Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-layer smokable material structure is used, then the device complexity is low, but the aerosol generation consistency and speed are insufficient
Solution Approach 1:
The smokable material is divided into two distinct layers with different properties. The first layer contains larger particles that heat slowly and provide sustained volatilization, while the second layer contains smaller particles that heat quickly and provide rapid aerosol generation. This segmentation allows each layer to perform its specific function, ensuring consistent and reliable aerosol generation throughout the heating process.
Solution Approach 2:
Different regions of the smokable material are given different local qualities in terms of particle size and heating characteristics. The first layer is positioned closer to the heater with larger particles for slow heating, while the second layer is positioned farther away with smaller particles for quick heating. This local differentiation ensures that both layers contribute optimally to aerosol generation at different stages of heating.
2Productivity
If uniform particle size smokable material is used, then the manufacturing precision is high, but the volatilization speed and aerosol generation efficiency are delayed
Solution Approach 1:
The smokable material is segmented into two particle size categories distributed across two layers. The first layer uses larger particles (lower manufacturing precision) for slow, sustained heating, while the second layer uses smaller particles (higher manufacturing precision) for rapid heating and quick aerosol generation. This segmentation allows the system to achieve high productivity by utilizing the fast-heating smaller particles while maintaining acceptable manufacturing precision through controlled particle size distribution.
Solution Approach 2:
The patent changes the particle size parameter across different layers to optimize heating performance. By varying particle size from the first layer to the second layer, the system achieves different heating rates that complement each other, improving overall aerosol generation efficiency while maintaining manufacturability through controlled particle size variations.
3Duration of action of moving object
If quick-heating smokable material is used, then the aerosol generation speed is fast, but the duration of action is short
Solution Approach 1:
The smokable material is segmented into two functional layers: the first layer with larger particles provides slow heating and extended duration of action, while the second layer with smaller particles provides fast heating and rapid aerosol generation. This segmentation allows the system to achieve both fast initial response and prolonged duration by combining the complementary characteristics of the two layers.
Solution Approach 2:
The patent merges the functions of quick-heating and long-duration materials into a single integrated smokable material structure. The first and second layers work together synergistically, with the smaller particles in the second layer providing rapid initial heating and the larger particles in the first layer sustaining the heating process over an extended period, thereby achieving both fast speed and long duration simultaneously.
