Golf Club Hosel Insert Coupling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf clubs with fixed coupling mechanisms between shafts and heads require numerous configurations to accommodate individual characteristics, leading to instability and lack of adjustability, making it difficult to customize equipment effectively.
Innovation Solution
A golf club coupling mechanism featuring a shaft sleeve with couplers and a receiver coupler set that restricts rotation, allowing for adjustable loft and lie angles, and a securing fastener to secure the sleeve to the hosel, enabling customizable configurations without compromising stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed coupling mechanisms are used between shafts and heads, then manufacturing and assembly are simplified, but adaptability and adjustability are reduced
Solution Approach 1:
The coupling mechanism is divided into separate components: a hosel insert with internal threads and a shaft receiver with external threads. These segments can be independently manufactured and then assembled, allowing for easier customization and adjustment of different shaft and head combinations without requiring complete redesign of the entire coupling system.
Solution Approach 2:
The coupling mechanism transitions from a fixed, permanent design to a dynamic, adjustable system. The threaded connection allows the shaft and head to be disassembled and reassembled in different configurations, enabling users to adjust loft angles and match different shafts to heads based on performance requirements.
2Adaptability or versatility
If adjustable coupling mechanisms are used to provide flexibility, then adaptability is improved, but stability and stress concentration worsen
Solution Approach 1:
The hosel insert acts as an intermediary component between the club head and the shaft receiver. This mediator distributes mechanical stresses across a larger interface area and provides a stable threaded connection that maintains structural integrity while allowing for adjustable configurations. The insert prevents direct stress concentration at the shaft-receiver interface.
Solution Approach 2:
The coupling system uses different materials for different components: the hosel insert is typically made of a durable, stress-resistant material like stainless steel or titanium, while the shaft receiver may use composite materials. This composite approach allows each component to be optimized for its specific function while maintaining overall stability and reliability.
3Adaptability or versatility
If multiple club sets are provided to accommodate individual characteristics, then adaptability is improved, but device complexity and cost increase
Solution Approach 1:
The threaded coupling system provides a universal interface that can accommodate multiple shaft and head combinations. Instead of requiring separate fixed coupling mechanisms for each configuration, a single adjustable hosel insert system can work with various shaft diameters and head types, reducing the total number of components needed while maintaining customization capability.
Solution Approach 2:
The system allows for parameter changes in loft angle and shaft compatibility through simple adjustments of the threaded connection. Users can modify the coupling parameters by rotating or repositioning the shaft receiver within the hosel insert, enabling multiple configurations without adding physical complexity or requiring additional club sets.
