Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If e-liquid is refilled to the atomizer, then the atomizer can continue to function, but bubbles are produced and difficult to release, reducing atomization efficiency

Engineering Contradiction:
Improveatomizer operation durationVSAvoidbubble formation
Core Design Contradiction:
Duration of action of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The patent extracts the harmful bubbles from the atomizer chamber through a dedicated bubble discharge structure. The hollow rod with its open lower end and side holes provides a specific pathway for bubbles to escape from the atomization chamber, separating the bubble removal function from the atomization function and preventing bubble-related atomization efficiency degradation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The hollow rod acts as an intermediary structure that facilitates bubble discharge. It provides a controlled pathway between the atomizer chamber and the external environment, allowing bubbles to escape through the side holes without disrupting the atomization process. This intermediary structure mediates between the need to maintain e-liquid levels and the need to eliminate bubbles.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If e-liquid is refilled to the atomizer, then the atomizer can continue to function, but bubbles are difficult to release, affecting vapor production

Engineering Contradiction:
Improvevapor productionVSAvoidbubble blockage
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The bubble discharge structure extracts bubbles from the atomization chamber through the hollow rod's side holes, preventing bubble accumulation that would otherwise block the atomization process. This continuous bubble removal maintains optimal atomization conditions and sustains vapor production efficiency over extended operation periods.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The hollow rod structure enables continuous bubble discharge during atomizer operation. The open lower end and side holes provide ongoing pathways for bubble escape, ensuring that the atomization process remains uninterrupted and vapor production continues efficiently without periodic degradation from bubble blockage.

Inventive Principle:
Principle #20Continuity of useful action

3Ease of operation

If e-liquid is stored in the atomizer, then the atomizer is ready for use, but e-liquid condenses and adheres to the atomizer, adversely affecting atomization efficiency

Engineering Contradiction:
Improveatomizer readinessVSAvoide-liquid condensation
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The cotton pieces positioned at both ends of the hollow rod extract condensed e-liquid from the atomizer chamber. The hydrophilic cotton material absorbs the condensed e-liquid through capillary action, removing it from the atomization area and preventing the condensation-adhesion problem that would otherwise degrade atomization efficiency while maintaining atomizer readiness.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The cotton pieces utilize their porous structure to absorb condensed e-liquid through capillary action. The porous material provides a large surface area for e-liquid absorption, effectively removing condensed liquid from the atomizer chamber and preventing it from adhering to atomization surfaces, thereby maintaining atomization efficiency.

Inventive Principle:
Principle #31Porous materials
