Custom Golf Grip Indicia for Consistent Hand Positioning

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing golfing technologies fail to provide consistent grip alignment for golfers, especially those who do not use a traditional 'textbook' grip, and often require specialized gloves or training aids that violate golf competition rules or reduce feel for the clubface.

Innovation Solution

A customizable method and apparatus allowing golfers to apply their own grip alignment indicia directly on any commercially available glove and ungloved hand using 3D-printed tools, ensuring alignment with the golf club shaft for precise grip adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If specialized golf gloves or training aids with grip alignment features are used, then grip consistency is improved, but the solution violates golf competition rules or reduces feel for the clubface

Engineering Contradiction:

Improvegrip consistencyVSAvoidcompatibility with competition rules

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent extracts the grip alignment feature from the glove itself and places it on the club shaft. By removing the indicia from the glove and transferring it to the shaft, the solution eliminates the need for specialized gloves while maintaining grip alignment guidance, thus complying with competition rules that prohibit unfair advantages in hand positioning.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces the club shaft as an intermediary carrier for the grip alignment indicia. Instead of placing indicia directly on the glove (which would violate rules), the indicia are placed on the shaft, which serves as a neutral intermediary that guides grip placement without providing an unfair advantage, since the shaft is already part of the standard equipment.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If preprinted indicia indicating a proper 'textbook' grip are used, then grip alignment is improved, but it does not accommodate individual grip preferences or anatomical variations

Engineering Contradiction:

Improvegrip alignment precisionVSAvoidaccommodation of individual preferences

Core Design Contradiction:

Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent makes the indicia dynamic and adjustable rather than fixed. Golfers can move, resize, reposition, or remove the indicia on the shaft according to their individual grip preferences and anatomical variations. This dynamic approach allows the same indicia system to adapt to different grip styles (neutral, strong, weak) and hand sizes while maintaining alignment precision.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent enables preliminary customization where golfers can pre-position and secure the indicia on the shaft before playing. This allows each golfer to set up the indicia in their preferred location and orientation, ensuring the alignment guidance is tailored to their specific grip style before the actual play begins.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If indicia are placed on the club shaft, then grip alignment is improved and competition rules are followed, but the indicia may be obscured by the golfer's hand or club movement

Engineering Contradiction:

Improvegrip alignment guidanceVSAvoidobscuration by hand or club movement

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent positions the indicia in multiple spatial dimensions on the shaft, including the upper shaft near the grip and extending down the shaft. This multi-dimensional placement ensures that at least one indicium remains visible and accessible to the golfer's eye during the setup process, avoiding complete obscuration by the hand or club movement.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent employs high-contrast color combinations for the indicia, such as fluorescent or brightly colored markings on the shaft. This color enhancement ensures the indicia remain visible and distinct even when partially obscured by the golfer's hand or club, maintaining grip alignment guidance throughout the setup process.

Inventive Principle:

Principle #32Color changes

AI summary

An apparatus and process wherein a golfer can apply visual aids (Indicia) to any commercially available golf glove as well as to the golfer's ungloved hand that can be used to improve consistency in the manner of gripping a golf club from shot-to-shot and from round-to-round. The position and alignment of the Indicia on the golf glove are customized to match the golfer's preferred or accustomed manner of placing their hands on the grip of a golf club. By applying Indicia directly to the golfer's ungloved hand as well, the positioning of that hand can also be evaluated without impacting the golfer's feel for the clubface and golf swing.
