Real-Time Motion Feedback Sensor Unit for Sports Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Athletes and coaches face challenges in correcting complex movements like golf swings and other sports techniques due to the lack of real-time feedback from traditional video recording methods, which are time-consuming and require cognitive processing, and do not effectively engage emotional or reflexive learning.
Innovation Solution
A lightweight sensor unit attached to the body provides real-time feedback by tracking motion and comparing it to a reference track, using a small chip motion tracking device to detect deviations and trigger immediate stimuli, allowing for subconscious learning of new movement patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional video recording methods are used to analyze and correct athlete movements, then detailed motion analysis is possible, but real-time feedback is not provided and significant time is required for review and cognitive processing
Solution Approach 1:
The patent replaces traditional video recording and human cognitive analysis with an automated sensor-based measurement system. Motion sensors attached to the athlete's body and reference objects automatically capture position data, while a processor real-time computes motion parameters and compares them against target values, eliminating the need for video review and human analysis time.
Solution Approach 2:
The system performs self-analysis by automatically comparing measured motion parameters with target parameters stored in memory. The processor independently determines deviations without requiring external human intervention, and the feedback device automatically provides correction guidance, making the entire analysis and feedback process autonomous and immediate.
2Loss of information
If video recording equipment is used by coaches to help improve athlete technique, then motion data is captured, but the feedback process is time-consuming and requires extensive cognitive processing by both coach and athlete
Solution Approach 1:
The patent replaces complex video recording and manual analysis systems with automated sensor devices that directly measure motion parameters. The sensors capture position, velocity, and acceleration data electronically, and the processor automatically computes motion characteristics and compares them with target values, eliminating the need for video playback and human cognitive processing.
Solution Approach 2:
The system implements real-time feedback by continuously monitoring motion parameters, comparing them against stored target parameters, and immediately providing feedback through a feedback device when deviations are detected. This closed-loop feedback system enables athletes to receive instant correction guidance without the delays inherent in video review processes.
3Loss of time
If a comprehensive motion tracking system with multiple sensors is implemented, then accurate real-time feedback is achieved, but device complexity and cost increase
Solution Approach 1:
The patent divides the motion tracking system into separate functional modules: motion sensors attached to the athlete's body, reference object sensors, a processor for computation, and a feedback device. Each module performs a specific function, allowing the system to achieve comprehensive real-time monitoring while maintaining modularity and reducing overall system complexity through functional decomposition.
