Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat-not-burn electronic atomization devices have a fixed temperature field that leads to uneven aerosol release and potential scorching of the substrate, and their segmental heating designs are bulky and difficult to achieve small, light, and thin products.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed temperature field is used to heat the aerosol-forming substrate, then the heating structure is simple, but the aerosol release is uneven and the substrate may be scorched
Solution Approach 1:
The patent applies the dynamics principle by making the heating element movable instead of fixed. The heating element can move along the aerosol-forming substrate to create a dynamic heating process, which allows for more uniform aerosol release and prevents scorching while maintaining relatively simple device structure.
2Stability of the object's composition
If segmental-type heating device with multiple segments is used, then the heating continuity is improved, but the device size and weight increase
Solution Approach 1:
The patent applies segmentation by dividing the heating process into multiple stages through a single movable heating element rather than using multiple simultaneous heating segments. The heating element sequentially heats different portions of the substrate, achieving continuous heating effect while maintaining compact device size and low weight.
3Stability of the object's composition
If segmental-type heating device with multiple segments is used, then the heating continuity is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple heating segments into a single movable heating element. This single element performs the function of multiple segments by moving sequentially along the substrate, thereby achieving continuous heating while reducing device complexity and eliminating the need for complex multi-segment control systems.
4Power
If a fixed temperature field covers a large area, then the heating capacity is high, but the aerosol release attenuates in the later stage
Solution Approach 1:
The patent uses a dynamic heating approach where the heating element moves along the substrate, concentrating heat in a smaller active zone at any given time. This maintains high heating capacity while extending the overall aerosol release duration by sequentially processing different portions of the substrate, preventing early release attenuation.
