Solution Overview
Problem
Conventional variable spoilers are difficult to identify from the outside, especially at night, and do not effectively enhance aerodynamic performance or provide visual information to drivers and pedestrians.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a conventional variable spoiler is used, then aerodynamic performance can be improved through tilting, but visual information is not provided to drivers and pedestrians especially at night
Solution Approach 1:
The patent combines the spoiler and rear lamp into a single integrated assembly where the lamp is mounted on the spoiler structure. This merging allows the spoiler to serve dual functions: aerodynamic control through tilting and visual information provision through the lamp's light patterns and movement, thereby resolving the contradiction between providing visual information and maintaining device simplicity
Solution Approach 2:
The integrated spoiler-lamp assembly performs multiple functions simultaneously: it provides aerodynamic benefits through variable tilting, communicates vehicle status through light patterns, and enhances visibility for pedestrians and other drivers. This multi-functionality addresses the information loss problem without requiring separate dedicated components
2Loss of energy
If the rear lamp and spoiler are integrated and movable, then aerodynamic performance is enhanced, but the device complexity increases
Solution Approach 1:
By merging the rear lamp and spoiler into a single movable assembly, the patent reduces the number of separate components and their associated mounting structures. The shared support structure and actuation mechanism for the integrated assembly minimize the overall complexity while maximizing aerodynamic benefits through coordinated movement of both components
Solution Approach 2:
The integrated assembly serves multiple purposes: it reduces air resistance through optimized aerodynamic shaping and variable positioning, while simultaneously providing visual communication functions. This multi-functionality justifies the increased complexity by delivering multiple benefits from a single system rather than requiring separate components for each function
3Loss of information
If the spoiler tilts at variable angles, then aerodynamic performance is optimized, but it becomes difficult to identify the spoiler's variable state from outside the vehicle
Solution Approach 1:
The patent uses the rear lamp to emit different light patterns that correspond to different spoiler tilting states. By changing the light pattern (color, intensity, or arrangement), the system visually communicates the spoiler's current angle and operational state to observers outside the vehicle, thereby resolving the contradiction between variable angle adjustment and state visibility
Solution Approach 2:
The integrated system provides visual feedback through the rear lamp that reflects the spoiler's current position and operational state. This feedback mechanism allows external observers to understand the spoiler's variable state without directly observing the mechanical tilting action, thus maintaining adaptability while improving state identifiability
