Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vehicle divides the driving path into multiple courses and displays fuel efficiency information for each course, then the fuel efficiency information accuracy is improved, but the device complexity increases
Solution Approach 1:
The driving path is divided into multiple courses based on weight change events. Each course represents a segment with specific fuel efficiency characteristics. This segmentation allows the system to provide accurate fuel efficiency information for each segment while managing complexity through modular data structure and processing.
2Measurement precision
If the vehicle tracks weight changes and driving distance to calculate fuel efficiency, then the fuel efficiency measurement precision is improved, but the device complexity increases
Solution Approach 1:
The weight detector serves multiple functions: detecting load state changes, determining course boundaries, and triggering fuel efficiency calculations. The controller integrates multiple detection functions (weight, speed, distance) into a unified processing system that manages complexity through centralized control logic.
3Loss of information
If the vehicle provides detailed fuel efficiency information for each course, then the information completeness is improved, but the information processing complexity increases
Solution Approach 1:
Fuel efficiency information is segmented by course, with each course having its own fuel efficiency metric. The system stores and processes data in a structured format that associates fuel efficiency values with specific course identifiers, enabling complete information delivery through organized data management.
