Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traffic information is gathered from multiple heterogeneous information sources, then the quantity of traffic information is increased, but the consistency and reliability of the information deteriorates due to format variations, spatial, temporal, and semantic inconsistencies
Solution Approach 1:
The patent segments the traffic information processing into distinct modules: a format unifying device that handles format standardization, and a traffic information integrating device that processes spatial, temporal, and semantic inconsistencies. This segmentation allows each module to specialize in resolving specific types of inconsistencies while maintaining the benefits of multi-source data collection.
Solution Approach 2:
The patent introduces intermediary processing devices that act as mediators between heterogeneous information sources and the final integrated output. The format unifying device serves as an intermediary that standardizes data from different sources, while the integrating device further mediates to resolve conflicts and ensure consistency across spatial, temporal, and semantic dimensions.
2Device complexity
If simple combination of heterogeneous traffic information is performed, then the device complexity is reduced, but the accuracy and completeness of integrated traffic information deteriorates
Solution Approach 1:
The patent divides the processing system into specialized segments: a format unifying device for standardization and a traffic information integrating device for consistency resolution. This segmentation achieves high accuracy through dedicated processing for each type of inconsistency while maintaining reasonable device complexity through modular design.
3Loss of time
If traffic information from multiple sources is integrated without format unification, then the processing time is reduced, but the semantic consistency and reliability of the integrated information deteriorates
Solution Approach 1:
The patent applies preliminary action by performing format unification in advance through the format unifying device before the main integration process. This preliminary standardization reduces the complexity of subsequent semantic consistency processing and enables faster integration while maintaining high reliability, as the data is already standardized when it reaches the integrating device.
