Color-Coded Vertiport Navigation for Branched UAM Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing line tracers for urban air mobility (UAM) struggle to guide aircraft through branched paths at vertiports, leading to instability in navigation.
Innovation Solution
A navigation system using color codes that divides aircraft paths into sub-paths at branch points and assigns distinct colors to each sub-path, allowing for accurate combination and guidance based on departure and destination points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a typical line tracer operates on a single line, then the navigation is simple to implement, but it cannot perform properly on branched paths at vertiports
Solution Approach 1:
The patent divides the aircraft path at a vertiport into multiple sub-paths based on branch points. Each sub-path is represented by a distinct color code, allowing the navigation system to handle branched paths by selectively combining these segmented sub-paths according to the specific departure and destination points.
2Measurement precision
If color codes are used to represent different sub-paths, then navigation accuracy through vertiports is improved, but the system complexity increases
Solution Approach 1:
The patent assigns distinct color codes to represent different sub-paths at vertiports. The navigation system uses these color codes to visually differentiate and guide aircraft through specific sub-paths, improving navigation accuracy by providing clear visual cues for path selection.
3Reliability
If the line tracer attribute is changed at branch points using colors, then guidance reliability is improved, but the ease of operation decreases
Solution Approach 1:
The patent changes the attribute of the line tracer specifically at branch points using color codes, while maintaining the simple single-line tracer approach for straight paths. This localized application of color coding improves guidance reliability at critical decision points without complicating the overall system operation.

AI summary
Disclosed is a navigation method and system using color codes. The navigation method according to an embodiment of the present disclosure includes: dividing an aircraft path at a vertiport into a plurality of sub-paths based on a branch point; and selectively combining at least some of the plurality of sub-paths and generating a guiding path for an urban air mobility (UAM) to travel at the vertiport based on a departure point and a destination point scheduled for the UAM.
