Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate measurement equipment and facilities are used to test antenna modules, then measurement accuracy is improved, but test time increases and costs increase
Solution Approach 1:
The patent merges the antenna module under test with the measurement function by integrating a detection circuit directly into the communication module. The communication module transmits test signals through its own antenna elements and detects received signals using integrated detection circuits, eliminating the need for separate external measurement equipment and facilities while maintaining measurement capability within the device itself
Solution Approach 2:
The antenna module performs self-testing by using its own communication module to transmit test signals and its own detection circuit to measure received signals. The processor compares measured values with reference values stored in memory to automatically determine antenna element abnormalities, enabling the system to test itself without external intervention or specialized equipment
2Measurement precision
If separate measurement equipment and facilities are used to test antenna modules, then measurement capability is improved, but installation costs increase
Solution Approach 1:
The patent combines the measurement function with the communication module by integrating detection circuits directly into the existing antenna module structure. This eliminates the need for separate external measurement equipment and facilities, reducing installation complexity and costs while maintaining the ability to perform accurate antenna element tests within the device itself
Solution Approach 2:
The system enables self-diagnosis by using the communication module's own transmission and reception capabilities to test antenna elements. The detection circuit measures received test signals and the processor compares results with stored reference values, allowing the device to automatically identify abnormalities without requiring external measurement equipment or specialized installation infrastructure
