Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a vertically oriented airflow is generated to improve traction, then driving characteristics are improved, but aerodynamic drag increases
Solution Approach 1:
The airflow guiding system employs adjustable flaps and movable channel members that can dynamically change the airflow direction from vertical to horizontal based on driving conditions. This dynamic adjustment allows the system to switch between generating downforce for traction and reducing aerodynamic drag, resolving the contradiction between these two opposing requirements.
Solution Approach 2:
The system changes the flow direction parameter of the airflow from vertical orientation (for traction) to horizontal orientation (for drag reduction). By varying this parameter based on predefined vehicle parameters, the system can optimize performance for different driving situations, eliminating the need to maintain a fixed vertical airflow configuration.
2Object-affected harmful factors
If external control surfaces such as spoilers or wings are used to reduce aerodynamic drag, then aerodynamic efficiency is improved, but device complexity increases
Solution Approach 1:
The patent combines the airflow control function with the existing vehicle body structure by integrating air channels and control surfaces into the vehicle's body panels. This merging eliminates the need for separate external spoilers or wings, reducing device complexity while maintaining aerodynamic control capabilities.
Solution Approach 2:
The air channel arrangement serves multiple functions: it guides airflow for drag reduction, generates downforce when needed, and can be adjusted based on various driving conditions. This multi-functionality replaces the need for multiple dedicated external control surfaces, simplifying the overall system.
3Force
If airflow direction is fixed vertically to generate downforce, then driving characteristics are improved, but adaptability to different driving situations deteriorates
Solution Approach 1:
The system incorporates adjustable flaps and movable channel members that can dynamically change airflow direction from vertical to horizontal based on real-time driving conditions. This dynamic capability allows the system to adapt to various situations such as high-speed cruising, cornering, or rainy conditions, greatly enhancing versatility while maintaining downforce generation when needed.
