Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensing mode switching is implemented to meet diverse sensing service requirements, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic sensing mode switching where the network device can flexibly transition between different sensing modes (first sensing mode with full functionality and second sensing mode with reduced functionality) based on real-time service requirements. This dynamic adjustment allows the system to adapt to varying sensing needs while managing complexity through controlled state transitions rather than maintaining all capabilities simultaneously.
Solution Approach 2:
The patent changes key parameters including sensing signal transmission configuration, echo signal reception configuration, and processing capability parameters to switch between sensing modes. By modifying these parameters dynamically, the system achieves adaptability for different sensing services while avoiding the need for completely separate system configurations, thereby managing complexity.
2Adaptability or versatility
If multiple sensing modes are supported with full parameter configurations, then sensing service versatility is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts and separates the essential sensing functionality from the full sensing mode configuration. The second sensing mode is designed to perform basic sensing tasks with reduced parameter configurations, extracting only the necessary elements for minimal viable sensing operation. This reduces signaling overhead by transmitting fewer parameters while maintaining core sensing capabilities.
Solution Approach 2:
The system dynamically adjusts parameter configuration transmission based on the selected sensing mode. When operating in the second sensing mode, the network device transmits reduced parameter configurations compared to the first sensing mode. This dynamic parameter transmission adapts to service requirements and significantly reduces signaling overhead while maintaining versatility through mode switching.
3Adaptability or versatility
If sensing mode switching is performed frequently to adapt to changing conditions, then sensing service flexibility is improved, but switching time and system stability are worsened
Solution Approach 1:
The patent performs preliminary configuration setup where the network device pre-configures multiple sensing modes and their associated parameters before actual sensing operations begin. This preliminary action allows the system to switch between modes more quickly during operation, as the configuration framework is already established, reducing the time penalty associated with frequent mode switching.
Solution Approach 2:
The system implements dynamic mode switching with optimized transition mechanisms that minimize disruption to ongoing sensing operations. By designing the switching mechanism to be dynamic and efficient, the system can adapt to changing conditions while limiting the time loss during transitions, maintaining both flexibility and operational continuity.
