Modular Putter Head Assembly with Two-Part Hosel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf putters are either monolithic, requiring replacement of the entire club when any component is damaged, and configurable putters often lack sufficient options or have complex assembly processes, leading to resource inefficiencies and undesirable aesthetics.
Innovation Solution
A golf putter head assembly with a two-part hosel detachably mounted to the putter head using a single removable fastener, allowing for interchangeable components such as putter heads, intermediate connectors, and shaft connectors to customize lie angle, head balance, and offset distance, enabling various configurations without complex assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If monolithic putters are used, then structural simplicity and manufacturing ease are improved, but adaptability and resource efficiency deteriorate
Solution Approach 1:
The putter is divided into separate modular components: hosel, shaft connector, intermediate connector, and putter head. Each component can be independently manufactured, assembled, and replaced, enabling both manufacturing efficiency and player customization without requiring multiple complete putters in inventory.
2Adaptability or versatility
If configurable putters with many components are used, then adaptability is improved, but device complexity and assembly difficulty worsen
Solution Approach 1:
Multiple functional elements (shaft connector, intermediate connector, alignment features, and fastening mechanisms) are merged into an integrated hosel assembly that attaches to the putter head through a single through-bore. This consolidation provides numerous configuration options while maintaining simple assembly requiring only one fastener.
3Adaptability or versatility
If configurable putters with many components are used, then adaptability is improved, but aesthetics worsen
Solution Approach 1:
The shaft connector and intermediate connector are nested within the hosel structure, with alignment features and fastening mechanisms concealed within the through-bore. This nesting allows multiple configurable components to be integrated in a compact, aesthetically pleasing manner without visible complexity.
4Device complexity
If monolithic putters are used, then device complexity is reduced, but loss of substance and resource efficiency worsen
Solution Approach 1:
The modular component design enables selective replacement of only the damaged or worn component (hosel, shaft connector, or putter head) rather than discarding the entire putter. This extends the lifecycle of each component and reduces material waste and resource consumption.

AI summary
A golf putter head assembly includes a putter head and a two-part hosel detachably mounted to the putter head by a single removable fastener. The two-part hosel includes a lower intermediate connector extending upwardly from the putter head, and an upper shaft connector extending upwardly from the intermediate connector. The fastener extends through a crown-to-sole through-bore formed in the putter head, through a longitudinal through-bore formed in the intermediate connector, and into a blind bore formed in a lower member of the shaft connector. An upper member of the shaft connector is mountable to a putter shaft. The upper member is angled relative to the lower member to define a shaft-head lie angle, and is offset from the lower member to define a shaft-head offset distance. The intermediate connector has a selected length that establishes a shaft-head balance characteristic. A kit and a method are also disclosed.
