Filter Insert Flange Groove Design for High Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filters for removing oil from air compressors or vacuum pumps fail to maintain functionality at high pressures due to flange deformation, leading to disengagement or damage.
Innovation Solution
A filter insert with a hollow cylindrical filter element adhesively bonded to a flange featuring a flanged or folded edge and a bead forming a circular groove, enhancing the flange's stiffness and ensuring a reliable adhesive bond, even at extreme pressures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the flange thickness is increased to prevent deformation at high pressures, then the flange stiffness is improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The flange is segmented into multiple functional features: a groove formed by the edge and bead, adhesive bonding zones, and structural support regions. This segmentation allows each part to perform its specific function efficiently without requiring overall thickness increase
Solution Approach 2:
The flange combines sheet metal material with adhesive bonding to create a composite structure that achieves high stiffness and strength without increasing thickness. The adhesive layer acts as a bonding agent that reinforces the connection between the filter element and flange
2Reliability
If the flange thickness is increased to prevent deformation at high pressures, then the filter reliability is improved, but the production cost increases
Solution Approach 1:
The groove is pre-formed in the flange using the edge and bead structure before filter element installation. This preliminary action ensures proper adhesive placement and bonding geometry, leading to reliable high-pressure performance without requiring thick flanges
Solution Approach 2:
The invention changes the geometric parameters of the flange by introducing the groove depth, bead height, and edge configuration. These parameter changes optimize the bonding geometry and structural strength without increasing overall flange thickness
3Reliability
If a groove is introduced to improve adhesive bonding, then the adhesive bond reliability is improved, but the device complexity increases
Solution Approach 1:
The groove formation is merged with the existing flange edge and bead features. Rather than adding a separate groove component, the groove is created by the interaction between the flange edge and the bead, simplifying the overall structure while achieving reliable adhesive bonding
