Adjustable Golf Club Coupling Mechanism for Loft and Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current golf club fitting methods require a large inventory of shafts and club heads to accommodate various user dimensions, leading to unnecessary storage space usage and inefficiency.
Innovation Solution
A golf coupling mechanism that adjusts club head loft angle, lie angle, and shaft length using an off-axis tilt and arcuate couplers, along with removable spacers and extenders, allowing a single shaft to fit multiple golfer dimensions without the need for a large inventory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large inventory of shafts and club heads is maintained to accommodate various user dimensions, then fitting versatility is improved, but storage space requirement increases
Solution Approach 1:
The golf club head is designed with a universal coupling mechanism that can accommodate multiple shafts with different specifications (loft angles, lie angles, lengths) through a single adjustable interface. The coupling mechanism includes adjustable components that allow one club head to serve multiple fitting purposes, replacing the need for multiple dedicated club heads and shafts.
Solution Approach 2:
The coupling mechanism incorporates dynamic adjustment capabilities, allowing the loft angle, lie angle, and shaft length to be modified after assembly. This enables the same club head-shaft combination to be adapted to different user dimensions over time, providing ongoing fitting versatility without requiring additional inventory.
2Adaptability or versatility
If multiple shafts with different specifications are kept in inventory, then accommodation of different user dimensions is improved, but inventory complexity increases
Solution Approach 1:
The coupling mechanism serves as a universal interface that can accommodate shafts with varying specifications through adjustment rather than requiring dedicated shafts for each specification. This reduces inventory complexity by allowing a smaller set of shafts to serve multiple purposes.
Solution Approach 2:
The coupling mechanism is divided into separate adjustable components (loft adjustment, lie adjustment, length extension) that can be independently modified. This segmentation allows for precise accommodation of different user dimensions without requiring complete replacement of shafts or club heads.
3Quantity of substance
If adjustable coupling mechanisms are implemented, then inventory size is reduced, but device complexity increases
Solution Approach 1:
The coupling mechanism merges multiple adjustment functions (loft, lie, length) into a single integrated assembly that attaches to the club head. This consolidation reduces the number of separate components needed compared to having separate adjustment mechanisms for each parameter, thereby reducing overall device complexity while maintaining inventory reduction benefits.

AI summary
Embodiments of golf coupling mechanisms for joining golf club heads and shafts are described herein. The golf coupling mechanism allows for adjustment of a club head loft angle, a club head lie angle, and a golf club shaft length while utilizing one club head and one shaft. In a fully extended configuration, the golf coupling mechanism includes a shaft sleeve, a removable spacer, and a removable extender, wherein a fastening assembly secures the golf coupling mechanism to the golf club head. In a contracted configuration, the golf coupling mechanism includes the shaft sleeve. The golf coupling mechanism further includes a shaft cap to soften the interaction between the shaft and the golf coupling mechanism. The golf coupling mechanism further comprises one or more arcuate coupler sets to frictionally lock the shaft relative to the golf club head.
