Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Wi-Fi or point-to-point links are used for drone communication, then the system can operate in various environments, but the signal reliability deteriorates and range is limited
Solution Approach 1:
The patent introduces a 5G network as an intermediary communication infrastructure between the drone and ground control systems. The 5G network acts as a mediator that provides reliable backhaul communication, allowing the drone to maintain stable connections in indoor and obstructed environments where traditional Wi-Fi fails, thus resolving the contradiction between reliability and environmental adaptability
Solution Approach 2:
The patent leverages the technical parameters of 5G networks, specifically utilizing network slicing to create dedicated communication channels with guaranteed quality of service. By changing the communication paradigm from local Wi-Fi to 5G cellular networks with slice isolation, the system achieves higher reliability while maintaining versatility across different deployment scenarios
2Length of stationary object
If Wi-Fi or point-to-point links are used for drone communication, then the system can be implemented with existing infrastructure, but the communication range decreases and video quality degrades
Solution Approach 1:
The patent transitions the communication architecture from a two-dimensional local area network (Wi-Fi) to a three-dimensional cellular network architecture. By utilizing the 5G network's macro-cellular coverage and hierarchical cell structure, the system extends communication range beyond the limitations of local infrastructure while maintaining signal quality through network slicing and dedicated bearers
3Ease of operation
If drones use simple flight control systems for maneuverability, then the drone design becomes simpler and more reliable, but the navigation precision and hazard detection capability are insufficient
Solution Approach 1:
The patent implements a feedback-driven navigation system where the drone continuously monitors environmental data (visual, acoustic, thermal) and feeds this information back to the flight control system. This real-time feedback enables the simple quadcopter design to achieve precise navigation and hazard detection by dynamically adjusting its behavior based on sensor inputs and predicted routes
Solution Approach 2:
The system performs preliminary actions by predicting the user's route in advance and pre-planning the drone's navigation path. The flight control system anticipates potential hazards along the predicted route and executes avoidance maneuvers before conflicts occur, enabling simple hardware to achieve sophisticated navigation through predictive algorithms
Data Source
AI summary
A system pairs a 5G-connected drone to a 5G-enabled user-controlled device. The system sets a predicted route for the 5G-connected drone to navigate. A portion of this route is indoors and matches an actual route of the user-controlled device. The system then causes the 5G-connected drone to commence navigating the predicted route. The system receives environmental data from the area surrounding the 5G-connected drone on the predicted route measured by a set of onboard sensors of the 5G-connected drone. Using the received environmental data and a deviation of the predicted route from the actual route traversed by the user-controlled device, the system determines that an alternate route for the 5G-connected drone exists and sets the alternate route. The system generates a notification based on the environmental data indicating hazards on the alternate route and transmits the notification over a 5G network to the user-controlled device.
