Golf Club Head Crown Segmentation for CG and Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club heads face challenges in optimizing the center of gravity (CG) and moment of inertia (MOI) to enhance golf ball launch angle, spin rate, and direction, which vary significantly based on the type of golf swing, leading to inconsistent performance.
Innovation Solution
The design incorporates a golf club head with a body portion made from materials like aluminum, magnesium, or titanium, featuring a crown portion with thin sections and integral ribs for weight reduction and structural reinforcement, along with a protruding portion to lower the CG and adjust the MOI, enhancing structural integrity and aerodynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the crown portion is made thinner to lower the center of gravity, then the launch angle and spin rate improve, but the structural integrity and stiffness of the club head deteriorate
Solution Approach 1:
The crown portion is divided into multiple regions with different thicknesses - thin portions for weight reduction and CG lowering, and thick portions for structural support and stiffness. This segmentation allows simultaneous optimization of weight distribution and structural integrity without compromising either goal.
Solution Approach 2:
Different regions of the crown portion are assigned different thickness qualities - thinner regions where weight reduction is prioritized (to lower CG) and thicker regions where structural strength is prioritized. This local differentiation resolves the contradiction by applying the right thickness in the right location.
2Reliability
If weight ports are added to adjust center of gravity and moment of inertia, then shot consistency improves, but the device complexity increases
Solution Approach 1:
The club head is segmented into functional zones including weight port regions, thin portions, and thick portions, each serving specific purposes. This segmentation enables precise control of CG and MOI while maintaining manufacturing feasibility through systematic design.
Solution Approach 2:
The design utilizes adjustable parameters such as weight port size, position, and number of ports to fine-tune CG and MOI values. This parametric approach allows optimization of shot consistency without requiring fundamental redesigns, thereby limiting complexity increase.

AI summary
Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a method of manufacturing a golf club head includes providing a body portion having a front portion with a front opening. A front pocket portion is welded to the front portion to close the front opening and form a first cavity. A polymer insert is positioned within the front pocket, the polymer insert occupying less than a total available space within the front pocket portion. A face portion is welded to the front pocket portion to close the front pocket portion and form a second cavity having a volume less than a volume of the first cavity. Other examples and embodiments may be described and claimed.
