Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single heat source is adopted to heat the substances to-be-atomized, then the device complexity is reduced, but local overheating occurs causing denaturation of substances

Engineering Contradiction:

Improveheating structure complexityVSAvoidlocal overheating

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The heating system is divided into multiple heating assemblies arranged along the axial direction, each with its own heating sleeve and magnet exciting coil. This segmentation distributes the heating function across multiple independent units, preventing concentration of thermal energy in a single location and thereby avoiding local overheating while maintaining manageable device complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each heating assembly is configured with different induction portion widths tailored to specific heating requirements at different axial positions. The induction portions have different widths in the axial direction, allowing each local region to receive customized heating intensity appropriate for its position, thus achieving uniform overall heating without local hot spots.

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If multiple heating assemblies with different induction portion widths are used, then even heating is achieved preventing denaturation, but the device complexity increases

Engineering Contradiction:

Improveeven heating distributionVSAvoidheating assembly structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The induction portions of different heating assemblies are deliberately designed with asymmetric width variations along the axial direction. This asymmetric configuration allows each heating assembly to contribute differently to the overall heating profile, with wider induction portions providing stronger heating where needed and narrower portions providing gentler heating, achieving even temperature distribution across the substance.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The heating control is extended from a single-point approach to a multi-dimensional approach by varying the induction portion width in the axial dimension. This dimensional variation creates a gradient heating pattern that naturally distributes heat more evenly through the substance, transforming a complex control problem into a geometric design solution.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Productivity

If a single heat source is used, then the manufacturing cost is reduced, but high atomization speed cannot be maintained without overheating

Engineering Contradiction:

Improveatomization speedVSAvoidlocal temperature control

Core Design Contradiction:

ProductivityVSTemperature

Solution Approach 1:

Multiple heating assemblies operate simultaneously and continuously along the axial direction, providing sustained and distributed heating action. This continuous multi-point heating ensures that the substance receives consistent thermal energy throughout the atomization process, enabling high atomization speeds to be maintained without creating localized temperature peaks that would cause overheating.

Inventive Principle:

Principle #20Continuity of useful action
