Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If electrical energy is used to heat a solid aerosol-generating source, then aerosol can be produced without combustion, but significant amounts of incomplete combustion and pyrolysis products are still delivered
Solution Approach 1:
The patent changes the temperature parameter by maintaining heating below the combustion threshold. The solid aerosol-generating source is heated to a temperature sufficient to produce aerosol but below the point where combustion or significant pyrolysis occurs, thereby reducing harmful products while maintaining aerosol delivery
Solution Approach 2:
The patent replaces the combustion-based heating mechanism with an electrical heating mechanism. Instead of using flame or combustion to generate heat, an electrical heater is used to heat the solid aerosol-generating source, providing precise temperature control that prevents combustion while still producing aerosol
2Temperature
If heat is applied to a solid aerosol-generating source, then aerosol is produced, but heat distribution is uneven and combustion occurs
Solution Approach 1:
The patent applies local quality by designing the heater to provide uniform heat distribution across the entire surface of the solid aerosol-generating source. The heater is configured to ensure that all regions of the source receive appropriate heat, preventing localized overheating that would lead to combustion while maintaining temperatures sufficient for aerosol generation throughout
Solution Approach 2:
The patent incorporates feedback control where a sensor monitors the temperature or heating conditions and provides information to a controller that adjusts the heater power accordingly. This feedback mechanism ensures heat is distributed evenly and prevents temperatures from rising to combustion levels
