Motor Vehicle Air Scoop Rotation Axis Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing front-end designs for motor vehicles face challenges in accessing motor vehicle body connecting points, particularly screw connection points, especially when a large air scoop is pre-installed, due to the conventional axis of rotation between the central and lateral air-guiding elements, which hinders efficient installation and requires additional fastening elements.
Innovation Solution
The air scoop is designed to rotate between pre-installation and installation positions along an axis formed between the lateral air-guiding element and itself, allowing improved accessibility to connecting points without additional fasteners, and features a rear wall without openings for unobstructed air transfer between central and lateral air-guiding elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the air scoop is pre-installed with a conventional axis of rotation between central and lateral air-guiding elements, then the air scoop can be transferred between positions, but accessibility to motor vehicle body connecting points is hindered
Solution Approach 1:
The patent inverts the conventional axis of rotation configuration by placing it between the lateral air-guiding element and the air scoop rather than between the central air-guiding element and the air scoop. This inversion allows the air scoop to rotate without interfering with accessibility to the motor vehicle body connecting points, thereby improving ease of operation while maintaining a relatively simple device structure.
2Reliability
If additional fastening elements are used to secure the air scoop, then the air scoop can be firmly attached, but the device complexity and installation requirements increase
Solution Approach 1:
The air scoop is designed to be held automatically by the lateral air-guiding element through the rotated position, eliminating the need for additional fastening elements. The geometric relationship between the air scoop and lateral air-guiding element creates a self-locking mechanism that provides reliable attachment without increasing device complexity or requiring extra fastening components.
3Quantity of substance
If the rear wall of the air scoop has openings, then air can pass through, but the air transfer between air-guiding elements becomes obstructed
Solution Approach 1:
The patent removes openings from the rear wall of the air scoop, extracting the air passage function from that specific location. Instead, air is guided through dedicated air-guiding passages integrated into the air scoop structure, which allows the rear wall to remain solid and unobstructed while still enabling effective air transfer between the central and lateral air-guiding elements.

AI summary
A front-end part of a motor vehicle has a front panel with air inlet openings in a central region and lateral regions. A central air-guiding element (14) is positioned behind a central air inlet opening in the front panel and a lateral air-guiding element (15) is positioned behind at least one lateral air inlet opening in the front panel. An air scoop (18) is arranged between the central air-guiding element (14) and at least one lateral air-guiding element (15). The air scoop (18) can be moved between a pre-installation position where the air scoop is spaced from the central air-guiding element and an installation position where the air scoop is placed against or connected to the central air-guiding element.
