Solution Overview

Problem

Existing oral products lack the ability to effectively tailor the release and sensory properties of flavorants and active ingredients, such as nicotine, through the use of humectants, leading to inconsistent delivery and user experience.

Innovation Solution

Incorporating a humectant into the composition of pouched oral products, either within the pouch or as a treatment on the pouch surface, to control the release of flavorants and active ingredients, with specific weight ratios and concentrations of humectant to water, enhancing sensory and functional profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a humectant is incorporated into the composition or pouch surface, then the release characteristics of flavorants and active ingredients can be tailored and sensory profile enhanced, but the product formulation complexity increases

Engineering Contradiction:
Improvedelivery consistencyVSAvoidformulation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies parameter changes by systematically varying the type, concentration, and placement of humectants (e.g., glycerol at different weight ratios from 0.05 to 5.0 relative to water) to optimize release characteristics. This allows precise control over flavorant and active ingredient delivery while managing formulation complexity through defined parameter ranges.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The humectant serves as an intermediary substance that mediates between the composition and the user's oral environment. It controls the interaction by regulating moisture retention and release rates, thereby tailoring the delivery of flavorants and active ingredients without requiring direct modification of the core composition.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-generated harmful factors

If glycerol content is reduced to less than 25% by weight, then harmful factors are reduced, but the humectant effectiveness may be compromised

Engineering Contradiction:
Improveharmful factorsVSAvoidhumectant effectiveness
Core Design Contradiction:
Object-generated harmful factorsVSReliability

Solution Approach 1:

The patent changes the parameter of glycerol concentration to less than 25% by weight while maintaining humectant effectiveness through compensating adjustments in other humectant types or ratios. This optimization reduces potential harmful factors associated with high glycerol content while preserving the desired moisture-retention and release characteristics.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite humectant systems where multiple humectants (including but not limited to glycerol) are combined in specific ratios. This composite approach allows the formulation to achieve effective humectancy with reduced individual component concentrations, particularly reducing glycerol content below 25% while maintaining overall effectiveness.

Inventive Principle:
Principle #40Composite materials
