Golf Grip Asperity Scales for Tactile Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf clubs face issues with inconsistent grip positioning and visual quality, as existing technologies require frequent adjustments for directionality and driving distance, and markers on longer grip parts are prone to disappearance due to sweat and friction, affecting the accuracy of the golf swing.
Innovation Solution
A grip structure featuring positioning scales and angle adjustment scales formed with asperity on the grip part, allowing for tactile confirmation of grip position and orientation, preventing marker disappearance and enhancing visual appeal by integrating scales within surface grain regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If markers are established on the grip part to indicate grip position, then grip positioning accuracy is improved, but the markers easily disappear due to sweat and friction
Solution Approach 1:
The patent replaces visual markers (chromatic lines) with tactile markers (asperities) on the grip part. The asperities provide grip position information through tactile sensation rather than visual detection, eliminating the problem of marker disappearance due to sweat and friction while maintaining grip positioning accuracy.
2Adaptability or versatility
If the grip part is made longer to allow grip position adjustment, then adaptability is improved, but visual quality and aesthetic appearance deteriorate
Solution Approach 1:
The patent replaces visual indication methods with tactile indication methods. The asperities embedded in the grip part provide clear tactile feedback for grip position without requiring long grip parts or visible markers, thus maintaining aesthetic appearance while enabling grip position adjustment and improving adaptability.
3Loss of information
If visual markers are used to indicate grip position, then grip position can be identified, but the user cannot recognize grip position changes during swing preparation
Solution Approach 1:
The patent replaces visual markers with tactile markers (asperities) that provide continuous tactile feedback during grip adjustment and swing preparation. The user can feel the asperities through hand contact, enabling real-time recognition of grip position changes without relying on visual markers that become invisible during the swing preparation phase.

AI summary
[Subject] The objective is to provide a grip structure that enables a user to certainly grip a grip part at a predetermined position; concurrently, that excels in visual quality and is aesthetically pleasing.[Resolution Means] Scales 50 are established at predetermined intervals in the axial direction of a grip part 16, for example, on a toe side peripheral part 30 and a heel side peripheral part out of a circumferential surface 28 of the grip part 16, and particularly on the toe side peripheral part 30, the scales 50 are formed with asperity expanding toward a circumferential direction of the grip part 16. This scale 50 functions as a positioning scale and/or an angle adjustment scale. Further, angle adjustment scales 60, 62 and 64 may be established at the lower portion of the grip part 16.
