Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual assignment of landing devices to landings is performed, then assignment can be completed, but the process is laborious and prone to errors
Solution Approach 1:
The patent replaces the manual mechanical assignment process with an automated system using air pressure sensors and electronic communication. The air pressure sensor automatically detects the landing position based on atmospheric pressure variations at different heights, eliminating the need for manual configuration and reducing human error in the assignment process.
2Productivity
If manual assignment of landing devices is performed, then assignment can be completed, but it consumes significant time and resources
Solution Approach 1:
The landing device performs self-identification and self-assignment through the air pressure sensor. When installed, the device automatically measures the local air pressure, which corresponds to its specific landing height, and communicates this information to the controller. This self-service mechanism eliminates the need for time-consuming manual assignment procedures.
3Extent of automation
If air pressure sensors are added to landing devices, then automatic assignment is enabled, but device complexity increases
Solution Approach 1:
The patent utilizes a physical parameter (air pressure) that naturally varies with landing height to enable automatic identification. By adding a simple air pressure sensor that measures this existing environmental parameter, the system achieves automation without requiring complex mechanical or electronic identification mechanisms. The air pressure value serves as a unique identifier for each landing position.
