Solution Overview

Problem

Existing media purification devices face inefficiencies in maximizing the utilization of purification media, leading to reduced effectiveness and increased maintenance challenges due to gaps forming between the media and the tank, which affects the length of contact and distribution of water.

Innovation Solution

The integration of a flow controller within the porous container of the purification media device, which can be elastic or non-elastic, provides additional back pressure and flow restrictions, maintaining the controller perpendicular to the primary flow axis, and is made from materials like polypropylene or stainless steel, to enhance media utilization and prevent gaps from forming.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a flow controller is integrated within the porous container, then media utilization is maximized and gap formation is prevented, but device complexity increases

Engineering Contradiction:
Improvemedia utilizationVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The flow controller is merged with the porous container by forming it as an integral part of the container structure, specifically as a reduced porosity region or embedded component within the container walls. This integration eliminates the need for separate flow controller components while maintaining the flow control function, thus maximizing media utilization without proportionally increasing device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The porous container is designed to serve multiple functions: it contains the purification media, provides structural support, and incorporates flow control capabilities through its reduced porosity regions or integrated flow controller. This multi-functionality allows a single component to address multiple requirements (containment, support, and flow regulation), improving media utilization while minimizing the addition of separate components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If additional back pressure and flow restrictions are provided, then media utilization is enhanced, but manufacturing complexity increases

Engineering Contradiction:
Improvemedia utilizationVSAvoidmanufacturing complexity
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

Instead of making the entire porous container have uniform flow restriction properties, the invention applies local quality by creating reduced porosity regions or flow controller structures at specific locations within the container (e.g., at the inlet or outlet ends). This localized approach provides the necessary back pressure and flow restrictions to enhance media utilization while keeping the manufacturing process simpler than if the entire structure required complex flow control features.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If the flow controller is positioned at the bottom or top interior surface, then water distribution is enhanced, but device complexity increases

Engineering Contradiction:
Improvewater distributionVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The flow controller is merged with the container structure by forming it as an integral part of the interior surface, either at the bottom or top of the porous container. This integration allows the flow controller to enhance water distribution across the purification media while avoiding the need for separate, movable, or complex positioning mechanisms, thus improving ease of operation without proportionally increasing device complexity.

Inventive Principle:
Principle #5Merging (Combining)
