Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If WIFI protocol is used for control signaling transmission, then data transmission rate is improved, but transmission reliability deteriorates due to interference and channel occupation in non-authorized frequency bands
Solution Approach 1:
The patent divides the communication functions into two separate networks: cellular network for control signaling and WIFI network for data transmission. This segmentation allows each network to be optimized for its specific function, with cellular providing reliable control and WIFI providing fast data transfer, thereby resolving the contradiction between transmission rate and reliability.
Solution Approach 2:
The patent introduces a base station as an intermediary that receives control signaling from the controller via cellular network, processes it, and then forwards instructions to the UAV. This intermediary structure ensures that control commands are transmitted reliably through the cellular network while data can still be transmitted at high speeds through the WIFI network.
2Reliability
If cellular network is used for control signaling transmission, then transmission reliability is improved, but data transmission rate deteriorates compared to WIFI
Solution Approach 1:
The patent segments communication tasks by assigning control signaling to the cellular network and data transmission to the WIFI network. This allows control commands to be transmitted reliably through cellular while large data payloads are transmitted at high speeds through WIFI, resolving the speed-reliability trade-off.
Solution Approach 2:
The patent changes the communication parameters by selecting different networks for different types of data: cellular network parameters are optimized for reliable control signaling with higher priority and quality of service, while WIFI parameters are optimized for high-speed data transfer, thereby achieving both reliability and speed requirements simultaneously.
3Reliability
If dual-network connection is established, then both control reliability and data transmission rate are improved, but device complexity increases
Solution Approach 1:
The patent makes the UAV communication system multi-functional by enabling it to connect to and operate on two different networks simultaneously. The system can perform control signaling through cellular network and data transmission through WIFI network, achieving universal communication capability that resolves the contradiction between transmission quality and system complexity.
