Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If propeller parking control is implemented during hover to fixed-wing transition, then landing safety and precision are improved, but system complexity increases due to additional sensors and computing devices
Solution Approach 1:
The control system is segmented into modular components: sensors (LIDAR, angular position sensors), computing devices for trajectory calculation, and propeller actuation systems. Each component performs a specific function, allowing independent optimization and fault isolation while maintaining overall system reliability during the critical hover to fixed-wing transition.
Solution Approach 2:
The system performs preliminary trajectory calculation and propeller position planning before the actual transition begins. Angular datum is generated in advance, and the trajectory command is computed beforehand, allowing the propellers to be precisely positioned during the transition without real-time computational delays, thereby improving safety.
2Manufacturing precision
If real-time angular datum and trajectory commands are generated during transition, then transition precision is improved, but computational load and response time requirements increase
Solution Approach 1:
Trajectory commands and angular datum are calculated in advance based on pre-stored transition parameters and current flight state. This preliminary computation allows the system to execute the transition with high precision without imposing excessive real-time computational burdens, as the heavy calculation work is performed before the critical transition phase.
Solution Approach 2:
The system replaces complex real-time mechanical feedback adjustments with pre-computed trajectory commands and angular references. By substituting mechanical trial-and-error adjustment with calculated positional data, the system achieves higher transition precision while reducing the need for continuous high-speed computational iterations.
3Reliability
If LIDAR systems and sensor suites are added for obstacle detection, then navigation safety is improved, but device complexity and cost increase
Solution Approach 1:
The LIDAR system and sensor suite serve multiple functions: obstacle detection, angular position measurement, trajectory verification, and environmental mapping. By designing these sensors to perform multiple tasks simultaneously, the system improves navigation safety without proportionally increasing complexity, as the same hardware infrastructure supports various safety-critical functions.
Solution Approach 2:
The sensor suite automatically provides navigation data and obstacle information to the control system without requiring manual intervention or additional processing systems. The LIDAR and angular sensors self-calibrate and self-report their measurements, reducing the burden on external control systems and minimizing the complexity overhead of adding safety-enhancing sensors.
