Golf Club Grip Adhesion via Intermediary Outer Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf club grips face issues with low adhesion between the grip body and the grip end, leading to reduced durability, especially when materials with low affinity are used for the inner and outer layers.
Innovation Solution
A golf club grip design where the cylindrical outer layer is interposed between the inner layer and the grip end, ensuring high affinity materials are used for the outer layer and grip end to enhance adhesion, thereby improving durability and allowing for lighter weight options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If different materials are used for the cylindrical inner layer and cylindrical outer layer to reduce weight and cost, then weight and cost are reduced, but the adhesion between the grip body and grip end deteriorates
Solution Approach 1:
The cylindrical outer layer serves as an intermediary component between the cylindrical inner layer and the grip end. It is interposed in the space between the butt side end edge of the cylindrical inner layer and the grip end, providing a bonding interface that ensures strong adhesion between materials with low affinity, thereby preventing grip end detachment while allowing weight reduction through material differentiation
Solution Approach 2:
The grip employs a composite structure with different materials for the cylindrical inner layer and cylindrical outer layer. The outer layer is specifically designed to have high affinity with the grip end material, creating a multi-material composite system that optimizes both weight and adhesion properties
2Reliability
If the cylindrical outer layer is interposed between the inner layer and grip end to improve adhesion, then adhesion and durability are improved, but the structural complexity increases
Solution Approach 1:
The cylindrical outer layer performs multiple functions simultaneously: it provides structural coverage over the cylindrical inner layer, creates a bonding interface with high affinity for the grip end, and prevents detachment of the grip end. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in structural complexity
