Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improveatomization mode adaptabilityVSAvoidheating assembly structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improveatomization temperature rangeVSAvoidpore structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

3Strength

If the porous base thickness is increased, then structural strength is improved, but liquid supply efficiency to the heating element decreases

Engineering Contradiction:
Improveporous base strengthVSAvoidliquid supply efficiency
Core Design Contradiction:
StrengthVSProductivity

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.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
