Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate measurements are performed for different polarization directions, then measurement precision is improved, but measurement time increases
Solution Approach 1:
The patent combines multiple detection functions into a single measurement process by using a detection region that can simultaneously detect terahertz electromagnetic waves with different polarization directions. This allows the system to measure characteristics under multiple polarizations in one go, eliminating the need for separate measurements for each polarization direction while maintaining detection precision.
Solution Approach 2:
The detection region is designed with universal capability to detect various types of terahertz electromagnetic waves with different polarization directions. This multi-functional detection region can handle both horizontal and vertical polarization waves simultaneously, enabling the system to perform multiple measurement tasks through a single integrated structure.
2Measurement precision
If multiple polarization directions are measured separately, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple detection systems into a single integrated detection region that can handle different polarization directions simultaneously. This consolidation reduces the number of separate components needed while maintaining the ability to detect and measure various polarization characteristics with high accuracy.
Solution Approach 2:
The detection region is designed as a universal component that can detect terahertz electromagnetic waves with different polarization directions without requiring separate specialized detectors for each polarization type. This multi-functional design simplifies the overall device structure while preserving detection accuracy.
3Quantity of substance
If positional shifts are used for detection, then measurement coverage is improved, but measurement precision deteriorates
Solution Approach 1:
The detection region is designed with universal detection capability that covers multiple polarization directions simultaneously without requiring positional shifts. This allows the system to maintain a fixed position while still measuring various characteristics under different polarizations, eliminating the trade-off between coverage and precision.
