Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a porous ceramic vaporization core is used, then the device structure is simple, but heat and mass transfer efficiency is low and e-liquid explosion occurs

Engineering Contradiction:

Improvevaporization core structureVSAvoidheat and mass transfer efficiency

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The porous body is divided into multiple unit layers with alternating liquid storage advantage layers and liquid locking advantage layers. This segmentation creates a layered structure that improves heat and mass transfer efficiency while preventing e-liquid explosion, resolving the contradiction between structural simplicity and transfer efficiency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different layers of the porous body are assigned different functions: liquid storage advantage layers for rapid liquid supply and liquid locking advantage layers for controlling liquid release. The heating film is selectively combined with the liquid locking advantage layer surface and partially infiltrates it, creating local quality variations that optimize both transfer efficiency and reliability.

Inventive Principle:

Principle #3Local quality

2Reliability

If the heating film fully infiltrates the porous body, then heat transfer is improved, but e-liquid explosion risk increases

Engineering Contradiction:

Improveheat transfer efficiencyVSAvoide-liquid explosion risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The heating film partially infiltrates the liquid locking advantage layer rather than fully infiltrating the entire porous body. This partial action provides sufficient heat transfer efficiency while avoiding excessive infiltration that would cause e-liquid explosion, thus resolving the contradiction between heat transfer improvement and explosion risk.

Inventive Principle:

Principle #16Partial or excessive action

3Productivity

If liquid supply speed is increased, then vaporization efficiency is improved, but e-liquid explosion likelihood increases

Engineering Contradiction:

Improvevaporization efficiencyVSAvoide-liquid explosion likelihood

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The liquid supply function is segmented between liquid storage advantage layers (for rapid supply) and liquid locking advantage layers (for controlled release). This segmentation enables high vaporization efficiency while preventing e-liquid explosion through coordinated liquid supply and release mechanisms.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The porous body parameters (porosity, pore size distribution) are optimized in different layers to control liquid supply speed and release characteristics. By changing these parameters across layers, the system achieves high vaporization efficiency while maintaining reliability and preventing e-liquid explosion.

Inventive Principle:

Principle #35Parameter changes
