Solution Overview
Problem
Existing air-guiding devices for vehicles face challenges in reliably and efficiently displacing auxiliary air-guiding elements relative to the main air-guiding element without structural obstruction, requiring a simpler and more compact design.
Innovation Solution
The air-guiding device employs a guide unit with slide and guide elements allowing vertical and horizontal displacement of auxiliary air-guiding elements, utilizing a common drive mechanism with spindles and flexible shafts, and self-locking mechanisms to ensure reliable and unobstructed movement, while maintaining a compact structure and sealing against environmental elements.

Engineering Contradiction Analysis
1Reliability
If auxiliary air-guiding elements are displaced relative to the main air-guiding element using conventional guide mechanisms, then the auxiliary elements can move between retracted and deployed positions, but the structure becomes complex and prone to blocking
Solution Approach 1:
The guide mechanism is segmented into multiple independent guide elements (first guide element, second guide element, third guide element) that each handle specific displacement directions. This segmentation allows each element to perform a specialized function, reducing overall structural complexity while improving reliability through distributed guidance functions.
Solution Approach 2:
The auxiliary air-guiding elements are nested within the main air-guiding element when in the retracted position. The guide elements are arranged such that they provide guidance within the confined space of the main element, allowing compact storage while enabling full displacement when deployed.
2Reliability
If multiple guide elements are used to displace auxiliary air-guiding elements in two directions, then blocking is prevented, but the device occupies more structural space
Solution Approach 1:
The guide elements utilize three-dimensional spatial arrangement to achieve guidance in multiple directions. The first guide element guides in a first direction, the second guide element guides in a second direction transverse to the first, and the third guide element guides in a vertical direction. This multi-dimensional arrangement prevents blocking while maintaining compact overall dimensions.
Solution Approach 2:
The guide elements are arranged to provide dynamic guidance that adapts to the displacement position of the auxiliary air-guiding elements. The elements work together to ensure smooth movement throughout the entire range of motion, preventing blocking at any position while optimizing space utilization.

AI summary
An air-guiding device (12) is arranged in a rear-end region of a vehicle and has a central main air-guiding element (13) that is displaceable from a retracted rest position into a deployed operating position. Lateral auxiliary air-guiding elements (14, 15) are adjustable substantially linearly relative to the main air-guiding element (13) in a direction transverse to the longitudinal direction of the vehicle to be transferred from a rest position, in which they are retracted into the main air-guiding element (13), into an operating position, in which they are deployed out of the main air-guiding element (13). Each auxiliary air-guiding element is movable along a guide unit (22) in the main air-guiding element (13) and is guided in the guide unit (22) in a first direction by at least one slide element (26) and in a second direction by at least one guide pin (27).
