Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If MM wave radar detectors are used to detect physical actions, then detection capability is improved, but power consumption increases
Solution Approach 1:
The patent extracts the high-power signal processing functions from the MM wave radar detector and relocates them to a remote server. The detector only performs low-power functions (signal acquisition and preliminary processing), while the server handles computationally intensive tasks (signal analysis, action recognition, and response generation). This extraction resolves the contradiction by maintaining detection capability at the detector while eliminating the power consumption burden of complex processing from the detector.
Solution Approach 2:
The patent introduces a network communication infrastructure as an intermediary between the MM wave radar detector and the remote server. This intermediary enables the detector to offload processing tasks without requiring direct local processing capability, thus maintaining low power consumption while achieving sophisticated detection and analysis through the server.
2Loss of time
If signal data processing is performed locally, then response time is improved, but device complexity increases
Solution Approach 1:
The patent extracts complex signal processing and analysis functions from the detector device and relocates them to a remote server. This extraction maintains relatively simple detector hardware while achieving comprehensive action recognition through server-based processing, thus resolving the contradiction between response time and device complexity.
3Measurement precision
If full signal processing is performed at the detector, then analysis accuracy is improved, but power dissipation increases
Solution Approach 1:
The patent segments the signal processing workflow into two distinct stages: (1) low-power signal acquisition and preliminary processing at the detector, and (2) high-computation signal analysis and action recognition at the remote server. This segmentation maintains analysis accuracy through comprehensive server-based processing while minimizing power dissipation at the detector by performing only essential local functions.
Solution Approach 2:
The patent extracts the computationally intensive signal analysis functions from the detector and relocates them to the server. This extraction preserves analysis accuracy by performing complete processing at the server while eliminating the power dissipation burden from the detector, thus resolving the contradiction between accuracy and power consumption.
