Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional variable spoilers on vehicles lack visibility at night and struggle to adjust their position and direction effectively, impacting aerodynamic performance and visual communication.
Innovation Solution
A variable spoiler lighting apparatus with a rear lamp and spoiler that move and tilt based on driving modes, controlled by actuators and a controller, providing external visibility through light patterns and adjusting to minimize air resistance and enhance aerodynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional variable spoilers are used, then the spoiler can adjust vertical tilting angle, but the visibility of spoiler position and direction variation is poor especially at night
Solution Approach 1:
The patent combines the spoiler assembly with the rear lamp assembly into an integrated unit. The rear lamp is mounted on the spoiler, and both are controlled by the same actuators (first actuator for horizontal movement, second actuator for vertical tilting). This merging eliminates the need for separate lighting components while achieving the goal of improved visibility through the lamp's illumination.
Solution Approach 2:
The rear lamp serves dual functions: it provides illumination for visibility and acts as part of the spoiler assembly that adjusts position and angle. The same actuators control both the lighting function and the aerodynamic function, making the system multi-functional and reducing overall complexity.
2Loss of energy
If the rear lamp protrudes toward the rear of the vehicle, then aerodynamic performance is improved by minimizing air resistance, but the device complexity increases due to movable mounting mechanism
Solution Approach 1:
The rear lamp and spoiler are merged into a single integrated assembly that moves together as one unit. The rack and pinion mechanism controls the horizontal position of both components simultaneously, eliminating the need for separate mounting mechanisms and reducing overall system complexity while achieving aerodynamic benefits.
Solution Approach 2:
The movable mounting mechanism serves dual purposes: it positions the rear lamp for optimal lighting and simultaneously adjusts the spoiler position for aerodynamic efficiency. This multi-functionality reduces the need for additional components and simplifies the overall system.
3Loss of energy
If the spoiler tilts depending on driving mode, then aerodynamic performance is enhanced, but the difficulty of detecting and measuring spoiler variation increases
Solution Approach 1:
The spoiler position detection is merged with the rear lamp assembly. Since the lamp is mounted on the spoiler and moves with it, the lamp's position and illumination naturally indicate the spoiler's position and orientation, making detection easier without requiring separate sensors or measurement systems.
Solution Approach 2:
The rear lamp provides visual indication of the spoiler's position and state through its illumination. Different lighting patterns or intensities can indicate different driving modes and spoiler positions, making the system's state easily detectable by drivers and observers without complex measurement systems.
