but loss of time for data processing increases
Solution Approach 1:
The system performs preliminary processing and organization of motion capture data during collection, storing data in structured formats that are ready for immediate analysis, thereby reducing the time required for subsequent data processing and enabling faster sports performance insights
3Ease of operation
If portable wireless motion capture elements are used, then ease of operation and portability are improved, but measurement precision may be worsened
Solution Approach 1:
The portable motion capture elements include sensors that provide real-time feedback on their own positioning and operational status, allowing the system to automatically adjust and maintain measurement precision while retaining portability and ease of operation
Data Source
AI summary
A broadcasting system for broadcasting images with augmented motion data, which includes at least one camera, a computer and a wireless communication interface. The system obtains data from motion capture elements, analyzes data and optionally stores data in database for use in broadcasting applications, virtual reality applications and/or data mining. The system also recognizes at least one motion capture data element associated with a user or piece of equipment, and receives data associated with the motion capture element via the wireless communication interface. The system also enables unique displays associated with the user, such as 3D overlays onto images of the user to visually depict the captured motion data. Ratings, compliance, ball flight path data can be calculated and displayed, for example on a map or timeline or both. Furthermore, the system enables performance related equipment fitting and purchase.
