Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple camera devices are installed on the road to monitor vehicles, then vehicle detection capability is improved, but construction complexity and cost increase significantly
Solution Approach 1:
The patent uses image recognition technology to create a virtual model of the vehicle and its driving characteristics, replacing the need for physical camera installations. The system captures images using the vehicle's own camera or existing infrastructure cameras, then processes these images to extract driving behavior data, eliminating the need for extensive physical monitoring infrastructure.
Solution Approach 2:
The patent replaces the mechanical system of multiple physical camera devices with an information processing system that uses image recognition algorithms. Instead of relying on physical infrastructure to track vehicles, the system processes image data to identify and analyze driving characteristics, substituting mechanical monitoring with computational analysis.
2Ease of operation
If driving information is collected sporadically to evaluate driver behavior, then data collection simplicity is maintained, but determination accuracy deteriorates
Solution Approach 1:
The patent continuously collects and analyzes driving information by processing image data over extended periods. The system accumulates driving characteristic data through continuous image capture and analysis, transforming sporadic data points into a continuous record of driver behavior that enables accurate long-term evaluation of driving patterns.
Solution Approach 2:
The patent pre-establishes a database of driving characteristics by continuously collecting and storing driving behavior data before evaluation is needed. This preliminary data accumulation creates a comprehensive baseline that enables accurate determination of driver behavior patterns when evaluation is required, rather than attempting to assess behavior from limited sporadic observations.
3Area of stationary object
If camera devices are installed on specific roads to monitor driving, then monitoring coverage is improved for those areas, but ability to trace individual vehicles across different locations deteriorates
Solution Approach 1:
The patent creates a universal driving characteristic database that can identify and track individual vehicles across different locations and road segments. By extracting unique driving patterns from image data, the system enables a single monitoring point to contribute to the tracking of vehicles throughout the entire network, making the monitoring system versatile rather than location-specific.
Solution Approach 2:
The patent introduces a central database of driving characteristics as an intermediary that connects different monitoring points. This database stores unique driving pattern identifiers that allow vehicles to be recognized and tracked across multiple locations without requiring direct communication between camera systems, enabling seamless cross-location tracing through the intermediary database.
