Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generation devices face challenges in accurately monitoring the temperature of the susceptor due to interference from the magnetic field, which affects the accuracy of the sensing signal and the stability of the temperature measurement.
Innovation Solution
The proposed solution involves an aerosol generation device with a susceptor designed as a sheet shape extending in the axial direction of the cavity, incorporating an accommodation cavity to house a temperature sensor. This configuration isolates the magnetic field's impact on the sensing portion and integrates the susceptor and temperature sensor for improved stability and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the temperature sensor is closely attached to the susceptor to enable real-time monitoring, then the temperature monitoring capability is improved, but the sensing signal accuracy deteriorates due to magnetic field interference and induced current
Solution Approach 1:
The temperature sensor is nested within a cavity formed by the susceptor structure itself. The susceptor is designed with a first sheet-like body and a second sheet-like body that enclose a cavity space, allowing the temperature sensor to be positioned inside while remaining electrically isolated from the magnetic field interference that affects external sensors.
Solution Approach 2:
The cavity structure acts as an intermediary barrier between the temperature sensor and the magnetic field. This physical enclosure mediates the interaction, allowing the sensor to detect temperature accurately while blocking the harmful magnetic field interference and induced currents that would otherwise corrupt the sensing signal.
2Ease of operation
If the temperature sensor is placed outside the susceptor for easy access, then the installation is simplified, but the magnetic field interference directly affects the sensing signal
Solution Approach 1:
The temperature sensor integration is merged with the susceptor structure itself. The cavity for housing the temperature sensor is formed as an integral part of the susceptor's sheet-like bodies, combining the heating function and temperature sensing function into a single unified component that maintains both ease of installation and measurement accuracy.
3Ease of manufacture
If the susceptor is made as a simple single-piece structure for ease of manufacture, then the manufacturing complexity is reduced, but the temperature sensor accommodation space is insufficient
Solution Approach 1:
The susceptor is segmented into a first sheet-like body and a second sheet-like body that are connected together. This segmentation allows the formation of a cavity between the two bodies, creating accommodation space for the temperature sensor while maintaining a relatively simple manufacturing process using standard sheet metal forming techniques.
