Solution Overview

Problem

Existing nicotine pouches face challenges in achieving appropriate nicotine release and absorption rates, leading to either insufficient user satisfaction or nicotine irritation and short duration of use.

Innovation Solution

A nicotine pouch design incorporating a filler with nicotine, a release control excipient such as cellulose and sugar alcohol, a binder, a pH adjuster, and a flavoring agent, packaged in a material comprising pulp, cellulosic staple fibers, and thermoplastic fibers, optimized for controlled nicotine elution and absorption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the amount of nicotine eluted through the packaging material is increased, then user satisfaction is improved, but nicotine irritation and shortening of duration occur

Engineering Contradiction:

Improvenicotine elution amountVSAvoidnicotine irritation

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by precisely controlling the nicotine content in the filler (2.5 to 10 wt%) and the ratio of release control excipient to nicotine (5.5 to 36 times), thereby optimizing the elution rate to achieve appropriate nicotine release without excessive irritation

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The packaging material acts as an intermediary substance that mediates between the nicotine filler and the user's mouth, controlling the release rate of nicotine through its specific composition (pulp, cellulosic staple fiber, thermoplastic fiber) to prevent rapid absorption while maintaining sufficient delivery

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If the amount of nicotine eluted through the packaging material is increased, then user satisfaction is improved, but the duration of nicotine pouch use is shortened

Engineering Contradiction:

Improvenicotine elution amountVSAvoidduration of nicotine pouch use

Core Design Contradiction:

Quantity of substanceVSDuration of action of moving object

Solution Approach 1:

The patent controls the nicotine content parameter (2.5 to 10 wt%) and excipient ratio (5.5 to 36 times) to achieve a balanced elution rate that maintains sufficient nicotine delivery while extending the duration of use by preventing rapid absorption

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The packaging material enables continuous and controlled nicotine release over an extended period by acting as a barrier that gradually allows nicotine to diffuse into the mouth, ensuring sustained action rather than rapid depletion

Inventive Principle:

Principle #20Continuity of useful action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution effectively adjusts nicotine release and absorption rates, providing user satisfaction by ensuring a consistent and appropriate nicotine delivery, while minimizing irritation and prolonging the duration of use.

Implementation Method 1

allows saliva to pass through the nicotine pouch filler, and a flavor and nicotine released from the nicotine pouch filler diffuse into the user's mouth

Methodology Applied

Scientific EffectDiffusion: Diffusion

Implementation Method 2

When the amount of nicotine eluted through the packaging material is too small, it is difficult to provide the user with smoking satisfaction

Methodology Applied

Scientific EffectElution: Absorption (physical)
