Engineering Contradiction Analysis
1Loss of energy
If a conventional susceptor is used in electronic atomization devices, then the device can generate aerosol, but the heating efficiency of the susceptor is low
Solution Approach 1:
The susceptor uses a composite structure combining a ferromagnetic base body (magnetically conductive) with an electrical conductor layer bonded to its surface. This composite design allows the base body to concentrate magnetic flux while the conductor layer generates heat through eddy currents, achieving high heating efficiency and improved aerosol generation.
Solution Approach 2:
The electrical conductor is selectively bonded to specific regions of the base body surface, creating localized heating zones. The conductor may be positioned at the center or distributed across the surface, allowing targeted heat generation where it is most needed for efficient aerosol formation.
2Productivity
If more power is supplied to improve heating efficiency, then aerosol generation improves, but power consumption increases
Solution Approach 1:
The invention changes the physical parameters of the susceptor by introducing a ferromagnetic base body with high magnetic permeability. This increases the magnetic flux density in the susceptor, which enhances eddy current generation in the conductor layer, thereby improving heating efficiency and aerosol output while reducing the power required from the induction source.
