VSEngineering Contradiction Analysis

1Object-affected harmful factors

If tobacco-based materials are used in aerosol-generating systems, then aerosol production is achieved, but high levels of carbonyls are generated and ramp-up time is lengthy

Engineering Contradiction:
Improvecarbonyl exposureVSAvoidramp-up time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent changes the chemical composition parameters of the aerosol-generating material by incorporating specific additives (such as carbonyl scavengers like cysteine, glutathione, or amino acids) and optimizing the formulation of non-tobacco botanical materials. This compositional parameter change reduces carbonyl generation while the extrusion process optimizes physical parameters like porosity and surface area to accelerate aerosol production and reduce ramp-up time.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite aerosol-generating material that combines non-tobacco botanical materials with specific additives including carbonyl scavengers, flavorants, and other functional components. This composite formulation works synergistically to reduce harmful carbonyl exposure while maintaining efficient aerosol generation and reducing ramp-up time through optimized material architecture.

If tobacco-based materials are used in aerosol-generating systems, then aerosol production is achieved, but high levels of carbonyls are generated

Engineering Contradiction:
Improveaerosol production efficiencyVSAvoidcarbonyl generation
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful carbonyl generation process into a beneficial outcome by incorporating carbonyl scavenger additives that specifically target and neutralize carbonyl compounds. These additives are integrated into the aerosol-generating material formulation, allowing the system to maintain productive aerosol generation while the scavengers convert harmful carbonyls into less harmful substances, thereby reducing exposure without sacrificing productivity.

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

Solution Approach 2:

The patent modifies the chemical composition parameters by adding specific functional components (carbonyl scavengers such as cysteine, glutathione, homocysteine, or their derivatives) to the aerosol-generating material. This parameter change in the material composition enables the system to maintain high aerosol production efficiency while significantly reducing carbonyl generation through the chemical action of the scavengers.

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If non-tobacco botanical materials are used, then carbonyl exposure is reduced, but material composition optimization is required

Engineering Contradiction:
Improvecarbonyl exposureVSAvoidformulation complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent applies local quality by specifically targeting the carbonyl reduction function through dedicated additives (carbonyl scavengers) within the overall formulation. Rather than requiring complete reformulation of all material components, the solution locally addresses the carbonyl exposure issue by incorporating specific functional additives in optimized amounts, working synergistically with non-tobacco botanical materials to reduce carbonyls without excessive formulation complexity.

Inventive Principle:
Principle #3Local quality
