Automotive Air Cleaner Integral Insulator Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air cleaning systems in automotive applications face inefficiencies due to the separate attachment of insulators, which can lead to vibration insulation issues and complex filter replacement processes.
Innovation Solution
An air cleaner assembly design featuring a first and second housing portion with a filter media and integral insulators, allowing for integrated vibration insulation and simplified filter replacement by using an air box clip or other fastening means for coupling, with the option of a filter skeleton for additional structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If insulators are attached separately to the filter media, then the air cleaner assembly can be assembled, but vibration insulation effectiveness is reduced and filter replacement becomes complex
Solution Approach 1:
The insulator is integrated directly into the filter media as a unified component, eliminating the need for separate attachment steps. This merging ensures the insulator remains properly positioned during operation for effective vibration insulation, while simultaneously simplifying filter replacement since the insulator moves with the filter media as a single replaceable unit.
2Ease of manufacture
If insulators are attached separately to the filter media, then the air cleaner assembly can be assembled, but the attachment process becomes complex and error-prone
Solution Approach 1:
The insulator is manufactured as an integral part of the filter media, combining two separate manufacturing processes into one. This eliminates the separate attachment step entirely, reducing assembly complexity and the potential for installation errors while maintaining effective vibration insulation.
3Object-affected harmful factors
If separate insulators are used with the filter media, then vibration insulation can be provided, but the overall component count and assembly complexity increase
Solution Approach 1:
The insulator function is merged with the filter media structure, creating a single integrated component that performs both filtration and vibration insulation functions. This reduces the total component count while maintaining effective vibration isolation between the air cleaner assembly and the vehicle engine.

AI summary
A number of variations may include an air cleaner assembly which comprises a first housing portion having at least one air inlet aperture. The air cleaner assembly may further include a second housing portion operably coupled to the first housing portion and having at least one air outlet aperture. Moreover, a filter media may be disposed between the first housing portion and the second housing portion. At least one insulator may be integrally formed with the filter media. The entire filter media including the insulator may be removable and replaceable.
