Golf Club Fitting System Using Swing Data Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club fitting methods that utilize sensor data from monitoring devices have not been widely accepted or implemented, despite advancements in digital measurements, as they fail to accurately recommend suitable golf clubs based on a golfer's swing characteristics.
Innovation Solution
A computing device system that analyzes data from sensors attached to golf clubs, comparing attributes of the backswing and downswing to determine a skill value, and recommends suitable golf clubs from a group based on this analysis, using a network and server to process and transmit data for visualization and interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor data is collected and analyzed to determine swing characteristics, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system segments the swing analysis into distinct phases (backswing, downswing, impact) and measures specific attributes for each phase separately. This segmentation allows for precise measurement of swing characteristics while keeping the monitoring device relatively simple by focusing on key parameters rather than attempting to measure everything simultaneously.
Solution Approach 2:
The patent uses an intermediary computing device that processes sensor data and compares swing attributes against a database of professional golfer characteristics. This intermediary layer handles the complex analysis work, allowing the actual monitoring device to remain relatively simple while still achieving high measurement precision through sophisticated data processing.
2Manufacturing precision
If multiple swing attributes are compared to determine skill value, then manufacturing precision of recommendations is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing a database of swing characteristics from professional golfers and pre-defining the comparison framework for evaluating amateur swings. This preliminary preparation allows for accurate club recommendations without requiring complex real-time processing during the actual swing analysis, as the comparison criteria are already in place.
Solution Approach 2:
The patent transforms raw sensor data into meaningful swing attributes and compares these against established parameters from professional golfers. By changing the parameters from raw measurements to standardized swing characteristics, the system achieves precise recommendations while managing processing complexity through parameter transformation rather than raw data comparison.
3Loss of information
If sensor data is processed through a network and server, then information completeness is improved, but loss of time increases
Solution Approach 1:
The system implements partial action by initially providing club recommendations based on the most critical swing attributes without requiring complete analysis of all possible parameters. This allows for faster initial recommendations that can be refined later, reducing the time loss while still maintaining information completeness through iterative processing.

AI summary
A method for use in a system implementing a reference golf club, one or more sensors associated with the reference golf club, and a computing device. Using the computing device, the method comprises receiving from the one or more sensors swing data relating to a swing of the reference golf club, analyzing the swing data to determine recommended shaft parameter values for each of a plurality of shaft parameters using an algorithm, accessing a shaft database comprising actual shaft parameter values for each of the plurality of shaft parameters for each of a plurality of shafts, determining at least one shaft from the plurality of shafts based, at least in part, on a comparison between the recommended shaft parameter values and the actual shaft parameter values, transmitting information relating to the at least one shaft; and displaying the information on a display of the computing device.
