Solution Overview

Problem

Conventional water aeration systems rely on energy-consuming machinery like pumps and compressors, which are inefficient, noisy, and costly, and fail to effectively distribute oxygen in deep water bodies, posing economic and environmental challenges.

Innovation Solution

A water aeration system utilizing natural hydrostatic pressure and differential pressure to mix atmospheric oxygen with water, creating turbulence and circulating aerated water across a paddlewheel to enhance oxygen absorption, eliminating the need for energy-consuming machinery and reducing maintenance costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If pumps and compressors are used to aerate water, then oxygen can be introduced into the water, but energy consumption increases and operating costs rise

Engineering Contradiction:
Improveoxygen introduced into waterVSAvoidenergy consumption
Core Design Contradiction:
Quantity of substanceVSUse of energy by moving object

Solution Approach 1:

The system uses the water's own flow and pressure to draw in air through the venturi effect, eliminating the need for external compressors or pumps. The water flow itself creates the suction that mixes air with the water, making the system self-service and energy-efficient

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The invention employs the venturi effect, a pneumatic principle, where water flowing through a constricted passage creates a pressure differential that draws air into the water stream. This hydraulic-pneumatic interaction naturally mixes oxygen with water without requiring mechanical compression equipment

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Quantity of substance

If air compressors are used to provide high pressure air, then air can be forced into water, but the volume of air introduced is limited and costs increase

Engineering Contradiction:
Improvevolume of air introducedVSAvoidaeration efficiency
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The venturi-based system leverages the kinetic energy of flowing water to create a vacuum that actively draws in large volumes of ambient air. This pneumatic-hydraulic coupling allows continuous air intake at atmospheric pressure, dramatically increasing the volume of air processed compared to compressor-based systems

Inventive Principle:
Principle #29Pneumatics and hydraulics

3Quantity of substance

If spargers and propeller agitators are used to aerate deep water, then oxygen can be distributed, but power requirements increase to overcome hydraulic head

Engineering Contradiction:
Improveoxygen distribution in waterVSAvoidpower requirements
Core Design Contradiction:
Quantity of substanceVSPower

Solution Approach 1:

The system utilizes the existing hydraulic head and water flow to drive the aeration process. Water flowing downward through the venturi structures creates the suction needed to draw air in, and the aerated water continues its natural flow path to the collection area, requiring no additional power input

Inventive Principle:
Principle #25Self-service

4Quantity of substance

If conventional aeration systems are installed, then oxygen can be supplied, but maintenance costs and component breakdown risk increase

Engineering Contradiction:
Improveoxygen supply to waterVSAvoidsystem reliability
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The invention extracts and eliminates the problematic mechanical components (compressors, pumps, motors, moving parts) from the aeration system. By relying solely on passive venturi structures and natural water flow, the system removes sources of wear, breakdown, and maintenance requirements while maintaining effective oxygen supply

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An aeration pool or tank has a bottom piping assembly with an inlet at the bottom thereof and an outlet remote from the tank a distance vertically below the inlet, and an air inlet piping assembly having an inlet above the water surface and an outlet within the tank adjacent to the inlet of the bottom piping assembly. Water under pressure flows from the tank by gravity through the bottom piping assembly and draws air through the air inlet piping assembly, mixing it with the exiting water and the aerated water flows into a second body of water across a paddlewheel to disburse the aerated water into the second body of water and create circulation to absorb additional oxygen at the surface of the second body of water. A water circulation piping assembly in the tank creates turbulence and circulation within in the water in the tank.
