High Elongation Golf Ball Coating for Spin and Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing golf ball coatings fail to provide suitable properties for enhancing short game spin and durability without affecting performance in other club shots.
Innovation Solution
A golf ball coating comprising a one-component polyurethane dispersion (PUD) with an elongation of at least 400% is applied as a primer layer, which can be water or solvent-based, and optionally includes multiple layers, to improve backspin and durability by utilizing polyurethane-filled micelles in a continuous water phase with specific viscosity and particle size, compatible with ionomer cover materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing golf ball coatings are used, then manufacturing simplicity is maintained, but short game spin and durability are insufficient
Solution Approach 1:
The patent changes the key parameter of elongation from conventional values to at least 400%, which fundamentally alters the coating's mechanical properties. This parameter change enables the coating to provide enhanced short game spin and durability while maintaining compatibility with existing manufacturing processes and ionomer cover materials.
Solution Approach 2:
The patent employs composite material formulation by combining polyurethane dispersion with specific elastomers and ionomer particles. This composite approach creates a coating that achieves superior short game spin and durability properties while remaining manufacturable using conventional golf ball coating techniques.
2Reliability
If high elongation coating is applied, then short game spin improves, but coating viscosity increases
Solution Approach 1:
The patent carefully balances the viscosity parameter to ensure it remains within sprayable ranges despite incorporating high elongation components. By controlling viscosity while achieving 400%+ elongation, the coating maintains applicability through conventional spray methods while delivering improved short game spin performance.
Solution Approach 2:
The patent achieves high elongation properties specifically in the coating matrix where needed for spin generation, while controlling overall viscosity for manufacturability. This localized optimization allows the coating to exhibit high elasticity where required without compromising overall coating flow and sprayability.
3Strength
If polyurethane dispersion is used, then elongation reaches 400%, but particle size control becomes critical
Solution Approach 1:
The patent specifies precise particle size parameters (average diameter 0.01-1.0 micrometers) to achieve the desired 400% elongation while ensuring uniform coating application. This precise control of particle size distribution is critical for obtaining both the high elongation property and smooth coating finish.
Solution Approach 2:
The patent utilizes polyurethane dispersion with controlled porosity and particle structure to achieve high elongation. The dispersed micellar structure allows the coating to stretch and deform significantly (400% elongation) while maintaining particle integrity and uniform distribution during application.
