Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If radar systems transmit large amounts of raw data, then data completeness is maintained, but transmission time increases and object detection speed decreases
Solution Approach 1:
The patent extracts and removes redundant information from radar data before transmission. The encoder identifies and eliminates unnecessary data elements while preserving critical object detection information, thereby reducing transmission time without compromising detection speed.
Solution Approach 2:
The patent transforms radar data parameters by applying compression algorithms that modify data representation. The encoder changes data parameters through encoding schemes that reduce data volume while maintaining essential information for object detection, resolving the contradiction between transmission time and detection speed.
2Measurement precision
If radar systems process and transmit high-volume data, then measurement accuracy is maintained, but energy consumption increases
Solution Approach 1:
The patent extracts only the essential data elements required for accurate object detection, removing redundant information that consumes energy during processing and transmission. This extraction process maintains measurement precision while significantly reducing energy consumption.
Solution Approach 2:
The patent applies parameter changes through data compression that optimizes the energy-efficiency tradeoff. The encoder transforms data parameters to reduce transmission energy requirements while preserving the precision needed for accurate object detection.
3Reliability
If radar systems transmit uncompressed data, then data integrity is maintained, but transmission bandwidth requirements increase
Solution Approach 1:
The patent extracts and removes redundant data elements that do not contribute to object detection accuracy. This extraction maintains data integrity for essential information while reducing the bandwidth requirements and simplifying the transmission system.
Solution Approach 2:
The patent applies parameter changes through encoding transformations that reduce data volume while preserving integrity. The encoder modifies data parameters to achieve compression without losing critical information, thereby reducing transmission bandwidth requirements and system complexity.
