Solution Overview

Problem

Existing electronic cigarette atomizers lack the ability to control the volume of tobacco liquid conveyed to the heating element for atomization, resulting in inconsistent aerosol production.

Innovation Solution

An atomizer design incorporating a liquid drive component with a forced pump and button, or an electric pump, connected to a U-shaped liquid conducting pipe, allowing controlled conveyance of tobacco liquid to the heating element, which includes a protective layer for efficient atomization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a liquid drive component with pump is added to control tobacco liquid volume, then the measurement precision and control capability of tobacco liquid volume is improved, but the device complexity increases

Engineering Contradiction:
Improvetobacco liquid volume controlVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical pump systems with a heating element that utilizes thermal expansion and vaporization principles. The heating element heats the tobacco liquid to generate vapor pressure, which naturally drives the liquid flow without requiring mechanical pumps or complex volume control mechanisms. This substitution of mechanical systems with thermal-physical principles simplifies the device structure while maintaining precise control capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent controls tobacco liquid volume by changing the heating parameters (temperature, heating time, power) rather than using mechanical volume control mechanisms. By adjusting the heating element's parameters, the system can precisely control the amount of liquid vaporized and conveyed, achieving accurate measurement and control without adding complex mechanical components.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If heating element with protective layer is used for atomization, then the reliability and atomization efficiency is improved, but the device complexity increases

Engineering Contradiction:
Improveheating element protectionVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a thin protective layer (such as a coating or film) on the heating element surface to protect it from direct contact with tobacco liquid while allowing heat transmission. This thin film approach provides reliable protection without significantly increasing device complexity, as the layer is integrated into the heating element structure rather than being a separate component.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The heating element is constructed using composite materials that combine protective properties with heating functionality. The protective layer and heating element form a composite structure where the outer layer provides protection and chemical resistance, while the inner layer provides heating capability. This integration of multiple functions into a single composite component improves reliability without proportionally increasing complexity.

Inventive Principle:
Principle #40Composite materials
