Solution Overview

Problem

Existing smoking alternatives like e-cigarettes contain harmful chemicals and do not provide a chemical-free inhaling experience.

Innovation Solution

A device with a cooled module and air-conveying circuit that maintains the inhaled air below 32°F, using a Peltier cell for cooling and a micro-fan for air circulation, optionally with a flavor cartridge, providing a refreshing and chemical-free inhalation sensation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If e-cigarettes heat liquid to produce vapor, then inhalation sensation is provided, but harmful chemicals are introduced into the inhaled air

Engineering Contradiction:

Improveinhalation sensationVSAvoidharmful chemicals

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The invention extracts and removes the harmful heating and chemical vaporization process from the inhalation system, retaining only the cooling and sensation-providing functions. The cooled module eliminates the need for heating liquid, thereby removing harmful chemicals while preserving the refreshing inhalation experience.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the temperature parameter of the inhaled air from hot (heated vapor) to cold (below 32°F), fundamentally altering the inhalation experience. This parameter change allows providing sensation without chemicals by using cooled air instead of heated vapor.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If a cooling module is added to cool the inhaled air, then refreshing sensation is enhanced, but device complexity increases

Engineering Contradiction:

Improverefreshing sensationVSAvoiddevice structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The cooled module serves multiple functions simultaneously: it cools the inhaled air to provide refreshing sensation, and its insulated housing also serves as part of the device structure. The Peltier cell integrates cooling functionality without requiring separate complex refrigeration systems, thereby enhancing sensation while limiting complexity increase.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Duration of action of stationary object

If the module is kept frozen for extended periods, then cooling effect is maintained, but bacterial growth risk increases

Engineering Contradiction:

Improvecooling durationVSAvoidbacterial growth

Core Design Contradiction:

Duration of action of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The housing is made from a composite material containing antimicrobial agents (silver, copper, or zinc particles) embedded in the polymer matrix. This composite structure provides both structural integrity and bacterial protection, allowing the module to remain frozen for extended periods while preventing microbial contamination.

Inventive Principle:

Principle #40Composite materials

4Temperature

If a Peltier cell is used for active cooling, then temperature control is improved, but energy consumption increases

Engineering Contradiction:

Improvemodule temperatureVSAvoidenergy consumption

Core Design Contradiction:

TemperatureVSUse of energy by moving object

Solution Approach 1:

The Peltier cell operates periodically rather than continuously, being activated only when temperature control is needed. This periodic operation allows precise temperature control when required while minimizing overall energy consumption during extended cooling periods where passive insulation suffices.

Inventive Principle:

Principle #19Periodic action
