Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing colored golf balls lack excellent spin performance, durability, visibility, stylishness, and elegance, with many falling short in luminosity and weather resistance, particularly those with polyurethane outermost cover layers.
Innovation Solution
A colored golf ball design featuring a core, a cover with multiple layers, and a surface paint layer containing fluorescent dyes, where the outermost cover layer is made of polyurethane and satisfies specific Lab color system conditions for L, a, and b values, ensuring excellent spin performance, durability, and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a high amount of fluorescent pigment (3.0 to 7.0 parts by weight per 100 parts resin) is used in the cover, then visibility is improved, but the color becomes too intense and elegance is lost
Solution Approach 1:
The patent applies local quality by concentrating the fluorescent pigment exclusively in the paint layer applied to the surface of the outermost cover layer, rather than distributing it throughout the entire cover structure. This allows the fluorescent effect to be localized to the surface where visibility is most important, while keeping the outermost cover layer itself transparent or translucent to maintain elegance and allow light transmission.
Solution Approach 2:
The patent uses composite materials by combining a transparent or translucent polyurethane outermost cover layer with a separate paint layer containing the fluorescent pigment. This composite structure allows the cover material to provide durability and spin performance while the paint layer provides the fluorescent visibility effect, resolving the contradiction between intensity and elegance.
2Illumination intensity
If titanium oxide (0.05 to 0.5 part by weight per 100 parts resin) is combined with fluorescent pigment, then visibility is enhanced, but the color becomes too intense and luminosity decreases
Solution Approach 1:
The patent localizes both the fluorescent pigment and titanium oxide exclusively to the paint layer on the surface, rather than incorporating them into the bulk cover material. This localized application provides the visibility enhancement at the surface while preventing the bulk material from becoming overly intense or losing luminosity.
Solution Approach 2:
The patent uses a paint layer as a superficial coating that copies or reproduces the fluorescent effect on the surface without requiring the entire cover structure to contain the pigment. This allows the underlying transparent cover to maintain its luminosity while the surface paint layer provides the enhanced visibility.
3Reliability
If the outermost cover layer is made of polyurethane material, then spin performance and durability are improved, but achieving elegant coloration with good visibility is difficult
Solution Approach 1:
The patent employs composite materials by using a polyurethane outermost cover layer for durability and spin performance, combined with a separate paint layer containing fluorescent pigment and titanium oxide for coloration and visibility. This composite approach allows each layer to fulfill its specific function without compromise.
Solution Approach 2:
The patent applies local quality by restricting the colored and fluorescent components to the surface paint layer, while keeping the polyurethane cover layer itself transparent or translucent. This allows the cover material to provide its mechanical benefits while the surface layer provides the desired coloration and visibility.
4Shape
If a pale color tone is used in the cover, then elegance is achieved, but visibility and brightness are insufficient
Solution Approach 1:
The patent resolves this contradiction by creating a dual-nature surface: the outermost cover layer maintains a transparent or translucent appearance that conveys elegance, while the paint layer applied to its surface contains concentrated fluorescent pigment that provides enhanced visibility and brightness. The elegance comes from the transparent cover, while the visibility comes from the fluorescent paint layer.

AI summary
In a colored golf ball having a core, a cover of at least one layer encasing the core, and a layer of paint applied to a surface of an outermost layer of the cover, the outermost cover layer and/or the paint layer is colored with a fluorescent dye, and the golf ball itself has a color tone which satisfies specific ranges in the Lab color system. The ball is endowed with an excellent spin performance and durability, an appearance characterized by outstanding visibility, stylishness and elegance, and an excellent weather resistance.
