Electromagnet Armature Seal Retention for Stable Stroke
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnets face challenges in cost-effective and energy-efficient production and assembly due to expensive and energy-intensive fastening methods for sealing elements, which can lead to reduced seal quality over time due to swelling and temperature influences.
Innovation Solution
The electromagnet employs a non-positive or positively locking connection for the sealing element, allowing it to expand independently without affecting armature stroke, and uses a supporting spring to maintain sealing quality, eliminating the need for integrally joined connections and complex vulcanization processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive bonding is used to fasten the sealing element to the guiding element, then the sealing element is securely fixed, but production costs increase due to additional method steps and energy consumption increases
Solution Approach 1:
The patent replaces chemical bonding methods (adhesive bonding, vulcanizing, welding) with a purely mechanical retention system. The sealing element is held in the guiding element through geometric interlocking features such as a retention groove and retention protrusion, eliminating the need for additional bonding steps and reducing energy consumption during assembly.
2Reliability
If integrally joined fastening is used to secure the sealing element, then the sealing element is firmly fixed, but production costs and assembly complexity increase
Solution Approach 1:
The patent divides the closure element into separate components: the guiding element and the sealing element. The sealing element can be manufactured independently and then assembled into the guiding element through a simple retention mechanism, reducing production complexity and allowing for specialized manufacturing of each component.
Solution Approach 2:
The patent replaces complex integrally joined fastening methods with a simple mechanical retention system using geometric interlocking features, significantly simplifying the manufacturing and assembly processes while maintaining secure fixation.
3Strength
If vulcanizing is used to fasten the sealing element, then strong bonding is achieved, but production costs increase and adhesion problems occur
Solution Approach 1:
The patent replaces thermal chemical bonding (vulcanizing) with a purely mechanical retention system using geometric interlocking features. This eliminates the need for vulcanization chambers, complex mold insertion, and adhesion promoter coatings, significantly reducing production complexity while maintaining secure fixation.

AI summary
An electromagnet which is penetrated by a longitudinal axis includes: an armature space and an armature which is arranged longitudinally movably in the armature space, the armature having a penetration opening, and the armature supporting at least one closure element which is mounted movably in the penetration opening, the closure element being configured to open or to close the nozzle, the closure element comprising a guiding element, which guides the closure element in the penetration opening, and a sealing element which is supported by the guiding element, wherein the sealing element is held in a non-positive and/or positively locking or floating manner on the guiding element.
