Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex protocol stack structure is used in 3GPP wireless communication networks, then transmission reliability is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent segments the data transmission process into two distinct parts: (1) data collection from Ambient IoT devices by the first communication node, and (2) data forwarding by the first communication node to the second communication node. This segmentation allows the Ambient IoT devices to have simplified protocols while maintaining reliable transmission through the more capable first communication node.
Solution Approach 2:
The first communication node acts as an intermediary between Ambient IoT devices and the second communication node. It receives data from devices with ultra-low capabilities, processes and manages the transmission, and forwards to the destination, thereby shielding the devices from protocol complexity while ensuring reliable delivery.
2Reliability
If a complex protocol stack structure is used in 3GPP wireless communication networks, then transmission reliability is improved, but power consumption increases
Solution Approach 1:
The patent segments the computational and transmission burden from the Ambient IoT devices to the first communication node. Devices only perform simple data collection and transmission to the first node, while the first node handles protocol processing and forwarding, thereby reducing device power consumption while maintaining end-to-end transmission reliability.
Solution Approach 2:
The first communication node serves as an intermediary that consumes power for protocol processing and data management, allowing Ambient IoT devices to operate with minimal power consumption. The intermediary absorbs the energy cost of reliable transmission management.
3Device complexity
If simplified transmission processing is used for Ambient IoT devices, then device complexity is reduced, but transmission capability deteriorates
Solution Approach 1:
The first communication node acts as a mediator that compensates for the limited transmission capability of simplified Ambient IoT devices. The device uses simple protocols to communicate with the first node, which then ensures reliable delivery to the second communication node through its own capabilities.
Solution Approach 2:
The first communication node provides self-service by automatically receiving, processing, and forwarding data from Ambient IoT devices without requiring the devices to implement complex transmission protocols. The node independently manages the transmission reliability.
