Solution Overview

Problem

Existing electronic atomization devices have a simple mechanism for removing the atomization core, which can be easily accessed by children, leading to potential hazards such as accidental ingestion of the substrate.

Innovation Solution

The atomizer design includes a slide cavity within an inner barrel where the atomization core assembly is received, and a mouthpiece assembly that pushes the atomization core assembly to slide within the cavity, allowing the end of the atomization core to be exposed for removal, thus requiring special skills to disassemble.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a simple connection structure is used for the atomization core, then the ease of operation is improved, but the safety for vulnerable people deteriorates

Engineering Contradiction:
Improveease of removing atomization coreVSAvoidhazard to children
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The atomization core assembly is divided into separable components: the atomization core itself and a retaining structure. The retaining structure includes a retention member that engages with the inner barrel through a specific mechanism (such as a snap-fit or interference fit), requiring deliberate action to disengage. This segmentation allows the atomization core to be removed by adults who can perform the required manipulation while preventing accidental removal by children who cannot execute the disengagement sequence.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A retention member acts as an intermediary mechanism between the atomization core and the inner barrel. This intermediary component creates a controlled interface that requires specific manipulation (such as pushing, twisting, or pressing a release mechanism) to disengage. The retention member translates simple user input into the force needed to overcome the retention force, allowing easy removal for adults while presenting a barrier to children.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If the atomization core is easily accessible, then the ease of operation is improved, but the reliability deteriorates

Engineering Contradiction:
Improveease of accessing atomization coreVSAvoidprevention of accidental access
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The retention structure implements preliminary anti-action by pre-establishing a mechanical barrier (retention force) that opposes accidental removal. The retention member is pre-loaded or pre-positioned to engage with the inner barrel, creating an initial resistive force that must be overcome before the atomization core can be removed. This preliminary opposing force prevents unintended access while allowing deliberate removal when the user applies the correct manipulation sequence.

Inventive Principle:
Principle #9Preliminary anti-action

3Object-affected harmful factors

If a complex disassembly mechanism is used, then the safety for vulnerable people is improved, but the device complexity increases

Engineering Contradiction:
Improveprotection from harmful factorsVSAvoidcomplexity of disassembly mechanism
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The retention mechanism is segmented into simple, discrete components (retention member, retention cavity, inner barrel) rather than a complex integrated system. Each component has a single, well-defined function, and their interaction creates the protective effect. This segmentation maintains low device complexity while achieving safety through the cumulative effect of simple mechanical interactions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The complex protective function is localized to a specific region (the retention interface between the retention member and inner barrel) rather than distributed throughout the entire device. The retention mechanism concentrates the safety function at the point where the atomization core interfaces with the inner barrel, keeping the rest of the device simple and maintaining overall low complexity while providing robust protection.

Inventive Principle:
Principle #3Local quality

AI summary

An atomizer (100) includes: a liquid storage assembly (10), including an inner barrel (13), wherein the inner barrel defines a slide cavity (130), the slide cavity is defined for receiving the atomization core assembly (30); and a mouthpiece assembly (20), disposed at an end of the inner barrel (13) for pushing against the atomization core assembly, such that the atomization core assembly slides relative to the inner barrel, and an end of the atomization core assembly is exposed to an outside of the atomizer. By configuring the mouthpiece assembly to push against the atomization core assembly, the atomization core assembly slides along the slide cavity of the inner barrel, and one end of the atomization core assembly is exposed to the outside. Therefore, a risk of children removing the atomization core assembly and causing hazards to themselves may be reduced effectively.
