Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liquid tobacco with high viscosity is used, then aerosol generation is insufficient, but increasing heating temperature to reduce viscosity causes uncontrolled liquid flow and excessive liquid consumption
Solution Approach 1:
The atomizing core body is made of porous materials with specific pore diameters (80-150 μm) that control liquid tobacco flow through capillary forces. The porous structure allows precise regulation of liquid conductance while maintaining stable atomization, preventing both insufficient aerosol generation and excessive liquid consumption
Solution Approach 2:
The patent changes physical parameters including pore diameter (80-150 μm), hole diameter (50-200 μm), and heating temperature (200-400°C) to optimize the balance between viscosity reduction and liquid flow control. These parameter adjustments enable controlled liquid conductance while maintaining efficient aerosol generation
2Speed
If heating temperature is increased to reduce liquid viscosity, then liquid conducting velocity increases, but control of liquid amount becomes inconvenient and liquid consumption increases
Solution Approach 1:
The porous body with controlled pore diameter (80-150 μm) provides capillary resistance that regulates liquid flow rate independently of heating temperature. This allows the liquid conducting velocity to be controlled through pore size selection rather than solely through temperature adjustment, improving ease of operation
Solution Approach 2:
The porous body acts as an intermediary between the liquid storage and atomization channels, mediating the liquid flow through capillary forces. This intermediary structure decouples the relationship between heating temperature and liquid flow rate, enabling independent control of each parameter
3Productivity
If liquid conducting holes are added to the porous body, then liquid conductance is improved, but device complexity increases
Solution Approach 1:
The liquid conducting holes are integrated directly into the porous body structure, merging the liquid conduction function with the atomization core. This eliminates the need for separate liquid delivery components, improving liquid conductance while avoiding increased device complexity
Solution Approach 2:
The porous body with liquid conducting holes serves multiple functions simultaneously: it acts as the atomization core, provides liquid distribution through multiple holes, and controls flow rate through capillary forces. This multi-functionality improves liquid conductance without adding separate components
