Putter Head Weight Ports and Hosel Options for CG Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club heads struggle to optimize mass properties and alignment for improved performance, particularly in putting, due to limitations in adjusting center of gravity and shaft axis alignment.
Innovation Solution
The golf club heads incorporate a hollow design with interchangeable weight ports and hosel systems, allowing for adjustable mass distribution and alignment aids, such as alignment aids and interchangeable hosel types, to optimize center of gravity and shaft axis alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If golf club heads use fixed mass properties and alignment, then manufacturing is simpler, but adaptability to individual putting styles is reduced
Solution Approach 1:
The golf club head is divided into separate functional components: a hosel assembly with interchangeable hosel types (face-balanced, toe-balanced, neutral) and a club head body with interchangeable weight ports. This segmentation allows users to mix and match components to achieve desired mass properties and alignment characteristics without redesigning the entire club head.
Solution Approach 2:
The club head incorporates adjustable and interchangeable elements rather than fixed configurations. Users can dynamically adjust mass distribution through interchangeable weight ports and hosel types, transforming a static club head into a dynamic system that adapts to different putting styles and performance requirements.
2Ease of operation
If golf club heads use standardized alignment aids, then manufacturing precision is easier to achieve, but ease of operation for different putting styles is reduced
Solution Approach 1:
The alignment aid system transitions from a fixed, static configuration to a dynamic, adjustable system. Interchangeable hosel types (face-balanced, toe-balanced, neutral) and adjustable weight ports enable users to modify alignment characteristics after purchase, making the club head adaptable to different putting styles without requiring multiple precision-manufactured fixed variants.
Solution Approach 2:
The alignment function is separated into modular components: the hosel assembly with different balance types and the club head body with weight ports. This allows alignment characteristics to be adjusted independently of the club head shell, simplifying manufacturing while maintaining operational flexibility.
3Adaptability or versatility
If golf club heads use fixed center of gravity positioning, then structural stability is improved, but adaptability for performance optimization is reduced
Solution Approach 1:
The center of gravity adjustment system is segmented into modular weight ports and interchangeable weight components. This allows the center of gravity to be adjusted in discrete, controlled increments while maintaining overall structural integrity. The weight ports are integrated into the club head shell in a way that preserves structural stability while enabling mass property optimization.
Solution Approach 2:
The center of gravity transitions from a fixed position to an adjustable position through interchangeable weight ports and hosel types. This dynamic adjustment capability allows users to optimize mass distribution for different putting styles while the overall club head structure remains stable and rigid.

AI summary
Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club includes a shaft with forward shaft lean coupled to a golf club head. The golf club head includes a heel portion having a first shaft marker and a second shaft marker. The first shaft marker and the second shaft marker are spaced apart from one another such that when the golf club head is at an address position to strike a golf ball, the shaft appears to be located between the first shaft marker and the second shaft marker from a vantage point of an individual positioned over the golf club head at address. Other examples and embodiments may be described and claimed.
