Removable Inductive Susceptor for Cigarette Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing induction heating methods for cigarettes face challenges in temperature control due to the difficulty in measuring the temperature of magnetic materials within the cigarette, leading to inconsistent aerosol and flavor delivery.
Innovation Solution
An apparatus and system that includes a susceptor formed in an elongated structure outside the cigarette, which is heated by an alternating magnetic field generated by a coil, allowing for precise temperature control and easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a magnetic material is included inside the cigarette for induction heating, then the cigarette can be heated by receiving a magnetic field from the outside, but it becomes difficult to measure the temperature of the magnetic material and control the heating temperature
Solution Approach 1:
The magnetic material (susceptor) is extracted from the cigarette and placed in the apparatus instead. The susceptor is positioned in the heating chamber and heated by the alternating magnetic field, then transfers heat to the cigarette. This separation allows direct temperature measurement of the susceptor while maintaining the induction heating function.
Solution Approach 2:
The susceptor acts as an intermediary between the alternating magnetic field and the cigarette. It receives the magnetic field energy, converts it to heat, and transfers that heat to the cigarette. This intermediary approach enables temperature control of the susceptor while indirectly heating the cigarette.
2Ease of manufacture
If a magnetic material is included inside the cigarette for induction heating, then the cigarette can be heated by receiving a magnetic field from the outside, but inconsistent manufacturing of cigarettes leads to different aerosol and flavor delivery
Solution Approach 1:
The magnetic material is extracted from the cigarette and placed in the apparatus. This separates the heating function from the cigarette manufacturing variability, allowing consistent heating conditions in the apparatus while maintaining cigarette manufacturing flexibility.
Solution Approach 2:
Temperature sensors monitor the susceptor temperature in real-time, and the control unit adjusts the alternating current to the coil based on this feedback. This closed-loop control ensures consistent heating temperature regardless of cigarette manufacturing variations.
3Adaptability or versatility
If the susceptor is included in the cigarette, then the heating function is integrated with the cigarette, but the apparatus becomes difficult to clean and maintain
Solution Approach 1:
The susceptor is extracted from the cigarette and placed in the apparatus as a separate, removable component. This allows the susceptor and heating chamber to be easily removed and cleaned, while still providing the integrated heating function during operation.
Solution Approach 2:
The heating system is segmented into separate components: the susceptor, the coil, and the heating chamber. This segmentation allows each component to be independently accessed, cleaned, and maintained, improving ease of repair while maintaining functional integration during use.
