Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If aerodynamic devices are statically positioned, then manufacturing precision and structural simplicity are improved, but adaptability to varying vehicle conditions deteriorates
Solution Approach 1:
The aerodynamic device is transformed from a static structure to a dynamic one capable of movement. The device includes movable components that can be repositioned along the vehicle body, allowing it to adapt to different cornering radii, vehicle weights, and road conditions while maintaining aerodynamic performance across varying operating conditions.
Solution Approach 2:
The system changes the positional parameters of the aerodynamic device based on detected vehicle conditions. The controller adjusts the device position along the longitudinal and/or lateral axes according to parameters such as cornering radius, vehicle weight, and road conditions, optimizing performance for each specific operating scenario.
2Adaptability or versatility
If aerodynamic devices are made repositionable, then adaptability to varying vehicle conditions is improved, but device complexity and control system requirements worsen
Solution Approach 1:
The aerodynamic device system performs self-adjustment based on automatically detected vehicle conditions. The controller monitors parameters such as cornering radius, vehicle weight, and road conditions, then automatically repositions the aerodynamic device without requiring manual driver intervention, reducing the complexity of user interaction while maintaining high adaptability.
Solution Approach 2:
The system incorporates feedback mechanisms where sensors continuously monitor vehicle operating conditions and feed this information to the controller. The controller uses this feedback to determine optimal device positions, creating a closed-loop control system that automatically adapts to changing conditions while managing complexity through automated decision-making.
3Reliability
If aerodynamic devices are positioned for optimal performance in specific conditions, then performance in those conditions is improved, but performance across diverse conditions deteriorates
Solution Approach 1:
The aerodynamic device transitions from fixed positioning to dynamic repositioning capability. The device can move along the vehicle body to different locations optimized for current operating conditions, ensuring reliable performance across diverse scenarios including varying cornering radii, vehicle weights, and road conditions rather than being locked into a single suboptimal position.

AI summary
An aerodynamics control system for a vehicle may include a repositionable aerodynamic device disposed at a portion of the vehicle, a controller operably coupled to components or sensors of the vehicle to receive information including vehicle performance data and position information for the aerodynamic device, and a vehicle location sensor determining location information for the vehicle. The controller stores the vehicle performance data and the position information in association with the location information for each of a plurality of locations. Responsive to detecting an approach of the vehicle to one of the locations, the controller provides a control instruction to position the aerodynamic device based on recorded vehicle performance data and recorded position information associated with the one of the locations.
