Multi-material Golf Club Head Mass Redistribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club designs fail to effectively reduce unnecessary mass while maintaining the sound and feel, as lightweight materials used to create discretionary mass often degrade the acoustic signature and tactile experience.
Innovation Solution
A golf club head design featuring a multi-layered structure with a titanium base layer and a lightweight cover layer, where the base layer has a plurality of cutouts and the lightweight cover layer has an Internal Exposure Percentage of 15% to 60%, providing structural rigidity and discretionary mass distribution without compromising sound and feel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If lightweight materials are used to replace metallic materials at various portions of the golf club head, then discretionary mass is increased, but the sound and feel of the golf club significantly degrades
Solution Approach 1:
The patent applies local quality by using different materials in different portions of the golf club head. Specifically, lightweight materials (such as graphite composite) are used in non-critical areas like the crown and sole, while traditional metallic materials are retained in critical areas that directly affect sound and feel during impact. This selective material distribution allows the design to maximize discretionary mass while preserving the desired acoustic and tactile characteristics in key regions.
2Weight of moving object
If more lightweight material is used to increase discretionary mass, then mass savings increase, but the structural integrity and sound preservation become compromised
Solution Approach 1:
The patent employs parameter changes by carefully controlling the thickness, density, and distribution parameters of lightweight materials used in the golf club head. By adjusting these parameters, the design achieves optimal mass reduction while maintaining sufficient structural integrity. The lightweight materials are applied with specific thickness ranges and structural configurations that preserve strength in critical load-bearing areas while maximizing weight savings in non-critical portions.

AI summary
A golf club head made out of multi-material is disclosed herein. More specifically, the golf club head in accordance with the present invention has at least a portion of the body of the golf club head that is further comprised out of a base layer and a lightweight cover layer. The base layer may have a plurality of cutouts to help reduce unnecessary mass and the lightweight cover layer may be made out of an ultra-lightweight material to further reduce the unnecessary mass. The resulting golf club head may generally have a deep CG wherein the CG-B location is about 37 mm, and a CG-C location is greater than about 30 mm.
