Solution Overview

Problem

Existing tobacco heating devices face challenges with the production and handling of reconstituted tobacco sticks, which are prone to crumbling and disintegration, making them difficult to use and requiring complex production processes, and they often limit the variety of aromas available to users.

Innovation Solution

A bulk solid reconstituted plant composition comprising plant extract, refined plant fibers, and an aerosol-generating agent, with a cohesive structure that allows heated air to pass through, preventing crumbling and enabling easy handling and varying aromas by adjusting the composition's ingredients.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If reconstituted tobacco sticks are used in heating devices, then aerosol generation capability is improved, but handling ease deteriorates due to crumbling and disintegration

Engineering Contradiction:
Improveaerosol generation capabilityVSAvoidhandling ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies composite materials by combining reconstituted tobacco with binders and additives to create a unified mass with improved mechanical properties. This composite structure prevents crumbling and disintegration while maintaining aerosol generation capability, directly resolving the contradiction between reliability and ease of operation.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent changes physical parameters such as density, moisture content, and particle size distribution of the reconstituted tobacco mass. By optimizing these parameters, the material achieves both structural integrity for easy handling and sufficient porosity for effective aerosol generation during heating.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If traditional tobacco stick production methods are used, then aerosol-generating agent absorption is improved, but manufacturing complexity increases due to numerous production steps

Engineering Contradiction:
Improveaerosol-generating agent absorptionVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple production steps into a single integrated process. Instead of separately preparing tobacco leaves, cutting them, and assembling sticks, the invention uses a continuous extrusion or molding process that produces ready-to-use tobacco masses, significantly simplifying manufacturing while maintaining absorption properties.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent extracts the essential functional properties (aerosol-generating agent absorption and release) from the traditional stick structure and implements them in a simplified mass format. This extraction allows the material to maintain effectiveness while eliminating unnecessary structural complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If tobacco sticks are designed for easy handling, then user convenience is improved, but structural integrity may deteriorate

Engineering Contradiction:
Improveuser convenienceVSAvoidstructural integrity
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The patent optimizes physical parameters including moisture content (10-20%), density (0.6-1.2 g/cm³), and particle size distribution to achieve an optimal balance. These parameter adjustments ensure the material is soft enough for easy handling but structurally sound enough to maintain integrity during insertion and heating.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The use of composite materials with binders and additives creates a unified structure that is both mechanically robust and easy to handle. The composite nature allows simultaneous optimization of handling properties and structural strength without compromise.

Inventive Principle:
Principle #40Composite materials
