Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional atomizer design is used, then the atomizer structure is simple, but leakage liquid can reach the power supply causing corrosion and safety hazards

Engineering Contradiction:

Improvesafety of power supplyVSAvoidstructure of atomizer

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The atomizer is divided into functionally independent sections: an atomizing cavity for aerosol generation, a storage portion for collecting leakage liquid, and a sealing member with drainage grooves for liquid management. This segmentation isolates the power supply from leakage liquid while maintaining structural organization

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sealing member acts as an intermediary component between the atomizing core and the base. It includes drainage grooves that intercept and redirect leakage liquid into the storage portion, preventing direct contact with the power supply while maintaining the functional connection between components

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If no liquid management structure is added, then the atomizer structure remains simple, but leakage liquid will leak out and corrode the power supply

Engineering Contradiction:

Improvecorrosion to power supplyVSAvoidsealing and drainage structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The drainage grooves on the sealing member and inclined surface on the base convert the harmful leakage liquid into a controlled flow that is redirected into the storage portion. The liquid that would otherwise cause corrosion is now captured and contained, transforming a safety hazard into a managed byproduct

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The sealing member functions as a flexible barrier between the atomizing cavity and the external environment. It seals the connection while incorporating drainage pathways that allow controlled liquid management, preventing uncontrolled leakage to the power supply

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If a sealing member with drainage grooves is added, then leakage liquid is prevented from reaching the power supply, but the atomizer structure becomes more complex

Engineering Contradiction:

Improveprotection of power supplyVSAvoidsealing member structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The sealing member performs multiple functions simultaneously: it seals the connection between the atomizing core and base, provides drainage pathways for leakage liquid through grooves, and directs liquid flow toward the storage portion. This multi-functionality reduces the need for separate components while maintaining protection

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Object-generated harmful factors

If an inclined surface and storage portion are added, then leakage liquid is contained within the atomizer, but the manufacturing complexity increases

Engineering Contradiction:

Improveleakage liquid containmentVSAvoidatomizer assembly

Core Design Contradiction:

Object-generated harmful factorsVSEase of manufacture

Solution Approach 1:

The storage portion is integrated into the base structure, and the drainage grooves are formed as continuous features on the sealing member. This merging of functions into unified components simplifies the assembly process while maintaining effective liquid containment capabilities

Inventive Principle:

Principle #5Merging (Combining)
