Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display systems for air traffic control struggle to predict abnormal approaches between mobile objects, making it difficult for air traffic controllers to anticipate potential collisions or close encounters.
Innovation Solution
A display control device and method that estimates predicted trajectories of mobile objects, identifies potential abnormal approaches by determining distances and positions based on track structure data and control information, and displays these in a two-dimensional coordinate system with enhanced components indicating critical areas, facilitating the prediction of abnormal approaches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a three-dimensional display mode is used to show traveling conditions of multiple mobile objects, then the display can represent complex trajectory intersections and shared courses, but it becomes difficult for air traffic controllers to predict abnormal approaches between mobile objects
Solution Approach 1:
The patent transforms the three-dimensional display into a two-dimensional display while preserving the ability to represent complex trajectory relationships. By projecting mobile object positions and trajectories onto a two-dimensional plane with enhanced visual indicators, the system maintains adaptability for displaying multiple objects and their interactions while improving predictability through clearer visual cues for abnormal approaches
Solution Approach 2:
The patent employs color changes and enhanced display components to indicate abnormal approaches between mobile objects. By using distinct colors or visual enhancements for trajectories that may result in abnormal approaches, the system draws air traffic controllers' attention to potential conflicts, thereby improving predictability while maintaining the versatility to display complex multi-object scenarios
2Adaptability or versatility
If multiple two-dimensional planes are displayed to show traveling conditions of different mobile objects, then the display can represent individual trajectories, but the complexity of the display increases making it harder to predict abnormal approaches
Solution Approach 1:
The patent merges multiple two-dimensional planes into a single integrated two-dimensional display. By combining the representation of multiple mobile objects and their trajectories into one cohesive view with enhanced visual indicators, the system maintains the ability to represent individual trajectories while reducing display complexity and improving abnormal approach predictability

AI summary
A display control device acquires a first predicted trajectory of a selected mobile object and a plurality of second predicted trajectories, estimates an abnormal approach mobile object as a mobile object having a period in which a distance from the selected mobile object is less than or equal to a predetermined reference value out of the plurality of relevant mobile objects and estimates the position of the abnormal approach mobile object in the abnormal approach period, and makes a display device display a two-dimensional coordinate system formed by a first coordinate axis representing a position in the first predicted trajectory by a distance from a start point and a second coordinate axis representing a time and a line indicating the first predicted trajectory and to make the display device display an enhanced display component that indicates the position of the abnormal approach mobile object in the abnormal approach period.
