Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed wind wing is installed on the motorcycle, then the safety and stability at high speeds are improved, but the downforce generation efficiency varies at different speeds
Solution Approach 1:
The wind wing angle is made adjustable rather than fixed. The adjustment mechanism allows the wind wing to change its angle dynamically based on vehicle speed, transitioning from a static structure to a dynamic one that adapts to varying operating conditions.
Solution Approach 2:
The angle parameter of the wind wing is changed according to vehicle speed. At higher speeds, the wind wing angle is adjusted to generate more downforce, while at lower speeds, the angle is reduced to minimize drag, optimizing performance across different speed ranges.
2Force
If the wind wing angle is increased to generate more downforce at high speeds, then the stability is improved, but the wind resistance increases at low speeds
Solution Approach 1:
The system dynamically adjusts the wind wing angle based on real-time speed detection. At high speeds, the angle increases to maximize downforce for stability. At low speeds, the angle decreases to minimize wind resistance and energy loss, creating an optimal balance across different operating conditions.
Solution Approach 2:
A speed sensor provides feedback to the control unit about the vehicle's current speed. The control unit uses this feedback information to automatically adjust the wind wing angle through the adjustment mechanism, ensuring optimal downforce generation without excessive wind resistance at any given speed.
3Device complexity
If a single-blade wind wing is used, then the structure is simple, but the downforce generation efficiency is limited
Solution Approach 1:
The wind wing is divided into multiple blades instead of using a single large blade. Each blade can be independently adjusted and optimized. The multi-blade configuration allows the system to generate more downforce by utilizing the combined aerodynamic effects of multiple smaller surfaces working together.
Solution Approach 2:
Each blade is equipped with an independent adjustment mechanism that allows it to be positioned at optimal angles for maximum downforce generation. The dynamic adjustment capability enables the multi-blade structure to optimize its configuration based on real-time speed and aerodynamic conditions.
