Golf Club Grip Angle Transition for Consistent Hand Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club grips fail to provide adequate control and consistency in maintaining the desired orientation and swing path, making it difficult for players to achieve consistent shots.
Innovation Solution
A golf club grip design featuring a main portion and a control portion with a distinct angle transition, where the control portion is angled relative to the central axis, allowing the thumb and forefinger to engage, enhancing grip control and providing tactile reference points for consistent hand positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional uniform grip design is used, then the grip structure is simple and easy to manufacture, but the control and consistency of the golf club during swing is insufficient
Solution Approach 1:
The grip is divided into three distinct segments: a main portion, a control portion with a distinct angle transition, and a tapered portion. This segmentation allows each section to serve a specific function - the main portion provides general hand contact, the control portion with its angled surface and tactile reference points enables precise thumb and forefinger positioning for improved control, and the tapered portion provides a smooth transition. The segmentation resolves the contradiction by introducing structural complexity only where needed for control enhancement.
Solution Approach 2:
The control portion features a localized angled surface with a specific angle range (10-20 degrees) relative to the longitudinal axis, creating tactile reference points that differ from the uniform cylindrical shape of other grip sections. This local quality change concentrates the control-enhancing features exactly where the thumb and forefinger make contact, providing improved grip consistency without requiring the entire grip structure to be complex.
2Measurement precision
If the control portion has a larger angle relative to the central axis, then the tactile reference points for hand positioning are more distinct, but the grip thickness varies more significantly along the axial length
Solution Approach 1:
The control portion employs a dynamic thickness profile that transitions from a maximum thickness at the upper end (adjacent to the main portion) to a minimum thickness at the lower end. This dynamic variation in thickness, with specific ranges (0.25-0.33 inches at the upper end, 0.1-0.2 inches at the lower end), accommodates the angled surface geometry while maintaining structural integrity and providing the desired tactile reference points for improved hand positioning accuracy.

AI summary
A grip for a golf club includes an outer surface adapted to be grasped by a user, an inner surface the defines a cavity adapted to receive part of a shaft of a golf club, a main portion having a first end adapted to be received adjacent to a top end of the shaft and a second end spaced from the first end, the main portion defines part of the outer surface, the inner surface, and a control portion. The control portion extends from the main portion to a bottom end of the grip, and defines part of the inner and outer surfaces. At the outer surface, the control portion is arranged at a greater angle relative to a central axis of the cavity than the main portion, and the control portion is arranged to be contacted by a thumb and forefinger of a hand holding the grip.
