Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single electromagnetic field detector is used, then the device complexity is low, but the detection precision and localization capability are insufficient
Solution Approach 1:
The electromagnetic field detector is divided into multiple detectors arranged in an array, where each detector independently measures the electromagnetic field. This segmentation enables precise localization through triangulation while maintaining relatively simple individual detector structures, thus resolving the contradiction between detection precision and device complexity.
2Loss of information
If multiple detectors are arranged in an array, then the localization capability is improved, but the device complexity increases
Solution Approach 1:
The detector array segments the localization function across multiple simple detector units, each performing basic electromagnetic field measurement. The collective arrangement provides localization capability through geometric triangulation, avoiding the need for complex individual detector designs while achieving enhanced localization performance.
3Productivity
If the detector array is used in areas with high demand, then the signal detection capacity is enhanced, but the system complexity increases
Solution Approach 1:
The system segments the detection capacity across multiple independent detector units that can be distributed and scaled independently. Each unit maintains simple operation while the array collectively provides enhanced detection capacity for high-demand areas, resolving the contradiction between productivity and system complexity.

Implementation Method 1
The EIT effect may be experienced when a probe laser and a coupling laser are used to excite electrons of an atomic medium to a Rydberg state (that is, an elevated energetic state) through a sequential, coherent excitation process
Implementation Method 2
A time-varying electromagnetic field incident at the atomic medium may then cause a time-varying distortion in the energy level structure of the atomic medium
