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 spoiler structure incorporates the rear lamp housing and mounting mechanisms, allowing both aerodynamic functionality and lighting functions to coexist without interference. This merging eliminates the design challenges associated with separate mounting while maintaining aerodynamic efficiency.
Solution Approach 2:
The integrated spoiler-lamp assembly serves multiple functions simultaneously: it provides aerodynamic drag reduction, houses the rear lamp for illumination and signaling, and can incorporate additional features such as brake lights and reflectors. This multi-functionality resolves the contradiction by making the single structure serve both aerodynamic and lighting purposes.
2Object-affected harmful factors
If the air current adjustment module protrudes to improve vehicle traveling performance, then aerodynamic resistance is reduced, but the device complexity increases due to the drive module mechanism
Solution Approach 1:
The air current adjustment module is designed to be dynamically adjustable rather than fixed. The drive module enables the spoiler to move between retracted and extended positions, allowing optimization of aerodynamic performance under different driving conditions. This dynamic capability resolves the contradiction by providing adaptability that justifies the added mechanical complexity.
Solution Approach 2:
The drive module is integrated directly into the spoiler assembly, allowing the system to self-adjust its position based on operational needs. The mechanism includes self-contained actuators and control systems that eliminate the need for separate external control mechanisms, thereby reducing overall system complexity while maintaining the ability to reduce aerodynamic resistance.
