Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If comprehensive sensor data is transmitted to provide complete driving information, then measurement precision and reliability are improved, but bandwidth consumption and data transmission volume increase
Solution Approach 1:
The system extracts and transmits only the specific driving information that is actually needed by the vehicle, rather than transmitting all sensor data. The processing unit identifies and extracts relevant information elements based on the vehicle's current context and requirements, filtering out unnecessary data to reduce transmission volume while maintaining information accuracy.
Solution Approach 2:
The system applies different data transmission qualities to different information types based on their importance and the vehicle's current needs. Critical safety-related information is transmitted with high precision and completeness, while less critical information is transmitted with reduced detail or only when relevant, creating a localized quality approach to data transmission.
2Ease of operation
If sensor configurations are fixed to simplify system operation, then ease of operation is improved, but adaptability to different driving scenarios deteriorates
Solution Approach 1:
The sensor configuration is made dynamic rather than fixed. The processing unit automatically adjusts sensor parameters such as field of view, sampling frequency, and data transmission intervals based on the vehicle's current driving context, road conditions, and information needs. This allows the system to adapt to different scenarios while maintaining simple operation through automated control.
Solution Approach 2:
The system implements feedback mechanisms where the processing unit continuously monitors driving conditions and vehicle information needs, then adjusts sensor configurations accordingly. The vehicle's autopilot system provides feedback about information requirements, and the processing unit uses this feedback to dynamically reconfigure sensors, creating a closed-loop adaptive system.
