Solution Overview

Problem

Conventional electronic cigarettes have an integrated atomization assembly that is difficult to separate from the battery assembly, and e-liquid tends to leak out when replacing the atomizer, limiting user convenience and extending service life.

Innovation Solution

The atomization assembly includes an e-liquid tank, connector, seal ring, spring, first fixed ring, silicone seal, and base, with an elastic sealing device that prevents e-liquid leakage, and is designed to separate from the battery assembly by rotating the base 90°, allowing for easy atomizer replacement and airflow adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the atomization assembly is integrated with the battery assembly, then the structural stability is improved, but the ease of replacement deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of replacement
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The electronic cigarette is divided into two independent modules: the atomization assembly and the battery assembly. The atomization assembly includes the e-liquid tank, connector, seal ring, spring, first fixed ring, atomizer, silicone seal, silicone plug, and base. The battery assembly includes the battery, control panel, airflow regulation ring, and surface cover. These modules can be separated and reconnected through the base rotation mechanism, allowing easy replacement while maintaining structural integrity when assembled.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If the atomizer is easily replaceable, then the ease of operation is improved, but the e-liquid leakage deteriorates

Engineering Contradiction:
Improveease of replacementVSAvoide-liquid leakage
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The seal ring is pre-installed on the connector before assembly. The spring is pre-positioned to automatically push the seal ring against the e-liquid inlet when the atomizer is inserted. This preliminary preparation ensures that sealing components are in place before operation, preventing e-liquid leakage during replacement.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The seal ring acts as an intermediary sealing element between the connector and the e-liquid inlet. The spring provides elastic force to maintain continuous contact between the seal ring and the inlet surface. This intermediary mechanism ensures reliable sealing during atomizer replacement without requiring disassembly of sealing components.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Duration of action of moving object

If the e-liquid tank volume is increased, then the service life is improved, but the device complexity deteriorates

Engineering Contradiction:
Improveservice lifeVSAvoiddevice complexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The base serves multiple functions: it connects the atomization assembly to the battery assembly, provides a rotation mechanism for easy separation, and houses the seal ring and spring assembly. The first fixed ring also serves as both a structural connector and a mounting platform for the atomizer. This multi-functionality reduces the need for additional components, maintaining simplicity despite the larger e-liquid tank volume.

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