Golf Club Head Center of Gravity Adjustment via Crown Sole Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club head designs lack sufficient flexibility in positioning the center of gravity, limiting design freedom and performance, especially in achieving high ball flight trajectories without altering the center of gravity's position in other directions.
Innovation Solution
A hollow golf club head structure featuring a crown thick part, sole thick part, and a thinner back end, where the crown and sole thick parts overlap to form an elongated overlap part, allowing for adjustable weight distribution and increased moment of inertia, enabling greater freedom in designing the center of gravity's position without changing its direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the crown thick part and sole thick part are separated by the back end, then the center of gravity position can be adjusted in the vertical direction, but the structural complexity increases
Solution Approach 1:
The club head is divided into functionally independent thick parts: crown thick part, sole thick part, and back end, allowing separate positioning and weight distribution control. This segmentation enables independent adjustment of center of gravity height while maintaining overall structural integrity through the hollow body design.
2Strength
If the crown thick part and sole thick part overlap to form an elongated overlap part, then the moment of inertia increases, but the manufacturing complexity increases
Solution Approach 1:
The crown thick part and sole thick part are merged in the horizontal direction to form an elongated overlap part that extends along the crown-sole direction. This merging creates a continuous weight distribution pattern that maximizes moment of inertia while being formable through conventional casting or molding processes.
3Adaptability or versatility
If the back end is made thinner than the thickest portion of the thick parts, then the weight distribution flexibility increases, but the structural strength may decrease
Solution Approach 1:
Different regions of the club head are given different thickness qualities: the crown and sole thick parts are made thicker for weight concentration and moment of inertia, while the back end is made thinner for weight distribution flexibility. This local quality differentiation optimizes both strength and adaptability by placing material where it is most needed for each functional requirement.

AI summary
A golf club head includes a hollow structure defined by a face, a crown, a sole, and a back. The crown includes a crown thick part on the back side, and the sole includes a sole thick part on the back side. The back includes a back end thinner than the thickest portion of each of the crown thick part and the sole thick part. The crown thick part and the sole thick part are separated by the back including the back end. The crown thick part and the sole thick part lie over and cover at least part of each other to form an overlap part extending in a toe-heel direction in a view in a crown-sole direction.
