Golf Club Head Performance Selection via Impact Probability Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring the performance of golf club heads, particularly for golfers with higher handicaps, are inadequate as they do not accurately represent the overall performance due to ball impacts occurring at various locations on the striking face, which the characteristic time (CT) value alone cannot capture.
Innovation Solution
A method involving the creation of a model golf club head with structural attributes, generating data on coefficient of restitution (COR) and impact probability, calculating an expected overall performance value, and modifying the club head's attributes to optimize performance based on this data, while ensuring compliance with regulatory standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If characteristic time (CT) measurement is used to evaluate golf club head performance, then regulatory compliance is achieved, but measurement precision deteriorates for higher handicap golfers who impact balls at various face locations
Solution Approach 1:
The striking face is divided into multiple discrete locations, with CT measurements taken at each location individually. This segmentation allows the system to capture the variability in performance across different impact zones rather than relying on a single centralized measurement point.
Solution Approach 2:
Different regions of the striking face are evaluated with their own specific CT values and performance characteristics. The system assigns localized performance data to each face location, enabling tailored club head design where different areas have optimized properties for their specific function.
2Measurement precision
If multiple structural attributes are modified to optimize expected overall performance value, then performance accuracy improves, but device complexity increases
Solution Approach 1:
The system modifies multiple structural parameters of the club head including face thickness, material composition, and geometric configuration at different locations. By systematically varying these parameters and evaluating their impact on expected overall performance value, the design process optimizes multiple attributes simultaneously while managing complexity through structured analysis.

Function Achieved in This Case
This approach allows for a more accurate assessment and selection of golf club heads tailored to individual golfer needs, improving performance by adjusting the club head's structure to enhance coefficient of restitution where it is most needed, thus providing a better representation of real-world impact scenarios.
