Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If phosphorescent materials are used to provide emission in darkness, then visibility in dark environments is improved, but coloration consistency between ambient lighting and darkness deteriorates
Solution Approach 1:
The patent combines phosphorescent materials (for dark emission) with fluorescent pigments (for ambient light reflection) into a single composite material. This merging allows the material to exhibit both phosphorescence in darkness and fluorescent reflection in ambient light, maintaining color consistency across different lighting conditions while providing visibility in dark environments.
Solution Approach 2:
The invention creates a composite material comprising both phosphorescent and fluorescent components. The phosphorescent portion provides sustained emission in darkness, while the fluorescent portion reflects ambient light to match the perceived color. This composite structure resolves the contradiction by integrating multiple material types with complementary optical properties into a unified composition.
2Duration of action of moving object
If phosphorescent materials are used to provide persistent emission, then duration of action is improved, but color matching between light and dark conditions deteriorates
Solution Approach 1:
The patent merges phosphorescent materials (providing persistent emission) with fluorescent pigments (providing color matching in ambient light) into a single composite material. This combination allows the material to maintain its perceived color in both ambient lighting and darkness, while the phosphorescent component ensures long persistence time for visibility in dark environments.
Solution Approach 2:
The invention utilizes the color-changing properties of fluorescent pigments to match the emission color of phosphorescent materials under ambient light conditions. The fluorescent component is selected to reflect or emit light in the same wavelength range as the phosphorescent material, ensuring color consistency across different lighting conditions while maintaining long persistence time.
3Adaptability or versatility
If separate phosphorescent and fluorescent materials are used, then functional versatility is improved, but device complexity deteriorates
Solution Approach 1:
The patent merges separate phosphorescent and fluorescent materials into a single integrated composite material. This unified composition provides both phosphorescent emission and fluorescent reflection functions simultaneously, eliminating the need for separate material layers or components. The result is a simplified application process and single-step manufacturing while maintaining the functional versatility of both material types.
Solution Approach 2:
The composite material achieves multi-functionality by incorporating both phosphorescent and fluorescent properties into a single material system. This universal material can be applied in a single coating or treatment step to provide both ambient light reflection and dark emission functions, reducing the complexity of applying multiple separate materials while maintaining broad functional versatility.
