Electromagnet Threaded Connection Particle Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Screwing connections between electromagnets and actuators can release particles that impair elastomer seals and cause functional issues, especially in valve applications where precise alignment and sealing are critical.
Innovation Solution
The implementation of chambers on both sides of the threads with narrow gap seals that prevent particle penetration and serve as static seals for precise alignment, using elastomer seals to protect the functional cavities and improve assembly precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a screw connection is used to join the electromagnet and actuator, then the components can be easily assembled and disassembled, but particles are released during screwing that can penetrate into functional cavities and damage elastomer seals
Solution Approach 1:
The space around the thread connection is segmented into separate chambers (first chamber on the actuator side, second chamber on the electromagnet side) that are isolated from the functional cavities by gap seals. This segmentation prevents particles generated during screwing from reaching the elastomer seals and functional spaces, while maintaining the ease of screw connection assembly.
Solution Approach 2:
Gap seals are introduced as intermediary elements between the thread connection and the functional cavities. These static seals act as barriers that prevent particle penetration into the elastomer seal areas, while allowing the screw connection to remain functional for assembly and disassembly.
2Ease of manufacture
If a screw connection is used, then the components can be joined together, but the alignment precision between components is insufficient due to thread play
Solution Approach 1:
The invention merges two functions into a single integrated structure: the gap seals simultaneously provide both sealing (preventing particle penetration) and precise alignment of the electromagnet and actuator components. This eliminates the need for separate alignment features while maintaining assembly ease.
Solution Approach 2:
The gap seals are designed to perform multiple functions: they act as static seals to prevent particle penetration into functional cavities, and simultaneously serve as alignment features that ensure precise positioning of the components relative to each other, replacing the need for separate alignment mechanisms.
3Reliability
If gap seals are introduced to prevent particle penetration, then seal protection is improved, but the device complexity increases
Solution Approach 1:
The gap seals are positioned locally at the critical interfaces where particle penetration would occur (between the thread chambers and functional cavities). This localized approach provides effective seal protection without requiring complex structures throughout the entire device, maintaining simplicity while improving reliability.
