Solution Overview

Problem

Existing methods for flavoring and aging smoking materials fail to enhance the taste and flavor of tobacco, limited by the types of tobacco leaves and additives, and do not effectively deliver fragrance components to meet smokers' preferences.

Innovation Solution

A method involving flavoring smoking materials with a sum of flavoring and base solution ranging from 1% to 20% of the total weight, adjusting moisture to 15-35 wt%, aging at 60-80°C and 20-40% humidity for 7-25 days, and including preconditioning, moisturizing, cutting, and drying processes to enhance flavor persistence and reduce irritation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If existing flavoring and aging methods are used, then the basic tobacco taste can be maintained, but the flavor persistence and fragrance delivery are insufficient

Engineering Contradiction:
Improveflavor persistenceVSAvoidfragrance delivery effectiveness
Core Design Contradiction:
Quantity of substanceVSReliability

Solution Approach 1:

The patent applies preliminary action by flavoring the tobacco material before the aging process rather than after. This sequence allows the fragrance components to be integrated into the tobacco matrix during aging, enabling gradual release and improved flavor persistence while maintaining effective fragrance delivery throughout the product lifecycle

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent utilizes parameter changes by controlling specific aging conditions (temperature, humidity, time) to optimize the release characteristics of fragrance components. By adjusting these parameters, the system achieves both prolonged flavor persistence and reliable fragrance delivery without compromising the basic tobacco taste

Inventive Principle:
Principle #35Parameter changes

2Quantity of substance

If more flavoring materials are added to enhance taste, then the flavor intensity increases, but the irritation and off-taste increase

Engineering Contradiction:
Improveflavor intensityVSAvoidirritation
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent uses an intermediary approach by selecting and optimizing specific fragrance components that act as mediators between the tobacco base and the user's sensory experience. These carefully chosen flavoring materials enhance taste intensity while being formulated to minimize irritation and off-taste, resolving the contradiction between flavor strength and harmful effects

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies parameter changes by precisely controlling the concentration and composition of flavoring materials within optimal ranges. This ensures sufficient flavor intensity is achieved without exceeding thresholds that would cause irritation or off-taste, effectively balancing flavor enhancement with user comfort

Inventive Principle:
Principle #35Parameter changes
