Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the atomizer operates continuously to atomize liquid, then the atomization function is maintained, but negative pressure builds up in the liquid cavity causing obstructed liquid flow and burnt flavor

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

Solution Approach 1:

The sealing member acts as an intermediary component between the tube wall and heating assembly. It introduces an air guiding channel that mediates the pressure balance by allowing controlled air intake into the liquid cavity, preventing negative pressure buildup while maintaining liquid flow smoothness and atomization continuity

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention utilizes pneumatic principles by introducing air into the liquid cavity through the air guiding channel defined by the sealing member. This air intake compensates for the negative pressure generated during continuous liquid consumption, maintaining pressure balance and preventing obstructed flow without affecting atomization performance

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Reliability

If the sealing member is added to achieve airtightness, then sealing performance is improved, but the structure becomes more complex

Engineering Contradiction:
ImproveairtightnessVSAvoidatomizer structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sealing member performs multiple functions simultaneously: it provides sealing between the tube wall and heating assembly, defines the air guiding channel for pressure balance, and maintains structural integrity. This multi-functionality achieves reliable airtightness while minimizing the addition of separate components, thus limiting the increase in structural complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)
