Variable Spoiler Lighting for Aerodynamics and Night Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular variable spoilers can only adjust their tilting angle upward or downward and are not identifiable at night from outside the vehicle, which limits their aerodynamic performance and visibility.
Innovation Solution
A variable spoiler apparatus with a spoiler unit that can extend or tilt opposite to the vehicle's forward direction, equipped with a rear lamp that emits light opposite to the forward direction, and an actuator unit that controls the spoiler's movement and tilting angle, along with a control unit to manage these operations based on the vehicle's speed and mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a variable spoiler is designed to adjust only the tilting angle upward or downward, then the device complexity is reduced, but the aerodynamic performance is limited
Solution Approach 1:
The spoiler is divided into multiple independent segments that can move relative to each other. The first spoiler segment can extend backward, while the second spoiler segment can tilt independently, allowing complex aerodynamic adjustments without requiring a completely complex single-unit mechanism.
Solution Approach 2:
The spoiler transitions from a static or single-degree-of-freedom structure to a multi-degree-of-freedom dynamic structure. The first spoiler moves in the forward-backward direction while the second spoiler tilts upward or downward, creating dynamic adaptability for different driving conditions.
2Ease of manufacture
If the spoiler structure is simplified for ease of manufacture, then the manufacturing cost is reduced, but the visibility and identifiability at night is worsened
Solution Approach 1:
The lighting function is merged with the spoiler structure itself. The rear lamp is integrated into the spoiler assembly, combining the aerodynamic component with the lighting component into a single manufactured unit, reducing overall system complexity while improving nighttime visibility.
Solution Approach 2:
The spoiler assembly serves multiple functions: aerodynamic control through the variable spoiler segments and visual signaling through the integrated rear lamp. This multi-functionality is achieved within a single manufactured assembly rather than separate components.
3Illumination intensity
If the spoiler is made identifiable at night with lighting, then the visibility is improved, but the device complexity increases
Solution Approach 1:
The lighting system is merged with the spoiler structure, with the rear lamp integrated directly into the spoiler assembly. This integration reduces the overall device complexity compared to having separate lighting and spoiler systems.
Solution Approach 2:
The spoiler structure itself serves the lighting function through the integrated rear lamp, eliminating the need for additional separate lighting components and reducing overall system complexity.
