Non-combustible Smoking Device with Dual Heating Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic vaping devices lack an effective method to combine the vaporization of pre-vapor formulations with the delivery of tobacco aroma without combustion, which is essential for a non-combustible smoking experience.
Innovation Solution
A non-combustible smoking device design featuring a pre-vapor formulation reservoir, a heating element for vaporizing the formulation, and a tobacco heating element that generates aroma, where the vapor is passed through a tobacco housing to combine the flavors, using a detachable cartridge system to ensure cleanliness and prevent cross-contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single heating element is used to vaporize pre-vapor formulation, then the device structure is simple, but the tobacco aroma delivery is insufficient
Solution Approach 1:
The heating system is divided into two separate heating elements: a first heating element for vaporizing the pre-vapor formulation and a second heating element for heating tobacco to generate aroma. This segmentation allows each heating element to be optimized for its specific function, ensuring reliable tobacco aroma delivery while maintaining reasonable structural complexity
Solution Approach 2:
The patent combines two distinct heating functions (vaporization and aroma generation) into a single integrated device. The first heating element vaporizes the pre-vapor formulation while the second heating element simultaneously heats tobacco to generate aroma, merging multiple functions into one unified system
2Reliability
If tobacco is directly heated in contact with pre-vapor formulation, then the flavor combination is effective, but cross-contamination and clogging occur
Solution Approach 1:
The patent extracts tobacco from direct contact with the pre-vapor formulation by placing it in a separate compartment. The second heating element heats tobacco independently, and the generated aroma is delivered separately, preventing cross-contamination and clogging while maintaining effective flavor combination through coordinated delivery
Solution Approach 2:
The tobacco heating system is nested within the device structure in a way that allows independent operation. The second heating element and tobacco are contained in a separate compartment that is integrated into the overall device, enabling simultaneous vaporization and aroma generation without direct contact between the two materials
3Device complexity
If a fixed cartridge system is used, then the device structure is simple, but cleanliness and hygiene are compromised
Solution Approach 1:
The cartridge system is designed to be replaceable and detachable, allowing users to remove and replace cartridges as needed. This dynamic design enables easy cleaning and maintenance, improving hygiene while maintaining simple device structure through modular architecture
