Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a spoiler is mounted within the vehicle body to reduce aerodynamic resistance, then aerodynamic performance is improved, but the design becomes challenging due to interference with the rear lamp
Solution Approach 1:
The patent combines the spoiler and rear lamp into a single integrated assembly. The lamp is positioned within the spoiler structure, allowing both aerodynamic functionality and lighting functionality to coexist without interference. This merging eliminates the design conflict between mounting the spoiler within the vehicle body and accommodating the rear lamp.
Solution Approach 2:
The integrated spoiler-lamp assembly serves multiple functions simultaneously: it acts as both an aerodynamic device (spoiler) and a lighting device (rear lamp). This multi-functionality allows the single component to fulfill both aerodynamic performance requirements and lighting requirements, resolving the design challenge.
2Object-affected harmful factors
If the air current adjustment module protrudes to improve vehicle traveling performance, then aerodynamic performance is improved, but the device complexity increases due to the drive module mechanism
Solution Approach 1:
The air current adjustment module is designed to be movable rather than fixed. The drive module enables the spoiler to dynamically adjust its position (protrude or retract) based on driving conditions. This dynamic capability allows optimization of aerodynamic performance while the system can adapt to different operational requirements.
Solution Approach 2:
The integrated design allows the spoiler structure to serve its own mounting and support functions, eliminating the need for separate complex mounting mechanisms. The lamp assembly is self-contained within the spoiler structure, reducing overall device complexity despite the added actuation capability.
