Core-shell tobacco particles prevent tar leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low-temperature non-burning cigarettes suffer from insufficient smoke, uneven smoking experience, and issues with tobacco tar leakage.
Innovation Solution
A low-temperature smoking body is developed, comprising tobacco particles with a particle body and a shell, where a carrier (raw tobacco material, non-tobacco material, or porous material) is distributed within or on the particle body, carrying a smoking agent (tobacco extract and/or atomizer) to enhance smoke production and stability, while the shell prevents leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric heating is used to volatilize smoke in tobacco filling materials, then smoking experience is similar to traditional tobacco, but smoke production is insufficient and smoking uniformity is poor
Solution Approach 1:
The tobacco filling material is segmented into tobacco particles with core-shell structure, where the particle body contains carrier materials and the shell contains smoking agents. This segmentation allows for controlled release and improved smoke production while maintaining smoking quality.
Solution Approach 2:
Different regions of the tobacco particle have different functions: the particle body (core) contains carrier materials for structural support and controlled release, while the shell contains smoking agents for smoke generation. This local quality differentiation improves both smoke production and smoking uniformity.
2Stability of the object's composition
If tobacco particles are dried to reduce moisture, then storage stability improves, but tobacco tar leakage occurs and usability is affected
Solution Approach 1:
A shell structure is formed around the particle body, containing smoking agents and preventing tobacco tar leakage. The shell acts as a barrier that maintains storage stability while preventing harmful substance leakage during use.
Solution Approach 2:
The shell is nested around the particle body, creating a core-shell structure where the inner particle body contains carrier materials and the outer shell contains smoking agents. This nested structure prevents leakage while maintaining stability.
3Quantity of substance
If smoking agents are uniformly distributed in tobacco particles, then smoke production increases, but manufacturing complexity increases
Solution Approach 1:
Carrier materials are prepared in advance as particle bodies, and smoking agents are subsequently loaded onto these pre-formed carriers. This preliminary action simplifies the manufacturing process while ensuring uniform distribution of smoking agents for improved smoke production.
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 solution provides a smoking body with improved smoke production, stability, and uniformity, along with effective prevention of tobacco tar leakage, resulting in a more satisfying smoking experience.
Implementation Method 1
the carrier is a porous material... the porous material has high porosity, so a lot of the smoking agent is loaded
Implementation Method 2
the carrier carries a smoking agent... the smoking agent includes a tobacco extract and/or an atomizer
Implementation Method 3
with the design of shells on the particle bodies, the smoking agent can be isolated from the outside to solve the problem of leakage
