Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual placement and preset script paths are used for UAV launch, then collision avoidance can be achieved, but the time consumption and operational complexity increase significantly
Solution Approach 1:
The patent replaces manual mechanical placement operations with an automated computer system that calculates optimal launch positions and sequences using algorithms. The system automatically determines launch parameters including position, time, and sequence for multiple UAVs, substituting human-operated mechanical processes with computational automation to reduce time consumption while maintaining collision avoidance reliability
Solution Approach 2:
The system performs preliminary calculation of optimal launch positions and sequences before actual launch. By pre-computing the launch plan including position assignment and timing sequence, the system prepares all necessary parameters in advance, enabling efficient execution during actual launch without time-consuming on-site adjustments or manual coordination
2Productivity
If multiple UAVs are launched simultaneously to form a formation quickly, then assembly efficiency improves, but collision risk increases in complex environments
Solution Approach 1:
The patent segments the launch process into distinct phases and assigns different launch sequences to different groups of UAVs. By dividing the fleet into multiple launch batches with staggered timing, the system enables parallel processing of launch operations while maintaining safe separation between simultaneously active UAVs, thus improving overall assembly efficiency without compromising collision avoidance
Solution Approach 2:
The system dynamically adjusts launch parameters including position, time, and sequence based on real-time environmental conditions and UAV states. This dynamic optimization allows the system to maximize launch parallelism and assembly efficiency while adaptively maintaining safe operational distances and collision avoidance strategies throughout the launch process
3Manufacturing precision
If a specified formation is required before task execution, then task performance quality improves, but the launch process becomes more complex and time-consuming
Solution Approach 1:
The system performs preliminary calculation of optimal launch positions that directly correspond to the desired formation configuration. By pre-computing the exact launch parameters needed to achieve the target formation, the system eliminates complex post-launch adjustment procedures and reduces launch process complexity while maintaining high formation accuracy
Solution Approach 2:
The patent replaces complex manual coordination and on-site formation adjustment operations with automated computer-based calculation and control systems. The system uses algorithms to automatically determine launch parameters that achieve the desired formation, substituting complex mechanical coordination processes with computational solutions that simplify the overall launch process while maintaining precision
