Golf Club Head Crown Segmentation for CG Optimization

Resolve Bottlenecks,
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 with different golf swings, 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

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the golf club head uses a traditional solid structure, then the structural strength is sufficient, but the weight distribution cannot be optimized to adjust CG and MOI

Engineering Contradiction:

ImproveCG and MOI consistencyVSAvoidstructural complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The crown portion is divided into multiple sections with different thicknesses (first through fourth sections) and includes integral ribs that segment the structure. This segmentation allows precise control of weight distribution to optimize CG and MOI while maintaining structural integrity through the rib reinforcements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different sections of the crown portion have different thicknesses (first section thicker than second, third thicker than fourth) to create localized weight variations. This local quality differentiation enables precise adjustment of CG position and MOI without requiring complete structural redesign.

Inventive Principle:

Principle #3Local quality

2Stability of the object's composition

If the crown portion is made with uniform thickness, then the manufacturing is simple, but the weight distribution cannot be optimized for CG and MOI adjustment

Engineering Contradiction:

Improveweight distributionVSAvoidmanufacturing complexity

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The crown portion is segmented into four distinct thickness sections with varying weights. This segmentation creates the necessary weight distribution for CG and MOI optimization while the sections are formed as an integral structure, simplifying manufacturing compared to assembling multiple separate pieces.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The crown portion is formed as a single integral structure combining multiple thickness sections and ribs into one piece. This merging of functions (weight adjustment, structural support, and manufacturing) into a single component achieves both weight distribution optimization and manufacturing efficiency.

Inventive Principle:

Principle #5Merging (Combining)

3Stability of the object's composition

If the club head uses thin sections for weight reduction, then the CG and MOI can be optimized, but the structural strength may be compromised

Engineering Contradiction:

ImproveCG and MOI optimizationVSAvoidstructural strength

Core Design Contradiction:

Stability of the object's compositionVSStrength

Solution Approach 1:

The crown portion is segmented into thin sections (second and fourth sections) for weight reduction and CG/MOI optimization, while simultaneously incorporating integral ribs that provide localized structural reinforcement. The ribs are strategically positioned to strengthen the thinner sections without adding significant weight.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different sections of the crown have different thicknesses to optimize weight distribution, with thinner sections (second and fourth) for weight reduction and thicker sections (first and third) combined with integral ribs for structural strength. This local quality variation achieves both weight optimization and structural integrity.

Inventive Principle:

Principle #3Local quality

4Adaptability or versatility

If the golf club head is designed for specific swing types, then the CG and MOI can be optimized for those swings, but the performance becomes inconsistent across different swing types

Engineering Contradiction:

Improveswing type adaptabilityVSAvoidperformance consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The crown portion incorporates four sections with different thicknesses and integral ribs, creating a balanced weight distribution that optimizes CG and MOI for multiple swing types simultaneously. This local quality differentiation across the crown structure provides versatility for different swings while maintaining consistent performance characteristics.

Inventive Principle:

Principle #3Local quality
