Golf Club Hosel Segmentation for Adjustable Shaft Deflectability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf clubs that vary shaft hardness without replacing the shaft face complications in operation and cause discomfort due to changes in neck length and club length, leading to reduced user comfort.
Innovation Solution
A golf club design featuring a securing member and an insert member that can be detachably attached to the hosel, allowing for adjustable hosel length without altering the shaft, maintaining constant club length and preventing discomfort by varying the shaft's deflectability without changing the neck length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the shaft is replaced to vary flexure, then the shaft hardness can be changed, but the cost increases
Solution Approach 1:
The hosel is segmented into a head body portion and an extension member portion that can be detachably connected. This allows the effective hosel length to be varied by attaching or detaching the extension member, thereby changing shaft deflectability without replacing the entire shaft assembly, reducing cost while maintaining adaptability
Solution Approach 2:
The hosel length is made dynamically adjustable through the detachable extension member. Users can switch between different hosel lengths (with or without extension member) to vary shaft deflectability according to playing conditions, achieving adaptability without permanent modification or costly shaft replacement
2Adaptability or versatility
If the hosel length is extended by fitting a cylindrical extension member to vary shaft deflectability, then the shaft hardness effect is achieved, but the operation becomes complicated
Solution Approach 1:
The hosel is divided into separable components (head body and extension member) that can be independently handled. The extension member can be attached or detached without removing the shaft from the club head, simplifying the operation while achieving deflectability variation
Solution Approach 2:
The extension member is extracted as a separate optional component that can be added or removed independently. This allows users to adjust shaft deflectability by simply attaching or detaching the extension member to the hosel aperture, avoiding complicated multi-step procedures
3Adaptability or versatility
If the hosel length is extended by fitting an extension member, then the shaft deflectability is varied, but the neck length increases causing user discomfort
Solution Approach 1:
Instead of extending the hosel in the axial direction (increasing neck length), the extension member is designed to extend in a radial direction from the hosel aperture. This dimensional change allows effective hosel length extension for shaft deflectability adjustment without increasing the axial neck length, maintaining user comfort
Solution Approach 2:
The extension member is designed to fit within or alongside the existing hosel structure without protruding axially. By nesting the extension functionality within the radial space of the hosel aperture, the effective length is extended while maintaining the external dimensions and user comfort

AI summary
A golf club includes a shaft, a golf club head including a hosel having an aperture to which the shaft being secured, a securing member configured in a cylindrical shape to cover the shaft, the securing member including a first securing portion detachably fitted to the aperture of the hosel, and an insert member configured in a cylindrical shape to cover the shaft, the insert member including a second securing portion being detachably attachable to the aperture of the hosel and a third securing portion being detachably attachable to the first securing portion of the securing member. The golf club is capable of adopting a first mode of securing the first securing portion to the hosel, and a second mode of securing the insert member to the hosel and securing the first securing portion to the third securing portion of the insert member.
