Movement State Presentation Device for Aircraft Conflict Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for displaying the movement states of multiple moving objects, such as aircrafts, fail to clearly distinguish future flight positions, making it difficult to recognize potential conflicts and optimize routes, which affects safety and efficiency in air traffic control and other environments.
Innovation Solution
A system that acquires movement information, predicts future positions of moving objects at multiple time points, and displays both current and future positions sequentially on a display unit, allowing for high visibility and distinguishable representation of each object's trajectory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple future positions of each aircraft are displayed simultaneously on the same screen, then the information completeness is improved, but the visibility and distinguishability of each aircraft's future position deteriorates due to overlapping routes
Solution Approach 1:
The patent applies dimensionality change by displaying multiple future positions of each aircraft along a time axis in sequential order rather than simultaneously on the same plane. The display unit shows future positions at different time points (T1, T2, T3...) sequentially along the time axis, with each future position displayed at a specific time interval. This transforms the problem from a 2D spatial overlap issue to a 1D temporal sequence issue, allowing complete information display while maintaining clear visibility of each aircraft's trajectory.
2Loss of information
If the display interval between future positions is shortened to show more time points, then the information completeness is improved, but the distinguishability between consecutive positions deteriorates
Solution Approach 1:
The patent applies dynamics by making the display interval adjustable and adaptive. The control unit allows the operator to set the display interval between future positions, and the system dynamically adjusts the timing of position displays based on this setting. This dynamic adjustment ensures that even when multiple future time points are displayed, each position remains distinguishable by maintaining appropriate temporal spacing, thus balancing information completeness with visual distinguishability.
3Productivity
If all future positions of all aircraft are displayed at once, then the operational efficiency is improved through comprehensive overview, but the complexity of the display system increases
Solution Approach 1:
The patent applies segmentation by dividing the display of future positions into discrete time-point segments. Instead of displaying all future positions of all aircraft simultaneously, the system segments the display into sequential time points (T1, T2, T3...) along the time axis. Each segment represents a specific future time point for each aircraft, and these segments are displayed in chronological order. This segmentation simplifies the control logic while providing comprehensive operational overview.
