Vehicle Air Guide Clip Mounting Acoustic Decoupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air guide devices for vehicles face challenges in noise reduction and component complexity due to the use of screws and metal inserts, which can lead to increased installation time and noise generation during operation.
Innovation Solution
The air guide device employs a clip connection between a plastic carrier part and metal or plastic installation brackets, utilizing spherical or joint-head-like anchoring elements and rubber or rubber-elastic attachment elements for acoustic decoupling, eliminating the need for screws and metal inserts, and featuring a kinematic link arrangement with an adjusting motor for displacement between retracted and deployed positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws and metal inserts are used for connection, then connection strength is improved, but noise generation increases and installation time increases
Solution Approach 1:
The patent introduces rubber or rubber-elastic attachment elements as intermediary components between the plastic carrier part and installation brackets. These elastic elements serve as mediators that provide both mechanical connection strength and acoustic decoupling, eliminating noise generation while maintaining secure attachment without screws or metal inserts
2Strength
If screws and metal inserts are used for connection, then connection strength is improved, but installation time increases
Solution Approach 1:
The patent extracts and eliminates screws, metal inserts, and complex fastening mechanisms from the connection system. By removing these time-consuming components and replacing them with simple clip connections using elastic elements, the installation process is dramatically simplified while maintaining adequate connection strength for the application
Solution Approach 2:
The rubber-elastic attachment elements are designed to self-secure the carrier part to the installation brackets through their elastic properties. The clips automatically engage and lock into position without requiring additional fastening steps, tools, or complex assembly procedures, enabling rapid installation
3Productivity
If clip connection with elastic elements is used, then installation time is reduced and noise is reduced, but connection strength may be compromised
Solution Approach 1:
The patent employs composite material construction by combining plastic carrier parts with rubber or rubber-elastic attachment elements. This composite approach leverages the advantages of both materials: the plastic provides structural integrity and form, while the rubber-elastic elements provide secure mechanical attachment through elasticity and friction, achieving both rapid installation and sufficient connection strength

AI summary
An air guide device for a vehicle has: a static carrier, which is installable via installation brackets on a body structure of the vehicle, which are connected at a first portion to the body structure and at a second portion to a carrier; an air guide displaceable relative to the static carrier between a retracted rest position and a deployed operating position; a kinematic link arrangement, which has multiple links via which the air guide is displaceable relative to the carrier, wherein the links of the kinematic link arrangement are mounted on first installation brackets; and an adjusting motor, which acts on the kinematic link arrangement for the purposes of displacing the air guide relative to the carrier. The adjusting motor is mounted on a second installation bracket. The carrier, which is made of plastic, is connected by a clip connection to the installation brackets, which comprise plastic or metal.
