Golf Club Head Face Thickness Zoning for Ball Speed Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads face challenges in balancing ball flight characteristics, structural integrity, and durability, as adjustments to improve one aspect often compromise others.
Innovation Solution
A golf club head design featuring a striking face with variable thickness, including a thick central portion and tapered heel and toe portions, along with strategically positioned weights, to enhance ball speed, launch angle, and uniformity while maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the striking face thickness is increased to improve structural integrity and durability, then ball speed and launch angle may be reduced
Solution Approach 1:
The striking face is designed with non-uniform thickness distribution, featuring a thick central portion for structural integrity and durability, while heel and toe portions have reduced thickness to allow greater flexure and improve ball speed. This local differentiation resolves the contradiction by optimizing each region's thickness according to its specific functional requirements rather than using a uniform thickness throughout.
Solution Approach 2:
The striking face is segmented into distinct thickness zones: a thick central portion and thinner heel/toe portions. This segmentation allows different regions to serve different functions - the central portion provides structural strength while the heel and toe portions provide flexibility for speed enhancement, thereby resolving the contradiction between strength and speed.
2Speed
If the striking face thickness is decreased to improve ball speed, then structural integrity and durability may be compromised
Solution Approach 1:
The striking face employs local quality variation with a thick central portion maintaining structural integrity while heel and toe portions have reduced thickness to enhance ball speed. This localized thickness optimization allows speed improvement in critical areas without compromising overall structural strength.
Solution Approach 2:
The striking face features asymmetric thickness distribution rather than uniform symmetry, with the central portion being thicker than the heel and toe portions. This asymmetric design optimizes performance by providing strength where needed (center) and flexibility where beneficial (edges), resolving the contradiction between speed and strength.
3Strength
If the striking face thickness is uniformly increased, then uniformity of ball speed across the face may deteriorate
Solution Approach 1:
The striking face uses local quality differentiation with a thick central portion and thinner heel/toe portions to achieve both structural integrity and uniform ball speed. The varied thickness distribution compensates for natural flexure patterns, ensuring consistent performance across different impact locations while maintaining overall strength.

AI summary
A golf club head includes a striking face having a substantially flat frontal striking surface, and having a lower leading edge and an opposite upper topline edge; a topline extending rearward from the upper topline edge; a sole extending rearward from the lower leading edge; a support bar protruding rearwardly from the striking face; an upper cavity at least partially surrounded by the topline, an upper section of the striking face, and the support bar; and a lower cavity at least partially surrounded by the support bar, a lower section of the striking face, and the sole, wherein the lower section of the striking face includes a heel portion, a toe portion, and a thick portion between the heel portion and the toe portion, and wherein a thickness of the thick portion is greater than a thickness of the heel portion and a thickness of the toe portion.
