Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air filter systems for motor vehicles do not effectively manage airflow separation and velocity, leading to inefficiencies in air filtration and mass air flow meter performance.
Innovation Solution
A dual outlet air filtering assembly with separate airflow chambers and arcuate filter elements, including an airfoil cone in the interior flow chamber to enhance airflow velocity and minimize pressure loss, is introduced. The assembly features a common housing with two D-shaped filter elements and a common cover, allowing for independent airflow management through each chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single air filter assembly is used for multiple cylinders, then device complexity is reduced, but airflow separation and velocity management become insufficient
Solution Approach 1:
The air filter assembly is segmented into multiple independent airflow chambers, each with its own filter element and airflow path. This allows each chamber to manage airflow independently, maintaining sufficient airflow velocity for each cylinder while keeping the overall device complexity manageable through modular design
2Speed
If arcuate filter elements are used, then airflow velocity is increased, but pressure loss increases
Solution Approach 1:
Arcuate filter elements with curved surfaces are used to increase airflow velocity by creating a more streamlined flow path. The curvature helps maintain higher velocity while reducing turbulence-related pressure losses compared to straight filter elements
3Speed
If separate airflow chambers are used for each cylinder, then airflow velocity and separation are improved, but device complexity increases
Solution Approach 1:
The housing is divided into separate airflow chambers, each with its own filter element, allowing independent airflow management for each cylinder. This segmentation improves airflow velocity and separation while maintaining manageable complexity through modular design
Solution Approach 2:
The common housing structure serves multiple functions: it provides structural support, contains multiple airflow chambers, and manages airflow distribution to multiple cylinders. This multi-functionality reduces the need for additional separate components, balancing complexity with performance
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration improves airflow separation and mass air flow meter performance by increasing airflow velocity at lower rates while maintaining low pressure loss, enhancing the overall efficiency of air filtration for internal combustion engines.
Implementation Method 1
at least one airfoil cone can be arranged in the interior flow chamber. With the at least one airfoil cone an airflow in the interior flow chamber can be influenced. In particular, the airflow velocity at lower flow rates can be increased while minimizing an increase in pressure loss
Implementation Method 2
The arcuate filter media has a U-shape with an open side. The arcuate filter media arcuately extends between a first end and a second end. The air filter element radially receives airflow through the arcuate filter media into the interior and axially directs the airflow out of the air filter element

AI summary
An air filter system for a motor vehicle includes a common housing, first and second D-shaped filter elements and a common cover. The common housing defines a first airflow chamber extending between a first inlet duct and a first outlet duct and a second airflow chamber extending between a second inlet duct and a second outlet duct. The first airflow chamber is fluidly separated from the second airflow chamber. The first D-shaped filter element is disposed in the first airflow chamber for filtering air passing through the first airflow chamber. The second D-shaped filter element is disposed in the second airflow chamber for filtering air passing through the second airflow chamber. The common cover is secured to the housing and closes the first airflow chamber and the second airflow chamber.
