Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a heating element and a stirring element are integrated into a single structure, then the device complexity is reduced, but the reliability decreases due to increased wear and tear on the stirring element

Engineering Contradiction:

Improvestructure complexityVSAvoidstirring element reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent divides the aerosol generation system into separate functional modules: a heating element housed in a heating chamber and a stirring element housed in a separate stirring chamber. This segmentation allows each element to perform its function independently without mechanical wear between them, while the controller coordinates their operations to achieve the desired aerosol generation effect.

Inventive Principle:

Principle #1Segmentation

2Reliability

If magnetic elements are used to drive the stirring element, then the mechanical contact and wear are reduced, but the device complexity increases due to additional magnetic components

Engineering Contradiction:

Improvestirring element durabilityVSAvoidmagnetic element configuration

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces direct mechanical drive mechanisms with a magnetic field-based drive system. A magnetic element is positioned adjacent to the stirring element, and by varying the magnetization of the magnetic element, the stirring element is rotated without physical contact. This eliminates mechanical wear while providing precise control over stirring speed and direction through electrical control of the magnetic field.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If the stirring element is driven by direct mechanical contact, then the control is simple, but the wear and tear increases reducing reliability

Engineering Contradiction:

Improvestirring control simplicityVSAvoidstirring element lifespan

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces mechanical contact-based stirring control with magnetic field control. The controller varies the magnetization of the magnetic element to control the rotation of the stirring element, providing simple electrical control without mechanical wear. This allows for precise control of stirring speed and direction while eliminating the wear associated with mechanical gears, belts, or direct-contact motors.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
