Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single vaporizer is used to generate aerosol, then the device structure is simple, but the device cannot convert between smokeless and smoke aerosol modes or adjust nicotine transport amount
Solution Approach 1:
The aerosol generating device is divided into a first vaporizer for generating smokeless aerosol and a second vaporizer for generating smoke aerosol. Each vaporizer is independently configured to perform specific functions, enabling mode conversion while maintaining manageable device complexity through functional segmentation.
Solution Approach 2:
The aerosol generating device is designed with multi-functionality to operate in different modes (smokeless and smoke aerosol) using two vaporizers with different heating temperatures. This universal design allows the single device to adapt to various user preferences and scenarios without requiring separate devices for each mode.
2Quantity of substance
If additional heaters are added to heat the aerosol generating article, then the nicotine transport amount can be increased, but the power consumption increases
Solution Approach 1:
The heating function for the aerosol generating article is merged into the existing vaporizer system. The first and second vaporizers not only generate aerosol but also indirectly heat the aerosol generating article through conduction, eliminating the need for separate heaters and reducing overall power consumption while maintaining nicotine transport efficiency.
Solution Approach 2:
The vaporizers serve dual purposes: generating aerosol and heating the aerosol generating article. The system uses its own heating elements (vaporizers) to perform the heating function that would otherwise require additional dedicated heaters, achieving self-service and optimizing energy utilization.
