Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional transportation vehicles (buses, subways, taxis) are used in remote areas, then passenger accessibility is limited due to fixed schedules and routes, but if demand-responsive transportation is implemented, then operational flexibility improves while service coverage and reliability may deteriorate
Solution Approach 1:
The patent implements dynamic route generation by allowing the system to automatically create and adjust transportation routes based on real-time passenger demand data. The route generation unit dynamically determines optimal paths between pickup and dropoff locations, enabling the transportation service to adapt flexibly to changing demand patterns while maintaining reliable coverage through systematic route planning
Solution Approach 2:
The system changes operational parameters such as routes, stops, and vehicle allocation dynamically based on demand. The route generation unit adjusts route parameters (pickup/dropoff locations, sequence of stops) according to passenger requests, transforming the fixed-parameter conventional system into a variable-parameter demand-responsive system that maintains reliability through optimized parameter selection
2Adaptability or versatility
If demand-responsive transportation operates without fixed lines, then operational flexibility improves, but route planning complexity and management difficulty increase
Solution Approach 1:
The route generation unit automatically performs route planning and optimization without requiring manual intervention. The system self-generates routes by processing passenger demand data, calculating optimal paths, and determining pickup/dropoff sequences autonomously, thereby reducing management complexity while maintaining high route flexibility
Solution Approach 2:
The patent replaces manual route planning mechanisms with an automated computational system. The route generation unit uses algorithms to substitute human-driven route design with machine-based optimization, reducing planning complexity through systematic automated processing of spatial and temporal parameters
3Measurement precision
If polygon service areas are defined with precise coordinate information, then service area accuracy improves, but the time and computational resources required for area setting increase
Solution Approach 1:
The system performs preliminary route generation and service area definition based on historical demand patterns and predefined geographic boundaries. By pre-establishing polygon service areas using coordinate information before actual operations, the system achieves high measurement precision for service area accuracy while reducing real-time setup time through advance preparation
