Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a temperature sensor made of metal material is used to sense the temperature of the susceptor, then the temperature sensing function is achieved, but the sensor generates induced current and heat in the alternating magnetic field, affecting sensing accuracy
Solution Approach 1:
The patent introduces a non-conductive material as an intermediary layer between the susceptor and the temperature sensor. This intermediary layer blocks the alternating magnetic field from directly acting on the temperature sensor, preventing induced current and heat generation while still allowing thermal energy to pass through to the sensor. This resolves the contradiction by protecting the sensor from magnetic interference while maintaining temperature sensing capability.
Solution Approach 2:
The patent employs a thin non-conductive film or layer as a protective barrier. This thin film is sufficient to block magnetic field penetration to the temperature sensor while being thin enough to allow thermal conduction. The flexible shell approach provides effective magnetic shielding without compromising thermal sensing functionality.
2Measurement precision
If the temperature sensor is closely attached to the susceptor for real-time monitoring, then temperature detection accuracy is improved, but the sensor is exposed to magnetic field interference and induced currents
Solution Approach 1:
The non-conductive intermediary layer serves as a mediator that maintains close thermal contact between the susceptor and temperature sensor while blocking magnetic field interference. This allows the sensor to be positioned closely for accurate real-time monitoring without direct exposure to harmful magnetic fields, thus improving both measurement precision and signal stability.
3Ease of manufacture
If the susceptor structure is simplified for easier manufacturing, then production cost is reduced, but the integration of temperature sensor and magnetic shielding becomes difficult
Solution Approach 1:
The patent merges the temperature sensor housing and magnetic shielding functions into a single integrated structure. The non-conductive material is incorporated directly into the susceptor design, combining multiple functions (structural support, thermal conduction, magnetic shielding) in one component. This reduces overall device complexity and simplifies manufacturing while maintaining sensor protection and functionality.

AI summary
A vapor generation device and a susceptor thereof are disclosed. The susceptor is in a blade shape extending in an axial direction of a cavity, and includes: a first part having a first size in a thickness direction, and a second part having a second size in the thickness direction, the second size being greater than the first size. An accommodation cavity extending in the axial direction is further arranged in the second part, and the accommodation cavity is configured to accommodate or encapsulate a temperature sensor that senses a temperature of the susceptor. The vapor generation device and the susceptor of this application encapsulates or accommodates the temperature sensor in the susceptor. Hence, a sensing part may be basically insulated from the impact of the magnetic field, and the susceptor and the temperature sensor may be integrated to increase stability of mounting and accuracy of temperature detecting.
