Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple nodes transmit data concurrently to improve communication speed, then data transmission efficiency is improved, but network traffic increases and communication delays occur
Solution Approach 1:
The patent combines data from multiple nodes at relay nodes by synthesizing data destined for the same destination before transmission. This merging approach reduces the number of individual data packets traveling through the network, thereby reducing overall network traffic volume while maintaining efficient data transmission through coordinated relay operations.
Solution Approach 2:
The patent implements preliminary data collection and synthesis at relay nodes before actual transmission to the destination. By aggregating data in advance and managing transmission timing proactively, the system prepares data packets strategically to avoid concurrent transmissions, thus reducing network traffic while maintaining transmission efficiency.
2Productivity
If relay nodes aggregate data to reduce network traffic, then communication efficiency is improved, but transmission wait time increases
Solution Approach 1:
The patent dynamically adjusts transmission timing based on real-time network conditions and data availability at relay nodes. Rather than using fixed aggregation periods, the system adapts its transmission schedule to balance data aggregation benefits with the need for timely delivery, thereby reducing unnecessary wait times while maintaining communication efficiency.
Solution Approach 2:
The patent changes transmission timing parameters and aggregation thresholds dynamically based on network conditions. By adjusting these parameters, the system can optimize the balance between aggregating data to reduce traffic and maintaining quick transmission, thus reducing wait time while preserving communication efficiency.
3Quantity of substance
If data transmission timing is adjusted to concentrate data at relay nodes, then network traffic is reduced, but communication reliability may be affected
Solution Approach 1:
The patent incorporates feedback mechanisms where relay nodes monitor transmission success and network conditions. This feedback allows the system to adjust data concentration strategies dynamically, ensuring that data aggregation for traffic reduction does not compromise reliability. Successful transmissions reinforce the current strategy, while failures trigger adaptive adjustments to maintain communication reliability.

AI summary
A wireless communication terminal in each node intercepts wireless communication among other nodes. When detecting failure in communication, the wireless communication terminal stores corresponding communication data on the node the wireless communication terminal belongs to, and relays the stored data by wireless communication. Transmission timing in each node is determined uniquely to the node, and data are transmitted periodically. In accordance with circumstances, the transmission timing in each node is changed to make the transmission timing in each data generation node earlier and to make the transmission timing in each data relay node later. Thus, a plurality of communication data are collected in data relay nodes. Each data relay node synthesizes a plurality of communication data, and performs relay transmission thereof.
