Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the electromagnetic heating coil is centered with the accommodating cavity, then the heat distribution is uniform, but the fogging speed is slow
Solution Approach 1:
The electromagnetic heating coil is intentionally misaligned with the accommodating cavity, creating an asymmetric configuration where the coil's axial center does not coincide with the cavity's longitudinal center. This asymmetric positioning concentrates the strongest magnetic induction and maximum heat at a specific location (high-temperature zone) rather than distributing it uniformly, enabling rapid fogging at the top of the aerosol-generating substrate.
Solution Approach 2:
The heating mechanism creates different temperature zones within the accommodating cavity by positioning the electromagnetic heating coil off-center. This results in a high-temperature zone at the top (where the coil is closest), a medium-temperature zone in the middle, and a low-temperature zone at the bottom. Each zone serves a specific function: the high-temperature zone enables rapid fogging, while the other zones ensure complete vaporization.
2Productivity
If the heating element heats the aerosol-generating substrate uniformly, then the vaporization is consistent, but the fogging speed is slow
Solution Approach 1:
The heating mechanism divides the accommodating cavity into three distinct temperature zones (high, medium, and low) along the longitudinal direction. This segmentation allows different regions to perform different functions: the high-temperature zone rapidly vaporizes the top of the substrate for quick fogging, while the medium and low-temperature zones ensure complete and consistent vaporization of the entire substrate, maintaining reliability.
3Speed
If the electromagnetic heating coil is positioned to create a high-temperature zone at the top, then fogging speed increases, but the heat distribution becomes uneven
Solution Approach 1:
The invention intentionally changes the temperature distribution parameter from uniform to non-uniform by misaligning the electromagnetic heating coil. This creates a deliberate temperature gradient along the longitudinal direction, with the highest temperature at the top (high-temperature zone) and progressively lower temperatures toward the bottom. This parameter change enables rapid fogging while the gradient structure ensures complete vaporization throughout.

AI summary
The present disclosure relates to a heating mechanism (100) and an electronic vaporization device. The heating mechanism (100) includes: a heating element (10) configured in a longitudinal shape, the heating element (10) being provided with an accommodating cavity (11) extending along its longitudinal direction; and an electromagnetic heating coil (30) arranged around the heating element (10). In the longitudinal direction of the heating element (10), the axial center of the electromagnetic heating coil (30) is misaligned with the longitudinal center of the accommodating cavity (11). After the electromagnetic heating coil is energized, a heating electric field with the strongest magnetic induction can be formed at a position corresponding to its own axial center. For an aerosol-generating substrate in the accommodating cavity, the high-temperature field can be distributed to the top, so that the aerosol-generating substrate can be fogged rapidly from the top, with a large amount of smoke.
