Solution Overview

Problem

Amateur golfers often experience early club release during the downswing due to an excessively tight grip, which limits lag angle and club head speed, resulting in shorter drive distances.

Innovation Solution

A golf club attachment with a C-shaped cuff and adjustable strap that reduces wrist tension, providing a secure grip without the need for excessive force, allowing for a more natural lag angle and increased club head speed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a golfer uses an excessively tight grip to prevent club twisting, then grip security is improved, but wrist tension increases causing early release

Engineering Contradiction:

Improvegrip securityVSAvoidwrist tension

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The attachment device acts as an intermediary between the golfer's hand and the club grip. It provides a secondary retention mechanism that shares the load of securing the club, allowing the golfer to use a lighter primary grip force while maintaining overall grip security through the combined action of the attachment and the hand grip.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If a golfer uses excessive grip force to maintain control, then club control is improved, but lag angle is reduced leading to early release

Engineering Contradiction:

Improveclub controlVSAvoidlag angle

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

The attachment serves as a mediator that provides club retention through mechanical engagement rather than grip force. This allows the golfer's hand and wrist to remain more relaxed, preserving the natural lag angle geometry while still maintaining control through the attachment's mechanical retention mechanism.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Speed

If a golfer reduces grip force to maintain lag angle, then club head speed is improved, but grip security is reduced

Engineering Contradiction:

Improveclub head speedVSAvoidgrip security

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The attachment device functions as a security intermediary that compensates for reduced grip force. It provides mechanical retention through friction engagement and geometric interlocking, allowing the golfer to use lighter grip force to maintain wrist flexibility and club head speed while the attachment ensures the club remains securely retained.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The attachment changes the retention parameter from relying solely on grip force to utilizing mechanical engagement parameters including friction coefficient, engagement geometry, and normal force distributed through the attachment structure. This parameter shift allows lighter grip forces while maintaining security.

AI summary

A method and device for improving golf ball drive speed and accuracy and decreasing wrist tension in the performance of swinging a golf club, by decreasing the burden of grip force to afford retention of the grip of a golf club during the swing, and by subsequently reducing detrimental and compounding effects resulting from other, prior methods in the art that are used to control swing motion.
