Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If mechanically moving measuring probes are used to sample radiation strength levels, then measurement precision can be achieved, but processing time increases and real-time measurement becomes impossible
Solution Approach 1:
The patent replaces the mechanical moving probe system with a phased array antenna system that uses electronic beam forming and signal processing. Multiple fixed antennas capture signals simultaneously, and digital signal processing computes radiation patterns without mechanical movement, achieving both precision and real-time performance
Solution Approach 2:
The system performs preliminary signal capture using multiple antennas simultaneously across the entire measurement space. All raw signal data is collected first, then processed computationally to generate radiation patterns, eliminating the sequential sampling time of mechanical systems
2Measurement precision
If mechanically moving probes are used for point-by-point measurement, then detailed radiation pattern data can be obtained, but device complexity and operational complexity increase
Solution Approach 1:
The mechanical probe positioning system is replaced with a fixed phased array antenna configuration. The complexity of mechanical movement and positioning is substituted with electronic signal processing and beam forming algorithms, simplifying the physical system while maintaining measurement capability
Solution Approach 2:
The measurement system is segmented into multiple independent antenna elements that simultaneously capture signals from different spatial positions. This parallel segmentation eliminates the need for a single moving probe and reduces mechanical complexity
3Measurement precision
If subsequent evaluation logic is applied to sampled data, then measurement accuracy can be improved, but real-time visualization becomes impossible
Solution Approach 1:
The system establishes continuous real-time signal capture and processing through the phased array. Evaluation computations are performed continuously on incoming signal data streams, enabling both accurate radiation pattern determination and real-time visualization without interruption or delay
