Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a rotorcraft is equipped with an image capturing function for automatic landing, then the landing precision and automation level are improved, but the privacy protection and portrait right protection deteriorate
Solution Approach 1:
The image capturing function is extracted and removed from the rotorcraft system. The patent explicitly states that the rotorcraft is designed without any image capturing devices, thereby eliminating the source of privacy infringement while maintaining landing capability through alternative means
Solution Approach 2:
A ground-based position recognition system acts as an intermediary between the rotorcraft and the landing location. The system uses multiple cameras positioned on the ground to track and recognize the rotorcraft's position, allowing automatic landing control without requiring cameras on the rotorcraft itself
2Object-affected harmful factors
If a rotorcraft without image capturing function is used to protect privacy, then the privacy protection is improved, but the landing control capability and positioning accuracy deteriorate
Solution Approach 1:
Multiple ground-based cameras are merged into a coordinated system that works together to track the rotorcraft from different angles and positions. This combination of multiple sensing elements compensates for the absence of onboard cameras and achieves accurate position recognition
Solution Approach 2:
The position recognition system transitions from a single-point onboard camera to a multi-point ground-based camera network, adding spatial dimensions to the observation. This dimensional change allows the system to track the rotorcraft's position and orientation through geometric calculations based on multiple viewing angles
3Measurement precision
If multiple image capturing portions are deployed for accurate position recognition, then the positioning precision is improved, but the device complexity and cost increase
Solution Approach 1:
The ground-based camera system uses the rotorcraft's own reflected light and natural environmental lighting to create recognizable images, without requiring additional active markers or complex retro-reflective materials on the rotorcraft. The system processes the rotorcraft's visual features directly as they appear in the natural environment
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure and efficient landing of rotorcrafts without image capturing functions, protecting privacy and facilitating landing in environments with limited GPS signals, while ensuring safe package delivery and operation in various weather conditions.
Implementation Method 1
the position recognition portion may be configured to include image capturing portions provided at a plurality of positions on the landing portion, and recognize the position of the rotorcraft with respect to the landing portion on a basis of a result of image capturing performed by the image capturing portions
Implementation Method 2
a distance measuring portion that measures a distance from the landing portion to the rotorcraft

AI summary
A drone loaded with a package takes off from a takeoff device and uses a GPS system to fly to a user house that is a delivery destination of the package as the destination. Further, when the drone approaches the user house that is the destination, the flight of the drones is switched from autonomous navigation using the GPS system to remote control performed by a landing device and an in-house control device installed in the user house. The drone lands on the landing device by remote control from the landing device and the in-house control device, separates the package, and then returns to the warehouse using the GPS system and lands on the takeoff device.
