Golf Club Hosel Quick Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club connection systems are cumbersome and weight-additive, making it impractical to interchange shafts and adjust weights, affecting swing speed and club performance due to the use of pins, screws, and coupling rods which are time-consuming and prone to stripping or material failure.
Innovation Solution
A quick release connection system featuring angularly disposed teeth in the hosel hole that allow easy insertion and resistant withdrawal, with a sliding release collar and optional interlock devices to prevent rotation, enabling quick and secure attachment and detachment of shafts and weights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pins, screws, or coupling rods are used to attach the shaft to the club head, then the connection is secure and reliable, but the attachment process becomes time-consuming and the club weight increases
Solution Approach 1:
The connection system is divided into separate functional elements: a hosel opening with angled teeth in the club head, a corresponding recess in the shaft, and a release collar. This segmentation allows for quick engagement and disengagement without requiring complex fastening operations.
Solution Approach 2:
The connection system transitions from a static fixed connection to a dynamic reversible connection. The release collar can be moved along the shaft to engage or disengage the teeth, providing quick release functionality that maintains security during play but allows rapid adjustment when needed.
2Reliability
If pins, screws, or coupling rods are used to attach the shaft to the club head, then the connection is secure, but the club performance is negatively affected due to increased weight and reduced swing speed
Solution Approach 1:
The heavy traditional fastening components (pins, screws, coupling rods) are completely removed from the connection system. Instead, a lightweight tooth-and-recess mechanism with a simple release collar is used, significantly reducing the weight added by the connection system while maintaining reliability.
3Reliability
If traditional connection methods are used, then the connection is secure, but the materials are subject to stripping and failure under excessive forces
Solution Approach 1:
The connection system uses locally optimized features: angled teeth with specific geometric properties in the hosel opening, a corresponding recess shape in the shaft, and a release collar with appropriate thickness and material. These local quality enhancements provide strength where needed while maintaining overall lightweight design.

AI summary
The present invention is directed at a quick release connection system to facilitate customization of golf clubs. It can be used to interchange shafts, removable weights, or soleplates quickly and easily. Teeth are disposed on the inside of a frame so that a shaft may be inserted with minimal resistance, but cannot be removed without specific steps which may require the use of a simple tool. Strengthening and interlock devices are provided to ensure performance quality akin to traditional golf clubs.
