Solution Overview
Problem
Current automotive aerodynamic systems face challenges in managing airflow and reducing drag, lift, and instability at high speeds, particularly at the rear of vehicles, where turbulence and drag increase due to turbulent airflow and low-pressure zones.
Innovation Solution
An integrated lighting system with an adjustable aerodynamic element, such as a rear wing or spoiler, that includes a light source and a light-reflecting feature, allowing for controlled airflow management and downforce adjustment, while maintaining the orientation of the light beam along the vehicle's longitudinal axis, even as the aerodynamic element deploys or retracts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed aerodynamic element is used, then the light signal orientation remains stable, but the aerodynamic performance cannot be adjusted for different driving conditions
Solution Approach 1:
The aerodynamic element is made movable rather than fixed, allowing it to adjust its position between retracted and deployed states. This dynamic configuration enables the system to adapt aerodynamic performance to different driving conditions while the lighting system maintains functional consistency through active orientation control.
Solution Approach 2:
The lighting system incorporates active orientation control that responds to the aerodynamic element's position. Sensors detect the element's configuration and the lighting system adjusts accordingly to maintain proper signal orientation, creating a feedback loop that resolves the contradiction between adaptability and stability.
2Adaptability or versatility
If the aerodynamic element is made movable to adjust downforce, then aerodynamic performance improves, but the complexity of the system increases
Solution Approach 1:
The lighting system and aerodynamic element control are integrated into a unified system. The same actuation mechanism serves both the aerodynamic element and the lighting orientation, reducing overall system complexity despite the added functionality. The control system manages both functions through coordinated operation.
3Stability of the object's composition
If the aerodynamic element deploys to reduce drag and increase stability, then high-speed performance improves, but the light signal orientation may become misaligned
Solution Approach 1:
The lighting system uses feedback from sensors that detect the aerodynamic element's position to actively adjust light signal orientation. When the element deploys, the system receives feedback and reorients the lights accordingly, maintaining proper alignment and visibility throughout the deployment range.
Solution Approach 2:
The lighting system transitions from a static orientation to a dynamic one that actively adapts to the aerodynamic element's position. This dynamic adjustment ensures that light signals remain properly oriented and visible regardless of whether the aerodynamic element is retracted or deployed.

Function Achieved in This Case
The system effectively reduces aerodynamic drag and enhances high-speed stability by controlling airflow and downforce, while ensuring consistent visibility of light signals, such as taillights and turn signals, through the use of a light-reflecting feature that maintains beam orientation regardless of the aerodynamic element's position.
Implementation Method 1
a light-reflecting feature arranged on the aerodynamic-element body and having an orientation configured to reflect the at least one beam of light along the longitudinal axis in a direction away from the first vehicle body end
Implementation Method 2
a higher pressure zone created in front of the spoiler may help reduce lift on the vehicle body by creating a desired magnitude of downforce depending on the road speed of the vehicle
Implementation Method 3
Adding an active aerodynamic element, such as a spoiler, at the rear of the vehicle body may help to delay flow separation from the body
