Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art filter interconnects face technical hurdles such as fluid leakage into electronic components during installation or operation, and lack effective authentication and anti-counterfeiting measures, necessitating an improved interconnection scheme that prevents leakage and ensures proper installation without increasing manufacturing cost or complexity.
Innovation Solution
The use of correlated magnetism, specifically magnetic repulsion, to actuate a switch and assist in filter cartridge installation and removal, providing a non-electronic and non-contact method to engage downstream system functionality while preventing leakage and authenticating proper installation through magnetic communication between the filter cartridge and manifold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical interconnection is used between filter cartridge and manifold, then installation and removal are straightforward, but fluid leakage into electronic components occurs and authentication mechanisms are lacking
Solution Approach 1:
The patent replaces traditional mechanical interconnection with a magnetic field-based system. Correlated magnets embedded in both the filter cartridge and manifold create magnetic repulsion forces that prevent physical contact between the filter cartridge end cap and the manifold, thereby preventing fluid leakage into electronic components while maintaining a relatively simple interconnection scheme.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the filter cartridge and manifold. The correlated magnets generate magnetic repulsion that acts as a non-contact barrier, preventing direct mechanical contact and fluid leakage while still enabling authentication and controlled actuation of downstream functions.
2Productivity
If initial installation directly actuates valve, then system response is immediate, but fluid leakage risk increases during installation
Solution Approach 1:
The patent separates the installation process into distinct phases: first, the filter cartridge is installed and held in position by magnetic attraction; second, rotation of the filter cartridge actuates the correlated magnets to generate repulsion forces that open the valve. This preliminary positioning followed by controlled actuation prevents fluid leakage during installation while maintaining rapid system response.
Solution Approach 2:
The patent segments the installation and actuation processes into separate steps. The magnetic interconnection system allows the filter cartridge to be installed and secured independently from valve actuation. Rotation of the filter cartridge body relative to the manifold triggers the correlated magnets to switch from attraction to repulsion, thereby opening the valve only after proper installation is confirmed.
3Reliability
If correlated magnets are used for authentication, then anti-counterfeiting is achieved, but manufacturing cost increases
Solution Approach 1:
The correlated magnets serve multiple functions simultaneously: they provide authentication by verifying the presence of genuine filter cartridges through magnetic field interaction, prevent fluid leakage through non-contact repulsion forces, and enable controlled valve actuation through rotation-triggered magnetic switching. This multi-functionality reduces the need for separate authentication components, thereby limiting manufacturing cost increases.

Function Achieved in This Case

AI summary
A filtration system interconnection structure having a filter manifold including a sump housing and a first correlated magnet located on or connected to a portion of the manifold, and a filter cartridge including a filter media, first and second end caps sealed to the filter media, and a second, paired correlated magnet located on or connected to the filter cartridge housing body. The first and second correlated magnets are interconnected via magnetic communication upon insertion of the filter cartridge into the sump housing, and upon movement of the filter cartridge into an alignment position, the correlated magnet located on or connected to the manifold is permitted to translate as a result of the magnetic communication. The polarity profiles of the paired correlated magnets are aligned such that a repulsion force is created when the filter cartridge is inserted within the manifold sump housing.
