Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the atomization electrode base is spaced apart from the housing to prevent heat conduction, then cooling efficiency is improved, but condensed water accumulates on the exposed base surface causing discharging instability

Engineering Contradiction:
Improvecooling efficiencyVSAvoiddischarging stability
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The base of the atomization electrode is divided into a heat-conductive portion (contacting the partition plate) and a heat-nonconductive portion (exposed to air). This segmentation allows different parts of the base to serve different functions: one part manages heat dissipation while the other allows controlled condensed water collection without compromising overall cooling efficiency or discharging stability.

Inventive Principle:
Principle #1Segmentation

2Strength

If the atomization electrode base contacts the housing for structural support, then mechanical stability is improved, but cooling efficiency decreases due to heat conduction

Engineering Contradiction:

Core Design Contradiction:
StrengthVSTemperature

Solution Approach 1:

The base is segmented into distinct functional zones: a heat-conductive portion that contacts the partition plate for mechanical support and heat dissipation, and a heat-nonconductive portion that remains exposed for controlled condensed water management. This segmentation resolves the contradiction by allowing mechanical stability through controlled contact while minimizing unwanted heat conduction.

Inventive Principle:
Principle #1Segmentation

3Reliability

If the partition plate completely seals the base region to prevent water accumulation, then discharging stability is improved, but cooling efficiency decreases due to trapped heat

Engineering Contradiction:
Improvedischarging stabilityVSAvoidcooling efficiency
Core Design Contradiction:
ReliabilityVSTemperature

Solution Approach 1:

The partition plate configuration creates a segmented space where the base region is partially enclosed to prevent water accumulation but not completely sealed. This allows controlled heat dissipation while maintaining discharging stability by preventing condensed water from reaching the discharge tip.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the base are given different thermal properties: the portion contacting the partition plate is heat-conductive for support and controlled heat dissipation, while the exposed portion is heat-nonconductive to allow condensed water collection. This local differentiation resolves the contradiction between sealing for stability and leaving open for cooling.

AI summary

An electrostatic atomization device that prevents the cooling capability from being lowered due to contact of an atomization electrode with another ember, while effectively preventing surplus production of condensed water that would destabilize discharging at the distal end of the atomization electrode. the electrostatic atomization device includes an atomization electrode having a cylindrical electrode body and a base which is informed at a basal end of the electrode body and has a larger diameter than the electrode from the base to produce condensed water on the atomization electrode. Voltage is applied to the atomization electrode when the condensed water is produced to generate charged fine water droplets. A partition plate includes an insertion hole that receives the electrode body of the atomization electrode. The partition plate and the base of the atomization electrode form a water collection region in between.
