Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter units for hydraulic systems require additional design effort and installation space for magnetic pre-filtration, and the magnetic components can disrupt fluid flow and are not effectively integrated for efficient contamination removal, particularly for small particles.
Innovation Solution
Incorporating magnetizable and/or magnetized particles, such as neodymium-iron-boron particles, into the filter element's design, either as a coating or integrated within the filter housing, to facilitate magnetic separation without the need for separate magnetic components, ensuring minimal space usage and uncomplicated integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate magnetic components (magnetic candles) are used for magnetic pre-filtration, then magnetic separation function is achieved, but device complexity and installation space increase
Solution Approach 1:
The patent combines the magnetic separation function with the filter element by integrating magnetizable particles directly into the filter medium. This merging of functions eliminates the need for separate magnetic candles, reducing device complexity and installation space while maintaining effective magnetic pre-filtration capability
Solution Approach 2:
The filter element is designed to perform multiple functions simultaneously: mechanical filtration through the filter medium and magnetic separation through the integrated magnetizable particles. This multi-functionality allows a single component to replace what would traditionally require separate magnetic components
2Reliability
If magnetic components are placed in the inflow area, then magnetic pre-filtration occurs, but fluid flow is disrupted in an undesired manner
Solution Approach 1:
The magnetizable particles are distributed throughout the filter element structure rather than concentrated in the inflow area. This local distribution allows magnetic separation to occur across the entire filtration path without creating flow disruption zones, maintaining uniform fluid flow while achieving effective magnetic pre-filtration
3Reliability
If magnetizable particles are applied to the component, then magnetic separation function is integrated, but manufacturing complexity increases
Solution Approach 1:
The magnetizable particles are applied to the porous structure of the filter element, allowing the particles to be embedded within the porous matrix. This approach integrates the magnetic function during the manufacturing process itself, utilizing the existing porous structure rather than requiring additional assembly steps
