Solution Overview

Problem

Conventional methods for increasing oxygen concentration in oxygen-deficient water areas face challenges such as inefficient oxygen distribution, agitation of bottom materials leading to reduced oxygen concentration, and increased equipment costs due to the need for high-pressure tanks and pressure control systems, which can worsen water pollution and require complex apparatus.

Innovation Solution

A gas-liquid dissolving apparatus that uses a nozzle to eject a gas-liquid multi-phase fluid into a chamber with a dome-shaped top plate, creating a turbulent flow that enhances gas dissolution into water while separating bubbles from the liquid, allowing for continuous, bubble-free high oxygen concentration water supply without excessive pressure, thus preventing bottom material agitation and reducing equipment complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If high-pressure tanks and pressure control systems are used to dissolve oxygen into water, then dissolved oxygen concentration is improved, but device complexity increases

Engineering Contradiction:
Improvedissolved oxygen concentrationVSAvoidequipment complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The apparatus is divided into multiple functional chambers: a dissolving chamber for oxygen dissolution, a separating chamber for gas-liquid separation, and a bottom material layer for filtration. This segmentation allows each component to perform its specific function efficiently without requiring complex high-pressure systems throughout the entire apparatus.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The bottom material layer serves dual purposes: it filters the water and simultaneously provides a surface for oxygen dissolution. The natural buoyancy of bubbles and density differences enable automatic gas-liquid separation without mechanical separators. This self-service approach eliminates the need for complex pressure control systems and high-pressure tanks.

Inventive Principle:
Principle #25Self-service

2Quantity of substance

If bubbled oxygen is directly supplied to oxygen-deficient water area, then dissolved oxygen concentration is improved, but bottom materials are agitated causing harmful effects

Engineering Contradiction:
Improvedissolved oxygen concentrationVSAvoidbottom material agitation
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

Oxygen dissolution is performed in advance in the dissolving chamber before the water is returned to the oxygen-deficient area. This preliminary action ensures that oxygen is already dissolved in the water, eliminating the need for direct bubbling that would agitate bottom materials in the target area.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The bottom material layer acts as an intermediary medium that facilitates oxygen dissolution without direct contact between bubbles and the oxygen-deficient water area. The separator chamber serves as another intermediary, preventing bubbles from reaching the bottom materials in the target area while still delivering oxygen-rich water.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Quantity of substance

If bubbles are present in supplied water, then oxygen dissolution is enhanced, but water quality deteriorates due to bubble contamination

Engineering Contradiction:
Improvedissolved oxygen concentrationVSAvoidwater quality
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The apparatus separates the dissolving function from the delivery function using distinct chambers. The dissolving chamber allows vigorous bubble formation for efficient oxygen transfer, while the separating chamber removes bubbles before water delivery, ensuring high-quality bubble-free water is returned to the oxygen-deficient area.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The separator chamber creates a copy of the dissolution process environment with controlled conditions. By replicating the dissolution mechanism in a separate chamber, the system achieves both efficient oxygen transfer and clean water delivery without compromising either function.

Inventive Principle:
Principle #26Copying
