Air Filter Mating Interface Press-Fit Groove Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mating interfaces between air intake housings and air filters often require external fasteners, which can lead to installation complexity and potential leaks, compromising the sealing and durability of the air filter assembly.
Innovation Solution
A mating interface design that includes a groove on the air filter housing for a press-fit connection with the air intake housing, eliminating the need for external fasteners, and featuring a flange that is radially pressed against the housing by the air tube, along with optional features like screw threads, polyurethane material, and draft or rib designs for enhanced sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external fasteners are used to connect air intake housing and air filter, then the connection can be secured, but the installation complexity increases and potential leaks occur
Solution Approach 1:
The groove and flange features are integrated directly into the mating interface between the air intake housing and air filter, combining the connection and sealing functions into a single unified structure that eliminates the need for separate external fasteners
Solution Approach 2:
The flange is radially pressed against the air filter housing by the air tube itself, allowing the air tube to automatically perform the sealing function without requiring external fasteners or additional components
2Reliability
If external fasteners are used to connect air intake housing and air filter, then the connection can be secured, but the installation process becomes more difficult
Solution Approach 1:
External fasteners are completely removed from the design, extracting the unnecessary components that complicate installation while retaining the essential connection and sealing functions through the integrated groove and flange structure
Solution Approach 2:
The connection and sealing functions are merged into the mating interface itself through the groove and flange design, creating a single-step installation process that is both simple and durable
3Ease of operation
If a press-fit connection is used without external fasteners, then installation is simplified, but the sealing reliability may be compromised
Solution Approach 1:
The air tube automatically performs the sealing function by radially pressing the flange against the air filter housing through its own installation process, eliminating the need for external fasteners while maintaining reliable sealing
Solution Approach 2:
The flange is positioned at the specific location where sealing is needed, and its radial pressing action creates a localized high-pressure sealing zone that ensures reliable connection without requiring fasteners throughout the entire assembly

AI summary
Mating interfaces between an air intake housing and an air filter are disclosed. According to one embodiment, an air filter assembly having a mating interface for coupling an air intake housing to the air filter may include an air filter having an exterior, an interior, and outlet; and a mating interface coupled to a circumference of the outlet of the air filter. The mating interface may include an opening for receiving an end of an air tube that is in communication with the interior of the air filter; and a groove in a surface of the mating interface for press-fit receiving a first opening an air filter housing that surrounds the air filter.
