Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production process of heat-not-burn aerosol-generating articles is complex, requiring significant manpower and resources, and existing articles face issues with high suction resistance and low smoke volume due to their filament or granular shapes, making filling and operation inconvenient and difficult to control.
Innovation Solution
A paste-like HNB aerosol-generating article is developed, composed of aerosol-generating raw materials, agents, and water, which is mixed into a paste form with controlled porosity and injected into a cartridge tube, forming a loose columnar body with internal pores to reduce suction resistance and enhance smoke release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If filament or granular shapes are used for aerosol-generating articles, then the production process becomes complex and manual filling is required, but the suction resistance becomes too large and smoke volume becomes too small
Solution Approach 1:
The patent changes the physical state parameter from solid filament/granular forms to a paste-like semi-liquid form, which enables better control over density and porosity during manufacturing, resulting in optimized suction resistance and smoke volume
Solution Approach 2:
The patent uses a composite paste material containing aerosol-generating raw materials, aerosol-generating agents, and water in specific proportions, creating a material that simultaneously achieves ease of manufacture and optimal suction characteristics
2Ease of manufacture
If filament or flake shapes are used, then the articles can be produced, but manual filling is required which is inconvenient and difficult to control
Solution Approach 1:
The patent employs pneumatic injection technology to automatically inject the paste-like aerosol-generating article into the cartridge tube, replacing manual filling operations with an automated pneumatic system that provides precise control over filling amount
Solution Approach 2:
By changing the material state to a pumpable paste form with controlled viscosity and density, the patent enables automated pneumatic injection while maintaining precise control over the filling amount
3Extent of automation
If automated machinery is used for filling, then filling operation becomes mechanized, but the machinery becomes very complicated and filling amount consistency is difficult to achieve
Solution Approach 1:
The patent uses a relatively simple pneumatic injection system rather than complex automated machinery, achieving automation through pneumatic pressure differential that is easier to control and less mechanically complex
Solution Approach 2:
By optimizing the paste material parameters (viscosity, density, flow characteristics), the patent enables consistent filling amounts to be achieved with simpler pneumatic equipment rather than requiring complex automated machinery
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 paste-like article provides uniform heat conduction, reduces suction resistance to 0.75-1.5 Kpa, and allows smooth aerosol release, mimicking traditional cigarette suction, while producing smokeable aerosol without harmful tar, and offering a better smoking experience.
Implementation Method 1
The aerosol-generating raw material, the aerosol-generating agent, and the water are mixed and blended into paste, so that the HNB aerosol-generating article is in a shape of paste stick. Wherein the paste stick HNB aerosol-generating article is injected into the HNB cartridge tube and has internal pores to allow aerosol to penetrate and exude, a porosity thereof is 40-75% when heating and drying
Implementation Method 2
heat-not-burn aerosol-generating article... produces smokeable aerosol without harmful tar... when heated to 200-300°C

AI summary
The present disclosure relates to a heat-not-burn (HNB) aerosol-generating article, which comprises aerosol-generating raw material, aerosol-generating agent, and water. The aerosol-generating raw material is pre-pulverized and then sieved through a 40-200 mesh sieve. The aerosol-generating raw material, the aerosol-generating agent, and water are mixed in a certain proportion and blended into paste, so that the HNB aerosol-generating article is in a shape of paste stick when extruded, and is used to be injected into the HNB cartridge tube by extrusion into the paste stick. The paste stick HNB aerosol-generating article has internal pores in a form of loose paste stick. When the user performs a suction action, the pores are convenient for the aerosol passing through the paste stick HNB aerosol-generating article into the human mouth smoothly. The above-mentioned HNB aerosol-generating article is suitable for HNB non-tobacco products or HNB tobacco products and the like.
