Multi-layer Golf Grip with Exposed Middle Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional golf grips lack aesthetic variety and effective traction, with corded rubber grips having uniform color and limited texture for improved grip security.
Innovation Solution
A golf grip design featuring multiple colored layers with a contrasting tip, where the under layer, middle layer, and top layer are made from different materials and colors, with the middle layer exposed through buffing or sanding to create a unique aesthetic and textured surface for enhanced grip security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional uniform color grip is used, then manufacturing is simple, but aesthetic variety is limited
Solution Approach 1:
The grip is divided into multiple colored layers (first layer, second layer, third layer) with different materials and colors, where each layer can be independently selected and applied. This segmentation allows for aesthetic variety through different color combinations while maintaining relatively simple manufacturing processes for each individual layer.
Solution Approach 2:
The grip employs composite material construction with at least three different layers made from different materials (e.g., rubber, polyurethane, TPE) and colors. This composite approach enables aesthetic variety through material and color differentiation while each layer can be manufactured using standard processes, balancing aesthetic versatility with manufacturing feasibility.
2Reliability
If corded rubber grip with exposed cord is used, then traction is improved, but texture variety is limited
Solution Approach 1:
Different layers of the grip are assigned different materials and surface characteristics. For example, the second layer may contain exposed cord for enhanced traction, while other layers may have smooth or textured surfaces. This local differentiation provides both improved grip security through strategic cord placement and texture variety across different regions of the grip.
Solution Approach 2:
The multi-layer composite structure allows incorporation of different materials with distinct textural properties. The second layer can be made from corded rubber material for traction, while first and third layers may use different elastomeric materials with varying surface characteristics, providing both grip security and texture variety simultaneously.
3Ease of manufacture
If single color layers are used, then manufacturing is straightforward, but visual appeal is reduced
Solution Approach 1:
The grip is segmented into multiple layers, each with distinct colors, allowing for visual appeal through color differentiation. The manufacturing process remains relatively straightforward as each layer can be produced separately using standard techniques, then assembled in sequence, maintaining ease of manufacture while achieving enhanced visual appeal.
Solution Approach 2:
The use of composite material layers with different colors creates visual appeal through color contrast and layer differentiation. Each layer can be manufactured using conventional processes appropriate for its material type, and the multi-layer assembly provides aesthetic versatility without significantly complicating the overall manufacturing workflow.

AI summary
A golf grip for a golf club includes a cap, a body, a tip, and a grip surface. The body includes an under layer, a top layer, and a middle layer. The under layer includes a first color. The top layer includes a second color, different than the first color. The top layer is disposed on the under layer. The middle layer includes a third material. The middle layer is at least partially disposed between the under layer and the top layer. The tip is a portion of the under layer extending beyond the top layer and the middle layer. The grip surface extends between the cap and the tip. The grip surface is the radially outer surface of the body and includes the top layer, a plurality of exposed portions of the under layer, and a plurality of exposed portions of the middle layer.
