Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the atomizer is powered on at the bottom with lower air intake, then the atomization core can be connected to the battery box, but liquid leakage through the air inlet occurs and assembly becomes complicated

Engineering Contradiction:
Improveconnection reliabilityVSAvoidliquid leakage
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent inverts the conventional bottom-power-on configuration to top-power-on configuration. The atomization core is positioned at the top of the atomizer body, with the heating element and air inlet both located at the top. This inversion eliminates the liquid leakage problem through the air inlet while simplifying the overall assembly structure.

Inventive Principle:
Principle #13The other way round (Inversion)

2Reliability

If the atomization core is arranged at the bottom for lower power-on, then connection to battery box is achieved, but assembly difficulty increases and liquid leakage cannot be avoided

Engineering Contradiction:
Improveelectrical connectionVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the atomization core, heating element, and air inlet into a single integrated top-positioned assembly. The atomization core body integrates the heating element within it, and the air inlet is directly formed on the atomization core body at the top. This merging eliminates the need for separate bottom connections and reduces assembly complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If lower air intake is used for bottom power-on, then battery box connection is enabled, but liquid leakage through air inlet hole occurs

Engineering Contradiction:
Improvepower-on operationVSAvoide-liquid leakage
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent inverts the air intake location from the bottom to the top, positioning it directly on the atomization core body at the top. This ensures that air intake occurs above the e-liquid level, preventing liquid leakage through the air inlet while maintaining ease of operation for power-on.

Inventive Principle:
Principle #13The other way round (Inversion)
