Golf Club Head Weighted Sole for Center of Gravity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf club heads lack effective internal weighting solutions that accurately position the center of gravity near the face and sole, affecting control and performance during play.
Innovation Solution
The design incorporates a weight bar within the rear cavity of the golf club head, bridging the sole and connected to the heel and toe sides, using multiple materials and configurations to optimize weight distribution, including a weight lip and perimeter weighting element, which does not contact the face component, allowing for adjustable center of gravity placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional weighting methods are used in golf club heads, then manufacturing is simpler, but the center of gravity cannot be positioned close to the face and sole, reducing control
Solution Approach 1:
The weighting structure is segmented into multiple components: a weight bar with first and second ends, a weight lip, and a perimeter weighting element. These segmented elements allow independent positioning and adjustment of mass distribution to achieve precise center of gravity placement near the face and sole.
Solution Approach 2:
The weight bar bridges across the sole dimension, extending from the heel side to the toe side, while the weight lip positions mass vertically near the sole. This multi-dimensional weight distribution enables the center of gravity to be positioned close to both the face (front-back dimension) and sole (vertical dimension) simultaneously.
2Strength
If the weight bar contacts the face component, then structural support is improved, but the center of gravity position becomes less adjustable and face flexibility is reduced
Solution Approach 1:
The weight bar is extracted from direct contact with the face component, positioning it within the rear cavity instead. This separation allows the face component to maintain its flexibility and independent function while the weight bar provides structural support through the body and sole without constraining the face.
Solution Approach 2:
The body and sole act as intermediary structures between the weight bar and the face component. The weight bar connects to the heel side and toe side of the sole, transmitting structural support through these intermediaries rather than directly to the face, thereby maintaining both strength and adjustability.
3Ease of manufacture
If uniform material distribution is used, then manufacturing is easier, but mass distribution cannot be optimized for performance characteristics
Solution Approach 1:
Different regions of the golf club head are assigned different material densities and mass concentrations. The weight bar, weight lip, and perimeter weighting element create localized high-density regions that optimize mass distribution for performance, while the rest of the body maintains simpler construction for ease of manufacture.
Solution Approach 2:
The golf club head employs composite construction with multiple materials of different densities strategically positioned. High-density weighting elements (weight bar, weight lip, perimeter weighting) are combined with the base body material to create optimized mass distribution, achieving both manufacturing feasibility and performance precision.

AI summary
A golf club head having a center of gravity located at a point close to the face and the sole is disclosed herein. In particular, the golf club head comprises a hollow body including a weight lip and face component, and the weight lip extends from the sole inside the body towards the face component without making contact with the face component. The golf club head is preferably a wood-type or hybrid-type golf club head. In other embodiments, the golf club head, which may be an iron-type golf club head, comprises a weight bar disposed within the hollow body proximate the face component, and the weight bar bridges at least a portion of the sole. The weight bar may be movable within the hollow body to allow for center of gravity adjustment.
