Variable Groove Geometry for Consistent Golf Ball Striking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads with grooves struggle to consistently manage ball speed and roll-out distance across different strike locations on the club face, leading to inconsistent performance.
Innovation Solution
The design and manufacturing of golf club heads with grooves that vary in depth, length, and width across the ball striking face, creating a central strike zone that mimics the shape of a golf ball, thereby improving ball striking properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If grooves are made with uniform depth, length, and width across the club face, then manufacturing is simple, but ball speed and roll-out distance become inconsistent across different strike locations
Solution Approach 1:
The patent applies local quality by varying groove depth, length, and width at different locations on the club face. Specifically, grooves in the central region have different dimensions than grooves at the periphery, with the central grooves having greater depth and length to compensate for lower strike efficiency in that region. This localized variation in groove geometry ensures consistent ball speed and roll-out distance across all strike locations on the club face.
Solution Approach 2:
The patent transitions from uniform two-dimensional groove patterns to three-dimensional variable geometry grooves. By introducing variations in depth (vertical dimension), length, and width across the club face surface, the design creates a ball striking face that mimics the spherical shape of a golf ball, thereby achieving consistent performance across different strike zones through dimensional complexity.
2Reliability
If grooves are made deeper and more prominent, then ball striking performance improves, but manufacturing complexity and cost increase
Solution Approach 1:
The patent employs parameter changes by systematically varying groove depth, length, and width parameters across different regions of the club face. The central grooves have greater depth and length parameters, while peripheral grooves have reduced parameters. This graduated parameter variation achieves reliable ball striking performance while allowing for controlled manufacturing through standardized progression patterns.
