Engineering Contradiction Analysis
1Speed
If wireless communication is used to transmit captured images during flight, then real-time image transmission is enabled, but communication quality varies depending on position leading to interrupted or low-bit-rate transmission
Solution Approach 1:
The system performs preliminary acquisition of communication quality information for multiple candidate flight paths before generating the final flight plan. This allows the system to predict and avoid areas with poor communication quality in advance, ensuring reliable image transmission throughout the flight.
Solution Approach 2:
The system changes flight path parameters by selecting from multiple candidate paths based on their communication quality characteristics. When the current path shows deteriorating communication quality, the system transitions to an alternative path with better communication conditions, maintaining stable transmission.
2Reliability
If the flight path is changed to improve communication quality, then image transmission reliability is improved, but the imaging task completion may be affected
Solution Approach 1:
The flight path generation system performs multiple functions simultaneously: it evaluates both communication quality and imaging task requirements when generating candidate paths. This multi-functional approach ensures that selected paths satisfy both transmission reliability and imaging completion objectives without requiring separate optimization processes.
Solution Approach 2:
The system adjusts flight path parameters by generating multiple candidate paths with different characteristics and selecting the optimal one that balances communication quality and imaging task completion. This parameter optimization ensures both reliability and productivity requirements are met.
3Reliability
If communication quality information is acquired for multiple candidate flight paths, then the optimal path for image transmission can be selected, but the system complexity increases
Solution Approach 1:
The flight path selection process is segmented into distinct steps: acquiring communication quality information for multiple candidate paths, evaluating each path's suitability, and selecting the optimal path. This segmentation makes the complex decision-making process more manageable and systematic.
Solution Approach 2:
Communication quality information for multiple candidate paths is acquired in advance before final path selection. This preliminary action allows the system to have all necessary information ready for optimal decision-making without adding complexity during real-time execution.
