Solution Overview

Problem

Existing e-cigarettes struggle to provide an aerosol that mimics the flavor and nicotine delivery of traditional tobacco products, leading to an inconsistent vaping experience, and there is a desire to reduce harmful toxicants.

Innovation Solution

An aerosolisable formulation comprising water, flavors, and encapsulating materials like substituted cyclodextrins with a binding energy of -0.5 to -8 kcal/mol, which encapsulates flavors and nicotine, providing a stable flavor delivery and reducing the need for glycerol and propylene glycol.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional e-cigarette formulations using glycerol and propylene glycol are used, then vapor generation is achieved, but flavor consistency and nicotine delivery are insufficient

Engineering Contradiction:
Improveflavor delivery consistencyVSAvoidvaping experience consistency
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent changes the physical-chemical parameters of the formulation by introducing cyclodextrin encapsulation complexes with specific binding energies (-0.5 to -8 kcal/mol), transforming how flavors and nicotine are delivered from the liquid phase through controlled aerosolization, thereby achieving more consistent and controllable flavor delivery

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite formulation system combining water, nicotine, flavors, and cyclodextrin encapsulating materials, where the cyclodextrin-flavor-nicotine complexes form a new composite structure that enables controlled release and consistent delivery during vaping

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If e-cigarettes are designed to mimic tobacco smoke, then consumer acceptance improves, but toxicant formation increases

Engineering Contradiction:
Improvetobacco-like experienceVSAvoidtoxicant formation
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The patent extracts and isolates the essential components for tobacco-like experience (flavors and nicotine) by encapsulating them in cyclodextrin complexes, separating these desired elements from the harmful byproducts that form during traditional heating and vaporization of glycerol/propylene glycol bases

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the thermal and chemical parameters of the vaporization process by using cyclodextrin-encapsulated formulations, which alter how flavors and nicotine are released during heating, aiming to reduce the formation of toxicants while maintaining tobacco-like sensory experience

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If encapsulating materials with high binding energy are used, then flavor stability improves, but flavor release is reduced

Engineering Contradiction:
Improveflavor stabilityVSAvoidflavor release
Core Design Contradiction:
Stability of the object's compositionVSQuantity of substance

Solution Approach 1:

The patent optimizes the binding energy parameter of the encapsulating material to fall within the specific range of -0.5 to -8 kcal/mol, creating a balanced state where flavors are stable during storage but release appropriately during vaping, resolving the trade-off between stability and release

Inventive Principle:
Principle #35Parameter changes
