Solution Overview

Problem

Existing electronic atomization devices suffer from non-proportional atomization, leading to poor consistency in taste before and after inhalation due to varying atomization temperatures and substance availability in different regions.

Innovation Solution

An atomizing core with a blocking member in the second atomization region to prevent aerosol-forming medium atomization at low temperatures, focusing atomization solely in the first region with the heating member, ensuring proportional atomization and maximizing oversaturation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the atomization surface includes both first and second atomization regions, then the heating member can be positioned in a region with sufficient space, but non-proportional atomization occurs and taste consistency deteriorates

Engineering Contradiction:

Improveheating member positioningVSAvoidtaste consistency

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The atomization surface is segmented into a first atomization region (where the heating member is located) and a second atomization region (surrounding the first region). This segmentation allows the heating member to be positioned in the center with adequate space while directing atomization primarily in the first region to maintain taste consistency.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the atomization surface are assigned different functions: the first atomization region is optimized for proportional atomization and taste consistency, while the second atomization region serves as a surrounding zone. This local differentiation resolves the conflict between heating member positioning and taste consistency.

Inventive Principle:

Principle #3Local quality

2Productivity

If the second atomization region allows atomization, then more aerosol-forming medium can be processed, but low-boiling-point substances atomize first causing non-proportional atomization

Engineering Contradiction:

Improveaerosol-forming medium processing capacityVSAvoidatomization proportionality

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The atomization surface is divided into two distinct regions with different atomization characteristics. The first region ensures proportional atomization of all substances, while the second region's atomization is controlled to occur after the first region, maintaining overall atomization proportionality while increasing processing capacity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first atomization region performs preliminary atomization of the aerosol-forming medium at higher temperatures, ensuring that all substances including low-boiling-point substances are atomized proportionally before the second region becomes active, thus preventing premature atomization of volatile components.

Inventive Principle:

Principle #10Preliminary action

3Area of stationary object

If atomization occurs in both first and second regions, then the atomization surface area is fully utilized, but energy is wasted in the second region with lower atomization temperature

Engineering Contradiction:

Improveatomization surface area utilizationVSAvoidenergy waste in second region

Core Design Contradiction:

Area of stationary objectVSLoss of energy

Solution Approach 1:

The atomization surface is segmented into two functional regions: the first region serves as the primary atomization zone with efficient energy utilization, while the second region acts as a secondary zone that supplements atomization capacity without significant energy waste, as it operates at lower temperatures and processes remaining aerosol-forming medium.

Inventive Principle:

Principle #1Segmentation

4Stability of the object's composition

If the heating member is positioned centrally, then structural stability is improved, but the atomization surface periphery remains underutilized

Engineering Contradiction:

Improvestructural stabilityVSAvoidatomization surface utilization

Core Design Contradiction:

Stability of the object's compositionVSArea of stationary object

Solution Approach 1:

The atomization surface is segmented into a central first atomization region (where the heating member is positioned for structural stability) and a peripheral second atomization region. This segmentation allows the heating member to remain centrally positioned while the peripheral second region is utilized for supplementary atomization, thus maintaining both structural stability and surface area utilization.

Inventive Principle:

Principle #1Segmentation
