Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing wireless communication systems are used for devices flying in three-dimensional space, then the system structure remains simple and compatible with current standards, but communication stability and reliability deteriorate due to the inability to accommodate 3D movement patterns
Solution Approach 1:
The patent implements dynamic adjustment of measurement report parameters based on the terminal device's flight state. The measurement report control unit dynamically modifies reporting behavior according to whether the device is in hovering or moving state, enabling the system to adapt to changing 3D motion patterns while maintaining communication stability.
Solution Approach 2:
The patent changes key communication parameters (measurement report intervals, triggering conditions) based on the terminal's flight information. By adjusting these parameters according to flight state (hovering vs. moving), the system optimizes communication performance for 3D space operations without requiring complete system redesign.
2Measurement precision
If measurement report frequency is increased to track 3D position changes, then positioning accuracy improves, but network load and signal transmission frequency increase
Solution Approach 1:
The patent applies partial action by adjusting measurement report frequency according to flight state. During hovering, measurement reports are transmitted at lower frequency or suppressed entirely, while during movement, reporting frequency is increased. This partial adjustment approach achieves necessary positioning accuracy only when needed, reducing overall energy consumption.
Solution Approach 2:
The patent implements periodic measurement report transmission with variable periods based on flight state. The measurement report control unit adjusts the periodicity dynamically - using longer periods during hovering and shorter periods during movement - thereby achieving positioning accuracy requirements while minimizing energy expenditure on signal transmission.
3Reliability
If measurement report process is continuously activated to maintain communication stability, then communication reliability improves, but power consumption and network load increase
Solution Approach 1:
The patent dynamically controls the measurement report process based on real-time flight state information. The measurement report control unit activates or suppresses measurement reports according to whether the terminal is hovering or moving, maintaining communication reliability only when necessary and reducing power consumption during stable hovering periods.
Solution Approach 2:
The terminal device autonomously adjusts its measurement report behavior based on its own flight state without continuous network control. The acquisition unit获取s flight information and the measurement report control unit independently decides when to transmit reports, enabling the device to self-regulate power consumption while maintaining communication reliability.
