Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air guiding devices for vehicles do not efficiently adapt their transverse and longitudinal extensions during operation, limiting their ability to enhance rear axle output coefficient and aerodynamics.
Innovation Solution
The air guiding device features pivotable lateral additional air guiding elements coupled to a central main air guiding element, allowing simultaneous adjustment and extension of the device's transverse and longitudinal dimensions through a mechanical linkage system, enabling quick and simple adaptation of the device's shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the transverse extent of the air guiding device is increased using lateral additional air guiding elements, then the rear axle output coefficient is improved, but the device complexity increases due to separate adjustment mechanisms
Solution Approach 1:
The patent combines the adjustment of the central main air guiding element and the lateral additional air guiding elements into a single integrated mechanism. The coupling device mechanically links the actuating device to both the central and lateral elements, enabling simultaneous adjustment through one actuation source, thereby reducing overall system complexity while maintaining enhanced adaptability
Solution Approach 2:
The actuating device is designed with multi-functionality to control both the central main air guiding element and the lateral additional air guiding elements. This universal actuator performs multiple functions: it pivots the central element and simultaneously controls the pivoting of lateral elements, eliminating the need for separate adjustment mechanisms and reducing device complexity
2Ease of operation
If the lateral additional air guiding elements are adjusted after the central main air guiding element, then the adjustment sequence is simplified, but the adaptation time is increased
Solution Approach 1:
The coupling device merges the adjustment operations of the central and lateral air guiding elements into a single simultaneous action. When the actuating device moves, it directly pivots the central main air guiding element while simultaneously causing the lateral additional air guiding elements to pivot through the mechanical linkage, eliminating sequential adjustment delays
Solution Approach 2:
The mechanical coupling ensures continuous and simultaneous adjustment action across all air guiding elements. The coupling device maintains constant mechanical engagement with both the central and lateral elements throughout the adjustment process, ensuring that all components adapt continuously and simultaneously rather than in discrete sequential steps, thereby reducing total adaptation time

AI summary
The invention relates to an air guide device (13) for a vehicle, in particular for a passenger car, which is arranged in a rear area (10) of the vehicle and comprises at least one central main air guide element (14) which can be moved from a retracted rest position to an extended operating position, wherein lateral auxiliary air guide elements (15, 16) can be moved together with the main air guide element (14). According to the invention, the auxiliary air guide elements (15, 16) are pivotable relative to the main air guide element (14) about at least two pivot points fixed to the main air guide element and about at least two pivot points fixed to the auxiliary air guide element laterally next to the main air guide element (14) in order to move them from a retracted rest position to an extended operating position.
