Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single resistive heating element is used, then the device structure is simple, but the control precision and efficiency of aerosol generation are limited
Solution Approach 1:
The heating layer is divided into multiple independent resistive heating elements (first heating element, second heating element, etc.), each capable of being individually controlled. This segmentation allows precise control over different regions of the aerosol generating material, improving aerosol generation precision while maintaining reasonable device complexity through modular design
2Productivity
If multiple heating elements are used, then the aerosol generation efficiency is improved, but the electrical contact configuration becomes more complex
Solution Approach 1:
Multiple heating elements are integrated into a single heating layer structure, sharing common electrical contacts where applicable. The first and second heating elements are positioned adjacent to each other within the same heating layer, allowing efficient electrical connection while maintaining independent heating capability, thus improving aerosol generation efficiency without proportionally increasing electrical contact complexity
3Productivity
If the heating elements are closely positioned, then the aerosol generation is more efficient, but the risk of thermal interference increases
Solution Approach 1:
Each heating element is designed to heat a specific portion of the aerosol generating material with localized thermal control. The first heating element heats a first portion while the second heating element heats a second portion, allowing efficient aerosol generation from multiple regions simultaneously while minimizing thermal interference through spatial separation of heating zones
