Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotorcrafts equipped with cameras for autonomous landing pose privacy concerns due to the potential capture of individuals in the surrounding environment, necessitating a solution for rotorcrafts without image capturing functions to safely land on a destination.
Innovation Solution
A rotorcraft landing device with a landing portion, position recognition mechanism, and remote control system that allows rotorcrafts without image capturing functions to land safely by using image capturing portions, distance measuring, and movable members to control the landing process, ensuring secure and private operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a rotorcraft is equipped with an image capturing function for autonomous landing, then the landing automation is improved, but the privacy protection deteriorates due to potential capture of individuals in the surrounding environment
Solution Approach 1:
The image capturing function is extracted from the rotorcraft and relocated to the ground-based landing device. The position recognition portion on the ground captures images to recognize the rotorcraft's position and guides landing, eliminating the need for cameras on the rotorcraft itself and thus preventing privacy infringement during flight while maintaining autonomous landing capability
Solution Approach 2:
A ground-based landing device serves as an intermediary between the rotorcraft and the landing process. This intermediary contains the position recognition portion that captures images and processes positioning information, allowing the rotorcraft to land automatically without having its own image capturing function, thereby resolving the contradiction between automation and privacy protection
2Object-affected harmful factors
If the position recognition is performed using image capturing portions on the ground, then the privacy protection is improved, but the device complexity increases due to additional ground-based recognition systems
Solution Approach 1:
The ground-based landing device performs multiple functions: it serves as both the landing target for the rotorcraft and the position recognition system. The position recognition portion is integrated into the landing device structure, utilizing the same platform for both functions, which reduces overall system complexity despite adding ground-based capabilities
Solution Approach 2:
The position recognition function is merged with the landing device rather than being a separate system. The landing device combines the physical landing structure with the position recognition portion, creating an integrated system that reduces complexity compared to having independent rotorcraft cameras and separate ground recognition systems

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.
