Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack a convenient and accurate method to monitor and record player performance metrics during team sports, such as soccer, basketball, and football, limiting the ability to gauge improvement and identify strengths and weaknesses.
Innovation Solution
The development of athletic performance monitoring systems that include sensor systems integrated into apparel, footwear, or equipment, capable of tracking movement speed, ball possession, and other performance metrics, with data processing and output devices providing user-perceptible feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If specialized gym equipment systems are used to track athletic performance, then measurement precision is improved, but ease of operation deteriorates because the system is confined to specialized equipment within gym walls
Solution Approach 1:
The patent extracts the measurement functionality from fixed gym equipment and integrates it into portable wearable devices that can be used anywhere. Sensors are embedded in clothing, shoes, or handheld devices, allowing athletes to track performance metrics outside traditional gym environments while maintaining measurement precision.
Solution Approach 2:
The system becomes universal by enabling performance tracking across multiple locations and activities. The wearable sensors can monitor various athletic metrics (speed, distance, heart rate, etc.) whether the athlete is exercising in a gym, outdoors, or during team sports, eliminating the confinement to specialized equipment.
2Measurement precision
If comprehensive sensor systems are integrated into apparel and equipment for team sports monitoring, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system divides the monitoring function into separate modular sensor units distributed across different locations (apparel, footwear, equipment). Each sensor package independently measures specific parameters, and the data is aggregated by a central processing system, reducing the complexity of any single component while achieving comprehensive measurement.
Solution Approach 2:
The patent introduces wireless communication modules as intermediaries between the distributed sensors and the central processing system. This allows sensors to be placed in multiple locations without creating complex wiring, as data is transmitted wirelessly to a central unit for processing and analysis.

AI summary
Systems, apparatuses, and methods for determining when an athlete is in possession of a ball by analyzing image data are provided. A camera is worn by an athlete and is turned on when the athlete is in proximity of a ball. The camera is used to generate an image of a ball. The size of the ball is determined and compared to a threshold. The athlete is considered to be in possession of the ball when the size of the image exceeds the threshold.
