Solution Overview

Problem

Existing methods for producing ionization rods do not effectively concentrate ions in indoor air to neutralize or eliminate electrostatic charges, which is crucial for improving air quality and reducing pollution in sensitive environments such as electronics manufacturing and animal husbandry.

Innovation Solution

The method involves placing ionization rods in a manner that air flows over them, creating a concentration of more than 1000 ions per cubic centimeter of indoor air. This is achieved by optimizing the airflow through the module, with the ion rods positioned to ensure effective exposure of the carbon fiber brush ends to the airflow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If ionization rods are placed in ventilation ducts to generate ions, then air passing the rods carries free ions, but the ion concentration in indoor air remains insufficient to effectively neutralize electrostatic charges

Engineering Contradiction:
Improveion concentrationVSAvoideffectiveness of charge neutralization
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The ionization system is divided into multiple separate ionization rods distributed throughout the indoor space rather than concentrated in ventilation ducts. This segmentation allows ions to be generated at multiple locations, increasing the overall ion concentration and effectiveness of charge neutralization throughout the entire space.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Carbon fiber brush ends are used as intermediaries to transfer electrical charges from the main lines of the ionization rods to the surrounding air. The brush ends are exposed to air streams that draw charges from the brush ends, facilitating more effective ion release and increasing ion concentration in the indoor air.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If brush deflections are made from main lines to expose ends to air stream, then charges are facilitated to be drawn from brush ends, but the structure becomes more complex

Engineering Contradiction:
Improvecharge emission efficiencyVSAvoidrod structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The carbon fiber brush ends automatically interact with the air stream to facilitate charge emission. The structure uses the natural flow of air to draw charges from the brush ends without requiring additional active components or complex control mechanisms, achieving efficient charge emission while maintaining structural simplicity.

Inventive Principle:
Principle #25Self-service

3Quantity of substance

If multiple ionization rods are separately placed throughout the space, then ion concentration increases to more than 1000 ions per cubic centimeter, but the manufacturing and installation process becomes more complex

Engineering Contradiction:
Improveion concentrationVSAvoidinstallation complexity
Core Design Contradiction:
Quantity of substanceVSEase of manufacture

Solution Approach 1:

The system uses multiple separately placed ionization rods distributed throughout the indoor space, each generating ions locally. This segmentation approach increases the overall ion concentration to more than 1000 ions per cubic centimeter by creating multiple ion generation zones rather than relying on a single centralized source.

Inventive Principle:
Principle #1Segmentation
