Variable Groove Golf Club Heads for Consistent Ball Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf club heads lack effective grooves that provide consistent ball speed and roll-out distance across different striking locations, leading to inconsistent performance for various putting styles and strokes.
Innovation Solution
The design of golf club heads with variable depth and width grooves that progressively change from the top rail to the sole, featuring elliptical or curved grooves and protrusions, which absorb kinetic energy uniformly across the striking face, optimizing ball speed and roll-out distance regardless of striking location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional parallel grooves are used on the club face, then the club can clear water, sand, grass and debris between the ball and club face, but the ball speed and roll-out distance become inconsistent across different striking locations
Solution Approach 1:
The patent applies local quality by varying the groove depth and width across different regions of the club face. Grooves near the perimeter have different dimensions than grooves near the center, allowing each region to optimize performance for its specific striking location. This creates consistent ball speed and roll-out distance across all striking points while accommodating different putting styles.
Solution Approach 2:
The patent employs asymmetry by positioning grooves at non-uniform intervals and using elliptical or curved shapes instead of conventional parallel straight grooves. The grooves are strategically placed to account for the different dynamics of various putting strokes, creating an asymmetric pattern that adapts to multiple putting styles while maintaining consistent performance.
2Ease of manufacture
If uniform depth and width grooves are used across the entire club face, then manufacturing is simplified, but performance consistency varies with striking location
Solution Approach 1:
The patent implements local quality with varying groove depths and widths at different club face locations. The manufacturing process is designed to accommodate these variations through specialized grooving tools and programming that can precisely control groove dimensions at each location, ensuring optimal performance while managing manufacturing complexity.
3Reliability
If elliptical or curved grooves are used instead of straight parallel grooves, then kinetic energy is absorbed uniformly across the striking face, but groove manufacturing complexity increases
Solution Approach 1:
The patent applies curvature by using elliptical and curved groove shapes instead of straight parallel grooves. These curved configurations are specifically designed to absorb kinetic energy uniformly across the striking face, with the curvature radii and orientations optimized to distribute energy absorption evenly regardless of striking location.
Solution Approach 2:
The patent utilizes parameter changes by systematically varying groove depth, width, curvature radius, and spacing across different regions of the club face. These parameter variations are programmed into the manufacturing process to achieve uniform kinetic energy absorption while managing the complexity of creating non-uniform groove patterns.
