Solution Overview

Problem

Existing electronic cigarettes suffer from material waste as the atomizing assembly remains intact when the liquid is exhausted, requiring users to replace the entire cartridge rather than just the liquid reservoir.

Innovation Solution

An electronic atomization device with individually replaceable liquid storage assembly, where the liquid storage assembly is pluggably disposed within the atomizing assembly's housing, allowing for independent replacement of the liquid storage assembly without affecting the atomizing assembly, facilitating space-saving and simple assembly while reducing material waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the cartridge integrating the atomizing assembly and the liquid reservoir is designed as a disposable consumable, then the device is simple to use and manufacture, but material waste increases as the entire cartridge must be replaced even when only the liquid is exhausted

Engineering Contradiction:
Improveease of manufactureVSAvoidmaterial waste
Core Design Contradiction:
Ease of manufactureVSLoss of substance

Solution Approach 1:

The cartridge is divided into separate functional modules: the atomizing assembly and the liquid reservoir are independently replaceable. This allows users to replace only the liquid reservoir when needed, rather than the entire cartridge, thereby reducing material waste while maintaining ease of manufacture through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The design enables selective discarding of only the consumable liquid reservoir portion when liquid is exhausted, while the atomizing assembly is recovered and reused. This partial replacement strategy reduces material waste compared to disposing of the entire cartridge, while maintaining simplicity in the replacement process

Inventive Principle:
Principle #34Discarding and recovering

2Device complexity

If the entire cartridge is replaced when liquid is exhausted, then the device structure is simple, but the atomizing assembly remains intact and causes material waste

Engineering Contradiction:
Improvedevice complexityVSAvoidmaterial waste
Core Design Contradiction:
Device complexityVSLoss of substance

Solution Approach 1:

The cartridge structure is segmented into the atomizing assembly and liquid reservoir as separate replaceable units. This segmentation increases device complexity slightly but enables selective replacement of only the liquid reservoir, reducing material waste from the atomizing assembly while maintaining operational simplicity

Inventive Principle:
Principle #1Segmentation

3Loss of substance

If the liquid storage assembly is made individually replaceable, then material waste is reduced and sustainability is enhanced, but the assembly structure becomes more complex

Engineering Contradiction:
Improvematerial wasteVSAvoiddevice complexity
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The liquid storage assembly is designed as a separable module that can be independently replaced from the atomizing assembly. This segmentation enables reduced material waste by allowing selective replacement of only the liquid reservoir, while the increased device complexity is managed through standardized connection interfaces

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The atomizing assembly is designed as a universal base unit that can work with multiple liquid reservoir replacements. This multi-functionality approach reduces material waste by enabling repeated use of the atomizing assembly while accommodating different liquid reservoir units, balancing the increased assembly complexity with operational versatility

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