Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If appearance inspection or illuminating test is used, then the inspection process is simple, but the high-frequency characteristics of the antenna device cannot be determined
Solution Approach 1:
The patent introduces electromagnetic wave signals as an intermediary medium to detect the high-frequency characteristics of the antenna device. The detection device uses electromagnetic wave signal generating units, output elements, receiving elements, and measuring units to transmit and receive electromagnetic waves that interact with the antenna device under test, enabling indirect measurement of high-frequency properties without direct contact or complex physical inspection
Solution Approach 2:
The patent replaces traditional mechanical inspection methods (appearance inspection, illuminating tests) with an electromagnetic field-based detection system. Instead of using physical probes or visual examination, the system uses electromagnetic wave generation, transmission, and reception to assess the antenna device's high-frequency characteristics, substituting mechanical/optical inspection with electromagnetic interaction
2Measurement precision
If electromagnetic wave signal transmission and reception is implemented, then high-frequency characteristics can be determined, but the device complexity increases
Solution Approach 1:
The patent designs the detection device with multi-functional components that can perform multiple operations. The electromagnetic wave signal generating unit can generate signals at different frequencies, the output element can both transmit and receive signals, and the measuring unit can analyze various parameters (phase, amplitude, frequency). This multi-functionality reduces the need for separate dedicated components for each measurement task, thereby managing device complexity while maintaining measurement precision
