Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional optical materials are used, then the refractive index is low, but the dispersion is reduced and design flexibility is limited
Solution Approach 1:
The patent employs a composite structure combining metamaterial lens layer with OLED layer. The metamaterial lens layer provides high refractive index and controlled dispersion characteristics, while the OLED layer contributes to optical performance. This composite approach enables simultaneous optimization of refractive index, dispersion, and design flexibility that cannot be achieved with conventional single materials.
Solution Approach 2:
The patent utilizes metamaterials to fundamentally change the optical parameters (refractive index and dispersion) by manipulating the structural parameters of the lens layer. By adjusting the geometry, material composition, and structural parameters of the metamaterial lens, the optical characteristics can be precisely controlled to achieve high refractive index with manageable dispersion.
2Reliability
If the refractive index is increased to improve optical performance, then the dispersion increases, but the design flexibility is reduced
Solution Approach 1:
The metamaterial lens layer employs local quality by having different regions or structures within the lens layer provide different optical functions. Certain areas can be optimized for high refractive index while other areas manage dispersion characteristics, allowing simultaneous optimization of multiple optical parameters in different zones of the same lens structure.
3Volume of moving object
If conventional materials are used, then the optical device size is large, but the refractive index is low
Solution Approach 1:
By changing the fundamental optical parameters through metamaterials, the patent achieves high refractive index in a compact form factor. The metamaterial lens layer's unique structural properties enable strong light bending and focusing effects with minimal material thickness, dramatically reducing device size compared to conventional materials while maintaining or enhancing optical performance.
