Engineering Contradiction Analysis
1Ease of operation
If a conventional two-dimensional train graph is used to display timetables, then the display is simple and easy to understand, but physical irrationalities in complex track layouts cannot be visually expressed
Solution Approach 1:
The patent applies dimensionality change by transitioning from a conventional two-dimensional train graph to a three-dimensional space representation. The third dimension represents the vertical layer corresponding to different railway tracks, allowing the display to preserve both the simplicity of 2D visualization and the ability to express complex track layout relationships. Train trajectories are displayed as three-dimensional curves that incorporate time, horizontal position, and vertical track layer information, enabling visual detection of timetable irrationalities that were invisible in 2D representations.
2Device complexity
If train schedule lines are displayed in a two-dimensional train graph, then the graph is easy to create and display, but crossing lines do not indicate irrationality in complicated track layouts
Solution Approach 1:
The patent resolves this contradiction by adding a vertical dimension to represent different railway tracks. Instead of having train schedule lines cross ambiguously in 2D space, the 3D representation shows trains on different tracks at different vertical layers, making it immediately visible when timetable arrangements are physically irrational. The computation apparatus calculates three-dimensional trajectories that incorporate track layer information, ensuring accurate representation without excessive complexity.
3Loss of information
If a three-dimensional display of train trajectories is implemented, then timetable irrationalities can be intuitively recognized, but the computational complexity and data processing requirements increase
Solution Approach 1:
The patent applies preliminary action by having the computation apparatus pre-calculate the three-dimensional trajectories of trains based on timetable data and track layout information before display. The trajectory drawing unit computes the three-dimensional curves in advance, storing the calculated trajectory data for efficient rendering. This approach enables intuitive visualization of timetable irrationalities while managing computational complexity through pre-processing rather than real-time calculation during display operations.
