Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the additional e-liquid tank is in fluid communication with the atomizer, then the service life of the aerosol generating device is extended, but an excessive amount of aerosol generating substrate flows into the atomizer causing the atomization core to be directly immersed

Engineering Contradiction:
Improveservice lifeVSAvoidaerosol generating substrate flow amount
Core Design Contradiction:
Duration of action of moving objectVSQuantity of substance

Solution Approach 1:

The patent introduces a porous plate between the additional e-liquid tank and the atomizer. The porous structure allows controlled passage of aerosol generating substrate through capillary action while limiting excessive flow. This resolves the contradiction by enabling extended service life through supplementation while preventing over-flow that would cause direct immersion of the atomization core.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The porous plate acts as an intermediary component between the additional e-liquid tank and the atomizer. It mediates the flow of aerosol generating substrate, allowing necessary supplementation to extend service life while restricting excessive flow to prevent direct immersion. The intermediary structure balances both requirements.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If an excessive amount of aerosol generating substrate flows into the atomizer, then the atomization core is directly immersed, but this causes deviation from preset concentration requirements and negative impact on user experience

Engineering Contradiction:
Improveaerosol generating substrate availabilityVSAvoidaerosol concentration control
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The porous plate provides controlled substrate flow through its porous structure, regulating the amount of aerosol generating substrate that reaches the atomizer. This maintains preset concentration requirements by preventing excessive flow while ensuring adequate substrate availability for continuous operation.

Inventive Principle:
Principle #31Porous materials

3Manufacturing precision

If the air outlet channel is isolated from the main storage cavity, then aerosol concentration can be maintained, but the structure becomes more complex

Engineering Contradiction:
Improveaerosol concentrationVSAvoidatomizer structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The atomizer structure is segmented into distinct functional zones: the air outlet channel is isolated from the main storage cavity, creating separate pathways for aerosol generation and liquid storage. This segmentation maintains aerosol concentration by preventing direct mixing while organizing complexity into manageable functional modules.

Inventive Principle:
Principle #1Segmentation
