High-Density Reconstituted Plant Sheet for Tobacco Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tobacco is not suitable for heating devices that heat tobacco without burning it, as it fails to generate a sufficient amount of aerosol with desirable organoleptic properties and nicotine transfer rate, making the user experience inferior to that of a conventional cigarette.
Innovation Solution
A reconstituted plant sheet with a density of at least 0.6 g/cm3, comprising refined plant fibers, an aerosol-generating agent, and a plant extract, where the total content of the aerosol-generating agent is between 10% and 29% by weight, improving nicotine transfer and organoleptic properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional tobacco is used in heating devices, then the device structure is simple, but the aerosol generation amount and organoleptic properties are insufficient
Solution Approach 1:
The patent changes the physical and chemical parameters of tobacco by reconstituting it with specific densities (0.5-1.5 g/cm³) and controlling the content of aerosol-generating agents (5-40% by weight), thereby improving aerosol generation while maintaining compatibility with heating devices
Solution Approach 2:
The patent creates composite reconstituted tobacco materials combining tobacco extracts, aerosol-generating agents, and binding agents to achieve both sufficient aerosol generation and good organoleptic properties suitable for heating devices
2Productivity
If reconstituted tobacco with low aerosol-generating agent content (3%) is used, then the device complexity is low, but the nicotine transfer rate and aerosol amount are too low to be satisfactory
Solution Approach 1:
The patent optimizes the concentration parameter of aerosol-generating agents to 10-29% by weight in reconstituted tobacco, which significantly improves nicotine transfer rate and aerosol generation while maintaining manufacturing feasibility
3Productivity
If the density of reconstituted plant sheet is increased to at least 0.6 g/cm³, then the nicotine transfer rate is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent controls the density parameter of reconstituted plant sheet within 0.5-1.5 g/cm³ (preferably 0.6-1.2 g/cm³) to optimize nicotine transfer rate while maintaining manufacturability through standard papermaking processes
Solution Approach 2:
The patent allows flexibility in density parameters within specified ranges, enabling manufacturers to adjust processing conditions (fiber refinement, pressing, drying) to achieve optimal density without requiring complex manufacturing systems
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 reconstituted plant sheet enhances the nicotine transfer rate and organoleptic properties of the aerosol, providing a user experience closer to that of a conventional cigarette, with improved aerosol generation and reduced exposure to harmful constituents.
Implementation Method 1
the tobacco is heated at a temperature below the combustion temperature without being burnt, which leads to the formation of an aerosol
