Multi-Component Golf Club Head with Lightweight Crown for CG and MOI Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads struggle to maximize discretionary mass for customizing performance and forgiveness, particularly in terms of moment of inertia (MOI) and center of gravity (CG), limiting options for golf ball flight manipulation.
Innovation Solution
A multi-component golf club head design comprising a metallic first component with a rearward sole extension and a non-metallic second component, allowing redistribution of mass to optimize CG and MOI, achieved by integrating a metallic first component with a significant rearward sole extension and a less dense non-metallic crown component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If structural mass is minimized to provide discretionary mass for customization, then discretionary mass availability improves, but structural resilience may be compromised
Solution Approach 1:
The golf club head combines a titanium alloy body with a carbon fiber reinforced polymer (CFRP) crown. The titanium alloy provides high strength-to-weight ratio and structural resilience, while the CFRP crown is significantly lighter, creating discretionary mass that can be redistributed to optimize performance characteristics such as moment of inertia and center of gravity position.
Solution Approach 2:
The club head is divided into distinct components: a titanium alloy body structure and a separate CFRP crown. This segmentation allows each material to be optimized for its specific function - the titanium body for structural integrity and the lightweight CFRP crown for mass reduction and performance customization.
2Ease of operation
If mass is redistributed to lower and back center of gravity, then control over ball flight improves, but moment of inertia may be reduced
Solution Approach 1:
Weighting elements are strategically positioned in specific locations within the club head structure, particularly in the lower and rear regions. This localized mass distribution lowers the center of gravity to improve ball flight control while the overall structural design maintains adequate moment of inertia for stability.
3Stability of the object's composition
If discretionary mass is added to maximize moment of inertia, then club head stability improves, but center of gravity position becomes harder to optimize
Solution Approach 1:
The club head incorporates adjustable weighting elements that can be repositioned within the structure. This dynamic configuration allows the center of gravity to be optimized for different performance requirements while the overall mass distribution maintains adequate moment of inertia for club head stability.

AI summary
A golf club head comprising two components, wherein the first component comprises a ball striking surface, a striking face return, a lip, and a sole portion rear extension. And wherein the second component comprises a lower density material, comprising part of the crown and part of the sole. The lip is offset toward an interior of the golf club head to define a lip surface recessed from a first component outer surface and entirely encompasses a rearward facing edge of the first component of the body. The second component comprises a second component front edge extending over the lip surface of the lip to form a lap joint between the first component and the second component. The first component sole portion rear extension comprises a heel extension length and a toe extension length. The toe extension length is greater than the heel extension length.
