Solution Overview

Problem

Existing electronic cigarettes have complex operations, difficulty in cleaning due to the atomizer and heating wire design, and clogging issues with tobacco paste, especially when using solid forms, which limits convenience and usability.

Innovation Solution

A convenient smoking device design with a battery unit and pipe inside the main body, where the electric heating wire is external and connected to the atomizer, allowing for external tobacco paste heating without the need for internal storage, easy cleaning, and operation at any angle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the atomizer and heating wire are provided within a main body, then the device structure is compact, but cleaning becomes difficult and clogging occurs

Engineering Contradiction:

Improvedevice structure compactnessVSAvoidcleaning ease

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The device is divided into separate functional modules: a removable atomizer assembly that can be detached from the main body, allowing the heating wire and atomizer to be separated for easy cleaning and maintenance while maintaining a compact overall structure when assembled

Inventive Principle:

Principle #1Segmentation

2Volume of moving object

If the atomizer and heating wire are provided within a main body, then the device structure is compact, but residual tobacco paste causes clogging in the pore

Engineering Contradiction:

Improvedevice structure compactnessVSAvoidclogging resistance

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The heating wire is extracted from the enclosed atomizer structure and extended externally, allowing tobacco paste to be heated outside the main body pore structure. This prevents residual paste from accumulating and clogging the internal pore channels while maintaining device compactness

Inventive Principle:

Principle #2Taking out (Extraction)

3Device complexity

If the tobacco paste is heated in the atomizer, then the tobacco paste is transformed into gaseous form, but the liquefied tobacco paste flows into the pore or out from the nozzle

Engineering Contradiction:

Improveheating process simplicityVSAvoidusage convenience

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

A ceramic seat is introduced as an intermediary component to contain and heat the tobacco paste externally. The ceramic material provides thermal insulation and containment, allowing heating to occur outside the main body pore structure, preventing paste from flowing into the pore while still enabling efficient vaporization

Inventive Principle:

Principle #24Intermediary (Mediator)

4Device complexity

If the tobacco paste in solid forms is heated, then the tobacco paste is liquefied, but it attaches to walls of the pore when cooling down, which is difficult to clean

Engineering Contradiction:

Improveheating process simplicityVSAvoidcleaning ease

Core Design Contradiction:

Device complexityVSEase of repair

Solution Approach 1:

The heating process is extracted from the enclosed pore structure and moved to an external ceramic seat. This allows the liquefied tobacco paste to be contained and cooled outside the pore walls, preventing attachment and accumulation on internal surfaces that would be difficult to clean

Inventive Principle:

Principle #2Taking out (Extraction)

5Reliability

If the electronic cigarette is used vertically to prevent tobacco paste flowing, then clogging is prevented, but operation becomes less convenient

Engineering Contradiction:

Improveclogging preventionVSAvoidusage flexibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The ceramic seat acts as a mediator that contains the tobacco paste during heating externally. This containment structure prevents paste from flowing into the pore regardless of device orientation, allowing the user to operate the device at any angle without risking clogging

Inventive Principle:

Principle #24Intermediary (Mediator)
