Movable Spoiler Structure for Aerodynamic Flow Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spoiler structures lack the ability to increase the surface area of the rear spoiler and improve flow adjustment effects, limiting their aerodynamic performance.
Innovation Solution
A spoiler structure with a movable flow adjustment portion that moves from a front position to a rear position via an intermediate position, where the rear end is elevated at the intermediate position and lowered at the rear position, utilizing link mechanisms and a turn actuator to adjust its height and angle, thereby increasing the surface area and improving airflow management.

Engineering Contradiction Analysis
1Area of moving object
If a conventional fixed spoiler structure is used, then the structure is simple and reliable, but the surface area of the rear spoiler cannot be increased and flow adjustment effect is limited
Solution Approach 1:
The spoiler is designed as a movable flow adjustment portion that can dynamically change its position and orientation. The spoiler moves from a front position to a rear position via an intermediate position, and the rear end moves upward then downward, allowing the surface area and flow adjustment effect to be optimized for different driving conditions while maintaining structural feasibility through controlled motion.
Solution Approach 2:
The spoiler structure utilizes multi-dimensional movement: it translates from front to rear position along the vehicle length, while the rear end simultaneously moves upward and downward to change the spoiler's angle and effective surface area. This multi-dimensional adjustment capability increases the functional surface area without proportionally increasing structural complexity.
2Reliability
If the spoiler surface area is increased to improve flow adjustment, then aerodynamic performance improves, but the structure becomes more complex
Solution Approach 1:
The spoiler employs dynamic movement mechanisms that allow a single structural element to achieve multiple aerodynamic functions. By moving the spoiler through different positions and orientations, the effective surface area and flow adjustment characteristics are optimized for various driving conditions, achieving reliable aerodynamic performance without requiring multiple separate structural components.
3Area of moving object
If the spoiler is made movable to increase surface area, then flow adjustment effect improves, but the control mechanism becomes more complex
Solution Approach 1:
The control mechanism is designed to exploit the natural dynamics of the spoiler structure. The spoiler moves from front to rear position while the rear end automatically traces an upward-then-downward path, creating different effective surface areas and flow adjustment effects at different positions. This dynamic behavior is controlled through a mechanism that leverages the spoiler's inherent motion characteristics rather than requiring complex independent control of multiple degrees of freedom.

AI summary
A spoiler structure includes a base portion that is attached to a vehicle body and a movable flow adjustment portion that is moved relative to the base portion from a front position on a vehicle front side to a rear position on a vehicle rear side via an intermediate position. A rear end of the movable flow adjustment portion is moved upward with movement of the movable flow adjustment portion from the front position to the intermediate position. The rear end of the movable flow adjustment portion is moved downward with movement of the movable flow adjustment portion from the intermediate position to the rear position. A height position of the rear end of the movable flow adjustment portion at the rear position is lower than a height position of the rear end of the movable flow adjustment portion at the front position.
