Solution Overview
Problem
Traditional water filters, whether in cylinder or disc form, face challenges such as reduced filtration efficiency due to short residence time, bulky construction, and channeling issues with granular filtering materials, which compromise the quality and volume of filtered water.
Innovation Solution
A compact fluid filter design featuring a filter media with multiple layers, including nylon, activated carbon, and nanofiber layers, arranged to create a tortuous flow path within a disc-shaped housing, along with an air release device to manage air pockets, ensuring extended residence time and efficient filtration without occupying excessive space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cylinder form filter is used to increase filtration depth, then filtration efficiency is improved, but the filter occupies significant space and reduces flow rate
Solution Approach 1:
The patent transitions from a vertical cylindrical filter to a horizontal disc-shaped filter, changing the primary dimension of filtration depth from vertical to radial. This allows the filter media to extend outward horizontally rather than downward vertically, achieving extended residence time without increasing the vertical footprint in the container.
Solution Approach 2:
The filter media is configured as a disc shape with curved radial flow paths, creating a tortuous flow pattern that extends the residence time. The curved geometry naturally guides water flow along a longer path from the center through the filter media to the periphery, maximizing filtration efficiency within a compact volume.
2Volume of moving object
If a disc form filter is used to reduce space occupation, then filter volume is reduced, but filtration depth decreases and residence time is shortened
Solution Approach 1:
The disc-shaped filter incorporates curved radial flow paths that guide water from the center through the filter media to the periphery. This curved geometry creates a naturally extended flow path length, maximizing residence time despite the compact horizontal configuration of the filter.
Solution Approach 2:
The patent extends the filtration path in the radial dimension rather than the vertical dimension. By arranging filter media in a disc configuration with radial flow paths, the system achieves extended residence time through horizontal extension rather than vertical depth, maintaining compact volume while improving filtration efficiency.
3Reliability
If granular filtering material is used to provide adequate filtration life, then filtration efficiency is improved, but the filter becomes bulky and channeling occurs
Solution Approach 1:
The patent employs a composite filter media structure combining multiple materials including activated carbon, ion exchange resin, and other filtering materials in a layered disc configuration. This composite approach provides diverse filtration mechanisms (adsorption, ion exchange, physical filtration) within a compact structure, achieving high filtration efficiency without requiring large volumes of single-material granular media.
Solution Approach 2:
The filter media utilizes porous structured materials including activated carbon and ion exchange resin in a compressed disc form. These porous materials provide extensive surface area for filtration within a compact volume, preventing channeling by maintaining uniform flow distribution through the compressed disc structure rather than loose granular material.

AI summary
The present invention relates to a fluid filter for treating fluid, including a filter media for filtering the fluid, and a filter housing having a fluid impermeable plate to carry the filter media. The fluid outlets and the fluid outlets are arranged in a staggered manner in a height direction of the filter media, so that a flow path along which the fluid flows in the filter media is extended, preferably maximized, to provide an extended fluid residence time. The present invention also discloses a water container comprising the water filter and an air release device for discharge of air remaining in the water filter to an atmosphere.
