Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual diagnostic tests are used to diagnose damaged antennas and hardware connections, then diagnostic accuracy can be achieved, but diagnostic time increases and device downtime prolongs
Solution Approach 1:
The wireless networking device performs self-diagnostics by automatically transmitting data packets through its own WNICs and antennas, measuring RSSI values, and identifying defective components without requiring external manual testing equipment or technicians. The device tests itself using its built-in communication capabilities.
Solution Approach 2:
The system performs diagnostic tests proactively before complete failure occurs by continuously monitoring RSSI values and comparing them against threshold criteria. This preliminary detection allows for early identification of deteriorating antenna or connection conditions.
2Difficulty of detecting and measuring
If manual diagnostic tests are performed by technicians, then detailed component identification is possible, but device downtime increases and productivity decreases
Solution Approach 1:
The wireless networking device autonomously identifies defective antennas and WNICs by measuring RSSI values during self-transmitted data packets and comparing results against predefined thresholds, eliminating the need for technician intervention in the diagnostic process.
Solution Approach 2:
The system continuously monitors RSSI values during data transmission and provides immediate feedback by comparing measured values against threshold criteria, automatically generating diagnostic results that indicate which antennas or WNICs are defective based on the feedback from the transmission process.
3Productivity
If automated self-test capabilities are implemented, then diagnostic time is reduced and productivity improves, but device complexity increases
Solution Approach 1:
The WNICs serve dual purposes: they perform their primary function of wireless communication for data collection and simultaneously function as test transmitters for diagnostic purposes. The same antennas and communication hardware used for normal operation are reused for self-diagnostics, avoiding the need for separate dedicated test equipment.
Solution Approach 2:
The system incorporates self-diagnostic functionality using existing hardware resources, where the wireless networking device uses its own WNICs and antennas to transmit test data packets and evaluate its own component health, adding diagnostic capability without requiring additional specialized hardware.
4Loss of information
If continuous data collection is maintained during operation, then data loss is minimized, but the risk of undetected component failure increases
Solution Approach 1:
The wireless networking device continuously collects data and performs diagnostic tests during normal operation without interruption. The self-diagnostics occur alongside data collection activities, ensuring that both data gathering and health monitoring proceed continuously without requiring separate maintenance windows or stopping operations.
Solution Approach 2:
The system implements continuous monitoring of RSSI values during data transmission and provides real-time feedback by comparing measurements against thresholds, enabling immediate detection of component degradation while maintaining uninterrupted data collection operations.
