Variable Spoiler Lighting With Speed-Adaptive Tilt and Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing variable spoilers on vehicles can only adjust their tilting angle upward or downward and are not easily identifiable at night, which affects their aerodynamic performance and visibility.
Innovation Solution
A vehicular variable spoiler lighting apparatus that includes a rear lamp and a spoiler, both of which are movably positioned in the rear section of the vehicle. The apparatus features actuators to control the movement and tilting of the spoiler, and a control unit to manage the operation of the actuators and the rear lamp, which can protrude and tilt according to the vehicle's speed, enhancing visibility and aerodynamics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the spoiler is made to be identifiable at night by adding lighting, then visibility is improved, but device complexity increases
Solution Approach 1:
The patent combines the lighting function with the existing spoiler structure by integrating a light source unit into the spoiler body. The light source unit includes a light-emitting element and a lens that works together with the spoiler's transparent or translucent material to provide illumination without requiring a completely separate lighting system. This merging approach improves visibility while minimizing additional complexity.
Solution Approach 2:
The spoiler is designed to serve multiple functions: aerodynamic performance enhancement and nighttime visibility improvement. The light source unit is integrated into the spoiler structure, allowing the spoiler to function both as an aerodynamic device and as a lighting element. The control unit manages both the spoiler's positioning and the lighting operation, enabling multi-functionality without proportionally increasing complexity.
2Productivity
If the rear lamp and spoiler are made movable to adjust position and tilting angle, then aerodynamic performance is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic adjustability of the rear lamp and spoiler through actuators that can change their position and tilting angle according to vehicle speed. The control unit receives speed signals and automatically adjusts the components to optimal positions for different driving conditions. This dynamic capability improves aerodynamic performance across various speeds while using automated control to minimize manual intervention complexity.
Solution Approach 2:
The system operates autonomously by receiving vehicle speed signals and automatically controlling the actuators to position the rear lamp and spoiler optimally. The control unit manages the entire process without requiring manual input from the driver, allowing the system to self-adjust based on real-time speed conditions. This self-service approach improves aerodynamic performance while keeping the control interface simple.
