Removable Dual-Stage Water Filter for Cleanable Inline Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inline water filters have a limited lifespan, are disposable, and cannot be easily cleaned or replaced, leading to frequent disposal and increased costs for consumers.
Innovation Solution
A compact water filter system comprising a pre-filter and primary filter, both removably housed within a single unit, allowing for easy replacement and cleaning of filters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inline filters are made disposable to ensure reliable filtration, then filtration reliability is improved, but loss of substance and loss of time increase due to frequent disposal and replacement
Solution Approach 1:
The patent enables recovery and reuse of the filter cartridge by providing a cleaning system that flushes contaminants from the filter medium. The filter cartridge can be removed from the housing, cleaned by flushing with water through the cleaning aperture, and then reused, thereby reducing waste while maintaining filtration reliability.
Solution Approach 2:
The filter system provides self-service cleaning capability where the filter cartridge can be easily cleaned by the user without specialized equipment. The housing structure with its cleaning aperture and flush aperture allows the user to simply flush water through the filter medium to remove contaminants and restore filtration performance.
2Loss of substance
If filters are made removable and cleanable to reduce waste, then loss of substance decreases, but device complexity increases due to additional housing and mounting structures
Solution Approach 1:
The filter system is segmented into separate components: a removable filter cartridge and a housing with integrated cleaning features. The filter cartridge can be easily removed from the housing for cleaning or replacement, while the housing contains the mounting structure and cleaning apertures. This segmentation allows for simple maintenance without requiring complex disassembly.
Solution Approach 2:
The housing integrates multiple functions into a single structure: it provides mounting support for the filter cartridge, contains the cleaning aperture for flushing the filter medium, and provides the flush aperture for water inlet. This merging of functions reduces the need for separate components and simplifies the overall device structure.
3Volume of moving object
If filters are made compact to reduce space occupation, then volume decreases, but ease of operation decreases due to difficult access for cleaning and replacement
Solution Approach 1:
The filter cartridge is designed as a separate, removable component that can be easily extracted from the housing. The housing structure includes a removable cover or aperture that allows direct access to the filter cartridge for cleaning or replacement, maintaining ease of operation while keeping the overall system compact.

AI summary
A system and method is provided for filtering water using a pre-filter and a primary filter, both removably disposed within a housing. The pre-filter is placed in series with the primary filter. The pre-filter includes a cavity within which the primary filter may be at least in part disposed. In one embodiment, the pre-filter and the primary filter are each removably received within the housing, so that either or both of the pre-filter and primary filter may be easily removed from the housing and replacement filters provided. Thus, a simple, convenient, compact filtering apparatus is provided.
