Solution Overview

Problem

Existing atomizers have a low space utilization rate in their liquid storage cavities due to liquid storage cotton completely adsorbing the liquid substrate, limiting the amount of liquid that can be stored.

Innovation Solution

The liquid storage cavity is divided into two longitudinally distributed portions, with a first portion for storing liquid substrate and a second portion containing a liquid storage member, where a first liquid guide member transfers the liquid substrate to the storage member, which is then atomized by an atomization assembly, allowing the liquid substrate to remain in a liquid form in the first portion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If liquid storage cotton fills the entire liquid storage cavity to completely adsorb the liquid substrate, then the liquid substrate can be effectively stored and transferred, but the space utilization rate of the liquid storage cavity becomes low

Engineering Contradiction:
Improveamount of liquid substrate storedVSAvoidspace utilization rate of liquid storage cavity
Core Design Contradiction:
Quantity of substanceVSVolume of stationary object

Solution Approach 1:

The liquid storage cavity is divided into a first liquid storage cavity and a second liquid storage cavity. The first cavity stores liquid substrate in liquid form without complete adsorption, while the second cavity contains atomization cotton for localized absorption and atomization. This segmentation allows different regions to serve different functions, improving overall space utilization while maintaining adequate liquid storage capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the liquid storage cavity are given different qualities: the first cavity maintains a liquid-substrate-friendly environment without extensive adsorbent material, while the second cavity provides localized adsorption capability where needed for atomization. This local differentiation optimizes both storage efficiency and atomization performance.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If liquid storage cotton is used to absorb and transfer liquid substrate, then the liquid can be delivered to the heating element, but the cotton occupies excessive space in the liquid storage cavity

Engineering Contradiction:
Improveliquid substrate transfer capabilityVSAvoidspace occupied by liquid storage cotton
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The atomization cotton is extracted from the entire liquid storage cavity and relocated to only the second liquid storage cavity. This extraction removes the excessive space occupation from the first cavity while preserving the necessary liquid transfer capability in the second cavity where the cotton remains to facilitate substrate delivery to the heating element.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The second liquid storage cavity acts as an intermediary zone between the first cavity (liquid storage) and the heating element (atomization). The atomization cotton in this intermediate region facilitates liquid transfer without occupying space in the primary storage area, enabling efficient liquid delivery while maximizing storage capacity.

Inventive Principle:
Principle #24Intermediary (Mediator)
