Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous vehicle uses sensors and machine learning models to classify behavioral characteristics of neighboring vehicles, then the safety and adaptability of autonomous driving is improved, but the device complexity and computational requirements increase
Solution Approach 1:
The system segments the complex task of autonomous driving by classifying neighboring vehicles into distinct behavioral categories (aggressive, defensive, neutral) based on observed characteristics. This segmentation allows the autonomous vehicle to apply different driving strategies for each category, simplifying the overall decision-making process while maintaining high safety standards through targeted analysis of specific behavioral patterns.
Solution Approach 2:
The system changes the parameter of vehicle behavior classification from raw sensor data to categorized behavioral characteristics. By transforming continuous sensor observations into discrete behavioral categories (aggressive, defensive, neutral), the system reduces computational complexity while preserving essential safety information needed for reliable autonomous driving.
2Adaptability or versatility
If the autonomous vehicle continuously monitors and classifies neighboring vehicles, then the adaptability to mixed traffic conditions is improved, but the loss of time for data processing increases
Solution Approach 1:
The system performs preliminary classification of neighboring vehicles into behavioral categories based on initial sensor observations. By pre-classifying vehicles before critical driving decisions are required, the system reduces real-time processing time while maintaining adaptability to mixed traffic conditions. The classification framework is established in advance, allowing rapid response to varying traffic scenarios.
Solution Approach 2:
The system implements continuous feedback loops where classification results are used to adjust driving behavior, and new sensor data refines future classifications. This feedback mechanism enables the system to adapt to changing traffic conditions efficiently, processing only relevant updates rather than continuously analyzing all raw sensor data, thereby reducing time loss while maintaining high adaptability.
3Speed
If the autonomous vehicle updates its driving plan based on classified behavioral characteristics, then the responsiveness to neighboring vehicles is improved, but the device complexity increases
Solution Approach 1:
The system applies local quality by implementing different driving strategies tailored to each classified behavioral category. Instead of using a single complex control algorithm for all situations, the system selects and applies appropriate local strategies (e.g., more cautious approach to aggressive vehicles, more assertive behavior toward defensive vehicles). This reduces overall system complexity by using simpler, targeted control logic for each specific scenario while maintaining high responsiveness.
Solution Approach 2:
The driving plan is dynamically updated based on classified behavioral characteristics of neighboring vehicles. The system transitions between different driving modes and strategies in real-time according to the classified behavior categories, enabling responsive adaptation without requiring a completely complex re-planning algorithm. The dynamic nature of the system allows it to switch between pre-defined strategic responses based on classification results.
