Solution Overview

Problem

Existing golf club grips with reminder ribs often lead to inconsistencies in rib height due to variations in shaft size and tape layers, making it difficult for players to consistently feel the reminder, which affects hand alignment and shot consistency.

Innovation Solution

A golf club grip design with protruding reminder ribs that extend from the outer surface of the hollow main body, allowing consistent feel regardless of shaft size or tape layers, and conforming to PGA and USGA regulations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If reminder ribs are inserted onto a shaft of a golf club, then the grip can provide hand alignment assistance, but the rib height becomes inconsistent due to variations in shaft size and tape layers

Engineering Contradiction:
Improvehand alignmentVSAvoidrib height consistency
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The protruding feature is pre-formed as an integral part of the grip core during manufacturing, before the grip is installed on the shaft. This preliminary formation ensures consistent rib height and shape regardless of subsequent variations in shaft size or tape layers, eliminating the need for post-installation adjustment.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The protruding feature is merged with the grip core as a single integrated component. This integration ensures that the reminder rib maintains its predetermined shape and position relative to the grip surface, preventing height inconsistencies that would otherwise result from separate assembly components.

Inventive Principle:
Principle #5Merging (Combining)

2Manufacturing precision

If the protruding feature is formed as an integral part of the grip core, then consistent rib height is achieved, but the manufacturing process becomes more complex

Engineering Contradiction:
Improverib height consistencyVSAvoidgrip core structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The manufacturing process utilizes parameter changes in the molding conditions to create the protruding feature. By adjusting mold temperature, injection pressure, or material viscosity during specific phases of the molding cycle, the protruding feature is formed integrally with the grip core without requiring additional manufacturing steps or complex tooling.

Inventive Principle:
Principle #35Parameter changes

3Difficulty of detecting and measuring

If the protruding feature protrudes from the outer surface without shaft insertion, then hand alignment is detectable even when not on shaft, but the grip may not conform to PGA regulations

Engineering Contradiction:
Improvealignment detectabilityVSAvoidregulation compliance
Core Design Contradiction:
Difficulty of detecting and measuringVSReliability

Solution Approach 1:

The protruding feature is designed with specific local characteristics - a predetermined shape that protrudes a controlled distance from the outer surface - that provide detectable hand alignment cues. The local geometry is optimized to be detectable by the golfer's fingers while maintaining overall compliance with PGA regulations regarding grip modifications.

Inventive Principle:
Principle #3Local quality

AI summary

A golf club grip with reminder rib is provide that has a hollow main body having an inner diameter configured to fit to a shaft, wherein the hollow main body comprises a protruding feature that extends along a length of the hollow main body. The protruding feature protrudes from an outer surface of the hollow main body without requiring the shaft to be inserted in the hollow main body. By not requiring the golf grip to be on the shaft in order to cause a protrusion above the outer surface of the main body, the reminder rib formed by the protruding feature can be ensured to be about 0.040 inches, thus conforming to current rules of golf.
