Solution Overview

Problem

Conventional electronic cigarettes suffer from e-liquid leakage and cannot be charged while in use, leading to a poor user experience.

Innovation Solution

The design includes an atomizing assembly that can be unfixedly connected to the battery assembly, allowing the e-cigarette to be charged while in use, with a box assembly that can be opened to facilitate charging and featuring a mechanism to prevent e-liquid leakage by sealing the e-liquid inlet when not in use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the atomizing assembly is fixedly connected to the battery assembly, then the device structure is simple, but e-liquid leakage occurs

Engineering Contradiction:
Improvedevice structureVSAvoide-liquid leakage prevention
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The atomizing assembly is designed to be rotatably connected to the battery assembly rather than fixedly connected. The connection allows the atomizing assembly to rotate between a working position (where e-liquid flows to the atomization unit) and a storage position (where the e-liquid inlet is sealed). This dynamic connection resolves the contradiction by enabling both structural simplicity and leakage prevention through position-based functionality.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If the atomizing assembly is fixedly connected to the battery assembly, then the device structure is simple, but charging during use is not possible

Engineering Contradiction:
Improvedevice structureVSAvoidcharging capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The rotatable connection enables the device to adapt between different usage states. The atomizing assembly can be rotated to a storage position that exposes charging terminals, allowing charging during use. This dynamic configuration resolves the contradiction by providing both structural simplicity and charging adaptability.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the e-liquid inlet is exposed when not in use, then the device is easy to operate, but e-liquid leakage occurs

Engineering Contradiction:
Improvedevice operationVSAvoide-liquid leakage prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The device automatically transitions the e-liquid inlet between exposed and sealed states through rotation. When stored, the inlet is sealed to prevent leakage; when used, it rotates to expose the inlet for e-liquid flow. This dynamic state change resolves the contradiction without requiring manual intervention, maintaining ease of operation while preventing leakage.

Inventive Principle:
Principle #15Dynamics

4Reliability

If a sealing mechanism is added to prevent e-liquid leakage, then e-liquid leakage is prevented, but device complexity increases

Engineering Contradiction:
Improvee-liquid leakage preventionVSAvoiddevice structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Instead of adding complex sealing mechanisms, the patent uses the rotational movement of the atomizing assembly itself to achieve sealing. The seal ring and seal plug are integrated into the existing rotatable structure, allowing leakage prevention through position-based sealing rather than additional complex components. This resolves the contradiction by maintaining reliability while minimizing complexity.

Inventive Principle:
Principle #15Dynamics
