Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If aerodynamic performance improvement apparatuses are mounted to regulate air current, then aerodynamic performance is improved, but the apparatus may collide with obstacles causing damage
Solution Approach 1:
The air current regulator is designed with extendable and retractable components that can dynamically adjust their position. The regulator extends when aerodynamic performance improvement is needed and retracts when obstacles are detected, allowing the system to adapt to different operational conditions and avoid collisions while maintaining aerodynamic benefits
2Reliability
If aerodynamic performance improvement apparatuses are mounted to regulate air current, then aerodynamic performance is improved, but the apparatus is in the way of air current causing decreased traveling stability when strong wind blows
Solution Approach 1:
The system incorporates wind sensors and control mechanisms that detect strong wind conditions. When strong wind is detected, the air current regulator automatically adjusts its position or retracts to minimize interference with natural air flow, thereby maintaining vehicle stability while still providing aerodynamic performance improvement under normal conditions
3Reliability
If air current regulator extends out of rear section to regulate air current, then vortex dissipation and aerodynamic performance are improved, but the device complexity increases
Solution Approach 1:
The air current regulator is divided into multiple independent segments or components, including extendable fins and retractable elements. This segmentation allows each component to be controlled independently, simplifying the overall control mechanism while maintaining effective vortex dissipation capability through coordinated operation of the segments
