Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional detection methods are used, then device simplicity is maintained, but detection efficiency and accuracy are insufficient
Solution Approach 1:
The patent employs metamaterial patterns with composite structures (e.g., stacked metal and dielectric layers) to achieve superior optical properties that enhance detection efficiency. These composite materials enable the generation of structured light beams with characteristics not achievable by conventional materials alone.
Solution Approach 2:
The sample box is divided into multiple functional regions with distinct patterns (metamaterial patterns, polarization patterns, lattice patterns) that perform specific optical functions. This segmentation allows each region to contribute to the overall detection efficiency while maintaining a modular structure.
2Measurement precision
If simple light interaction is used, then device complexity is reduced, but measurement precision of biomaterials is insufficient
Solution Approach 1:
Different regions of the sample box are assigned specific optical patterns with tailored properties. The metamaterial patterns in certain regions provide enhanced light confinement, while polarization patterns in other regions provide polarization control, allowing each local region to contribute its specific quality to the overall measurement precision.
Solution Approach 2:
The optical patterns are designed to manipulate light parameters (wavelength, polarization state, spatial distribution) to optimize interaction with biomaterials. By changing these optical parameters through the patterns, the detection accuracy is enhanced without requiring fundamental changes to the detection principle.
3Speed
If rapid detection is implemented, then detection speed is improved, but detection accuracy may be compromised
Solution Approach 1:
The optical patterns are pre-configured in the sample box to automatically generate structured light beams and control light interaction with biomaterials upon light source activation. This preliminary arrangement of optical elements ensures that the detection process rapidly proceeds through optimized optical paths, achieving both speed and accuracy simultaneously.
