Golf Club Head Crown Segmentation for Weight and Strength

Solution Overview

Problem

Current golf club heads lack optimal design features to consistently enhance distance and direction of golf ball travel, as they fail to effectively manage center of gravity (CG) and moment of inertia (MOI) across various golf swings.

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, which can be attached to a body portion with a forward portion extending to enhance impact resistance and distribute force evenly.

Engineering Contradictions & Design Principles

VSEngineering 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 structural strength may be compromised

Engineering Contradiction:

Core Design Contradiction:

Weight of moving objectVSStrength

Solution Approach 1:

The crown portion is divided into multiple regions with different thicknesses - thin sections for weight reduction and thicker regions with integral ribs for structural reinforcement. This segmentation allows simultaneous optimization of weight and strength in different areas of the same component.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the crown portion have different thickness characteristics - thin sections in areas where weight reduction is prioritized and thicker sections with integral ribs in areas requiring structural strength. This local variation in quality resolves the contradiction between weight reduction and strength maintenance.

Inventive Principle:

Principle #3Local quality

2Strength

If the forward portion extends further to enhance impact resistance, then force distribution is improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The forward portion is merged with the crown portion to form an integrated structure. This combining of components simplifies the overall device complexity while maintaining enhanced impact resistance and force distribution capabilities through the extended forward geometry.

Inventive Principle:

Principle #5Merging (Combining)

3Object-affected harmful factors

If materials like aluminum, magnesium, or titanium are used to reduce weight, then aerodynamic drag is reduced, but manufacturing precision requirements increase

Engineering Contradiction:

Core Design Contradiction:

Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The patent employs lightweight materials such as aluminum, magnesium, or titanium that reduce overall weight and aerodynamic drag. These materials are selected and processed to achieve the desired balance between aerodynamic performance and manufacturability, addressing the contradiction between drag reduction and precision requirements.

Inventive Principle:

Principle #40Composite materials
