Magnet Housing Seal Layout for Contaminant-Resistant Conveyors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sealing elements for magnets in support and guide magnetic structures for conveyors with articulated links fail to provide a reliable barrier against unwanted substances, especially liquids, due to improper positioning and reliance on screws for attachment, leading to compromised functionality and assembly difficulties.
Innovation Solution
A sealing housing element with a notch and elastomeric gasket positioned closer to the openings to prevent substance ingress, combined with snap-connecting projections for secure attachment to the magnetic structure, ensuring effective sealing without additional fastening means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the sealing element is positioned close to the covering wall of the housing element, then the assembly is simpler, but the sealing reliability is insufficient
Solution Approach 1:
The sealing element is positioned on the lateral surface of the housing element rather than on the covering wall, creating a multi-level sealing arrangement. This spatial repositioning allows the sealing element to be located deeper in the cavity while maintaining assembly simplicity through the integrated notch design.
2Reliability
If the sealing element is positioned deeper in the cavity, then the sealing reliability is improved, but the assembly complexity increases
Solution Approach 1:
The notch for housing the sealing element is integrated directly into the housing element structure during manufacturing, rather than being added as a separate component. This merging of the sealing feature into the main housing structure achieves deep positioning for reliable sealing without increasing overall assembly complexity.
3Reliability
If magnets are housed in housing elements with ferromagnetic plates, then the magnetic function is achieved, but the assembly difficulty increases due to magnet attachment to incorrect positions
Solution Approach 1:
The housing element is pre-assembled with the ferromagnetic plate and sealing element integrated into its structure before the magnets are installed. This preliminary preparation of the housing element ensures that when magnets are placed, they are guided to the correct positions without attaching to wrong locations on the ferromagnetic plate.

Function Achieved in This Case
The solution provides a simple, economical, and functional seal that effectively prevents the entry of unwanted substances into the magnet housings, enhancing the reliability and ease of assembly of the magnetic structure.
Implementation Method 1
a sealing element, which is generally manufactured in the form of an O-ring, positioned close to the covering wall of the housing element

AI summary
A housing element (1) for the magnets (12, 14) of a support and guide magnetic structure (100) for conveyors (102) with articulated links is described. The housing element comprises a box-shaped body (10) comprising two seats (24, 26) for the magnets, openings (28, 30) for inserting the magnets in the seats, a housing portion (32) for a ferromagnetic plate (34), which is designed to come into contact with the magnets, and at least one retaining portion (36) to retain the magnets to the box-shaped body. The retaining portion is shaped and sized in such a way that it can retain the magnets by friction, while the plate is held in the respective housing portion by the magnetic force of the magnets. On the external surface of the box-shaped body at least one notch (38), which is designed to house and retain at least one corresponding sealing element (40), is obtained. This sealing element is arranged to prevent the access of unwanted substances inside the seats of the magnets and the housing portion when the housing element is mounted onto the support and guide magnetic structure.
