Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If resistance heating mode is used to heat the aerosol generating substrate, then heating function is achieved, but uneven heating and excessive local temperature occur leading to dry burning and coking
Solution Approach 1:
The patent replaces resistance heating (thermal conduction) with microwave heating (electromagnetic radiation). The microwave heating unit generates microwave fields that directly heat the aerosol generating substrate through dielectric heating, eliminating the need for contact with heating elements that cause localized overheating and coking. This substitution of heating mechanism resolves the issue of uneven heating and harmful coke accumulation.
2Power
If microwave heating is used to heat the aerosol generating substrate, then heating efficiency is improved, but energy coupling efficiency is low and taste consistency is poor
Solution Approach 1:
The patent divides the aerosol generating substrate into multiple sections and uses a transmission assembly to move different sections through the microwave heating zone sequentially. This ensures that each section receives consistent microwave energy treatment, maintaining uniform heating conditions across all sections. The segmentation approach allows fresh, consistent material to be continuously presented to the microwave field, improving both energy coupling efficiency and taste consistency.
Solution Approach 2:
The patent introduces a transmission assembly that dynamically moves the aerosol generating substrate through the microwave heating unit. This dynamic movement ensures that material with consistent properties is continuously presented to the microwave field, maintaining stable energy coupling efficiency and consistent atomization taste throughout operation, unlike static heating methods where material properties degrade over time.
3Device complexity
If the aerosol generating substrate is stationary in the heating zone, then heating is simplified, but material properties change leading to inconsistent atomization taste over time
Solution Approach 1:
The patent transforms the stationary heating system into a dynamic one by introducing a transmission assembly that moves the aerosol generating substrate through the microwave heating zone. This dynamic approach ensures that fresh, consistent material is continuously presented to the heating field, maintaining stable atomization taste. The system complexity increases only minimally while achieving significant improvement in material consistency.

AI summary
An atomizer (10) and an electronic atomization device (100). The atomizer (10) comprises: an atomization assembly (20) inside which a conveying channel (21) and a microwave resonant cavity (23) are formed, the conveying channel (21) being used for accommodating an aerosol-generating substrate, and at least part of the conveying channel (21) being communicated with the microwave resonant cavity (23) to form an atomization region; and a transmission assembly (40), at least partially extending into the conveying channel (21) and controlled to drive the aerosol-generating substrate to move along the conveying channel (21). The conveying channel (21) is provided with an atomization region, the atomization region is communicated with the microwave resonant cavity (23) and located on a moving path of the aerosol-generating substrate, and the aerosol-generating substrate can be pushed by the transmission assembly (40) to move in the axial direction of the aerosol-generating substrate. In the whole atomization process, the next section of the aerosol-generating substrate that is not atomized is continuously conveyed to the atomization region, the materials and dielectric properties of the aerosol-generating substrate in the atomization region are basically consistent at different time periods, and atomization taste can be kept consistent all the time.
