Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a single heating element is used, then the device structure is simple, but the heating uniformity and aerosol generation control are insufficient

Engineering Contradiction:
Improveheating uniformityVSAvoidheating assembly structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The heating assembly is divided into multiple discrete heating portions (first, second, third heating portions) arranged in a specific pattern. Each heating portion can be independently controlled, allowing precise thermal management of different regions of the aerosol generating material to achieve uniform heating and consistent aerosol generation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different heating portions are positioned to contact different regions of the aerosol generating material, enabling localized heating control. This allows specific areas to be heated to optimal temperatures for aerosol generation while maintaining overall heating uniformity across the entire material.

Inventive Principle:
Principle #3Local quality

2Productivity

If heating portions are added to improve heating efficiency, then aerosol generation improves, but airflow path obstruction increases

Engineering Contradiction:
Improveaerosol generation efficiencyVSAvoidairflow quantity
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The heating portions are designed with curved or rounded surfaces that conform to the shape of the aerosol generating material. This curved geometry allows better contact and heat transfer efficiency while creating smoother airflow paths that reduce turbulence and maintain adequate air flow through the heating zone.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The heating portions are arranged in a three-dimensional configuration within the heating zone, utilizing vertical and lateral spacing to create multiple heating levels. This spatial arrangement maximizes heating surface area contact with the material while preserving sufficient vertical clearance for airflow passage, thus maintaining both heating efficiency and airflow quantity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
