Composite Golf Club Head Weight Ports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf club heads with increased volume and moments of inertia suffer from deleterious effects such as increased side-spin and reduced backspin due to a center of gravity positioned rearward from the front face, limiting face size and causing undesirable ball flight trajectories, and require new club heads for weight adjustments.
Innovation Solution
A golf club head with integrally formed weight ports in a composite sole or body patch that house removable weights, allowing for external adjustment of swing weight and moment of inertia without manufacturing a new club head, using composite materials like SMC with ribs for support and a metal face component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the center of gravity is positioned further rearward from the front face to increase moments of inertia, then forgiveness for off-center hits is improved, but side-spin increases and ball flight robustness deteriorates
Solution Approach 1:
The patent applies local quality by positioning weights specifically in the toe section rather than uniformly distributing mass throughout the club head. This localized weight placement increases the moment of inertia about the vertical axis while minimizing the rearward shift of the center of gravity, thereby reducing excessive side-spin on off-center hits while maintaining forgiveness.
2Area of moving object
If the face size is increased to maximize hitting area, then the club head volume is improved, but the center of gravity shifts rearward causing increased gear effect
Solution Approach 1:
The patent uses local quality by concentrating mass in the toe section through weight ports rather than uniformly distributing weight throughout the enlarged club head volume. This allows the face area to be maximized while the localized toe weights counterbalance the gear effect caused by the enlarged volume and prevent excessive rearward center of gravity shift.
3Adaptability or versatility
If weights are adjusted to modify swing weight and center of gravity, then adaptability is improved, but manufacturing complexity increases requiring new club heads
Solution Approach 1:
The patent applies segmentation by dividing the club head into modular components: the main club head body and separate removable weight inserts. The weight ports are pre-formed in the club head, allowing weights to be independently added, removed, or replaced without requiring new club head manufacturing. This enables weight adjustment while maintaining manufacturing efficiency.
Solution Approach 2:
The patent uses the nested doll principle by placing removable weight inserts inside pre-formed weight ports within the club head structure. The weights are nested within the club head body, allowing easy insertion and removal through the weight ports without affecting the main club head structure or requiring new manufacturing.

AI summary
A golf club head having a face component, a crown, and a composite sole or a composite body patch with one or more weight ports for receiving one or more weight inserts is disclosed herein. At least part of each of the weight ports is integrally formed in the composite sole or composite body patch, and each of the weight ports include a weight receiving region for receiving a weight and a screw receiving region for receiving a screw that secures the weight in the weight port.
