Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If a cylindrical atomization core with a central through hole is used, then the atomization core can be elongated and have a circular tube-like structure, but aerosol-forming material accumulates in the through hole causing clogging and leakage

Engineering Contradiction:

Improvecircular tube-like structureVSAvoidclogging and leakage

Core Design Contradiction:

ShapeVSReliability

Solution Approach 1:

The central through hole is segmented into multiple air outlet channels by the blocking member, transforming a single continuous space into multiple separated flow paths. This segmentation prevents material accumulation and clogging while maintaining the circular tube-like external structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The blocking member acts as an intermediary element within the through hole, creating air outlet channels that mediate between the liquid guiding element and the external environment. This intermediary structure enables controlled aerosol ejection while preventing direct contact and accumulation in a single open space.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If a central through hole is used in the atomization core, then the structure is simple and manufacturing is easy, but condensate backflows into the through hole causing secondary atomization

Engineering Contradiction:

Improvesimple structureVSAvoidcondensate backflow and secondary atomization

Core Design Contradiction:

Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The through hole is divided into multiple separate air outlet channels by the blocking member, creating isolated ejection paths. This segmentation prevents condensate from flowing back into a single open space and undergoing secondary atomization, while maintaining manufacturing simplicity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of allowing a single open through hole for aerosol ejection, the invention inverts the approach by creating multiple closed air outlet channels within the blocking member. This inverted structure prevents condensate backflow while maintaining ease of manufacture through simple geometric modifications.

Inventive Principle:

Principle #13The other way round (Inversion)

3Reliability

If the porosity of the blocking member is reduced to prevent material penetration, then clogging is reduced, but aerosol flow resistance increases

Engineering Contradiction:

Improveprevention of material penetrationVSAvoidaerosol flow resistance

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The blocking member utilizes porous material properties with controlled porosity to achieve a balance between preventing aerosol-forming material penetration and allowing smooth aerosol flow. The porous structure provides filtration functionality while minimizing flow resistance through optimized pore distribution and size.

Inventive Principle:

Principle #31Porous materials
