Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional heating element with limited surface area is used, then the device complexity is reduced, but the atomization effect deteriorates due to poor liquid distribution and large particle sizes
Solution Approach 1:
The heating element transitions from a traditional wire or coil structure to a plate-shaped structure with micropores. This dimensional change from 1D/2D to a 3D plate structure with porous architecture dramatically increases the effective heating surface area, allowing for much better liquid distribution and atomization performance.
Solution Approach 2:
The heating plate incorporates micropores throughout its structure, creating a porous material that enables capillary action for liquid absorption and distribution. These micropores allow liquid to be drawn into the heating element and distributed across the entire heating surface, significantly improving atomization effect and producing finer particles.
2Manufacturing precision
If a plate-shaped heating plate with large surface area is used, then the atomization effect is improved, but the heat loss increases due to greater exposed surface area
Solution Approach 1:
The microporous structure of the heating plate enables efficient liquid distribution across the entire surface, ensuring that heat is transferred to liquid throughout the plate rather than being lost to the surrounding air. This maximizes the useful heating function while minimizing waste heat loss.
Solution Approach 2:
The heating plate's microporous structure enables self-absorption of liquid through capillary action, eliminating the need for external liquid delivery mechanisms. The liquid automatically distributes itself across the heating surface, ensuring continuous efficient atomization without additional energy input for liquid pumping or distribution.
3Manufacturing precision
If the heating plate is made with micropores for better liquid absorption, then the atomization uniformity is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The microporous structure can be fabricated using established ceramic or metal foam technologies, which provide uniform pore distributions through controlled manufacturing processes. These mature techniques enable consistent micropore formation across the heating plate surface, achieving uniform atomization without requiring excessively complex or precise manufacturing steps.
Solution Approach 2:
The heating plate can be constructed as a composite material combining a porous substrate with a conductive heating layer or coating. This composite approach allows the porous structure to handle liquid distribution while the conductive layer provides efficient heating, dividing the functional requirements and simplifying the overall manufacturing process while maintaining atomization uniformity.
