Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interconnection schemes between filter cartridges and manifolds lack efficient mechanisms for attachment, detachment, and actuation of valves, leading to difficulties in fluid management and filter removal.
Innovation Solution
The use of correlated magnets in a "torque/align" model, where one magnet on the filter cartridge applies torque to a corresponding magnet on the manifold for alignment and actuation of a valve, and a repulsion force is utilized for filter removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional mechanical interconnection schemes are used between filter cartridges and manifolds, then the attachment mechanism is simple, but the valve actuation and alignment precision are insufficient
Solution Approach 1:
The patent replaces traditional mechanical alignment and attachment mechanisms with a magnetic field-based correlated magnet system. The correlated magnets generate precise alignment forces through magnetic interaction, eliminating the need for complex mechanical alignment features while achieving superior alignment precision between the filter cartridge and manifold.
Solution Approach 2:
The correlated magnet system performs multiple functions simultaneously: it provides precise alignment, secure attachment, and valve actuation through a single integrated mechanism. The same magnetic interaction that aligns the components also drives the valve, reducing the need for separate mechanical systems for each function.
2Reliability
If correlated magnets are used for valve actuation through rotation, then the fluid control precision is improved, but the device complexity increases
Solution Approach 1:
The patent uses magnetic torque from correlated magnets to replace traditional mechanical valve actuation mechanisms. The magnetic field directly induces rotation of the valve component, eliminating the need for separate actuators, linkages, or mechanical drive systems, thereby improving reliability while managing complexity.
Solution Approach 2:
The correlated magnet system is self-actuating through magnetic interaction. When the filter cartridge is installed, the magnetic field automatically generates the torque needed for alignment and valve actuation without requiring external mechanical inputs or additional control mechanisms, enhancing reliability.
3Ease of operation
If repulsion force is introduced for filter cartridge removal, then the ease of operation is improved, but the force control precision becomes challenging
Solution Approach 1:
The patent inverts the typical magnetic interaction by utilizing repulsion force for removal instead of attraction. By designing the correlated magnet system to generate repulsive forces during the removal phase, the filter cartridge can be easily detached without requiring significant manual force, improving ease of operation while the magnetic field naturally provides force control.
4Measurement precision
If multiple field emission sources are increased for better alignment precision, then the alignment precision is improved, but the manufacturing complexity increases
Solution Approach 1:
The correlated magnet system uses replicated magnetic field patterns that can be manufactured using standardized processes. The magnetic sources are arranged in specific geometric patterns that can be copied through precision manufacturing techniques, achieving high alignment precision while managing manufacturing complexity through pattern repetition and standardization.

Function Achieved in This Case
This solution enables efficient attachment and detachment of the filter cartridge, precise control of fluid flow through valve actuation, and facilitated removal of the filter cartridge due to the repulsion force, improving overall system functionality.
Implementation Method 1
When correlated magnets are brought into alignment with complementary or mirror image counterparts, the various magnetic field emission sources that make up each correlated magnet will align causing a peak spatial attraction force
Implementation Method 2
a repulsion force is introduced upon filter cartridge rotation to assist in the filter cartridge removal from the manifold
