Solution Overview

Problem

Existing aerosol provision systems, such as electronic cigarettes and heat-not-burn products, lack effective and efficient compositions that can deliver specific active agents without the need for combusting tobacco, while providing sensory and physiological effects.

Innovation Solution

Aerosolizable compositions comprising an aerosol former and an active agent, such as substituted 3-(1-methylpyrrolidin-2-yl)pyridine, 3-(azetidin-2-yl)pyridine, or 3-(azetidin-2-ylmethoxy)pyridine, are used to generate aerosols in aerosol delivery devices, which are designed to deliver active substances without combustion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If tobacco combustion is used to deliver active substances, then physiological and sensorial effects are achieved, but harmful factors and safety issues arise

Engineering Contradiction:

Improveharmful factors from tobacco combustionVSAvoideffectiveness of active substance delivery

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent extracts and eliminates tobacco combustion from the system, retaining only the essential function of delivering active substances. The composition delivers nicotine and other compounds through aerosolization without requiring tobacco material or combustion processes, thereby removing harmful combustion byproducts while maintaining therapeutic effects.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the physical state and delivery parameters of active substances from combustion-based vapor to aerosolized liquid suspension. By formulating a specific composition with aerosol-forming agents and controlling particle size distribution, the system achieves effective substance delivery through inhalation without the high temperatures and chemical reactions associated with combustion.

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If aerosolizable compositions with active agents are used, then tobacco combustion is eliminated, but composition formulation complexity increases

Engineering Contradiction:

Improvetobacco combustion eliminationVSAvoidcomposition formulation complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent employs a multi-functional composition formulation where a single aerosolizable composition simultaneously delivers multiple active substances (nicotine, terpenes, flavonoids), provides sensory effects, ensures stable aerosol generation, and maintains safety. This consolidates what could be multiple separate formulation challenges into one integrated system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention uses a composite aerosolizable composition combining multiple components including nicotine or its salts, aerosol-forming agents, terpenes, flavonoids, and other excipients. This composite formulation leverages the synergistic properties of each component to achieve effective active substance delivery, sensory effects, and aerosol stability while simplifying the overall system design.

Inventive Principle:

Principle #40Composite materials

3Reliability

If substituted 3-(1-methylpyrrolidin-2-yl)pyridine compounds are used as active agents, then physiological effects are enhanced, but manufacturing precision requirements increase

Engineering Contradiction:

Improvephysiological effect effectivenessVSAvoidactive agent structure precision

Core Design Contradiction:

ReliabilityVSManufacturing precision

Solution Approach 1:

The patent applies local quality modifications by introducing specific substituents at defined positions on the pyrrolidinylpyridine core structure. The substituents (R1-R6 groups) are strategically placed to optimize receptor binding affinity and physiological effects while maintaining synthetic feasibility. This localized structural optimization allows precise control over activity without requiring complete structural redesign.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The invention systematically varies molecular parameters such as substituent types (alkyl, alkoxy, halogen, cyano groups), their positions on the ring structure, and stereochemistry to optimize physiological effects. By changing these molecular parameters in a structured manner, the patent achieves enhanced effectiveness while maintaining practical manufacturing capabilities through established organic synthesis methods.
