Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tobacco roasters face issues with metal cup staining and difficulty in cleaning due to direct contact with tobacco material, and lack of features for preventing granulate inhalation and leakage.
Innovation Solution
A tobacco roaster design incorporating a high frequency heating module with a magnetic induction coil and a movable push rod assembly, featuring a glass cup for tobacco material, a glass cover with air circulation holes, and thermal insulation gaskets, allowing for easy cleaning and granulate filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed metal cup is used to accommodate tobacco material, then the heating function is achieved, but the metal cup cannot be removed for cleaning and is easily stained
Solution Approach 1:
The roasting chamber is segmented into a removable metal cup and a fixed housing. The metal cup can be detached from the housing for cleaning, while the housing remains fixed. This segmentation allows the staining-prone metal cup to be separated and cleaned independently without disassembling the entire device.
Solution Approach 2:
The metal cup is extracted as a removable component from the fixed housing. The cup can be taken out for cleaning and replacement, while the housing structure remains in place. This extraction solves the cleaning problem by allowing the metal cup to be removed and washed externally.
2Object-affected harmful factors
If a glass cup is used to accommodate tobacco material, then environmental benefits are achieved by reducing direct metal contact, but the structural complexity increases
Solution Approach 1:
The glass cup is nested inside the metal cup, creating a dual-cup structure. The glass cup holds the tobacco material and is placed within the removable metal cup, which in turn fits into the fixed housing. This nesting arrangement reduces direct contact between metal and tobacco while maintaining a compact structure.
3Object-affected harmful factors
If a glass cover with through holes is used for air circulation, then filtration of granulates is achieved, but the structural complexity increases
Solution Approach 1:
The glass cover is designed with multiple through holes that act as a physical filter. As air and vapor pass through these holes during the roasting process, granulates are trapped by the glass surface while allowing breathable vapor to pass through. This porous structure provides filtration without requiring additional filter components.
4Temperature
If thermal insulation gaskets are added to the magnetic induction coil, then thermal insulation is improved, but the device complexity increases
Solution Approach 1:
Silicone thermal insulation gaskets are used to wrap around the magnetic induction coil. These flexible gaskets provide thermal insulation by creating a barrier between the heated coil and surrounding components. The gaskets can be easily installed and removed, providing insulation without complex structural modifications.

AI summary
A tobacco roaster includes a high frequency heating module and a pushing assembly. The high frequency heating module includes a metal cup and a magnetic induction coil. The metal cup is disposed in the magnetic induction coil. When alternating current flows through the magnetic induction coil, an eddy current effect is formed in the metal cup and the metal cup is heated. The pushing assembly includes a push rod disposed below the metal cup. The push rod is movable to push the metal cup out of the tobacco roaster.
