Solution Overview

Problem

Golf club heads have increased in size and mass, making it challenging to maintain performance while optimizing mass distribution, as existing designs struggle to balance density and weight distribution effectively.

Innovation Solution

Incorporating a hosel insert made of a lower density material, such as magnesium, within the golf club head, which reduces mass at the hosel region and allows for redistribution of mass to optimize the club's performance characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If golf club heads are increased in volume and size to improve performance, then the mass of the golf clubs increases, but this makes it challenging to maintain performance and optimize mass distribution

Engineering Contradiction:
Improvegolf club head volumeVSAvoidgolf club head mass
Core Design Contradiction:
Volume of moving objectVSWeight of moving object

Solution Approach 1:

The patent applies local quality by using different density materials in different regions of the golf club head. Specifically, lower density materials are used in certain areas while more dense materials are used in other areas, allowing the club head to achieve desirable mass distribution characteristics without uniformly increasing overall mass throughout the entire club head volume

Inventive Principle:
Principle #3Local quality

2Weight of moving object

If hosel insert made of lower density material is used to reduce mass at hosel region, then mass distribution is improved, but structural integrity must be maintained

Engineering Contradiction:
Improvehosel region massVSAvoidhosel region structural integrity
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The patent employs composite materials by combining lower density materials (such as magnesium) with more dense materials in the hosel insert construction. This composite approach allows the hosel region to achieve reduced mass while maintaining the necessary structural integrity through the synergistic combination of materials with different density and strength properties

Inventive Principle:
Principle #40Composite materials
