Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If fluorescent pigment and titanium oxide are added to the cover-forming material, then visibility is improved, but elegance and luminosity deteriorate due to intense coloration
Solution Approach 1:
The patent optimizes the concentration parameters of fluorescent pigment (0.01-0.10 parts by weight per 100 parts resin) and titanium oxide (0.1-0.5 parts by weight per 100 parts resin) to achieve a balance between visibility and elegance. This parameter optimization prevents excessive color intensity while maintaining bright appearance and luminosity.
Solution Approach 2:
The patent creates a composite cover material combining polyurethane resin with specific amounts of fluorescent pigment and titanium oxide. This composite formulation achieves synergistic effects where the resin matrix distributes the pigments uniformly, providing both visibility enhancement and elegant appearance without overwhelming color intensity.
2Illumination intensity
If high amount of fluorescent pigment is used, then visibility is improved, but color becomes too intense and luminosity decreases
Solution Approach 1:
The patent precisely controls the fluorescent pigment concentration at 0.01-0.10 parts by weight per 100 parts resin, which is significantly lower than conventional amounts. This optimized parameter range provides sufficient visibility while preventing excessive color intensity that would reduce luminosity and elegance.
3Illumination intensity
If colored cover is applied to improve visibility and style, then spin performance and durability may deteriorate
Solution Approach 1:
The patent formulates a composite cover material where polyurethane resin serves as the base (100 parts by weight), combined with fluorescent pigment (0.01-0.10 parts) and titanium oxide (0.1-0.5 parts). This composite structure maintains the mechanical properties and spin performance of polyurethane while incorporating colorants for visibility and style.
Solution Approach 2:
The patent applies coloration locally to the cover layer while maintaining the core and intermediate layers in their standard formulations. This localized quality change allows the cover to provide visibility and style without compromising the overall spin performance and durability provided by the multi-piece construction.
