Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the atomizing component directly contacts the non-atomized atomizing medium in the liquid-storing chamber, then the heating and atomization process can be simplified, but the heat energy will transfer to the non-atomized medium causing deterioration

Engineering Contradiction:

Improveatomization structureVSAvoidheat transfer to medium

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The atomizing component is segmented into a heating element and an atomizing portion made of porous material. The heating element is embedded in the porous atomizing portion, creating distinct functional zones that prevent direct heat transfer to the liquid medium while maintaining efficient atomization.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The porous atomizing portion acts as an intermediary between the heating element and the atomizing medium. It receives heat from the embedded heating element and transfers the atomized medium to the liquid-storing chamber, preventing direct contact between the heat source and the non-atomized medium.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If the atomizing portion is placed close to the liquid-storing chamber for efficient atomization, then the atomization process is enhanced, but the non-atomized medium is exposed to high temperature causing deterioration

Engineering Contradiction:

Improveatomization efficiencyVSAvoidtemperature of non-atomized medium

Core Design Contradiction:

ProductivityVSTemperature

Solution Approach 1:

The porous atomizing portion has localized heat absorption and atomization properties. The heating element is embedded only in the atomizing portion, not in the liquid-storing chamber, creating a localized high-temperature zone that enhances atomization efficiency without heating the bulk medium.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The atomizing portion is made of porous material that allows controlled heat penetration and medium absorption. The porous structure enables efficient heat transfer to the atomizing medium while the material's thermal properties prevent excessive heat transfer to the surrounding non-atomized medium.

Inventive Principle:

Principle #31Porous materials

3Reliability

If a liquid guiding portion is added to deliver the atomizing medium, then the delivery stability is improved, but the device complexity increases

Engineering Contradiction:

Improvedelivery stabilityVSAvoidstructural complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The liquid guiding portion is merged with the atomizing portion to form an integrated atomizing core assembly. This combination provides stable liquid delivery while avoiding the complexity of separate guiding mechanisms, as the porous structure itself guides the liquid from the heating element to the atomization interface.

Inventive Principle:

Principle #5Merging (Combining)
