Golf Club Head Crown Segmentation for CG Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club heads do not effectively optimize the center of gravity (CG) and moment of inertia (MOI) to enhance launch angle, spin rate, and direction consistency across various golf swings, leading to inconsistent ball flight.
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 a face portion that can be integral or separate, enhancing structural integrity and aerodynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the crown portion is made with thin sections to reduce weight, then the center of gravity is lowered and weight is reduced, but the structural strength may be compromised
Solution Approach 1:
The crown portion is divided into multiple thin sections or layers rather than being a single thick structure. This segmentation reduces overall weight while maintaining structural integrity through the distributed arrangement of multiple thinner elements that collectively provide the necessary strength.
Solution Approach 2:
The crown portion utilizes composite material construction, combining multiple materials with different properties. This allows the thin sections to achieve both weight reduction and enhanced structural strength by leveraging the complementary characteristics of different materials in a composite structure.
2Strength
If integral ribs are added to the crown portion for structural reinforcement, then structural strength is improved, but device complexity increases
Solution Approach 1:
The integral ribs are merged with the crown portion as a single integrated structure rather than being separate components. This combining approach provides structural reinforcement while minimizing complexity by eliminating the need for additional assembly steps or separate parts.
Solution Approach 2:
The integral ribs are strategically positioned in specific locations within the crown portion where structural reinforcement is most needed. This local quality approach applies reinforcement only where necessary rather than uniformly throughout, optimizing strength while controlling complexity.
3Reliability
If the center of gravity is lowered to improve launch angle consistency, then ball flight predictability is enhanced, but the club head design complexity increases
Solution Approach 1:
The center of gravity is lowered by modifying the vertical dimension of the club head design, specifically through the thin-section crown portion that extends downward. This dimensional change achieves CG optimization without requiring complex adjustments in other dimensions or aspects of the design.
Solution Approach 2:
The design utilizes parameter changes in the crown portion geometry, specifically varying the thickness and shape parameters to strategically position the center of gravity. By adjusting these geometric parameters, the CG is optimized for consistent launch angles without fundamentally redesigning the entire club head structure.

AI summary
Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having a front portion, a rear portion, a toe portion, a heel portion, a top portion, and a bottom portion. The front portion may include a front pocket defined by an interior wall. A face portion may be positioned in the front pocket. The material of the face portion may have a substantially higher yield strength than the material of the interior wall. Other examples and embodiments may be described and claimed.
