Drone Landing Stage Marker Layout for Open-Hatch Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing takeoff and landing assist apparatuses for flying objects, such as drones, suffer from decreased landing accuracy due to markers being divided or not recognized properly when the opening lid is open.
Innovation Solution
The takeoff and landing assist apparatus is designed with a stage and an opening where the edge of the opening does not cross the markers, ensuring the markers remain intact and recognizable even when the lid is open. Additionally, a visual recognition assist surface on the lid with a different color from the markers helps in accurate recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the opening is provided with a lid that can be opened and closed, then loading and unloading to and from the flying object is facilitated, but the markers may be divided when the lid is open, resulting in decreased landing accuracy
Solution Approach 1:
The opening is segmented into two parts: a fixed portion and a movable lid portion. The lid can be opened independently to facilitate loading and unloading operations, while the fixed portion maintains the markers intact for accurate landing recognition.
Solution Approach 2:
Different regions of the takeoff and landing surface have different functions: the region with markers is designed to remain static and intact for landing recognition, while the opening region is designed to be movable for loading and unloading operations.
2Stability of the object's composition
If the marker is formed to extend across the lid and the rest of the surface, then the marker provides continuous visual reference, but the markers are divided when the lid is open, causing the flying object to fail to recognize them properly
Solution Approach 1:
The marker system is segmented such that markers are placed only on the fixed portion of the takeoff and landing surface, not on the movable lid. This ensures markers remain continuous and recognizable when the lid is opened for loading and unloading operations.

AI summary
A stage has a takeoff and landing surface. The takeoff and landing surface has an opening through which loading and unloading to and from a flying object is carried out. The takeoff and landing surface has a plurality of markers formed thereon. Each marker is a figure or the like for identifying a relative position between the flying object and the stage. The opening is formed in the takeoff and landing surface such that an edge of the opening does not cross the markers.
