Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UAV control is implemented through remote control devices using traditional communication methods (Wi-Fi, Bluetooth), then the control system remains simple and direct, but the communication coverage is limited and stability deteriorates over distance
Solution Approach 1:
The patent introduces a base station as an intermediary component between the remote control device and the UAV. The base station receives control signals from the remote control device and transmits them to the UAV, enabling stable communication over long distances through the cellular network infrastructure. This mediator resolves the contradiction by providing reliable communication without requiring the remote control device itself to have high transmission power or complex protocols.
Solution Approach 2:
The patent transitions the communication dimension from direct short-range wireless (Wi-Fi/Bluetooth) to cellular network infrastructure. By utilizing the existing cellular base station network, the system achieves extended coverage and improved stability without increasing the complexity of the UAV or remote control device hardware.
2Area of stationary object
If UAV control uses cellular network base stations for extended coverage, then communication coverage and stability improve, but the connection establishment process becomes more complex
Solution Approach 1:
The patent implements preliminary actions by having the UAV send a random access request to the base station before actual control begins, and by having the base station pre-establish the communication channel. The connection success information is sent to the remote control device in advance, allowing the system to prepare for control transmission before actual operations begin. This reduces the complexity during active control phases.
Solution Approach 2:
The patent incorporates feedback mechanisms where the UAV sends connection success information back to the remote control device after establishing communication with the base station. This feedback loop allows the remote control device to confirm connection status and initiate control signals appropriately, simplifying the overall connection process through structured information exchange.
3Reliability
If the UAV establishes communication connection with base station first, then communication stability improves, but the time delay in control signal transmission increases
Solution Approach 1:
The patent applies preliminary action by having the UAV establish the communication connection with the base station before actual control operations begin. The random access request and connection establishment happen in advance, so that when control signals need to be transmitted, the communication channel is already ready, minimizing delays during actual control phases.
Solution Approach 2:
The patent maintains continuous communication connection between the UAV and base station throughout the operation. Once the connection is established through random access, it remains active, allowing control signals to be transmitted continuously without repeated connection handshakes, thereby reducing time loss while maintaining reliability.
