Solution Overview

Problem

Existing atomizers with cotton-wrapped heating structures face issues such as liquid leakage, uneven heating, and difficulty in achieving effective atomization, which can lead to inhaling the liquid by mistake and affect the smell and/or taste of the vapor.

Innovation Solution

A novel heat generating body with a ceramic body and embedded auxiliary heat generating wires on its outer surfaces, which provides even heating and reduces the risk of liquid leakage, combined with an atomizer design that includes a suction nozzle and a liquid storage assembly for efficient vaporization and separation of liquid and smoke.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cotton-wrapped heating method is used, then liquid can be heated, but liquid leakage occurs and wrapped cotton may be scorched due to uneven heating

Engineering Contradiction:

Improveliquid leakage preventionVSAvoidheating structure complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent removes the cotton wrapping material from the heating structure entirely. Instead of heating wrapped cotton, the liquid flows directly through channels in the heating body, eliminating the source of liquid leakage and cotton scorching problems while simplifying the overall structure.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical cotton wrapping system with a direct liquid flow channel system. Liquid is guided through predetermined channels in the heating body rather than being absorbed by cotton, achieving more reliable heating without the drawbacks of cotton-based systems.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If heating wires are only printed at bottom of heat generating body, then structure is simple, but overall heating effect is poor and liquid is easy to be inhaled

Engineering Contradiction:

Improveheating sufficiencyVSAvoidheating wire distribution

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent transitions from bottom-only heating (2D surface heating) to three-dimensional heating by embedding heating wires throughout the bulk of the heating body. This volumetric heating distribution ensures complete heating of the liquid as it flows through channels, preventing inhalation of unheated liquid while maintaining structural integrity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent implements non-uniform heating wire distribution concentrated in regions where liquid flow is most critical. Heating wires are densely arranged in channel regions and sparsely arranged in non-channel regions, optimizing heating efficiency while controlling manufacturing complexity.

Inventive Principle:

Principle #3Local quality

3Manufacturing precision

If cotton is used for liquid conduction, then liquid can reach heating body, but atomization is uneven and smell/taste are affected

Engineering Contradiction:

Improveatomization uniformityVSAvoidheating body structure

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent replaces the cotton-based liquid conduction system with a direct channel-based system. Liquid flows through precisely formed channels in the heating body, ensuring uniform distribution and heating. This eliminates the uneven atomization and contamination issues associated with cotton while maintaining manufacturability through standardized channel formation processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
