Separately Cast Titanium Hosel for Golf Club Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional machining or forming of hosels in golf club manufacturing limits the geometry and strength of multi-piece drivers, leading to material availability and strength issues, particularly with adjustable designs, which often result in cracking and failure.
Innovation Solution
A golf club head with a separately cast metal hosel from strong materials like titanium alloys, allowing for complex geometry and adjustability without additional material cost or tool wear, and is permanently affixed to other components using welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If machining or tooling is used to form hosels in multi-piece golf clubs, then the manufacturing process is controllable and tool life is good, but the material strength is insufficient leading to cracking and failure
Solution Approach 1:
The patent changes the manufacturing parameter from machining to casting, which enables the use of stronger materials (titanium alloys like 6-4 titanium) that can withstand the stresses of adjustable hosel designs without cracking or failing, while maintaining production efficiency
Solution Approach 2:
The patent uses titanium alloy materials in the cast hosel that combine strength and durability properties, creating a composite construction that integrates the hosel with the club head components through welding while maintaining structural integrity
2Strength
If stronger material is used to machine or tool adjustable hosels, then the hosel strength increases, but tool wear increases and machining time increases
Solution Approach 1:
The patent replaces the mechanical machining process with a casting process, eliminating tool wear and long machining times while producing hosels from strong titanium alloy materials that meet strength requirements without compromising production efficiency
3Productivity
If machined or tooled hosels are used in multi-piece drivers, then the manufacturing process is efficient, but the geometry and complexity of the hosel are limited
Solution Approach 1:
The patent changes the manufacturing method from machining to casting, which removes geometric constraints and enables complex adjustable hosel designs with multiple features (teeth, pins, holes, ridges) while maintaining production efficiency through the casting process
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution results in a more durable and less brittle hosel that can withstand a higher number of hits, improving the structural soundness and production efficiency of golf club heads.
Implementation Method 1
The hosel is cast from a metal material
Implementation Method 2
The hosel is permanently affixed to at least one of the crown, sole, and face component after casting is complete

AI summary
The present invention is directed to a multi-piece golf club head having a metal hosel with adjustability features that is cast separately from a face component, sole, and crown, and then is permanently affixed to those other parts after casting is complete. The face component, sole, and crown may be composed of any suitable materials, but preferably each of the face component, the sole, and the crown are stamped from a metal material and are welded to the hosel.
