Adjustable Hosel Golf Club Head with Interchangeable Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf club designs lack a fully integrated adjustable system that cooperatively adjusts loft, lie, bounce, and spin characteristics, often resulting in suboptimal performance due to isolated improvements in hosel adjustability, surface texture, and center of gravity without comprehensive interaction.
Innovation Solution
A fully adjustable golf club head with interchangeable components, including an adjustable hosel, interchangeable rear flange for bounce angle adjustment, and a flight weight bar to affect the center of gravity, along with a novel milled surface roughness pattern for optimal spin control, allowing for comprehensive adjustments in loft, lie, and spin orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an adjustable hosel is implemented to modify loft and lie angles, then some performance characteristics are improved, but other angles change that may not be desired
Solution Approach 1:
The adjustable hosel is divided into separate functional segments: an outer hosel portion that interfaces with the club head and a inner hosel portion that interfaces with the shaft. This segmentation allows independent adjustment of loft and lie angles by rotating the outer hosel relative to the inner hosel, enabling precise control without unintended angle changes.
Solution Approach 2:
A shaft sleeve acts as an intermediary component between the shaft and the adjustable hosel. The shaft sleeve contains a shaft receiving bore with a specific orientation that mediates the transmission of angles, allowing the hosel to adjust loft and lie independently while maintaining the desired shaft orientation and preventing unintended angle changes.
2Adaptability or versatility
If surface roughness is increased to control ball spin, then spin control is improved, but USGA regulatory limits are exceeded
Solution Approach 1:
The striking face is equipped with localized spin control elements such as grooves, dimples, or textured regions at specific locations rather than uniform surface roughness across the entire face. This allows enhanced spin control in critical impact zones while keeping the overall surface roughness within USGA regulatory limits, achieving selective spin manipulation without regulatory violation.
3Adaptability or versatility
If multiple adjustability features are added to the golf club, then adaptability is improved, but device complexity increases
Solution Approach 1:
The adjustable hosel is designed as a multi-functional component that simultaneously provides loft adjustment, lie angle adjustment, and shaft orientation control through a single integrated mechanism. This eliminates the need for separate adjustment devices for each parameter, reducing overall device complexity while maintaining multiple adjustability features.
Solution Approach 2:
Multiple adjustment functions are merged into a single adjustable hosel assembly that can perform loft adjustment, lie angle adjustment, and shaft positioning through coordinated rotation of its components. This consolidation reduces the number of separate parts and simplifies the overall club construction while providing comprehensive adjustability.

AI summary
A modular golf club head system provides a hosel adapter that can be attached to the club head at different rotational positions to selectively change the loft or lie angle of the club head. The club head defines a hosel ball socket, and a locator pin extends from the socket. The hosel adapter has a shaft end configured for connecting to a golf club shaft, and a distal end including a hosel ball inserted into the hosel ball socket. The hosel ball defines at least one first locator pin recess and at least one second locator pin recess. The locator pin recesses formed in said hosel ball at differing angles, wherein insertion of the locator pin into the first locator pin recess defines at least one of the loft and lie angle of the club head, and insertion of the locator pin into the second locator pin recess defines a different loft or lie angle of the club head.
