Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional heating assembly structure is used, then the device is simple in structure, but it cannot operate in different atomization modes
Solution Approach 1:
The base is segmented into two distinct pore systems: disordered pores for low-superheat atomization and through pores for high-superheat atomization. This segmentation allows each pore type to serve specific atomization modes, enabling the heating assembly to adapt to different atomization requirements without requiring multiple separate heating devices.
Solution Approach 2:
The heating assembly achieves multi-functionality by integrating both disordered pores and through pores into a single base structure. The same heating assembly can operate in low-superheat mode using disordered pores or switch to high-superheat mode using through pores, eliminating the need for separate heating devices for different atomization modes.
2Adaptability or versatility
If only through pores are provided in the base, then high-superheat atomization is achieved, but low-superheat atomization capability is lost
Solution Approach 1:
The patent merges two different pore structures (disordered pores and through pores) into a single integrated base. The disordered pores extend from the first surface to the second surface and contain cavities, while through pores pass directly through the base. Both pore types work together within the same heating assembly, allowing it to provide both low-superheat and high-superheat atomization capabilities simultaneously.
3Strength
If the porous base thickness is increased, then structural strength is improved, but liquid supply efficiency to the heating element decreases
Solution Approach 1:
The patent introduces a vertical dimension to liquid supply by creating through pores that pass completely through the base thickness. This allows liquid to be supplied directly to the heating element from both the first and second surfaces, effectively bypassing the thickness barrier. The disordered pores within the base provide additional liquid distribution pathways, ensuring efficient liquid supply even when the base has sufficient thickness for structural strength.
