Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ceramic porous material is used as oil conducting material with printed heating slurry or embedded metal resistive heating body, then the atomizing function is achieved, but the ceramic molding process becomes complex with low yield and poor consistency

Engineering Contradiction:
Improvequality consistencyVSAvoidceramic molding process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the heating element and atomizing bracket into a single integrated component. The resistive heating element is directly formed on the atomizing bracket, eliminating the need for separate ceramic molding processes and multiple assembly steps. This integration simplifies the manufacturing process while improving quality consistency.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent replaces the traditional ceramic molding process with a direct formation method. Instead of using complex ceramic molding, printing, and embedding processes, the heating element is directly formed on the atomizing bracket structure, substituting a simplified mechanical formation process for the complex ceramic manufacturing system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If ceramic porous material is used for oil conduction, then atomization is achieved, but the oil conductivity is poor leading to burning smell

Engineering Contradiction:

Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent uses a composite structure combining the atomizing bracket material with the resistive heating element. This composite design improves oil conductivity compared to traditional ceramic materials, ensuring adequate oil supply to the heating surface and preventing burning smell during atomization.

Inventive Principle:
Principle #40Composite materials

3Ease of operation

If transverse cotton core is wrapped with spiral resistive heating wire, then atomization is achieved, but the cotton core deforms easily making assembly difficult

Engineering Contradiction:

Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent merges the heating element and atomizing bracket into a single integrated component. The resistive heating element is directly formed on the atomizing bracket, eliminating the need for separate cotton cores and wrapped heating wires. This integration eliminates assembly difficulties and structural deformation issues.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of manufacture

If vertical cotton core with oil guide cotton is used, then atomization is achieved, but the complex assembly results in high product cost

Engineering Contradiction:
Improveproduct costVSAvoidassembly complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges multiple components (atomizing bracket, heating element, and oil guide structure) into a single integrated atomizing assembly. This eliminates the need for separate vertical cotton core and oil guide cotton assembly, reducing both assembly complexity and product cost.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated atomizing bracket structure incorporates the oil guide function directly into its design. The bracket itself serves as both the structural support and the oil conduction pathway, eliminating the need for separate oil guide components and simplifying manufacturing.

Inventive Principle:
Principle #25Self-service
