Rear Air Guiding Device Mounting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle air guiding devices, such as rear wings or spoilers, are difficult to mount, install, and adjust with minimal structural complexity, requiring multiple screws and complex positioning mechanisms.
Innovation Solution
A mechanism with hooking-in and connecting means allows the air guiding device to be easily plugged and pivoted into place, using adjustable spacers for alignment and a pin-and-socket principle for secure attachment, reducing the need for visible fastening elements and enabling easy adjustment and extension/retraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws and complex positioning mechanisms are used to mount the air guiding device, then the fastening reliability is improved, but the device complexity and difficulty of installation increase
Solution Approach 1:
The mounting mechanism is divided into two independent functional parts: hooking-in means for initial attachment and connecting means for final fastening. This segmentation allows each component to be optimized for its specific function, simplifying the overall structure while maintaining reliability through the coordinated action of both parts.
Solution Approach 2:
The hooking-in means enables preliminary attachment of the air guiding device to the mechanism before final connection. This preliminary action allows for easy positioning and alignment, after which the connecting means secures the device firmly, reducing installation complexity while ensuring reliable fastening.
2Strength
If multiple screws and positioning mechanisms are used, then the fastening strength is improved, but the installation time increases
Solution Approach 1:
The hooking-in means allows the air guiding device to be quickly attached in a preliminary manner without requiring multiple screws to be precisely positioned. This preliminary attachment enables rapid installation initially, followed by the connecting means which provides strong fastening with minimal additional time required.
3Reliability
If visible fastening elements are used to secure the air guiding device, then the connection reliability is improved, but the aesthetic appearance deteriorates
Solution Approach 1:
The visible fastening elements (screws) are extracted from the visible exterior of the air guiding device and placed on the bearing plate side. The hooking-in means and connecting means are arranged so that the fastening components are hidden from external view, maintaining aesthetic appearance while preserving connection reliability through the mechanical interlocking of the hooking-in means with the bearing plate.
4Manufacturing precision
If a fixed mounting structure is used, then the manufacturing precision is improved, but the adjustability decreases
Solution Approach 1:
The mounting mechanism transitions from a fixed structure to a dynamic, adjustable system. The hooking-in means allows the air guiding device to be initially attached in a predetermined precise position, while the connecting means enables subsequent adjustment of the angular position. This dynamic capability allows the device to be mounted with manufacturing precision initially, then adjusted to different angles as needed.

AI summary
A motor vehicle (1) has a rear air guiding device (2) and a mechanism (3) for receiving and fastening the air guiding device (2). The mechanism (3) has a pin (6) in one end region for hooking-in at a socket (14) in the air guiding device (2). Thus the air guiding device (2) can be pivoted relative to the mechanism (3). A connector (18) connects the air guiding device (2) and the mechanism (3) at a position spaced from the pin (6) and the socket (14). An adjustable spacer (8, 10) is between the air guiding device (2) and the mechanism (3) near the connector (18).
