Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the rectifying body is deployed on the front side of the front wheel to suppress air flow, then the aerodynamic performance is improved, but freezing around the rectifying body occurs in cold conditions
Solution Approach 1:
The heating mechanism changes the temperature parameter of the rectifying body and its periphery from cold conditions to above-freezing temperatures, preventing ice and snow accumulation while maintaining the deployed position for aerodynamic performance
Solution Approach 2:
The patent replaces mechanical clearing methods with a thermal field (heating mechanism) to melt freezing, providing a more effective and automated solution for removing ice and snow accumulation around the rectifying body
2Ease of operation
If the rectifying body is housed in the vehicle body, then the device is retracted, but freezing between the rectifying body and deployment hole peripheral surface occurs
Solution Approach 1:
The heating mechanism raises the temperature of the deployment hole peripheral surface and rectifying body interface, changing the thermal parameter to prevent freezing and enable smooth retraction of the rectifying body into the vehicle body
Solution Approach 2:
The heating mechanism acts as an intermediary thermal field between the rectifying body and deployment hole, facilitating the separation and retraction process by preventing direct freezing contact between these components
3Ease of operation
If ice and snow accumulate around the rectifying body, then operational resistance increases, but the heating mechanism requires additional energy consumption
Solution Approach 1:
The heating mechanism operates in advance or concurrently with deployment/retraction operations to prevent freezing before it significantly increases operational resistance, reducing the total energy required compared to clearing accumulated ice and snow after the fact
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively melts freezing around the rectifying body, reducing operational resistance and preventing damage, ensuring smooth operation and extending the lifespan of the device by maintaining clear pathways and reducing physical stress from ice accumulation.
Implementation Method 1
a heating mechanism that is operated to heat a periphery of the rectifying body
Implementation Method 2
the heating mechanism is operated to heat the rectifying body. Therefore, the periphery of the rectifying body can be heated
Implementation Method 3
the heating mechanism is operated to heat the covering member. Therefore, it is possible to heat a space between the rectifying body and the peripheral surface of the deployment hole

AI summary
In a rectifying device, an actuator is operated to rotate a deflector, Here, a heater on an inner peripheral surface of the deflector is operated to generate heat, so that a periphery of the deflector is heated. Therefore, freezing around the deflector can be melted.
