Reverse Taper Golf Putter Grip Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf putter grips do not adequately promote consistent hand placement, lower hand pressure, and a controlled release of the putter face through impact.
Innovation Solution
The development of golf putter grips featuring unique geometric profiles with a reverse taper design, which increases in size from the cap end to the mouth end, providing a gradual grip size transition and maintaining hand articulation and pressure throughout the putting stroke.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional tapered grip design is used, then the grip size decreases from cap to mouth, but this does not promote consistent hand placement or lower hand pressure
Solution Approach 1:
The patent applies inversion by reversing the conventional grip taper direction. Instead of the grip decreasing in size from cap to mouth (traditional design), the grip increases in size from cap to mouth. This inverted geometry promotes consistent hand placement and reduces hand pressure by maintaining better hand articulation throughout the putting stroke.
2Ease of operation
If a straight profile grip is used, then the diameter remains constant, but this does not provide controlled release of the putter face through impact
Solution Approach 1:
The patent applies local quality by creating different geometric characteristics at different portions of the grip. The grip features a gradual size increase from cap to mouth, with specific emphasis on the lower portion near the mouth providing enhanced control for face release. This localized geometric variation optimizes different functional requirements along the grip length.
3Ease of operation
If complex grip geometries are introduced to improve hand control, then hand placement consistency improves, but grip design complexity increases
Solution Approach 1:
The patent applies parameter changes by modifying the geometric parameters of the grip, specifically the taper direction and rate. Rather than introducing complex multi-dimensional geometries, the invention achieves improved hand placement consistency through a controlled change in the grip's dimensional parameters along its length, maintaining relative design simplicity.

AI summary
A golf grip defines a body having a length extending between an upper cap end and a lower mouth end, the body including a bore for receiving the shaft of the golf club. The body includes a tapered portion that extends along at least about 75 percent of the length of the body between an upper location and a lower location, the bore extending longitudinally through the tapered portion. The tapered portion includes a front side, a back side, a left side, and a right side, the tapered portion defining a width between the left and right sides and a depth between the front and back sides. The tapered portion has a reverse taper between the left and right sides that expands the width of the tapered portion as the tapered portion extends from the upper location to the lower location. The tapered portion has a second reverse taper defined between the front and back sides that expands the depth of the tapered portion as the tapered portion extends from the upper location to the lower location.
