Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golf balls with glossy coatings reflect light, hindering player concentration and causing yellowing over time, which affects performance and aesthetic appearance.
Innovation Solution
A matte coating composition for golf balls using a synthetic fatty acid resin derived from dehydrated castor oil, combined with a UV stabilizer, storage stabilizer, and silica, along with a hexamethylene diisocyanate resin as a curing agent, to reduce gloss and prevent yellowing without compromising physical properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a glossy coating is applied to the golf ball surface, then the driving distance is improved, but light reflection occurs which hinders player concentration and causes yellowing over time
Solution Approach 1:
The patent applies a matte coating with specific light absorption characteristics instead of a glossy coating. The coating composition includes pigments and fillers that absorb rather than reflect light, changing the surface optical properties from high reflectivity to low reflectivity, thereby eliminating the harmful light reflection effect while maintaining driving distance performance
Solution Approach 2:
The patent uses a composite coating composition containing multiple components including polymers, pigments, fillers, and additives. This composite material provides both the matte appearance to reduce light reflection and the necessary durability to prevent yellowing, while simultaneously maintaining the driving distance characteristics of the golf ball
2Reliability
If a glossy coating is used to maintain driving distance, then the ball performance is preserved, but the surface yellowing occurs upon UV exposure over time
Solution Approach 1:
The patent converts the potential harm of UV exposure by incorporating UV absorbers and hindered amine light stabilizers into the coating composition. These additives absorb UV radiation and prevent it from degrading the polymer matrix, thereby converting the harmful UV effect into a protectible parameter and preventing yellowing while maintaining long-term aesthetic appearance
Solution Approach 2:
The patent introduces UV stabilizers and antioxidants as intermediary substances between the UV radiation and the coating matrix. These intermediaries absorb or neutralize the harmful UV energy before it can cause yellowing, acting as a protective barrier that maintains both performance and aesthetic appearance over extended periods
3Illumination intensity
If a matte coating is applied to reduce gloss, then visibility is improved for precise hitting, but the coating composition complexity increases
Solution Approach 1:
The patent achieves the matte appearance by controlling the particle size, shape, and concentration of fillers and pigments in the coating composition. By adjusting these parameters within specific ranges, the coating provides optimal light scattering properties for improved visibility while maintaining a manageable composition complexity that allows for practical manufacturing
