Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a spiral heating wire is used in the atomizing head, then the atomizer can function, but the heating efficiency is low and the atomizing effect is poor
Solution Approach 1:
The patent replaces the traditional spiral heating wire (mechanical/coil structure) with a heating sheet that has a large surface area contact with the liquid guiding component. This substitution transforms the heating mechanism from a concentrated coil to a distributed sheet structure, achieving better heat distribution and higher heating efficiency while maintaining stable atomization.
Solution Approach 2:
The patent transitions from a one-dimensional spiral wire structure to a two-dimensional heating sheet structure. The heating sheet provides a larger surface area in contact with the liquid guiding component, enabling more efficient heat transfer and improved atomizing effect through increased dimensional contact area.
2Reliability
If an atomizing head with spiral heating wire is used, then the atomizer can operate, but the structure is complicated and the manufacturing cost is high
Solution Approach 1:
The patent extracts the heating element from the traditional integrated atomizing head structure and separates it into a standalone heating sheet that can be independently replaced. This extraction simplifies the overall atomizer structure, reducing manufacturing complexity and cost while maintaining operational reliability.
Solution Approach 2:
The patent segments the atomizer into distinct functional components: the liquid storage cup, the microporous liquid conducting body, the liquid guiding component, and the heating sheet. This segmentation allows for simpler manufacturing of individual parts and easier assembly, reducing overall device complexity.
3Temperature
If a complex atomizing head structure is used, then heating can be achieved, but the aerosol volume is unstable
Solution Approach 1:
The patent applies local quality by designing the heating sheet to have uniform thermal properties across its surface, ensuring consistent heating across the entire contact area with the liquid guiding component. This uniform local heating quality prevents hot spots and ensures stable aerosol generation throughout operation.
