Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing wireless communication systems are used for drones, then ground-based communication protocols can be applied, but communication stability deteriorates due to 3-dimensional flight movement
Solution Approach 1:
The measurement report control unit dynamically adjusts the measurement report process based on real-time flight information (position, speed, acceleration). When the drone is stationary or moving slowly, measurement reports are transmitted frequently to maintain connection stability. When the drone is moving quickly, the system adapts by adjusting report frequency and threshold criteria to prevent excessive signaling while maintaining communication reliability throughout the 3-dimensional flight space.
2Reliability
If measurement reports are transmitted frequently to maintain connection stability, then communication reliability improves, but network load increases
Solution Approach 1:
The system changes the parameters of measurement report transmission based on flight conditions. The measurement report control unit uses flight information (position, speed, acceleration) to dynamically adjust the threshold for triggering measurement reports. When the drone is stationary, the threshold is set low to trigger frequent reports for connection stability. When the drone is moving, the threshold is adjusted to reduce unnecessary reports, thereby reducing network load while maintaining adequate connection stability.
3Reliability
If measurement report thresholds are set low to ensure connection stability, then communication reliability improves, but the number of measurement reports increases
Solution Approach 1:
The threshold for triggering measurement reports is dynamically adjusted based on flight information. The measurement report control unit monitors the drone's position, speed, and acceleration to determine the appropriate threshold. During stationary phases, low thresholds trigger frequent reports to ensure connection stability. During movement phases, thresholds are raised to reduce the number of reports, thereby reducing network load while maintaining connection stability when most needed.
