Vehicle Air Filter Layout for Compact Front-End Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air cleaning devices for vehicles require a long air duct, increasing space in the front area and complicating filter replacement, as the filter is often inaccessible for easy maintenance.
Innovation Solution
The filter is positioned below the luggage compartment with a holding device allowing linear displacement for easy installation and removal, eliminating the need for additional accessibility in the engine compartment, and integrating a cooling module within the air duct for efficient air purification and cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter is arranged upright behind the luggage compartment with a long air duct, then the air purification function is achieved, but the space required in the front area of the vehicle increases
Solution Approach 1:
The filter arrangement is changed from a horizontal/longitudinal configuration to a vertical configuration beneath the luggage compartment. The air duct is routed vertically up through the luggage compartment floor, utilizing the vertical dimension to achieve compact packaging while maintaining the required air intake function.
Solution Approach 2:
The filter housing and air duct are integrated into the existing luggage compartment structure. The air duct passes through the luggage compartment floor, nesting the air purification system within the vehicle's existing spatial framework rather than adding separate external components.
2Reliability
If the filter is firmly attached in the air duct, then the air purification function is stable, but the filter replacement becomes difficult
Solution Approach 1:
The filter mounting system transitions from a static firmly attached configuration to a dynamic removable configuration. The filter housing includes engagement features that provide secure attachment during operation but allow intentional removal when needed, enabling both stable operation and easy maintenance.
Solution Approach 2:
The filter system is divided into separable components: the filter element housed in a removable filter housing that can be detached from the air duct assembly. This segmentation allows the filter to be replaced independently without disturbing the entire air duct system.
3Ease of repair
If the filter is made accessible from the engine compartment, then filter replacement is easy, but additional accessibility requirements increase device complexity
Solution Approach 1:
The luggage compartment floor serves multiple functions: it provides the structural floor for luggage storage and simultaneously serves as the access point for filter replacement. The opening in the luggage compartment floor is used both for placing objects and for servicing the filter, eliminating the need for separate access structures.

AI summary
The invention relates to a device for cleaning ambient air in a vehicle, comprising a filter for filtering the ambient air, an air duct by means of which the ambient air is guided from an air inlet to the filter, a luggage compartment arranged above at least a part of the air duct, wherein the filter is arranged below the luggage compartment, and a holding device is provided such that the filter can be moved by linear displacement from a mounting position in which the filter is located in the air duct to a dismounting position in which the filter is located outside the air duct.
