Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If public transport frequency is reduced in low-population areas, then transportation cost is reduced, but transportation efficiency deteriorates
Solution Approach 1:
The patent merges multiple route schedules into a coordinated system where branch line schedules are optimized based on main line schedules. By combining routes and optimizing transfers between them, the system achieves better resource utilization and maintains transportation efficiency even with reduced frequency in low-population areas.
Solution Approach 2:
The schedule creation system dynamically adjusts branch line schedules based on main line schedule changes and transfer demand. This dynamic optimization allows the system to adapt to varying conditions, maintaining efficiency while reducing costs in low-population areas through flexible, data-driven schedule adjustments.
2Ease of manufacture
If existing schedule drawing methods are used for multiple routes, then individual route schedules are created, but transfer efficiency among routes deteriorates
Solution Approach 1:
The system merges the schedule creation process for multiple routes into a unified optimization framework. By simultaneously considering main line and branch line schedules and their transfers, the system creates coordinated schedules that improve transfer efficiency while maintaining ease of creation through automated optimization.
Solution Approach 2:
The schedule optimization system uses feedback from transfer data and schedule performance to continuously improve schedule coordination. By analyzing transfer patterns and adjusting schedules based on this feedback, the system achieves efficient transfers while keeping the creation process manageable through iterative optimization.
3Loss of energy
If public transport is used less frequently in aging and depopulating areas, then operational cost is reduced, but service reliability deteriorates
Solution Approach 1:
The system dynamically optimizes schedules to maintain reliability even with reduced frequency. By using real-time data and continuous optimization, the system ensures that services are reliably coordinated when they do operate, adapting to changing conditions while maintaining service quality in aging and depopulating areas.
Solution Approach 2:
The optimization system uses feedback from operational data to maintain service reliability. By continuously monitoring and adjusting schedules based on actual performance and transfer patterns, the system ensures reliable service delivery even with reduced frequency, allowing cost reduction without sacrificing reliability.
