Magnetic Trajectory Overlay for Golf Training Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for analyzing the movement of sports equipment in ball sports, such as golf, are inadequate for providing real-time feedback on motion dynamics, especially during slower movements like putting, leading to unsatisfactory training outcomes due to the inability to detect and correct poor strategic techniques.
Innovation Solution
A method and apparatus that utilize a head-mounted display and tracking module to calculate and superimpose an ideal trajectory of sports equipment onto the real environment, providing simultaneous feedback on the ideal and actual movements, allowing users to recognize deviations and improve their technique.

Engineering Contradiction Analysis
1Measurement precision
If traditional video recording and bioanalysis methods are used to analyze putting movements, then the analysis can be performed with simple equipment, but the dynamic aspects of the putting stroke cannot be sufficiently detected due to the speed of execution and high precision requirements
Solution Approach 1:
The patent replaces traditional mechanical video recording and bioanalysis systems with a magnetic field-based detection system. Magnetic field sensors detect the position and movement of the golf club and ball through the magnetic field interactions, providing precise real-time data on motion dynamics without the limitations of visual observation methods.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary medium between the sports equipment and the detection system. By embedding magnetic elements in the golf club and ball, and using magnetic field sensors in the environment, the system indirectly measures motion parameters with high precision through magnetic field variations rather than direct mechanical or visual measurement.
2Productivity
If slower movements like putting are practiced repeatedly to improve technique, then muscle memory can be developed, but poor strategic motion techniques are learned and reinforced unknowingly
Solution Approach 1:
The patent implements real-time feedback by continuously detecting the actual trajectory of the golf club and ball using magnetic field sensors and comparing it with the ideal trajectory calculated by the system. This feedback is provided to the golfer during practice, enabling immediate awareness of technique quality and strategic motion errors, preventing reinforcement of poor habits.
Solution Approach 2:
The patent calculates the ideal trajectory in advance based on environmental parameters (green slope, grain, speed) before the golfer executes the putt. This preliminary determination of the correct motion path provides a reference for the golfer to compare against their actual execution, enabling proactive technique correction.
3Ease of operation
If training aids are used to provide feedback on motion sequences, then learning can be enhanced, but the complexity of the training system increases
Solution Approach 1:
The patent enables the training system to automatically detect, analyze, and provide feedback on motion techniques without requiring constant intervention from coaches or complex manual analysis. The magnetic field detection system and trajectory comparison algorithms self-service the analysis function, simplifying the user interface while maintaining high analytical capability.
