Variable Groove Golf Putter Face Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf club heads lack effective grooves that can consistently improve ball speed and roll-out distance across various striking locations on the putter face, leading to inconsistent performance for different golfers based on their putting styles.
Innovation Solution
The design of golf club heads with grooves that vary in depth, width, and cross-sectional shape from the toe end to the heel end and from the top rail to the sole, creating a central strike zone that mimics the shape of a golf ball, allowing for a consistent ball striking experience regardless of the impact location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional grooves are used on golf club heads, then manufacturing is simple, but ball speed consistency and roll-out distance are poor across various striking locations
Solution Approach 1:
The groove design implements local quality by varying groove depth, width, and cross-sectional shape at different locations on the putter face. Specifically, grooves are deeper and wider at the periphery (toe and heel ends, top rail and sole) and shallower and narrower toward the center, creating location-specific groove characteristics that optimize ball interaction across the entire striking surface.
Solution Approach 2:
The invention transitions from conventional uniform grooves to three-dimensional variable grooves by introducing depth variations and cross-sectional shape changes. The grooves extend into the putter face material with varying depths (e.g., 0.003-0.020 inches) and cross-sectional profiles (V-shaped, U-shaped, or squared), adding dimensional complexity that enhances ball speed consistency.
2Reliability
If grooves vary in depth and shape across the putter face, then ball speed consistency improves, but manufacturing precision requirements increase
Solution Approach 1:
The design employs parameter changes by systematically varying groove depth, width, and cross-sectional shape parameters across different locations on the putter face. Specific parameters include groove depth (0.003-0.020 inches), width (0.020-0.060 inches), and cross-sectional profiles (V-shaped with 60-90 degree angles, U-shaped, or squared), creating a graduated pattern that balances performance with manufacturability.
3Reliability
If grooves are deeper and more pronounced, then ball speed consistency improves, but ball roll-out distance increases
Solution Approach 1:
The groove design implements local quality by creating a gradient pattern where peripheral grooves (at toe and heel ends, top rail and sole) are deeper and more pronounced to generate spin and control ball roll-out, while central grooves are shallower to maintain ball speed consistency without excessive roll-out. This location-specific variation optimizes the balance between spin generation and distance control.
