Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cellular network is used only for communication, then communication functionality is maintained, but sensing data collection capability is lost
Solution Approach 1:
The patent extends the cellular network's radio electromagnetic wave signal to serve dual purposes: traditional communication functions and environment sensing capabilities. The same network infrastructure is utilized to collect sensing data such as user actions, gestures, breathing monitoring, and environmental conditions, thereby achieving multi-functionality without adding separate dedicated sensing infrastructure.
Solution Approach 2:
The patent introduces dynamic configuration of sensing parameters and data collection strategies based on network conditions, device capabilities, and application requirements. The sensing data collection process is made adaptable through configurable parameters that can be adjusted in real-time, allowing the system to optimize between communication performance and sensing accuracy.
2Quantity of substance
If sensing data is collected from all devices, then comprehensive sensing coverage is achieved, but network data capacity is exceeded
Solution Approach 1:
The patent extracts and processes sensing data at the edge devices (user equipment and access network devices) before transmitting to the core network. Local processing filters, aggregates, and pre-processes raw sensing data to extract only essential information, significantly reducing the data volume that needs to be transmitted and managed by the core network while maintaining comprehensive sensing coverage.
Solution Approach 2:
The patent segments the sensing data collection and processing function across multiple levels: user equipment performs local sensing and initial processing, access network devices perform regional aggregation and further processing, and core network elements perform centralized management. This segmentation distributes data management complexity across the network hierarchy rather than concentrating it at the core.
3Reliability
If sensing data is reported to core network element, then centralized data collection is achieved, but data transmission overhead increases
Solution Approach 1:
The patent introduces access network devices as intermediary elements between user equipment and core network elements for sensing data transmission. These intermediaries aggregate sensing data from multiple devices, perform local processing and filtering, and then transmit consolidated data to the core network, reducing the number of direct transmissions required and lowering overall transmission overhead while maintaining centralized collection reliability.
Solution Approach 2:
The patent performs preliminary processing, filtering, and aggregation of sensing data at the edge devices and access network elements before transmission to the core network. By preparing and condensing data in advance, the system reduces the volume and frequency of transmissions required, thereby lowering energy consumption while ensuring data is ready for reliable centralized collection.
