Gas Filter Adhesive Bead Force Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter elements for gas filtration, such as air filters in internal combustion engines, face challenges in stability and risk of damage during installation, leading to potential leakage and reduced service life due to uneven force distribution and lack of effective sealing.
Innovation Solution
Incorporating adhesive beads between sealing or supporting elements at the inflow and outflow sides of the filter medium body, which act as force-transmitting elements, to ensure proper seating and sealing within the filter housing, thereby reducing the stress on the filter medium body and enhancing its stability and service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the filter element is installed in the filter housing without adhesive beads as force-transmitting elements, then the installation process is simpler, but the filter medium body is subjected to uneven forces leading to potential damage and reduced stability
Solution Approach 1:
The adhesive bead acts as an intermediary element between the sealing/supporting elements and the filter medium body. It transmits forces uniformly distributed along the adhesive bead's length, preventing concentrated loads on the filter medium body while ensuring stable connection between components.
Solution Approach 2:
The force transmission path is segmented into distinct functional elements: sealing elements at the ends, adhesive beads as intermediate force-transmitting elements, and the filter medium body. This segmentation allows each element to perform its specific function optimally without subjecting the filter medium to excessive or uneven forces.
2Productivity
If the filter element is installed without proper force transmission elements, then the installation process is faster, but leakage flows occur due to insufficient sealing and improper seating
Solution Approach 1:
The adhesive bead serves as a mediator that ensures proper force transmission from the sealing elements to the filter medium body, guaranteeing effective sealing and preventing leakage flows while maintaining installation efficiency.
Solution Approach 2:
The adhesive bead is pre-applied to the filter medium body before installation, creating a ready-made force transmission path that ensures proper seating and sealing immediately upon installation, eliminating the need for additional sealing steps.
3Device complexity
If the filter medium body directly transmits clamping forces during installation, then the structure is simpler, but the filter medium body is damaged due to excessive stress leading to reduced service life
Solution Approach 1:
The adhesive bead acts as a protective intermediary that distributes clamping forces along its length, preventing concentrated stresses on the filter medium body and thereby extending its service life without adding significant structural complexity.
Solution Approach 2:
The adhesive bead provides beforehand cushioning by absorbing and distributing installation forces before they reach the filter medium body, preventing damage and extending the operational life of the filter element.

AI summary
A filter element has a filter medium body with a first side and an oppositely positioned second side, wherein one of the first and second sides is the inflow side of the filter medium body and the other one is the outflow side of the filter medium body. A first sealing or supporting element is arranged at the first side. A second sealing or supporting element is arranged at the second side. At least one force-transmitting adhesive bead extends between the first side and the second side, wherein the at least one adhesive bead is a force transmitting element extending between the first and second sealing or supporting elements.
