Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sports training aids fail to effectively monitor and analyze critical swing metrics in sports such as golf, baseball, tennis, and hockey, making it difficult for athletes to identify and correct flaws in their swing techniques.
Innovation Solution
A device equipped with motion sensors, microprocessors, grip pressure sensors, and optional EEG sensors that computes and displays swing metrics like contact orientation, swing path, and timing, categorizing swings into specific flight patterns to provide immediate feedback for correction, along with adjustable metronome output for tempo synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a device monitors and analyzes multiple swing metrics simultaneously, then the comprehensiveness of swing analysis is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple sensors (accelerometers, gyroscopes, magnetometers, force sensors, EEG sensors) and computational functions into a single integrated device that attaches to the sports striking object. This merging allows comprehensive monitoring of multiple swing metrics simultaneously while managing device complexity through integration rather than separate components.
Solution Approach 2:
The device is designed to be universal across multiple sports (golf, baseball, tennis, hockey) by monitoring various swing metrics (contact orientation, swing path, timing, velocity, acceleration) that apply to all these sports. The same device structure and sensor array can analyze different sports swings, making the system multi-functional and reducing the need for sport-specific equipment.
2Loss of information
If the device provides detailed swing metric data and feedback, then the effectiveness of swing correction is improved, but the information processing complexity increases
Solution Approach 1:
The device implements real-time feedback by displaying swing metric data on LED or LCD screens and wirelessly transmitting information to external devices like smartphones. The system provides immediate feedback on contact orientation, swing path, and timing, allowing athletes to identify and correct flaws during training sessions.
Solution Approach 2:
The patent uses microprocessors as intermediaries to collect raw sensor data, process it through algorithms, and convert it into meaningful swing metrics. The microprocessor acts as a mediator between the complex sensor array and the user-friendly display interface, simplifying the information processing complexity while maintaining comprehensive feedback.
3Measurement precision
If the device includes multiple sensor types for comprehensive monitoring, then the measurement accuracy is improved, but the device weight increases
Solution Approach 1:
The device places different sensor types (accelerometers for linear acceleration, gyroscopes for angular velocity, magnetometers for orientation, force sensors for grip pressure) in specific locations within the device structure. Each sensor type is positioned to optimize its measurement capability for specific swing metrics, achieving high measurement accuracy while managing overall device weight through strategic sensor placement.

AI summary
A sports swing training device is attachable to a sports striking-object, such as a golf club, tennis racket, or baseball bat, and uses multiple motion sensors, including accelerometers, gyroscopes and magnetometers, in conjunction with one or more microprocessors and device displays, to measure and display various swing metrics and to project flight patterns resulting from each swing. Swing data are displayed in graphic and/or indicia format, on the device's displays and are wirelessly transmitted to the displays of one or more external devices, such as smart phones or tablet computers. The projected flight patterns reveal flaws in the swing so as to promote corrective adjustments by the athlete.
