Solution Overview

Problem

Condensate generated during atomization in electronic atomization devices flows into the power supply structure, causing corrosion and damage to electrical components.

Innovation Solution

An air inlet channel is formed between the atomizer and the power supply structure, allowing external airflow to mix with aerosol without passing through the power supply structure, preventing condensate from entering and protecting electrical components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If external airflow enters from the bottom of the power supply structure and flows through the battery and motherboard to the atomizer, then the atomization process can be supported, but condensate generated during atomization flows onto the motherboard causing corrosion and damage

Engineering Contradiction:
Improveatomization functionVSAvoidpower supply structure reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The air inlet channel is segmented into two separate paths: one for air intake and one for condensate drainage. The air inlet channel is defined between the atomizer and the power supply structure, while the condensate drainage channel is defined between the atomizer and the battery, preventing condensate from reaching the motherboard.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The condensate drainage function is extracted from the air inlet channel and assigned to a separate channel. The condensate drainage channel is specifically designed to carry condensate away from the atomizer to the battery, separating this harmful substance transport from the useful air intake function.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If air inlet channel flows through the interior of the power supply structure, then air can reach the atomizer, but condensate can flow into the power supply structure and corrode electrical components

Engineering Contradiction:
Improveairflow delivery to atomizerVSAvoidcondensate corrosion
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A separate condensate drainage channel acts as an intermediary pathway for condensate removal. This dedicated channel prevents direct contact between condensate and the power supply structure's electrical components, while still allowing the air inlet channel to deliver air through the power supply structure for atomizer operation.

Inventive Principle:
Principle #24Intermediary (Mediator)
