Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical interconnection schemes are used for filter cartridge installation, then the structure is simple and manufacturing cost is low, but fluid leakage into electronic components occurs during installation or operation
Solution Approach 1:
The patent replaces traditional mechanical interconnection and actuation systems with a magnetic field-based system. Correlated magnets on the filter cartridge interact with magnets in the manifold to provide both mechanical retention and non-contact actuation of electronic components, eliminating the need for mechanical linkages that could leak fluid while maintaining structural simplicity.
Solution Approach 2:
The magnetic field serves as an intermediary between the filter cartridge installation and the actuation of electronic components. The correlated magnets transmit force and information without physical contact, enabling reliable actuation of valves or switches during installation without requiring direct mechanical connection that could compromise sealing.
2Ease of operation
If electronic components are directly connected to filter interconnection mechanisms, then actuation is precise and controllable, but fluid leakage into electronic components becomes possible
Solution Approach 1:
The patent substitutes direct mechanical connection between filter interconnection mechanisms and electronic components with a magnetic field-based actuation system. The correlated magnets enable precise non-contact actuation of electronic components during filter cartridge installation, eliminating fluid pathways that could lead to leakage while maintaining controllable and precise operation.
3Reliability
If correlated magnets are used for non-contact actuation, then fluid leakage is prevented and authentication is provided, but manufacturing complexity and cost increase
Solution Approach 1:
The correlated magnet system performs multiple functions simultaneously: it provides mechanical retention of the filter cartridge, enables non-contact actuation of electronic components, prevents fluid leakage through non-contact operation, and provides authentication through the specific magnetic field pattern. This multi-functionality reduces the need for separate components, offsetting the manufacturing complexity with functional consolidation.
4Adaptability or versatility
If traditional mechanical actuation is used during filter installation, then the system is simple, but fluid may leak into electronic components and authentication is not provided
Solution Approach 1:
The patent replaces traditional mechanical actuation systems with correlated magnetic fields that provide non-contact operation. This substitution enables versatile functionality including fluid-tight sealing, authentication through magnetic field correlation, and precise actuation of electronic components during filter installation, while the magnetic system itself remains relatively simple in structure.

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.
