Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tobacco foams used in e-cigarettes often result in an uneven smoking profile due to inefficient extraction of key compounds, leading to inconsistent flavor and vaporization experiences.
Innovation Solution
A foam composition comprising a tobacco ingredient agent, an aerosol forming agent, a foam stabilizing agent, and a foam forming agent, with specific weight percentages to ensure homogeneous evaporation and aerosol generation without combustion, using a method that involves mixing and heating these components to create a stable foam structure for efficient vaporization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional tobacco foams are used in e-cigarettes, then aerosol can be generated, but the smoking profile becomes uneven due to inefficient extraction of key compounds
Solution Approach 1:
The patent modifies the physical and chemical parameters of the foam structure, including cell size distribution, wall thickness, and material composition, to optimize heat transfer and mass extraction efficiency during vaporization, thereby achieving consistent smoking profile and improved extraction of key compounds
Solution Approach 2:
The patent employs composite foam structures combining different materials with complementary properties - such as cellulose acetate for biocompatibility, polyethylene for structural stability, and incorporated flavor compounds - to enhance both extraction efficiency and smoking consistency
2Reliability
If foam forming agents are used to create stable foam structure, then aerosol generation is enabled, but the complexity of the composition increases
Solution Approach 1:
The patent selects foam forming agents that perform multiple functions simultaneously - such as propylene glycol and glycerol that serve as both foam stabilizers and aerosol carriers, and cellulose acetate that provides both structural integrity and biocompatibility - thereby reducing the number of separate components needed and simplifying the overall composition

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 provides a consistent and efficient release of tobacco flavors and aerosol, improving the smoking experience by ensuring uniform vaporization and flavor delivery across multiple puffs, as demonstrated by the stable smoking profile and reduced harshness of the aerosol produced.
Implementation Method 1
a foam forming agent, and a foam stabilizing agent, wherein the weight of the tobacco ingredient containing agent and/or the inhalable agent is 0.1-33 wt.-% of the weight of the foam, and the weight of the aerosol forming agent is 10-70 wt.-% of the weight of the foam
Implementation Method 2
The inventors have found that an aerosol containing a tobacco ingredient containing agent and/or an inhalable agent can be more homogeneously released from a foam wherein an aerosol forming agent is contained
Implementation Method 3
provides a consistent and efficient release of tobacco flavors and aerosol, improving the smoking experience by ensuring uniform vaporization and flavor delivery

AI summary
A foam includes a tobacco ingredient containing agent and/or an inhalable agent, an aerosol forming agent, a foam stabilizing agent, and a foam forming agent. In one embodiment, a weight of the tobacco ingredient containing agent and/or the inhalable agent is 0.1-33 wt.-% of a weight of the foam, and a weight of the aerosol forming agent is 10-80 wt. % of the weight of the foam. In another embodiment, the foam forming agent is a non-protein contain polysaccharide and a weight of the foam forming agent is less than 20 wt.-% of the foam.
