Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If active luminescent mode glass is used to achieve luminous effect, then illumination performance is improved, but cost increases significantly
Solution Approach 1:
The patent replaces expensive active luminescent glass with a cost-effective combination of ordinary glass and simple optical components (light extraction component with microstructure, interlayer with specific refractive index). This substitution uses inexpensive materials and straightforward lamination processes to achieve the desired luminous effect without the high cost of active luminescent glass.
Solution Approach 2:
The patent introduces an interlayer with specific refractive index between the light extraction component and the glass bodies as an intermediary element. This interlayer mediates light propagation and enables total internal reflection, achieving efficient light extraction and diffusion without requiring expensive active luminescent materials.
2Illumination intensity
If light extraction component is added to enhance light extraction, then illumination brightness is improved, but device complexity increases
Solution Approach 1:
The patent merges the light extraction component, interlayer, and glass bodies into a single integrated laminated structure. This combination achieves enhanced light extraction and diffusion functionality while maintaining a relatively simple overall structure that can be manufactured using standard glass lamination processes.
Solution Approach 2:
The light extraction component uses a thin film or coating with microstructure on its surface, and the interlayer uses a thin laminated layer with specific refractive index. These thin film structures achieve the desired optical effects without adding significant structural complexity or thickness to the overall glass assembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The glass assembly improves illumination brightness and user experience by enhancing light extraction and diffusion, maintaining aesthetic performance without additional complexity or cost.
Implementation Method 1
the refractive index of the interlayer is smaller than that of an adjacent layer in the direction toward the second glass body, so that incident light introduced from the second glass body is totally reflected toward the second glass body
Implementation Method 2
at least totally reflected in the second glass body
Implementation Method 3
the refractive index of the interlayer is smaller than that of an adjacent layer
