Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the atomizer atomizes cigarette liquid continuously, then the atomization function is maintained, but negative pressure is generated in the liquid cavity causing obstructed liquid flow

Engineering Contradiction:
Improveatomization continuityVSAvoidliquid flow smoothness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

An air exchange plug is introduced as an intermediary component in the air flow channel. This plug with micropores allows air to penetrate through while regulating the air-liquid interaction, preventing excessive negative pressure buildup in the liquid cavity and ensuring smooth continuous liquid flow during atomization

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The air exchange plug is designed with a porous structure containing micropores. This porous material allows controlled air penetration through the plug into the liquid cavity, enabling pressure balance and preventing liquid flow obstruction while maintaining atomization continuity

Inventive Principle:
Principle #31Porous materials

2Productivity

If negative pressure is generated in the liquid cavity to facilitate atomization, then atomization efficiency is improved, but liquid flow becomes obstructed generating burnt flavor

Engineering Contradiction:
Improveatomization efficiencyVSAvoidburnt flavor
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The air exchange plug acts as a mediator between the air flow channel and liquid cavity. It allows controlled air penetration through its microporous structure to balance pressure, preventing excessive negative pressure that would cause liquid obstruction and burnt flavor while maintaining sufficient atomization efficiency

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The microporous structure of the air exchange plug changes the pressure parameters within the liquid cavity by allowing controlled air ingress. This modifies the pressure distribution to prevent excessive negative pressure buildup, eliminating burnt flavor caused by liquid flow obstruction while preserving atomization efficiency

Inventive Principle:
Principle #35Parameter changes
