Solution Overview

Problem

Conventional electronic cigarettes face issues with e-liquid condensate accumulation and potential short circuits due to inadequate air conduction and sealing mechanisms, which affect the performance and safety of the device.

Innovation Solution

The proposed atomization assembly incorporates a U-shaped ceramic core with inert cotton for e-liquid condensate absorption, an air admission assembly with a silicone seat and air duct for sealing, and a sieve-shaped air vent in the battery assembly to prevent short circuits by isolating condensate, along with a magnetic connection between the atomizer and battery assembly for secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional air conduction mechanisms are used, then air flow is maintained, but e-liquid condensate accumulates causing short circuits

Engineering Contradiction:
Improveprevention of short circuitsVSAvoide-liquid condensate accumulation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the harmful condensate from the air conduction path by introducing a separate absorption system. The inert cotton absorbs e-liquid condensate away from the air conduction column, preventing it from causing short circuits while maintaining air flow through the original path.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The inert cotton acts as an intermediary substance between the air conduction path and the condensate. It absorbs the harmful condensate without interfering with the air flow, effectively mediating between the conflicting requirements of air conduction and condensate management.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If ceramic core with cotton string is used for e-liquid adsorption, then e-liquid handling is improved, but condensate absorption capacity is insufficient

Engineering Contradiction:
Improvee-liquid handlingVSAvoidcondensate absorption capacity
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent merges two absorption systems: the ceramic core with cotton string for e-liquid adsorption, and the inert cotton for condensate absorption. This combination allows the system to handle both e-liquid and condensate effectively, addressing the insufficient condensate absorption capacity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Different materials are assigned to different locations based on their specific functions: cotton string in the ceramic core for e-liquid adsorption, and inert cotton in the air conduction path for condensate absorption. This local differentiation optimizes the performance of each component for its specific purpose.

Inventive Principle:
Principle #3Local quality

3Reliability

If air duct passes through silicone seat for sealing, then sealing is improved, but air conduction path complexity increases

Engineering Contradiction:
Improvesealing performanceVSAvoidair conduction path structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The silicone seat serves multiple functions: it provides sealing between the air duct and the housing, and simultaneously acts as a mounting structure for the air duct. This multi-functionality reduces the need for additional sealing components, simplifying the overall structure despite the air duct passing through it.

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