Modular Air Filter Assembly With Reversible Airflow Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air filter assemblies are often designed specifically for a particular machine model, limiting their adaptability and requiring replacement of the entire assembly instead of individual components, and do not allow for flexible airflow direction adjustments.
Innovation Solution
A modular air filter assembly with a configurable inlet, outlet, and mounting assembly, allowing for radial orientation adjustments and independent configuration of airflow direction, enabling versatile installation and repairability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If air filter assemblies are designed with fixed or molded components for a particular machine model, then the assembly fits well within the specific engine bay, but the assembly cannot be modified or reused in different machine models
Solution Approach 1:
The air filter assembly is divided into separate modular components including the housing, inlet, outlet, and mounting brackets. Each component can be independently selected and configured based on the specific machine model requirements, allowing the same basic assembly to adapt to different engine bays without requiring complete redesign.
Solution Approach 2:
The modular components are designed with standardized interfaces and multiple configuration options (e.g., inlet positioned at different locations on the housing, outlet with various orientations) that allow a single set of components to serve multiple machine models and applications, enhancing universal applicability.
2Ease of repair
If components of air filter assemblies are fixed or molded together, then the assembly structure is simplified, but the user cannot repair individual components and must replace the entire assembly
Solution Approach 1:
The assembly uses separate, detachable components connected through standardized interfaces rather than being molded as a single piece. This segmentation enables individual components such as the inlet, outlet, or mounting brackets to be replaced independently when damaged or worn, reducing material waste and repair costs.
Solution Approach 2:
When a component becomes worn or damaged, only that specific component needs to be replaced while the rest of the assembly can be retained and reused. This selective replacement approach recovers valuable materials and reduces waste compared to replacing the entire assembly.
3Adaptability or versatility
If the outlet, supports, and dust ejector tube are integral to the housing, then the assembly structure is simplified, but the assembly cannot be adapted to machines with different spatial requirements
Solution Approach 1:
The outlet and support components are designed to be reconfigurable and adjustable rather than fixed in single positions. The outlet can be oriented in different directions, and supports can be positioned at various locations on the housing, allowing the assembly to adapt to different spatial constraints in various machine models.
Solution Approach 2:
The components provide adjustment capabilities in multiple dimensions - the outlet can be positioned at different angular orientations, and supports can be located at various radial positions around the housing. This multi-dimensional configurability enables adaptation to diverse installation environments.
4Adaptability or versatility
If the inlet is fastenable at two or more orientations, then some airflow direction flexibility is provided, but the rotation of airflow within the housing cannot be changed
Solution Approach 1:
The inlet cap can be rotated and fastened at different orientations relative to the housing, and this rotation directly changes the airflow pattern within the housing - enabling either clockwise or counter-clockwise circulation depending on the inlet orientation. This dynamic configuration allows users to optimize airflow direction for different operational requirements.

AI summary
Modular air filter assemblies having a configurable inlet, a configurable outlet, and a configurable mounting assembly are described herein. The modular filter assembly includes a tube, an end cap, an outlet cap, and an inlet cap. The tube defines a filter chamber, extends from a first end to a second end, and is configured to receive a filter. The end cap is at the first end. The outlet cap includes an outlet and a flange defining a plurality of holes and extending radially outward from the outlet cap. The outlet cap is fastenable via the plurality of holes to the second end of the tube at a plurality of radial orientations. The inlet cap is fastenable to the tube in a first configuration, in which air circulates in a counter-clockwise direction, and a second configuration, in which air circulates in a clockwise direction.
