Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional handling evaluation techniques are used, then the evaluation process is simple, but the measurement precision of handling quality is insufficient
Solution Approach 1:
The sport ball is divided into multiple sensor zones with different types of sensors (pressure sensors, force sensors, acceleration sensors, gyro sensors) positioned at specific locations to measure different aspects of handling, enabling comprehensive qualitative assessment through segmented measurement points
Solution Approach 2:
The sensor system is designed to perform multiple functions including detecting grip events, measuring force vectors, tracking ball movement, and evaluating various handling techniques (catching, throwing, dribbling) across different sports ball types, making the system universally applicable
2Measurement precision
If multiple pressure sensors are added to the sport ball, then the measurement precision of grip events improves, but the device complexity increases
Solution Approach 1:
Pressure sensors are segmented into specific zones on the ball surface corresponding to common grip locations, with each zone's sensors working together to detect and characterize grip events with high precision
Solution Approach 2:
Multiple sensor types (pressure, force, acceleration, gyro) are merged into an integrated sensor system that processes data collectively to evaluate handling techniques, reducing overall system complexity through unified data processing
3Measurement precision
If force values from multiple sensors are processed, then the handling evaluation accuracy improves, but the processing complexity increases
Solution Approach 1:
The processor is designed with multi-functional capabilities to handle various sensor data types, calculate multiple handling metrics (grip strength, timing, technique), and provide comprehensive evaluation across different sports and handling scenarios through unified processing algorithms
