Squash Racquet 3D Motion Sensing for Real-Time Training Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Squash training lacks real-time feedback and quantitative measures for evaluating racquet motions, relying heavily on expensive on-site coaches and post-training video analysis.
Innovation Solution
A squash training system equipped with a sport sensor attached to a racquet to detect 3D motion data, which is processed by a terminal device to provide instant graphical feedback on performance metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a coach is hired for squash training, then training quality and guidance are improved, but training cost increases
Solution Approach 1:
The system enables players to conduct self-training with automated feedback. The sensor attached to the racquet automatically detects swing motions, processes the data, and provides real-time feedback without requiring a coach's continuous presence, allowing players to independently evaluate and improve their techniques
Solution Approach 2:
The patent replaces the mechanical system of human coach observation and evaluation with an automated sensor-based system. The sport sensor detects racquet motion parameters objectively, and the processing system generates feedback, substituting human judgment with instrumental measurement and automated analysis
2Loss of information
If video recordings are used for training analysis, then a basis for analysis is provided, but real-time feedback is lost
Solution Approach 1:
The system implements real-time feedback by detecting racquet swing motions through the sensor and immediately processing the data to generate performance evaluations. This continuous feedback loop allows players to receive instant guidance on their technique during training sessions, enabling immediate correction and improvement
Solution Approach 2:
The patent replaces the passive video recording system with an active real-time detection system. Instead of recording motions for later review, the sport sensor continuously monitors racquet motion parameters and provides immediate automated feedback, transforming post-hoc analysis into real-time guidance
3Loss of information
If traditional coach-based training is used, then qualitative instructions are provided, but quantitative measurement is lacking
Solution Approach 1:
The system replaces subjective human observation with objective instrumental measurement. The sport sensor quantitatively detects racquet motion parameters such as swing speed, angle, and acceleration, providing precise numerical data that complements and validates qualitative coaching instructions
Solution Approach 2:
The system combines both qualitative and quantitative assessment functions in a single integrated platform. It provides automated technical feedback based on measured parameters while also offering performance evaluation and training guidance, serving multiple training needs simultaneously

AI summary
A squash training system includes a sport sensor. The sport sensor includes a sensing unit configured to detect a motion of a racquet and generate three-dimensional (3D) motion data associated with the motion. The sport sensor also includes a memory configured to store the 3D motion data and a communication interface configured to transmit the 3D motion data to a terminal device. The squash system also includes at least one processor configured to receive the 3D motion data from the sport sensor and determine, based on the 3D motion data, at least one characteristic associated with the motion. The processor is also configured to render a graphical representation of the characteristic on a display.
