1Adaptability or versatility

If existing approaches for determining flight paths are used, then the flight path determination is simpler, but the adaptability to changes in circumstances and properties of flying regions is insufficient

Engineering Contradiction:
Improveadaptability to changes in circumstancesVSAvoidflight path determination complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The flight path determination system dynamically adapts to changing circumstances by continuously monitoring signal transmission states and environmental conditions during flight. The system modifies flight paths in real-time based on detected changes, transforming a static path planning approach into a dynamic adaptive system that responds to evolving conditions in the flying region.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system employs feedback mechanisms by assessing signal transmission states and environmental conditions during flight, then using this information to adjust and optimize subsequent flight path segments. This closed-loop approach enables the system to learn from actual flight conditions and improve path determination adaptability while managing complexity through iterative refinement.

Inventive Principle:
Principle #23Feedback

2Reliability

If existing approaches for determining flight paths are used, then the computational requirements are lower, but the performance in signal transmission and navigation is suboptimal

Engineering Contradiction:
Improvesignal transmission reliabilityVSAvoidflight path determination complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary assessments of signal transmission states and environmental conditions before finalizing flight path segments. By evaluating potential path options against predicted conditions and selecting routes that optimize signal transmission reliability in advance, the system improves navigation performance while managing computational complexity through proactive planning.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system changes key parameters such as flight altitude, speed, and route selection based on real-time signal transmission conditions and environmental factors. By dynamically adjusting these parameters to optimize signal reliability and navigation performance, the system achieves superior operational outcomes while the underlying complexity is managed through parameter-based adaptation rather than structural complexity.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If flight paths are determined without real-time signal transmission assessment, then the navigation is faster, but the signal transmission reliability deteriorates

Engineering Contradiction:
Improvesignal transmission reliabilityVSAvoidflight path determination time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs partial real-time assessments of signal transmission states at critical decision points during flight rather than continuous full evaluations. By assessing key parameters selectively and adjusting flight paths at strategically chosen moments, the system maintains signal transmission reliability while minimizing the time lost to assessment activities, achieving a balance between reliability and efficiency.

Inventive Principle:
Principle #16Partial or excessive action
