Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single mirror approach is used for emission enhancement, then the device complexity is reduced, but the manufacturing precision and quality control become insufficient due to discrepancies in material properties and thicknesses
Solution Approach 1:
The single mirror structure is segmented into a dual-mirror configuration with two separate mirrors positioned at specific angles relative to the substrate. This segmentation allows independent optimization and control of each mirror's properties, compensating for material discrepancies and thickness variations to achieve consistent emission enhancement across the substrate surface.
Solution Approach 2:
Each mirror in the dual-mirror system is designed with specific local optical properties and positioning angles tailored to compensate for local variations in substrate thickness and material properties. This local quality approach ensures that emission enhancement is maintained uniformly across different regions of the substrate despite manufacturing variations.
2Reliability
If fabricated substrates with controlled reflectance/transmittance are used, then emission enhancement is achieved, but the quality control process becomes constrictive, time-consuming and complex
Solution Approach 1:
The dual-mirror system is designed to be self-aligning and self-compensating for typical manufacturing variations. The geometric configuration and optical paths are arranged such that the system automatically compensates for moderate deviations in mirror positioning and substrate properties, reducing the need for time-consuming manual quality control adjustments while maintaining reliable emission enhancement.
3Measurement precision
If the substrate design is specific to luminescent species, then measurement precision is improved, but the adaptability to different instruments and species is reduced
Solution Approach 1:
The dual-mirror substrate design employs universal geometric configurations and optical principles that can be adapted to various luminescent species and readout instruments. The mirror angles, positioning, and optical paths are designed to work with different emission wavelengths and detection geometries, allowing a single substrate design to serve multiple applications and instruments while maintaining measurement precision.
