Adjustable Weight Ports in Golf Club Heads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club heads do not effectively accommodate various golf swings, as the center of gravity and moment of inertia are not optimally adjustable to achieve desired launch angles and forgiveness across different swing types.
Innovation Solution
The golf club head design incorporates multiple weight portions and ports arranged in various configurations along a D-shaped loop on the bottom portion, allowing for adjustable center of gravity and moment of inertia, enabling four distinct weight configurations that optimize launch trajectories and forgiveness for different swing styles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple weight portions and ports are added to allow adjustable center of gravity and moment of inertia, then adaptability to different swing types is improved, but device complexity increases
Solution Approach 1:
The golf club head is divided into multiple weight portions (first weight portion, second weight portion, third weight portion) that can be independently adjusted within respective weight ports. This segmentation allows each weight portion to control specific aspects of center of gravity positioning, enabling fine-tuned adaptation to different swing types without requiring complete redesign of the entire weight system.
Solution Approach 2:
The weight portions are designed to be adjustable and reconfigurable within the club head structure. The center of gravity can be dynamically repositioned by redistributing the weight portions among different weight ports, allowing the club head to adapt to various swing characteristics (e.g., draw bias, fade bias, neutral) without permanent structural changes.
2Reliability
If weight portions are positioned to optimize launch angle and spin rate, then golf ball performance is improved, but manufacturing precision requirements increase
Solution Approach 1:
Multiple weight ports are provided at different locations within the club head body, allowing the weight portions to be distributed across several discrete positions rather than requiring precise continuous positioning. This segmentation of positioning options simplifies manufacturing tolerances while still enabling fine control over center of gravity location and moment of inertia properties.
Solution Approach 2:
Different weight portions are strategically placed in different weight ports to achieve specific performance characteristics. For example, positioning weight in rearward ports optimizes for higher launch angles, while forward positioning optimizes for lower spin rates. This local optimization approach allows manufacturers to target specific performance zones without requiring ultra-precise positioning across the entire club head.

AI summary
Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may have a body portion having a front portion, a rear portion, a toe portion, a heel portion, a top portion, and a bottom portion. The golf club head may include a first plurality of weight ports in the bottom portion and a second plurality of weight ports in the bottom portion. The first plurality of weight ports may form a first discrete arc along the bottom portion. The second plurality of weight ports may form a second discrete arc along the bottom portion. The first plurality of weight ports and the second plurality weight ports may be separated by a gap. Other examples and embodiments may be described and claimed.
