Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional traffic monitoring systems are used to accurately determine driving behavior and road conditions, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses statistical models and comparison algorithms as intermediaries to evaluate driving behavior. Instead of directly measuring complex driving patterns, the system compares vehicle parameters against statistical norms derived from multiple vehicles, simplifying the measurement process while maintaining accuracy.
Solution Approach 2:
The system creates virtual copies of driving scenarios by collecting data from multiple vehicles and generating statistical representations. These copied data sets are then used for comparison and evaluation, reducing the need for complex direct measurement systems in each individual vehicle.
2Measurement precision
If expensive and invasive monitoring systems are deployed, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system enables vehicles to self-evaluate their driving behavior by automatically collecting their own operational data and comparing it against statistical norms. This self-service approach eliminates the need for external monitoring infrastructure, making deployment easier while maintaining measurement precision.
Solution Approach 2:
The patent creates a universal evaluation system that can be applied across multiple vehicles and different driving conditions. By establishing general statistical models that work across diverse scenarios, the system achieves broad applicability without requiring vehicle-specific customization, enhancing ease of operation.
3Measurement precision
If data is collected from multiple vehicles for statistical analysis, then measurement precision is improved, but loss of information increases due to data processing requirements
Solution Approach 1:
The system extracts only the essential parameters needed for driving behavior evaluation from the collected vehicle data, rather than processing all available information. By identifying and extracting key metrics such as speed, acceleration, and positioning data, the system maintains measurement precision while minimizing information loss during processing.
Solution Approach 2:
The patent transforms raw vehicle operational data into standardized statistical parameters that can be efficiently processed and compared. By changing the form of the data from raw sensor readings to normalized statistical measures, the system reduces processing complexity and minimizes information loss while maintaining evaluation accuracy.
