Air Filter Lid Terminal Disk Unitary Component
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air filters require multiple handling steps and risk assembly errors when replacing the filter element, and may not ensure a fluid-tight seal without additional sealing elements.
Innovation Solution
The releasable lid is integrated as a terminal disk of the filter element, forming a unitary component that simplifies handling and provides a fluid-tight connection, with a support grid maintaining the filter medium's shape and a safety element preventing dirt penetration, and the lid is designed with a radial collar and annular beads for secure positioning and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid and filter element are separate components, then the housing can be opened for maintenance, but multiple handling steps and assembly errors occur during filter element replacement
Solution Approach 1:
The lid and filter element are merged into a single unitary component. The lid is designed as a terminal disk that forms an integral part of the filter element, eliminating the need for separate handling of these two components during installation and removal operations.
Solution Approach 2:
The integrated lid-filter element component performs multiple functions simultaneously: it serves as both the closure lid for the housing and the terminal disk for the filter element, reducing the number of separate parts needed in the system.
2Reliability
If the lid is integrated as a terminal disk of the filter element, then assembly errors are prevented, but the structural design becomes more complex
Solution Approach 1:
The lid and terminal disk functions are merged into a single integrated component, ensuring that when the filter element is installed, the housing is automatically and correctly sealed, eliminating assembly errors.
3Reliability
If additional sealing elements are used to ensure fluid-tight connection, then sealing reliability is improved, but the device complexity and number of components increases
Solution Approach 1:
A flexible sealing ring is used to create the fluid-tight connection between the integrated lid-filter element and the housing. This single flexible sealing element provides reliable sealing without requiring multiple rigid sealing components.

AI summary
A filter has a housing and a filter element with a first filter medium, wherein the filter element is arranged in the housing. A releasable lid is provided at an end face of the housing and closes off the housing. The releasable lid and the filter element together form a unitary component and the releasable lid forms a terminal disk at a first end of the filter element. The releasable lid forming the terminal disk of the filter element is glued to an end face of the first filter medium. The unitary construction of the filter element and the lid simplifies changing the filter element.
