Existing electronic cigarette atomizing devices generate large liquid particles when tobacco liquid is boiled, leading to unsatisfactory user experience due to inefficient atomization.

Innovation Solution

A spraying atomizing device with a housing, liquid tank, heating element, and power supply, featuring an atomizing chamber, a receiving chamber, and a spraying device that sprays tobacco liquid into the chamber, where the heating element converts liquid particles into aerosol, with a circulatory system to enhance atomization efficiency and prevent leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If tobacco liquid is boiled using a heating wire, then the liquid can be atomized, but large liquid particles are generated leading to unsatisfactory user experience

Engineering Contradiction:
Improveatomization qualityVSAvoidlarge liquid particles
Core Design Contradiction:
Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The atomization process is divided into two stages: first, a spraying device breaks the tobacco liquid into small liquid particles; second, a heating element vaporizes these particles. This segmentation prevents direct boiling that creates large particles, achieving finer atomization quality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The spraying device acts as an intermediary between the liquid tank and the heating element. It transforms the liquid from a continuous phase into dispersed particles before they reach the heating element, enabling more efficient and uniform vaporization without generating large particles.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If a spraying device is added to improve atomization, then atomization efficiency improves, but device complexity increases

Engineering Contradiction:
Improveatomization efficiencyVSAvoiddevice structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The spraying device and heating element are integrated into a unified atomization system where the spraying device is positioned above the heating element. This merging allows the two functions to work cooperatively in a compact arrangement, improving atomization efficiency while controlling device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The heating element serves dual functions: it heats the liquid particles for vaporization and also acts as a support structure for the spraying device. This multi-functionality reduces the number of separate components needed, balancing improved atomization efficiency with manageable device complexity.

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

3Manufacturing precision

If liquid particles are sprayed into the atomizing chamber, then atomization is enhanced, but unatomized liquid may leak

Engineering Contradiction:
Improveatomization qualityVSAvoidliquid leakage
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The unatomized liquid particles that would normally be considered waste or a leakage problem are redirected through a receiving chamber back to the liquid tank. This converts the potential harm of leakage into a beneficial recirculation system that maintains liquid levels and prevents actual leakage.

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

Solution Approach 2:

The receiving chamber creates a feedback loop where unatomized liquid is collected and returned to the liquid tank. This feedback mechanism ensures that liquid is continuously recirculated through the atomization process, preventing leakage while maintaining consistent atomization quality.

Inventive Principle:
Principle #23Feedback
