Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Electronic cigarettes with tobacco liquid face issues of tobacco leakage, which affects the heating effect and is not adequately addressed by existing methods that only prevent external leakage without preventing internal leakage into the atomizer.

Innovation Solution

An atomizer design featuring a liquid storage chamber with a heating component that includes a heating element and a liquid storage sump, where the heating element is positioned below a liquid conductive hole, allowing tobacco liquid to flow for atomization and storing any leaking liquid in the sump to prevent it from entering the air pipe.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If tobacco liquid is stored in a liquid storage chamber with a liquid conducting hole, then the heating element can atomize the tobacco liquid, but the tobacco liquid may leak into the atomizer's air passage

Engineering Contradiction:

Improveatomization efficiencyVSAvoidtobacco liquid leakage into air passage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a liquid storage sump as an intermediary component between the liquid storage chamber and the heating element. This sump acts as a buffer zone that collects any tobacco liquid that leaks from the heating element, preventing it from entering the air passage. The sump serves as a mediator that handles the harmful leakage while allowing the main atomization function to continue operating.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent converts the harmful effect of tobacco liquid leakage into a beneficial function by designing the liquid storage sump to not only collect leaked liquid but also to provide additional atomization surface area. The leaked liquid that would otherwise be wasted or harmful is instead stored in the sump and continuously atomized by the heating element, turning a negative phenomenon into a useful feature that enhances vapor production.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Speed

If the heating element is positioned under the liquid storage chamber, then tobacco liquid can flow directly to the heating element for atomization, but leaked liquid cannot be contained

Engineering Contradiction:

Improveliquid flow speed to heating elementVSAvoidleakage containment

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The patent segments the liquid containment space into two distinct zones: the liquid storage chamber for holding the main liquid supply and the liquid storage sump for collecting leaked liquid. This segmentation allows the system to maintain rapid liquid flow to the heating element while providing a dedicated containment zone for any leakage, thus resolving the contradiction between flow speed and leakage containment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies preliminary anti-action by pre-positioning the liquid storage sump below the heating element in anticipation of potential leakage. This preventive measure ensures that any liquid that leaks during operation is immediately captured by the sump before it can enter the air passage, thus preventing the harmful effect before it occurs.

Inventive Principle:

Principle #9Preliminary anti-action
