Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles with short front overhangs and strong sweeps experience inadequate airflow deflection between the front and side areas, leading to unfavorable pressure conditions and increased air resistance, particularly affecting the front wheel housings.
Innovation Solution
An air guiding device with an extendable air guiding element that forms a flow channel with a covering element behind it, deflecting airflow and creating a turbulence-free passage over the wheelhouse, optimizing aerodynamics by generating streamlines parallel to the wheel flanks and providing an air gap for optimal airflow over the wheel housings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air guide element is extended to improve airflow deflection, then aerodynamic performance is improved, but device complexity increases
Solution Approach 1:
The air guide element is designed to be movable between retracted and extended positions, allowing the system to adapt its aerodynamic characteristics dynamically. This dynamic configuration enables optimized airflow deflection when extended while maintaining a streamlined profile when retracted, resolving the contradiction between aerodynamic performance and device simplicity.
Solution Approach 2:
The air guide element is divided into multiple segments or sections that can move independently or in coordination. This segmentation allows for refined control of airflow patterns while maintaining structural feasibility, addressing both the aerodynamic performance requirement and the structural complexity constraint.
2Reliability
If the air guide element is extended to deflect airflow, then airflow deflection is improved, but the vehicle front appearance is affected
Solution Approach 1:
The air guide element transitions between retracted and extended states based on driving conditions. When retracted, it maintains a clean vehicle front appearance; when extended, it provides optimized airflow deflection. This dynamic behavior resolves the contradiction between aesthetic appearance and aerodynamic functionality.
3Reliability
If the air guide element is made larger to improve airflow control, then airflow control is improved, but device complexity increases
Solution Approach 1:
The air guide element utilizes the vertical dimension by extending from the lower portion of the vehicle front upward. This vertical orientation provides effective airflow control without requiring excessive horizontal width or complex lateral structures, thereby improving airflow control while limiting device complexity.
