Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous vehicle system enhances its sensor data analysis and real-time decision-making capabilities to identify and respond to risks more effectively, then the safety and reliability of vehicle operation is improved, but the device complexity and computational requirements increase
Solution Approach 1:
The risk processing system is divided into distinct functional modules: sensor signal reception, risk identification, autonomous capability modification, and operation updating. This segmentation allows each module to specialize in specific tasks, improving overall reliability while managing complexity through modular architecture.
Solution Approach 2:
The system performs preliminary risk identification and analysis before actual hazardous events occur. By continuously analyzing sensor signals and predicting potential risks in advance, the system can prepare appropriate responses, improving safety without requiring overly complex real-time reaction mechanisms.
2Measurement precision
If the vehicle continuously monitors and analyzes sensor signals to identify multiple types of risks including pedestrian collisions, adverse weather, and complex driving scenarios, then the measurement precision and detection capability is improved, but the loss of processing time and computational resources increases
Solution Approach 1:
The system implements continuous feedback loops where sensor signals are constantly analyzed, risk assessments are updated in real-time, and autonomous capabilities are dynamically adjusted. This feedback mechanism enables precise risk identification while optimizing processing efficiency through iterative refinement rather than exhaustive analysis.
Solution Approach 2:
The system dynamically adjusts analysis parameters and processing depth based on the current operational context and detected risk levels. When risks are low, processing is streamlined; when risks are detected, analysis precision is enhanced, balancing measurement accuracy with processing time requirements.
3Adaptability or versatility
If the autonomous driving capability is frequently modified in response to identified risks to ensure safe operation, then the adaptability and responsiveness of the vehicle is improved, but the stability of vehicle control and operation may deteriorate
Solution Approach 1:
The autonomous driving capability is designed to be dynamically adjustable based on risk assessments. The system modifies control parameters and driving behaviors in response to identified risks while maintaining overall system stability through controlled adaptation rather than abrupt changes.
Solution Approach 2:
Continuous feedback monitoring ensures that modifications to autonomous capabilities are made only when necessary and are reverted or adjusted when risks are mitigated. This feedback-controlled adaptation maintains both responsiveness to hazards and stability of overall vehicle operation.
