Engineering Contradiction Analysis
1Ease of operation
If manual loopback tests are performed by hand, then testing can be conducted with basic equipment, but testing time increases and expert knowledge is required
Solution Approach 1:
The test system performs self-testing by automatically generating test signals, routing them through the device under test via loopback circuitry, and analyzing the results without requiring external expert operators. The artificial intelligence module autonomously determines test parameters and evaluates outcomes, enabling the system to test itself.
Solution Approach 2:
The artificial intelligence module dynamically adjusts test signal parameters such as frequency, amplitude, and modulation characteristics based on the specific device being tested and detected anomaly patterns. This adaptive parameter adjustment optimizes test effectiveness while reducing the need for expert knowledge.
2Device complexity
If manual loopback tests are performed by hand, then testing can be conducted with simple setup, but extensive user knowledge about sub-systems is required
Solution Approach 1:
The artificial intelligence module serves as an intermediary between the test signal generation and analysis processes. It automatically determines appropriate test parameters, routes signals through appropriate loopback paths, and interprets results, thereby shielding the user from complex technical knowledge requirements while maintaining systematic testing.
Solution Approach 2:
The system incorporates feedback loops where the artificial intelligence module continuously monitors test results and adjusts subsequent test parameters accordingly. This automated feedback mechanism replaces the need for expert human judgment in interpreting test outcomes and determining next testing steps.
3Productivity
If automated testing with artificial intelligence is implemented, then testing speed increases and expert knowledge is not required, but system complexity increases
Solution Approach 1:
The artificial intelligence module is designed to handle multiple test types and device configurations through a single unified platform. It can adapt to different signal processing devices, generate appropriate test signals, and analyze various failure modes, thereby justifying its complexity through multi-functional capability that replaces multiple specialized testing systems.
Solution Approach 2:
The artificial intelligence module is pre-trained with extensive knowledge about signal processing device architectures, common failure modes, and optimal test parameters. This preliminary preparation of test strategies and parameter sets enables rapid automated testing without requiring the module to learn during operation, thus managing complexity through advance preparation.
4Reliability
If loopback circuitry transmits signals through multiple paths, then comprehensive testing is achieved, but signal routing complexity increases
Solution Approach 1:
The loopback circuitry is segmented into distinct functional paths, each dedicated to testing specific device components or signal processing stages. This segmentation allows the artificial intelligence module to selectively activate only the necessary test paths for each testing scenario, reducing the effective complexity while maintaining comprehensive testing coverage through systematic path selection.
