Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a single heating element is used to heat aerosol generating substances, then the device structure is simple, but the heating optimization for different substances is insufficient

Engineering Contradiction:

Improvedevice structure simplicityVSAvoidheating optimization

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The single heating element is divided into multiple discrete heating elements, each positioned in separate compartments. This segmentation allows independent heating optimization for different aerosol generating substances while maintaining a relatively simple overall device structure. Each heating element can be independently controlled to provide optimal heating conditions for its specific substance.

Inventive Principle:

Principle #1Segmentation

2Productivity

If heating temperature is increased to improve vaporization, then aerosol generation effectiveness is improved, but the risk of burning the substance increases

Engineering Contradiction:

Improveaerosol generation effectivenessVSAvoidburning risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

Different heating elements are designed with different heating characteristics tailored to the specific substances they heat. Each heating element provides locally optimized heating conditions appropriate for its specific aerosol generating substance, preventing overheating and burning while ensuring effective vaporization. This allows precise control of heating temperature at each location.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The heating elements are designed to provide dynamic heating control, allowing the heating temperature to be adjusted based on the specific substance and desired aerosol generation rate. This dynamic control prevents burning by avoiding excessive temperature while maintaining sufficient heat for effective vaporization.

Inventive Principle:

Principle #15Dynamics

3Manufacturing precision

If multiple compartments with individual heating are implemented, then heating optimization for different substances is achieved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The device is segmented into multiple compartments with individual heating elements, allowing independent optimization for different substances. This segmentation is implemented in a modular manner that maintains structural clarity and does not excessively increase overall device complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The multiple compartment design serves multiple functions simultaneously: it allows heating optimization for different substances, provides physical separation to prevent contamination, and enables independent control of heating parameters for each substance. This multi-functionality justifies the increased structural complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
