Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple motors are used for deflection control in existing air outflow devices, then the air flow direction can be adjusted, but the device complexity and costs increase
Solution Approach 1:
The patent combines multiple deflection control functions into a single electric servomotor. The rotation ring with fins is rotated by this one motor to simultaneously control both vertical and horizontal air flow deflection, eliminating the need for multiple separate motors and reducing overall system complexity
Solution Approach 2:
The single electric servomotor performs multiple functions by rotating the rotation ring, which in turn controls fins that deflect air flow in multiple directions. This multi-functional approach allows one motor to replace what would traditionally require multiple motors, reducing complexity while maintaining full deflection control capability
2Ease of operation
If manual adjustments are required for air flow direction, then the device structure can be simpler, but the ease of operation and precision are reduced
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated electric servomotor system. The motor-driven rotation ring and slide guide mechanism automatically control fin positioning and air flow direction, eliminating the need for manual operation while providing precise and programmable control
Solution Approach 2:
The electric servomotor system automatically adjusts the air flow direction without requiring user intervention. The rotation ring rotates to position fins, and the slide guide automatically displaces fins to the correct positions, enabling the system to self-regulate air flow distribution based on programmed sequences
3Measurement precision
If fins are displaced by rotation ring rotation through slide guide, then precise control is achieved, but the device complexity increases
Solution Approach 1:
The slide guide acts as an intermediary mechanism between the rotation ring and the fins. It translates the rotational motion of the rotation ring into precise linear displacement of the fins along guided paths, enabling accurate fin positioning while maintaining a relatively simple mechanical structure
Solution Approach 2:
The slide guide mechanism transforms rotational motion in one dimension (rotation ring rotation) into linear displacement in another dimension (fin movement). This dimensional transformation allows precise control of fin positions through a straightforward mechanical linkage rather than complex multi-axis positioning

AI summary
An air outflow device for feeding tempered air for an interior of a motor vehicle includes an electric servomotor, a rotatably mounted rotation ring, and a fixed slide guide. The rotation ring has displaceable fins in an inner region of the rotation ring. A pin of the rotation ring engages with the slide guide and the pin is connected to the fins such that the fins are displaced by a rotation of the rotation ring.
