Golf Ball Cover with Fluorescent Colorant for High Chroma Saturation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional golf balls are difficult to distinguish from a distance, leading to potential penalties, and existing solutions compromise on visibility, distinguishability, and high-grade appearance due to the use of titanium dioxide, which affects chroma saturation and masking ability.
Innovation Solution
A golf ball with a cover that does not include titanium oxide but features a fluorescent colorant and a paint layer containing polarizing composite particles, achieving high chroma saturation and polarization properties for enhanced visibility and distinguishability while maintaining a high-grade appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a large amount of pigment is dispersed in the cover to achieve color, then visibility and distinguishability are improved, but high-grade looking deteriorates
Solution Approach 1:
The patent uses fluorescent colorants that emit light at wavelengths different from excitation wavelengths, creating vivid colors that are visible from distance. This allows the ball to be highly visible without using large amounts of conventional pigments that would compromise appearance quality.
Solution Approach 2:
The patent combines fluorescent colorants with titanium dioxide in specific ratios, creating a composite cover material that achieves both visibility and high-grade looking. The composite structure allows the fluorescent colorant to provide visibility while titanium dioxide maintains the aesthetic appearance.
2Device complexity
If titanium dioxide is blended in a small amount to maintain masking ability, then high-grade looking is preserved, but chroma saturation deteriorates
Solution Approach 1:
The patent changes the chemical composition parameters by introducing fluorescent colorants alongside titanium dioxide. This parameter change allows the system to achieve high chroma saturation (S≥25) even with limited titanium dioxide content, resolving the contradiction between masking ability and color saturation.
Solution Approach 2:
The fluorescent colorant acts as an intermediary that enhances chroma saturation without requiring large amounts of titanium dioxide. It mediates between the need for masking ability and the desire for vivid color, allowing both requirements to be satisfied simultaneously.
3Quantity of substance
If the core color is revealed on the surface, then material usage is reduced, but visibility and distinguishability deteriorate
Solution Approach 1:
The fluorescent colorant in the cover creates vivid colors that dominate the visual appearance, masking the core color effectively. This allows the cover to be thinner or use less material while still maintaining high visibility and distinguishability from distance.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
