Solution Overview

Problem

Electrostatic atomizing devices face issues with scaling due to high viscosity functional water solutions blocking ejection pins and poor mist ejection performance when switching between different solutions, leading to reduced air deodorizing, sterilization, and freshness maintenance.

Innovation Solution

A disposable capsule with an ejection pin impregnated in a porous medium, sealed with a sealing member and a pressing mechanism to project the ejection pin externally, combined with an electrostatic atomizing device that applies voltage to the ejection pin for efficient mist formation, preventing scaling and solution mixing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the functional water solution has a high viscosity, then the electrostatic atomizing device can maintain solution stability, but the ejection pin which is a porous medium gets blocked causing scaling phenomenon

Engineering Contradiction:

Improvesolution stabilityVSAvoidejection pin blockage

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

The patent extracts the ejection pin from the main device body and places it inside a replaceable capsule. This allows the ejection pin to be easily removed and replaced when blocked, preventing permanent device failure. The capsule can be taken out, the ejection pin extracted, and a new one inserted without disassembling the main device.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the physical state of the ejection pin by providing multiple ejection pins with different pore sizes or materials within the same capsule, or by using a single ejection pin that can be replaced with another having different parameters. This allows optimization for different solution viscosities while maintaining reliability.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the functional water solution is replaced with other kind of functional water solution, then the device can provide different functions, but mixing with previously remained solution causes poorer mist ejection performance

Engineering Contradiction:

Improvesolution type varietyVSAvoidmist ejection performance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the device into a main body and a replaceable capsule containing the functional water solution and ejection pin. This segmentation allows complete replacement of the solution without any mixing with previous solutions, maintaining optimal mist ejection performance for each solution type.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent employs a disposable capsule that is replaced whenever the functional water solution needs to be changed. This eliminates the problem of solution mixing entirely, as each new capsule contains only the new solution without any contamination from previous solutions, ensuring consistent performance.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Duration of action of moving object

If the ejection pin operates over a long time period, then the device can provide continuous mist emission, but the porous medium gets blocked due to high viscosity solution

Engineering Contradiction:

Improvecontinuous operation timeVSAvoidejection pin blockage

Core Design Contradiction:

Duration of action of moving objectVSReliability

Solution Approach 1:

The patent implements a system where the capsule containing the ejection pin is discarded after a certain period of use or when blockage occurs, and replaced with a new capsule. This allows continuous operation of the main device while periodically replacing the consumable ejection pin component, maintaining reliability over long time periods.

Inventive Principle:

Principle #34Discarding and recovering
