Cylindrical Heater Assembly for Uniform Cigarette Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cigarette-shaped electronic cigarettes fail to generate an abundant amount of vapor, leading to user dissatisfaction, and have difficulty in uniformly heating the solid stick due to the limited heated area and non-uniform heating methods.
Innovation Solution
A heater assembly for cigarette-shaped electronic cigarettes, comprising a smoking vapor generation part with a first heater having a hollow cylindrical shape and a heat insulating member, and a smoky vapor generation part with a second heater, which generates additional vapor by heating a liquid material, increasing the heated area and ensuring uniform heating of the cigarette.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a plate-shaped heater is partially inserted into the solid stick, then the device complexity is reduced, but the heated area is limited and uniform heating is difficult to achieve
Solution Approach 1:
The heater is designed with a cylindrical shape that matches the circular cross-section of the cigarette stick. This curved geometry allows the heater to wrap around and contact the stick along its entire circumference, maximizing the heated area and ensuring uniform heat distribution throughout the solid material.
2Device complexity
If a plate-shaped heater is partially inserted into the solid stick, then the device complexity is reduced, but the heating uniformity deteriorates
Solution Approach 1:
The cylindrical heater geometry enables uniform thermal contact with the cigarette stick by wrapping around it completely. This curved design ensures that heat is distributed evenly across the entire surface of the stick, eliminating the non-uniform heating problems associated with flat plate heaters that can only contact the stick at limited points.
3Device complexity
If only a first heater is used to heat the cigarette, then the device complexity is reduced, but the vapor generation amount is insufficient
Solution Approach 1:
The invention combines two heating systems into one device: a first heater that heats the solid cigarette material and a second heater that heats liquid material. These two heating functions work simultaneously to generate vapor, with the liquid heater supplementing the vapor production from the solid material heating, thereby increasing the total vapor generation amount without significantly increasing device complexity.
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 allows for increased vapor inhalation and exhalation, enhancing user satisfaction by generating a greater amount of vapor comparable to traditional cigarettes and ensuring uniform heating of the cigarette.
Implementation Method 1
a first heater configured to generate smoking vapor by heating a portion of a cigarette inserted thereinto
Implementation Method 2
