Golf Club Hosel Slot Coupler Alignment Mechanism

Solution Overview

Problem

Current golf club attachment mechanisms fail to securely align and maintain the orientation of golf club shafts and heads, leading to inconsistent performance and potential disengagement during use.

Innovation Solution

A golf club attachment mechanism comprising a hosel adapter with a first slot coupler and a shaft adapter with a complementary second slot coupler, coupled by a cap that restricts rotational movement, ensuring a predetermined desired orientation between the shaft and head.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional golf club attachment mechanism is used, then the structure is simple, but the alignment and orientation of the shaft relative to the head cannot be securely maintained

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The attachment mechanism is divided into separate functional components: a hosel adapter that interfaces with the club head, a shaft adapter that interfaces with the shaft, and a cap that secures the connection. This segmentation allows each component to perform its specific function while maintaining overall alignment reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The slot coupler features an asymmetric geometry with a slot in the hosel adapter and a complementary protrusion in the shaft adapter. This asymmetric design prevents rotational movement of the shaft relative to the head, ensuring consistent orientation while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #4Asymmetry

2Manufacturing precision

If the attachment mechanism allows free rotation, then the device complexity is reduced, but the performance consistency deteriorates

Engineering Contradiction:
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The slot coupler employs asymmetric geometry where the slot in the hosel adapter receives a complementary protrusion from the shaft adapter. This asymmetric interface mechanically prevents rotational movement, ensuring precise and consistent orientation without requiring complex active control mechanisms.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The slot coupler acts as an intermediary mechanical element between the hosel adapter and shaft adapter. It mediates the connection by providing a positive mechanical stop that maintains the predetermined orientation of the shaft relative to the head, achieving manufacturing precision through a relatively simple mediating structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

In one embodiment, a golf club attachment mechanism comprises a hosel adapter with a first slot coupler across a top portion of the hosel adapter, and a shaft adapter with a second slot coupler across a bottom portion of the shaft adapter. The second slot coupler of the shaft adapter is complementary to the first slot coupler of the hosel adapter. The first slot coupler and the second slot coupler couple together to restrict a rotational movement of the hosel adapter relative to the shaft adapter. Other embodiments are disclosed herein.
