Solution Overview

Problem

Existing filter-as-you-fill systems are inefficient in contaminant removal, often requiring several minutes for water to be filtered and can result in fluid bypass, leading to consumption of unfiltered water due to improper seating of filter media within the housing.

Innovation Solution

A filter assembly with a housing featuring a frame and optional casing, where the filter media is secured in a partially curved configuration, utilizing gravitational force for filtration, achieving faster contaminant removal with less media than alternative systems and preventing fluid bypass.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If filter media is placed in traditional flat configuration within filter housing, then filtration function is provided, but fluid bypass occurs due to improper seating resulting in consumption of unfiltered water

Engineering Contradiction:
Improvefiltration reliabilityVSAvoidfluid bypass
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The filter media is configured in a curved or cylindrical shape that conforms to the curved inner surface of the filter housing, ensuring proper seating and contact between the filter media and housing walls. This curved configuration eliminates gaps and prevents fluid bypass while maintaining effective filtration across the entire water flow path.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Productivity

If traditional filter as you fill systems are used, then filtration is achieved, but filtration time is several minutes which is inefficient

Engineering Contradiction:
Improvefiltration speedVSAvoidfiltration time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The filter media transitions from a traditional flat two-dimensional configuration to a curved three-dimensional cylindrical configuration. This dimensional change increases the effective surface area of the filter media in contact with water, allowing faster filtration throughput while maintaining contaminant removal efficiency.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If more filter media is used to ensure proper filtration, then contaminant removal improves, but device complexity and media quantity increase

Engineering Contradiction:
Improvecontaminant removal efficiencyVSAvoidfilter media quantity
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The curved cylindrical configuration of the filter media maximizes the use of available space within the filter housing, allowing the filter media to conform to the housing geometry and utilize the full volume efficiently. This configuration achieves effective contaminant removal with optimized media quantity by eliminating wasted space and ensuring complete water-media contact.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

A filter housing can be configured to receive a filter media to form a filter assembly. Water filter media assemblies can be adapted for filter-as-you-pour filtration in the context of container (e.g., pitcher) systems where filtering is achieved as the user pours water from the container. The filter housing can have a frame and an optional casing securable about the frame. The filter assembly can include a filter media within, connected to, or associated with a filter housing. The filter media can be securable in an at least partially curved configuration and/or within, connected to, or associated with the filter housing.
