Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a rear spoiler with adjustable aerodynamic profiles is provided to increase downforce, then the downforce is improved, but the running resistance increases
Solution Approach 1:
The aerodynamic profiles are made dynamically adjustable through a mechanical transmission system that allows real-time modification of the profile angles. This enables the rear spoiler to adapt its aerodynamic characteristics based on driving conditions, optimizing the balance between downforce generation and running resistance minimization
2Adaptability or versatility
If complex actuation systems are used to adjust aerodynamic profiles, then the aerodynamic efficiency is improved, but the device complexity and weight increase
Solution Approach 1:
Multiple adjustment functions for different aerodynamic profiles are merged into a single mechanical transmission system. This integrated approach allows simultaneous adjustment of multiple profiles through one actuator, reducing the number of separate actuation mechanisms while maintaining high aerodynamic adaptability and efficiency
Solution Approach 2:
The mechanical transmission system is designed with multi-functionality to perform multiple adjustment tasks. A single transmission mechanism can adjust different aerodynamic profiles at different positions, replacing what would traditionally require multiple separate actuation systems, thereby reducing overall device complexity and weight
