Gas Heating Smoking Article Using Premixed Propane Flame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current e-cigarettes face issues with lithium battery overheating, limited tobacco extraction, and taste, which makes them unsuitable for long-term smokers, and traditional cigarettes produce harmful combustion products like tar and carbon monoxide.
Innovation Solution
A gas heating smoking article that uses a premixed gas flame to heat cigarette consumable items or aerosol generation consumable items, eliminating the need for batteries and minimizing harmful combustion products by using a combustion device with a step escapement system and heat collection unit to generate aerosol similar to traditional cigarettes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional cigarettes are used, then smokers experience the pleasant feeling from nicotine, but large quantities of tar and harmful substances are generated
Solution Approach 1:
The patent extracts and removes the harmful combustion process from the smoking experience. By using a gas heating device to heat tobacco extract solution instead of burning tobacco directly, the system separates the nicotine delivery function from the harmful combustion process, eliminating tar and carbon monoxide while preserving the nicotine effect.
Solution Approach 2:
The patent introduces a gas heating device as an intermediary between the tobacco extract solution and the user. This intermediary device heats the tobacco extract solution to generate aerosol without direct combustion, acting as a mediator that delivers nicotine while avoiding the harmful effects of traditional cigarette combustion.
2Object-affected harmful factors
If e-cigarettes are used, then tar and harmful combustion products are eliminated, but lithium battery overheating and limited tobacco extraction occur
Solution Approach 1:
The patent replaces the electrical heating system (battery-based) with a gas heating system. By substituting the mechanical/electrical energy source (lithium battery) with a chemical energy source (gas fuel), the system eliminates battery overheating risks while maintaining the ability to heat tobacco extract solution and generate aerosol.
3Object-generated harmful factors
If e-cigarettes use heating elements, then combustion is avoided, but heating element overheating causes carbon degradation
Solution Approach 1:
The patent introduces gas flame as an intermediary heating source instead of direct contact with heating elements. The gas flame transfers heat to the tobacco extract solution without requiring the solution to contact high-temperature heating surfaces, preventing carbon degradation and overheating issues.
Solution Approach 2:
The patent changes the heating method from direct contact heating (heating elements touching the solution) to radiant heating (gas flame heating the solution). This parameter change in the heating mechanism allows for effective heating without the temperature control issues and carbon degradation associated with direct heating elements.
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
This solution reduces harmful products from tobacco combustion, eliminates tar and carbon monoxide, and provides a safer, healthier smoking experience with a similar taste to traditional cigarettes, addressing the limitations of e-cigarettes and traditional smoking.
Implementation Method 1
combustion device using propane or butane premixed with air before combustion
Implementation Method 2
heat generated from the combustion is transferred to air path to heat air inside the air path
Implementation Method 3
the high-temperature air flow will vaporize the volatiles contained in the cut tobaccos and generate visible aerosol
