Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radar is used for tracking and monitoring objects, then measurement precision and detection capabilities are improved, but device complexity increases due to multiple communication circuits and radar signal processing requirements
Solution Approach 1:
The system divides the tracking and monitoring function into two separate circuits: a first circuit for conventional communication frequencies and a second circuit for radar frequencies. This segmentation allows each circuit to be optimized for its specific function, improving measurement precision while managing device complexity through functional separation.
Solution Approach 2:
The electronic tag is designed with dual communication capability, serving both as a conventional communication device and a radar transponder. This multi-functionality allows the same device to operate in multiple frequency bands and communication modes, reducing the need for entirely separate systems while maintaining high measurement precision.
2Adaptability or versatility
If multiple communication circuits are integrated in smart devices, then communication versatility is improved, but ease of operation deteriorates due to complex signal management and coordination
Solution Approach 1:
The communication system is segmented into distinct frequency bands handled by separate circuits. The first circuit manages conventional communication frequencies while the second circuit handles radar frequencies, allowing independent optimization and simplified operation of each circuit without interference from the other.
Solution Approach 2:
The electronic tag acts as an intermediary device that receives radar signals from radar transmitters and responds with modulated signals containing location and movement information. This intermediary role simplifies the overall system operation by providing a standardized interface between radar systems and tracked objects.
