Solution Overview

Problem

Existing display systems for air traffic control struggle to predict abnormal approaches between mobile objects and correct trajectories to avoid potential collisions, especially when displaying traveling conditions three-dimensionally.

Innovation Solution

A display control device and method that estimate predicted trajectories of multiple mobile objects based on track structure data and control information, identify abnormal approach periods, and display a two-dimensional coordinate system to facilitate trajectory correction and avoid overlapping with abnormal approach regions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If three-dimensional display mode is used to display traveling conditions of multiple mobile objects, then the display can show complex movement routes and intersections, but the air traffic controller cannot easily predict abnormal approaches and correct trajectories to avoid collisions

Engineering Contradiction:
Improvedisplay capabilityVSAvoidprediction and correction ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent transforms the three-dimensional display of mobile object trajectories into a two-dimensional representation. By projecting the three-dimensional movement routes onto a two-dimensional plane with coordinate axes representing position and time, the system maintains the ability to display complex trajectories while making abnormal approaches more visually apparent and easier to predict. The two-dimensional format allows controllers to more easily compare trajectories and identify potential conflicts.

Principle #17Another dimension (Dimensionality change)

2Ease of operation

If two-dimensional plane display is used for mobile object trajectories, then prediction of abnormal approaches becomes easier, but the display cannot effectively show complex three-dimensional movement patterns and intersections

Engineering Contradiction:
Improveprediction easeVSAvoiddisplay capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent segments the display into multiple two-dimensional planes, each representing the traveling conditions of individual mobile objects. By dividing the complex three-dimensional scenario into separate two-dimensional representations, the system maintains prediction ease for each individual trajectory while the ability to display multiple planes simultaneously provides comprehensive coverage of all mobile objects, effectively handling complex movement patterns.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If detailed trajectory information is displayed for all mobile objects, then collision prediction accuracy improves, but the display complexity and information overload increase

Engineering Contradiction:
Improveprediction accuracyVSAvoiddisplay complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies different display characteristics to different regions and elements on the display. Important information such as abnormal approach regions is highlighted with distinct visual characteristics (different colors, markers, or patterns), while less critical trajectory information is displayed with standard characteristics. This local differentiation maintains prediction accuracy for critical areas while reducing overall display complexity and information overload.

AI summary

A display control device includes processing circuitry to estimate a second mobile object as a mobile object having an abnormal approach period out of a plurality of relevant mobile objects, to make a display device display a two-dimensional coordinate system formed by a first coordinate axis representing positions from a start point to an end point of a first predicted trajectory by distances and a second coordinate axis representing a time, a line indicating the first predicted trajectory, and an abnormal approach region indicating ranges of the position and the time of the second mobile object, and to make the display device display a display component, and upon receiving input information for moving the display component, to correct the first predicted trajectory so that the line indicating the first predicted trajectory does not overlap with the abnormal approach region.
