Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the atomizing core assembly is fixed into the connecting tube by riveting with twisting operations, then the atomizing core assembly can be securely fixed, but the assembly and disassembly process becomes inconvenient and structurally complex

Engineering Contradiction:

Improvesecure fixation of atomizing core assemblyVSAvoidassembly and disassembly convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The atomizing core assembly is divided into separate components: the atomizing core itself and the connecting tube with fixing structure. This segmentation allows the atomizing core to be easily inserted into and removed from the connecting tube without complex twisting operations, while still maintaining secure fixation through the integrated fixing structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fixing structure is merged with the connecting tube as an integrated component rather than a separate part. This merging eliminates the need for separate riveting operations and twisting maneuvers, allowing the atomizing core assembly to be securely fixed through a simplified insertion and locking mechanism that combines fixation and connection functions in one structure.

Inventive Principle:

Principle #5Merging (Combining)

2Reliability

If the atomizing core assembly requires twisting operations for assembly, then secure connection can be achieved, but the structural design difficulty increases

Engineering Contradiction:

Improvesecure connection of atomizing core assemblyVSAvoidstructural design complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Instead of requiring the atomizing core assembly to twist into place for secure connection, the design is inverted to provide a guiding structure and locking mechanism that automatically aligns and secures the assembly during simple insertion. The fixing structure engages with the connecting tube in a straightforward manner, eliminating the need for complex twisting motions and reducing structural design complexity.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of operation

If the atomizing core assembly is easily detachable, then assembly and disassembly becomes convenient, but the connection stability and leak prevention may be compromised

Engineering Contradiction:

Improvedetachability of atomizing assemblyVSAvoidconnection stability and leak prevention

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

A sealing structure acts as an intermediary element between the atomizing assembly and the connecting tube. This sealing structure maintains stable connection and prevents leakage while allowing for easy detachment. The sealing mechanism engages automatically during insertion and can be easily released when needed, providing both stability and ease of operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The fixing structure and sealing mechanism are designed to automatically engage and secure the atomizing assembly during simple insertion without requiring complex twisting operations. The self-aligning and self-locking characteristics of the fixing structure ensure stable connection and leak prevention while maintaining ease of detachment when required.

Inventive Principle:

Principle #25Self-service
