Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is transmitted using a shared communication channel for uplink and downlink, then channel resource utilization is improved, but data transport delay increases
Solution Approach 1:
The patent implements dynamic channel allocation where the communication channel switching period is adjusted based on data transmission needs. When downlink data volume exceeds uplink data volume, the system extends the downlink channel period to prioritize data delivery, thereby reducing transport delay while maintaining efficient channel utilization through adaptive resource allocation.
2Productivity
If the terminal device performs advanced processing locally, then channel congestion is reduced, but device complexity and power consumption increase
Solution Approach 1:
The patent enables selective local processing at the terminal device based on data type and processing requirements. Instead of requiring full advanced processing capabilities in all terminal devices, the system allows devices to perform only the necessary processing locally (such as simple data filtering or preprocessing) while more complex processing is performed at the server端, thereby reducing channel congestion without significantly increasing device complexity or power consumption.
3Speed
If the communication channel prioritizes downlink data transmission, then real-time reconstruction of terminal devices is improved, but uplink data transmission delay increases
Solution Approach 1:
The patent implements a periodic channel switching mechanism that alternates between downlink-prioritized periods and uplink-prioritized periods. During downlink periods, the channel allocates more resources to downlink transmission for real-time reconstruction data delivery. During uplink periods, the system compensates by prioritizing uplink transmission to deliver sensor data and feedback. This periodic alternation ensures that both directions receive adequate service over time, maintaining reconstruction speed while preventing excessive uplink delay.

AI summary
A communication system includes a terminal device including a sensing device, a network system including wireless communication, and a server that transmits to and receives from the terminal device through the network system via wireless communication. The communication system includes a controller that dynamically controls a transport ratio of an uplink channel to a downlink channel, considering a direction from the terminal device to the server is an uplink channel and a direction from the server to the terminal device is a downlink channel, and the controller adjusts the transport ratio according to a condition of data transport or a type of data transport.
