Solution Overview

Problem

Existing nicotine compositions for aerosol generation devices often result in a bitter taste and undesirable throat sensations, and may damage device components or produce undesirable compounds, limiting user satisfaction and device compatibility.

Innovation Solution

A nicotine composition comprising a molar excess of nicotine relative to organic acids, specifically using benzoic acid and/or citric acid along with at least one further organic acid, which forms a nicotine salt and maintains a nicotine concentration of less than 1.5 wt% in the composition, enhancing taste satisfaction and throat sensation while minimizing device damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional nicotine compositions are used in aerosol generation devices, then nicotine delivery is achieved, but bitter taste and undesirable throat sensations occur

Engineering Contradiction:
Improvebitter taste and throat irritationVSAvoiduser satisfaction
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent applies parameter changes by carefully controlling the molar ratio of nicotine to organic acids (maintaining nicotine in molar excess) and limiting nicotine concentration to less than 1.5 wt%. This specific parameter optimization resolves the contradiction by reducing bitter taste and throat irritation while maintaining reliable nicotine delivery and user satisfaction.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses composite materials by formulating a nicotine composition that includes nicotine, organic acids (such as benzoic acid, citric acid, or lactic acid), and carrier substances (propylene glycol and/or vegetable glycerol). This composite formulation creates a balanced system that mitigates harmful sensory effects while preserving nicotine delivery functionality.

Inventive Principle:
Principle #40Composite materials

2Reliability

If nicotine compositions with higher nicotine content are used, then nicotine impact is enhanced, but device components are damaged and undesirable compounds are generated

Engineering Contradiction:
Improvenicotine impactVSAvoiddevice damage and undesirable compounds
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent optimizes the nicotine concentration parameter to be less than 1.5 wt%, which is a critical threshold that balances nicotine impact with device safety. This parameter control prevents excessive nicotine from damaging device components or generating undesirable compounds, while still delivering sufficient nicotine impact through the molar excess ratio relative to organic acids.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces organic acids as intermediary substances that mediate between nicotine and device components. These organic acids (benzoic acid, citric acid, lactic acid) form salts with nicotine, creating a buffer system that reduces free acid reactions with device components, thereby protecting the device while maintaining nicotine delivery.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If free organic acids are present in the composition, then throat sensation is enhanced, but device components are corroded and undesirable reactions occur

Engineering Contradiction:
Improvethroat sensationVSAvoiddevice corrosion and unwanted reactions
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent uses organic acids as intermediaries that form nicotine salts, creating a buffered system. This intermediary approach allows the composition to provide throat sensation through controlled acid presence while the nicotine salt formation prevents excessive free acid from corroding device components or generating undesirable reactions.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent controls the pH and buffering capacity parameters by maintaining nicotine in molar excess relative to organic acids. This parameter control ensures that enough organic acid is present to provide throat sensation, but not so much that it causes device corrosion, achieving a balanced state through precise compositional optimization.

Inventive Principle:
Principle #35Parameter changes
