Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional cigarettes are used, then smoking function is provided, but health risks and fire hazards occur
Solution Approach 1:
The patent converts the harmful combustion process into a beneficial vaporization process. Instead of burning tobacco which produces harmful smoke and fire hazards, the invention uses an electric heating element to vaporize liquid, eliminating combustion-related dangers while maintaining the inhalation function. The liquid reservoir replaces the combustible tobacco, and the heating element provides controlled vaporization without fire risk.
Solution Approach 2:
The patent replaces the mechanical combustion system with an electrical vaporization system. The traditional cigarette relies on chemical combustion (mechanical/chemical process), while the invention uses an electric heating element to vaporize liquid, substituting the combustion mechanism with an electrical heating mechanism that is more controllable and safer.
2Productivity
If liquid velocity is increased for efficient vaporization, then vaporization efficiency improves, but flavor quality deteriorates
Solution Approach 1:
The patent applies local quality by creating different flow conditions in different parts of the liquid delivery system. The liquid flows at higher velocity through the main channel for efficient supply, but slows down in the vaporization chamber where it contacts the heating element, allowing proper atomization and flavor preservation. This localized flow control optimizes both efficiency and quality.
Solution Approach 2:
The patent uses dynamic flow control where the liquid velocity is adjusted based on the operational requirements. The system allows liquid to flow at varying speeds depending on the heating power and inhalation demand, optimizing the balance between vaporization efficiency and flavor quality through dynamic adaptation rather than fixed flow rate.
3Power
If power delivery is increased for better vaporization, then vaporization performance improves, but energy consumption increases
Solution Approach 1:
The patent employs periodic or pulsed power delivery to the heating element rather than continuous high power. The system activates heating in cycles that match the inhalation pattern, providing high power during inhalation for effective vaporization, then reducing or stopping power delivery during non-inhalation periods, thus optimizing performance while controlling energy consumption.
