Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional vehicle operation system uses fixed routing with magnetic markers, then the system provides stable and reliable autonomous travel, but the route cannot be easily changed or adapted
Solution Approach 1:
The patent applies dynamics by making the routing system changeable and adaptable. The control server can dynamically add, modify, or delete connection point information based on operational needs. The movable fence mechanism allows physical route changes without redesigning the entire magnetic marker system, enabling the system to adapt to different routing requirements while maintaining operational simplicity.
2Reliability
If magnetic markers are used for autonomous vehicle guidance, then the system achieves robustness against environmental disturbance, but route changes become difficult to implement
Solution Approach 1:
The patent segments the routing system into fixed magnetic markers for reliable guidance and changeable connection point information for route flexibility. The magnetic markers remain stationary and provide stable positional reference, while the connection point data stored on the control server can be independently modified. This segmentation allows the system to maintain environmental robustness through fixed markers while achieving route adaptability through modular information management.
3Ease of operation
If the system stores connection point identification information for branching and merging points, then the vehicle can automatically navigate route changes, but the system requires complex infrastructure for managing these points
Solution Approach 1:
The patent replaces complex mechanical infrastructure for route changes with an information-based system. Instead of physically reconfiguring magnetic markers or adding complex mechanical switching mechanisms, the system uses electronic storage and transmission of connection point identification information. The control server manages routing data, and the vehicle's recognition system automatically processes this information, substituting mechanical complexity with information processing simplicity.

AI summary
In an operation system (1) for a bus (5) including a connection point database which stores identification information of a magnetic marker (10) positioned so as to correspond to a connection point (13) between a dedicated lane (111) having magnetic markers (10) laid thereon and a general lane (112), the connection point (13) is set so as to correspond to the magnetic marker (10) according to identification information stored in a connection point database, thereby allowing flexibility in changing a route to be improved in the operation system which causes a vehicle to operate along a route defined in advance.
