Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terrain classification and warning systems are implemented, then driver safety and vehicle protection are improved, but device complexity increases
Solution Approach 1:
The system performs preliminary classification of terrain unevenness before the vehicle encounters hazardous conditions. Sensors detect and classify terrain features ahead of time, allowing the system to issue warnings and suggest trajectory adjustments before the driver faces critical situations, thereby improving safety without requiring complex real-time intervention systems
Solution Approach 2:
The patent introduces an intermediary classification system that processes sensor data and translates it into driver-friendly warnings and trajectory suggestions. This intermediary layer between raw sensor data and driver decision-making simplifies the overall system architecture while maintaining high reliability through systematic terrain assessment
2Measurement precision
If multiple sensors are used for terrain detection, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system merges data from multiple sensor types (cameras, LIDAR, radar) into a unified terrain classification framework. By combining these sensors and processing their data through a single classification algorithm, the system achieves high measurement precision while avoiding the complexity of multiple independent detection systems
Solution Approach 2:
The classification system is designed to handle multiple sensor types and various terrain features through a single multi-functional algorithm. This universal approach allows the system to process data from different sensor modalities and classify diverse terrain unevenness types without requiring separate specialized systems for each function
