Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If receiver devices perform object detection and tracking using radar waveforms, then object detection capability is improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent extracts the object detection and tracking processing functions from the receiver device to a dedicated network node (sensing management function). The receiver device only needs to transmit radar waveforms and receive reporting configurations, while the computationally intensive detection and tracking operations are performed remotely at the network node, reducing local device complexity and resource requirements.
Solution Approach 2:
The patent introduces a sensing management function as an intermediary between the receiver device and the object detection process. This intermediary receives radar waveform reports from the receiver device, performs the computationally expensive detection and tracking operations, and returns results to the receiver device, thereby offloading processing burden while maintaining detection capability.
2Measurement precision
If receiver devices perform object detection and tracking using radar waveforms, then object detection capability is improved, but energy consumption increases
Solution Approach 1:
The patent extracts the energy-intensive object detection and tracking processing from the battery-operated receiver device to a powered network node. By transmitting only raw radar waveform data and receiving processed detection results, the receiver device consumes significantly less energy while maintaining full object detection capability through the network node's processing.
3Measurement precision
If receiver devices perform object detection and tracking, then detection functionality is improved, but processing time and computational load increase
Solution Approach 1:
The patent extracts computationally intensive tracking algorithms from the receiver device to a dedicated network node with greater processing power. The receiver device sends radar waveform reports and receives tracking results without performing the complex computations locally, thereby reducing processing cycle consumption and freeing up computational resources for other tasks.
