Solution Overview

Problem

Conventional flavor suction articles either fail to provide sufficient flavor release due to low volatilization of components at normal temperatures or generate smoke and combustion products when heated, posing health risks.

Innovation Solution

A non-combustion type flavor suction article featuring a flavor-impermeable mouthpiece, a heat-melted capsule shell enclosing liquid flavor, and leak-protection members made of paper or acetate filters, wrapped with a tobacco sheet and heat-conducting materials, allowing controlled flavor release without smoke or combustion products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a conventional cigarette is smoked with ignition at high temperature, then flavor release is enhanced, but smoke and combustion products are generated causing health problems

Engineering Contradiction:
Improveflavor releaseVSAvoidsmoke and combustion products
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

The invention changes the temperature parameter from high-temperature combustion (>800°C) to low-temperature heating (80-140°C). This parameter change allows flavor release while avoiding combustion and smoke generation, directly resolving the contradiction between flavor enhancement and harmful byproduct formation

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention converts the harmful combustion process into a beneficial heating process. By using electric heating instead of combustion, the system achieves flavor release without producing harmful smoke and combustion products, effectively transforming a harmful mechanism into a beneficial one

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

2Temperature

If flavor-containing beads are used in electric heating cigarettes, then heating temperature is reduced, but smoke is still generated

Engineering Contradiction:
Improveheating temperatureVSAvoidsmoke
Core Design Contradiction:
TemperatureVSObject-generated harmful factors

Solution Approach 1:

The invention extracts the harmful smoke-generating component from the system by using a liquid flavor composition enclosed in a capsule instead of traditional tobacco or flavor beads that produce smoke. This extraction eliminates smoke generation while maintaining reduced heating temperature

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the physical state parameter from solid flavor beads to liquid flavor composition, and changes the heating temperature parameter to a specific range (80-140°C) that enables flavor release without smoke generation, resolving the contradiction between temperature reduction and smoke elimination

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If normal temperature suction is used with fiber bundle impregnated with flavor, then no combustion occurs, but volatilized components are insufficient for user satisfaction

Engineering Contradiction:
Improvecombustion avoidanceVSAvoidvolatilized components
Core Design Contradiction:
Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The invention introduces periodic heating action through an electric heater that heats the capsule during use. This periodic thermal energy input causes controlled volatilization of the liquid flavor, providing sufficient vapor for user satisfaction while maintaining combustion-free operation

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The invention changes the temperature parameter from normal temperature to elevated temperature (80-140°C) during use, enabling sufficient volatilization of flavor components while still avoiding combustion. This parameter change resolves the contradiction between combustion avoidance and adequate flavor vapor generation

Inventive Principle:
Principle #35Parameter changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables stable flavor retention and controlled release without smoke or combustion products, providing a healthier alternative for flavor enjoyment by heating the capsule to 80-140°C, ensuring the flavor is retained in leak-protection members and absorbed by the user.
