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 they lack flexibility in airflow direction and mounting options.
Innovation Solution
A modular air filter assembly with a configurable inlet and outlet, allowing for adjustable airflow direction and multiple mounting orientations, enabling it to be adapted to various machine models and facilitating component replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If air filter assemblies are designed with fixed components molded together for a particular machine model, then manufacturing precision and structural integrity are improved, but adaptability and ease of repair deteriorate
Solution Approach 1:
The air filter assembly is divided into separate modular components including a housing, inlet cap, outlet cap, and filter element. These components can be independently manufactured, assembled in different configurations, and replaced individually, resolving the contradiction between structural integrity and adaptability.
Solution Approach 2:
The housing is designed with multiple configurable inlet and outlet positions that can accommodate different machine models and airflow requirements. This universal design allows the same basic assembly to serve multiple functions and applications, improving adaptability while maintaining manufacturing precision through standardized components.
2Device complexity
If air filter assemblies use fixed molded components for a particular machine model, then device complexity is reduced, but ease of repair and adaptability deteriorate
Solution Approach 1:
By segmenting the assembly into replaceable modules (inlet cap, outlet cap, filter element), the design maintains relatively simple individual components while enabling easy repair through selective replacement. This resolves the contradiction by showing that simple components can be arranged in modular configurations that facilitate maintenance.
3Manufacturing precision
If air filter assemblies are designed with fixed airflow direction for a particular machine model, then manufacturing precision is improved, but adaptability deteriorates
Solution Approach 1:
The inlet and outlet caps are designed to be rotatable or reconfigurable relative to the housing, allowing the airflow direction to be dynamically adjusted to match different machine configurations. This maintains manufacturing precision through standardized interfaces while providing adaptability through adjustable positioning.
Solution Approach 2:
Multiple inlet and outlet ports are pre-configured at different positions on the housing during manufacturing. This preliminary preparation of multiple possible configurations allows the assembly to be adapted to different airflow requirements without requiring complex modifications, resolving the contradiction between precision manufacturing and adaptability.
4Device complexity
If air filter assemblies use integral components for a particular machine model, then device complexity is reduced, but loss of time for replacement increases
Solution Approach 1:
The assembly is segmented into independently replaceable components, allowing users to replace only the filter element or specific caps rather than the entire assembly. This maintains relatively simple overall device structure while dramatically reducing replacement time through selective component replacement.

AI summary
Modular air filter assemblies having a configurable inlet, a configurable outlet, and configurable mounting assembly are described herein. The modular filter assembly includes a tube, an aperture extending through a wall of the tube, an end cap at a first end of the tube, an outlet cap at a second end of the tube, and an inlet cap. The tube extends along a central axis from a first end to a second end and is configured to receive a filter. The inlet cap is configured to be fastened to the aperture in a first configuration and a second configuration, different from the first configuration. The inlet is in communication with the aperture in each of the first configuration and the second configuration.
