Wireless Golf Club Shot Tracking via RFID and Accelerometer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for analyzing and tracking golf shots are either cumbersome due to the use of wires in sensor-equipped golf clubs or lack comprehensive data storage and display capabilities, limiting their effectiveness and accessibility for golfers.
Innovation Solution
A system comprising golf clubs with transmitters and a receiver or wrist-worn GPS device that includes a display, GPS chipset, memory, short-range transceiver, processor, battery, and USB connection port, allowing for wireless data transmission and storage of shot tracking information for processing and display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If wires are used to transmit sensor data from the golf club, then data transmission is achieved, but the system becomes cumbersome and obtrusive to the golfer
Solution Approach 1:
The patent extracts the data transmission function from the wired connection and implements it through wireless technology. The sensor system transmits swing data, launch conditions, and shot information wirelessly to a receiver device, eliminating the physical wire that causes cumbersomeness while preserving complete data transmission capability.
Solution Approach 2:
The patent replaces the mechanical wired connection system with an electronic wireless transmission system. Instead of using physical wires to connect sensors to the receiver, the system uses electromagnetic signals for data transmission, thereby eliminating the mechanical constraint that obstructs golfer movement and comfort.
2Loss of information
If comprehensive data storage and display capabilities are added to the system, then analysis effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent merges the data storage, processing, and display functions into an integrated receiver device. This single unit combines memory for storing swing and shot data, a processor for analyzing launch conditions and performance metrics, and a display interface for presenting results to the golfer, thereby providing comprehensive capabilities without proportionally increasing overall system complexity.
Solution Approach 2:
The receiver device serves as an intermediary between the simple sensor/transmitter components on the golf club and the golfer's need for comprehensive data analysis. It handles all complex functions of data reception, storage, processing, and display, allowing the on-club components to remain relatively simple while still delivering comprehensive analytical capabilities to the user.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables golfers to automatically track and review their performance during and after a round, providing detailed data on launch conditions and swing diagnostics without the obstructions of wires, enhancing analysis and accessibility.
Implementation Method 1
The diagnostics of the golf club measure at least golf club speed using an accelerometer.
Implementation Method 2
The active RFID transponder transmits at least one signal containing data about the golf club
Data Source
AI summary
A system and method for shot tracking is disclosed herein. The system preferably includes a golf club, a receiver device and a server with a website. The golf club preferably includes an active RFID transponder, a power source and a shock switch. When the golf club strikes a golf ball, the shock switch closes thereby powering the RFID transponder which sends a signal to the receiver device for automatically tracking a golfer's round of golf. The data is then uploaded to the website for processing.
