Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light accumulating fluorescent substance is coated on flat surface of substrate, then manufacturing is simple, but thickness is insufficient and brightness is inadequate
Solution Approach 1:
The patent transitions from a two-dimensional flat coating to a three-dimensional convex structure. The light accumulating fluorescent substance is formed in a convex shape with height extending from the substrate surface, creating vertical dimensionality that increases material thickness and light emission capacity while maintaining manufacturing feasibility through molding processes.
Solution Approach 2:
The light accumulating fluorescent substance is embedded within a transparent resin material that is further embedded in the substrate. This nested structure allows multiple layers to be integrated, with the convex portion of fluorescent substance surrounded by transparent resin, which is then integrated into the substrate matrix, creating a multi-layer nested configuration that enhances brightness.
2Illumination intensity
If light accumulating fluorescent substance is coated as thin layer, then manufacturing is easy, but stereoscopic emission of light cannot be achieved
Solution Approach 1:
The invention introduces vertical height dimension to the light accumulating fluorescent substance by forming convex portions that extend upward from the substrate surface. This three-dimensional configuration enables stereoscopic light emission as light is emitted from multiple height levels rather than a single flat plane, creating depth and volume in the light output.
Solution Approach 2:
The light accumulating fluorescent substance is formed with convex, curved surfaces rather than flat planes. The convex portions have rounded top surfaces and curved side surfaces, which facilitate omnidirectional light emission and create stereoscopic visual effects. The curvature allows light to be emitted from multiple angles and heights, enhancing the three-dimensional appearance.
3Device complexity
If light accumulating material has insufficient thickness, then structure is simple, but visual appeal and fanciness are lacking
Solution Approach 1:
The patent employs a nested structure where the light accumulating fluorescent substance is embedded in transparent resin, which is then embedded in the substrate. This nested configuration allows the light accumulating material to be surrounded and protected by additional layers, increasing the effective quantity and volume of functional material while integrating it into a complex multi-layer design that enhances visual appeal.
Solution Approach 2:
The invention creates a composite structure combining light accumulating fluorescent substance, transparent resin material, and substrate. This composite configuration allows different materials with complementary properties to be integrated, where the fluorescent substance provides light emission, the transparent resin provides structural support and optical clarity, and the substrate provides the base matrix, collectively enhancing both quantity of functional material and design complexity.
