Non-Combustion Suction Tobacco Product for Stable Nicotine Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-combustion suction type tobacco products experience a rapid reduction in nicotine delivery with increased puffing, leading to an uncomfortable user experience and a perceived shorter usable period.
Innovation Solution
Incorporation of a stabilizer with a solubility parameter distance of 12 or less and vapor pressure of 0.1 mmHg or less, such as medium-chain triglyceride, tributyl citrate, benzyl benzoate, or ethyl laurate, into tobacco particles to stabilize nicotine delivery over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If tobacco particles are used without stabilizer, then initial nicotine delivery is achieved, but nicotine delivery amount rapidly reduces with increased puffing
Solution Approach 1:
A stabilizer substance is introduced as an intermediary component in the tobacco particles. This stabilizer mediates between the nicotine and the external environment, controlling the release rate and preventing rapid depletion. The stabilizer acts as a buffer that maintains consistent nicotine delivery over extended puffing periods, resolving the contradiction between initial delivery effectiveness and long-term sustainability.
Solution Approach 2:
The invention changes the physical-chemical parameters of the tobacco particle system by incorporating a stabilizer with specific properties (solubility parameter distance of 12 or less and vapor pressure of 0.1 mmHg or less at 25°C). This parameter modification transforms the nicotine release characteristics from rapid depletion to controlled, sustained delivery, thereby extending the usable period while maintaining adequate nicotine delivery.
2Stability of the object's composition
If stabilizer content is increased to stabilize nicotine delivery, then nicotine stabilization improves, but particle lumping occurs making handling difficult
Solution Approach 1:
The invention identifies and controls critical parameters of the stabilizer substance, specifically requiring a solubility parameter distance of 12 or less and vapor pressure of 0.1 mmHg or less at 25°C. These parameter specifications ensure that the stabilizer provides effective nicotine stabilization without causing excessive particle aggregation or lumping, thus maintaining manufacturability while achieving delivery stability.
Solution Approach 2:
The tobacco particles are formulated as composite materials containing tobacco, stabilizer, and optionally other additives in specific proportions. This composite structure balances the stabilizing function with maintainable physical properties for handling. The composite formulation allows the stabilizer to be distributed uniformly without causing lumping, resolving the contradiction between stabilization effectiveness and manufacturing ease.
