Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a one-dimensional flight path is used for inspection, then the flight vehicle can maintain a constant height and distance, but the inspection accuracy in three-dimensional space is insufficient
Solution Approach 1:
The patent transitions from traditional one-dimensional flight paths (constant height and distance) to three-dimensional flight paths that include vertical dimension variations. The flight vehicle operates at different altitudes and positions around the navigation safety facility, enabling comprehensive inspection from multiple spatial perspectives and significantly improving measurement accuracy.
2Productivity
If a dedicated flight vehicle performs inspection flights, then the inspection can be conducted systematically, but the inspection coverage in various flight cases is limited
Solution Approach 1:
The system enables the dedicated flight vehicle to operate in three-dimensional space with variable heights and positions, allowing it to inspect navigation safety facilities under multiple flight scenarios including different altitudes, approaches, and spatial configurations, thereby significantly enhancing adaptability and inspection coverage.
Solution Approach 2:
The flight path is designed to be dynamic rather than static, allowing the flight vehicle to adjust its altitude, position, and trajectory according to different inspection requirements and facility characteristics, enabling systematic inspection across diverse flight cases.
3Reliability
If periodic inspection is conducted, then the safety of flight vehicles is ensured, but the inspection accuracy in complex three-dimensional environments is insufficient
Solution Approach 1:
The patent implements periodic inspections using three-dimensional flight paths that capture navigation signal characteristics from multiple spatial positions and altitudes. This multi-perspective data collection significantly improves the accuracy of facility status assessment while maintaining the periodic inspection schedule for flight vehicle safety.

AI summary
An apparatus and a method for inspecting navigation safety facilities by using a flight vehicle are disclosed. The method for inspecting navigation safety facilities by using a flight vehicle comprises the steps of: defining a three-dimensional flight path for a flight vehicle so that same passes through navigational safety facilities; receiving a navigation signal value from the navigation safety facilities and GPS data of the flight vehicle, the navigation signal value and the GPS data being measured by the flight vehicle automatically flying along the defined three-dimensional flight path; analyzing the navigation signal value so as to estimate the distance and the angle of the flight vehicle viewed from the navigation safety facilities; and inspecting the navigation safety facilities according to whether the coordinates of the flight vehicle identified by the GPS data are included in an area formed by the distance and the angle.
