Serial Flow Filter Cartridge for Water Purification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water purifier filter cartridges require separate replacement of filters with different cycles, leading to increased maintenance costs and resource wastage, and limit the amount of purified water that can be produced due to the need for multiple cartridges and additional components.
Innovation Solution
A serial flow channel type filter cartridge with a cartridge header that accommodates multiple filter bodies and housings, allowing tap water to flow sequentially through each filter body before discharge, reducing the need for additional components and simplifying maintenance by integrating multiple filtration stages into a single cartridge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple filter cartridges are separately replaced for each filter having different replacement cycles, then each filter can be maintained according to its specific cycle, but maintenance costs increase and resource wastage occurs
Solution Approach 1:
The patent combines multiple filter cartridges with different replacement cycles into a single integrated cartridge assembly. The cartridge header houses multiple filter bodies (first filter body, second filter body, etc.) that can be replaced together as one unit, eliminating the need for separate replacements and reducing maintenance costs while maintaining flexibility through selective filter body configuration.
Solution Approach 2:
The cartridge header is designed as a universal component that can accommodate multiple different types of filter bodies simultaneously. The standardized connection structure allows various filter bodies to be mounted on the same header, enabling a single cartridge assembly to serve multiple filtration functions with different replacement cycles.
2Productivity
If only one filter cartridge is mounted on a single filter head, then the structure is simple, but the amount of purified water is limited
Solution Approach 1:
The patent merges multiple filter cartridges into a single integrated cartridge assembly that mounts on one filter head. The cartridge header contains multiple filter bodies arranged in parallel or series configurations, allowing a single mounting point to deliver the combined purified water output of multiple filters, thereby increasing productivity without proportionally increasing device complexity.
Solution Approach 2:
The filter bodies are nested within the cartridge header structure, with each filter body housed in its own chamber or compartment within the header. This nested arrangement allows multiple filters to be compactly integrated into a single cartridge assembly that occupies the space of one traditional filter cartridge, enabling increased purified water output without proportionally increasing external dimensions.
3Productivity
If multiple filter cartridges are used to increase purified water amount, then productivity increases, but additional components and resources are wastefully used
Solution Approach 1:
The patent merges multiple filter bodies into a single cartridge assembly with a shared cartridge header, connection structure, and mounting interface. This consolidation eliminates the need for multiple separate cartridges, connection components, and mounting hardware, reducing resource usage while maintaining the combined purified water output capacity of multiple filters.
Solution Approach 2:
The cartridge header serves as a universal platform that houses multiple filter bodies and provides unified connection to the water purifier system. This multi-functional design allows a single cartridge assembly to replace multiple individual cartridges, reducing the total number of components needed while achieving the same or greater purified water production capacity.
4Reliability
If separate filter cartridges are used for different filtration functions, then each filter can be optimized for its specific function, but maintenance and repair become difficult
Solution Approach 1:
The patent combines multiple filter bodies into a single cartridge assembly that is replaced as one unit. This merging simplifies maintenance by eliminating the need to individually access and replace each filter body, as the entire assembly with all filter bodies can be quickly removed and replaced together, significantly improving ease of repair while maintaining functional optimization.
Solution Approach 2:
While the overall cartridge assembly is replaced as one unit, the filter bodies within the assembly can be segmented or modularly arranged to allow for functional optimization. Each filter body maintains its specific filtration function (e.g., sediment filtration, carbon filtration, membrane filtration) while being integrated into the unified replaceable cartridge structure, balancing functional specialization with maintenance simplicity.
