Golf Club Hosel Adapter Segmentation for Angle Adjustability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club designs limit the degree of freedom in adapter design due to the requirement that the shaft must be fixed to prevent axial rotation, restricting the shapes and configurations of adapters.
Innovation Solution
A golf club design that includes a hosel portion with specific coupling features and adapters allowing for multiple rotation positions, enabling the shaft to be fixed in an inclined manner without requiring the second adapter to be incapable of axial rotation, thus increasing design flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shaft is fixed to prevent axial rotation using traditional adapter designs, then the shaft maintains axial stability, but the degree of freedom in adapter design is limited and adapter shapes are restricted
Solution Approach 1:
The adapter system is divided into multiple independent adapters (first adapter, second adapter, third adapter) that can be separately designed and configured. Each adapter has its own coupling portions and can be independently adjusted to different rotation positions, allowing complex overall functionality to be achieved through simple individual components.
Solution Approach 2:
The adapters are nested within the hosel portion, with each subsequent adapter fitting into the previous one. The first adapter is accommodated in the hosel portion, the second adapter is accommodated in the first adapter, and the third adapter is accommodated in the second adapter, creating a compact nested structure that maximizes space utilization while maintaining design flexibility.
2Reliability
If traditional adapter designs are used to fix the shaft, then axial rotation is prevented, but the complexity of the adapter system increases due to shape constraints
Solution Approach 1:
The fixation function is segmented across multiple adapters rather than requiring a single complex adapter. Each adapter has a relatively simple structure with coupling portions that can be independently configured, reducing the complexity of individual components while achieving reliable shaft fixation through their combined action.
Solution Approach 2:
Each adapter serves multiple functions: providing structural support, enabling rotation adjustment, preventing axial rotation through coupling portions, and allowing detachable attachment. This multi-functionality reduces the need for additional specialized components, simplifying the overall system.
3Adaptability or versatility
If multiple rotation positions are enabled for adapter adjustment, then lie angle, loft angle, and face angle adjustability is improved, but the structural complexity of the coupling system increases
Solution Approach 1:
The angle adjustment capability is segmented across three independent adapters, each contributing to the overall adjustability. The first adapter provides rotation positions relative to the hosel portion, the second adapter provides rotation positions relative to the first adapter, and the third adapter provides rotation positions relative to the second adapter, allowing fine-grained control over lie angle, loft angle, and face angle.
Solution Approach 2:
The nested arrangement of adapters within the hosel portion allows multiple rotation mechanisms to be compactly integrated. Each adapter can rotate independently within its accommodating space, enabling multiple angle adjustments without requiring a large or complex external structure.

AI summary
In a golf club according to one aspect of the present invention, a first coupling portion of a first adapter, to which the shaft is fixed, and a hosel first coupling portion of the golf club head are coupled so as to be incapable of axial rotation, and thus the shaft is attached to the golf club head so as to not be capable of axial rotation. Accordingly, the second adapter coupled to the first adapter at least does not need to be configured so as to be incapable of axial rotation, thus making it possible to increase the degree of freedom in adapter design.
