Modular Multi-Stage Water Treatment Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water treatment filters for appliances are typically fixed in size and disposable, lacking customization and requiring tools for installation, which limits their adaptability and maintenance.
Innovation Solution
A customizable multi-stage fluid treatment assembly comprising a connector, base cartridge, and variable cartridges with removably engaged filter media, allowing for easy hand-tool-free installation and maintenance, with a sealed housing configuration for efficient water flow through multiple treatment stages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If water filters are made compact and tool-free for appliance installation, then ease of installation and compactness are improved, but customization capability and maintenance flexibility deteriorate
Solution Approach 1:
The filter assembly is divided into modular cartridges that can be independently installed, removed, and replaced. Each cartridge contains specific filter media and can be customized for different filtration needs, enabling both easy tool-free installation and flexible customization without requiring tools.
2Ease of manufacture
If water filters are made disposable with fixed filtering capabilities, then manufacturing simplicity and reliability are improved, but maintenance cost and environmental impact worsen
Solution Approach 1:
The modular cartridge design allows selective replacement of only the filter media elements that become exhausted, while retaining the housing and other functional components. This extends the usable life of the filter assembly and reduces waste compared to complete disposable filters, while maintaining manufacturing simplicity through standardized modular components.
3Reliability
If multi-stage filtration is implemented with multiple cartridges, then filtration effectiveness is improved, but device complexity and installation difficulty worsen
Solution Approach 1:
Multiple filter cartridges are nested within a single housing structure, with each cartridge performing a specific filtration stage. This nested arrangement provides multi-stage filtration effectiveness while maintaining a compact, unified appearance and simplifying installation to a single tool-free operation rather than multiple separate installations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible and efficient water treatment with customizable filter media, extending the life of the assembly and simplifying maintenance, while ensuring effective filtration without the need for tools.
Implementation Method 1
A treatment medium is spaced within the interior volume between the first and second ends, such that the first and second ends of the base cartridge are configured to receive a fluid, bring the fluid into operative contact with the treatment medium
Implementation Method 2
A first filter medium is spaced within the first inside volume between the first coupler end and the first receiver end, such that the first coupler and the first receiver ends of the first variable cartridge are configured to receive the fluid, bring the fluid into operative contact with the first filter medium

AI summary
A customizable multi-stage fluid treatment assembly typically includes a connector, a plurality of cartridges, and a cap. The plurality of cartridges have a treatment medium spaced within an interior volume of the individual cartridges, between the ends thereof. The ends of the plurality of cartridges are configured to receive a fluid, bring the fluid into operative contact with the treatment medium, and dispense the fluid from the opposing end of the cartridge. The connector is coupled with one end of the plurality of cartridges and has an inlet and an outlet for receiving and dispensing the fluid to and from an appliance. The cap is coupled with the other end of the plurality of cartridges, enclosing the fluid treatment assembly, which is configured to be received in a cavity of an appliance. The cartridges of the plurality of cartridges may be individually replaced with cartridges to meet customized needs.
