Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If pass-through holes are processed in a dense substrate through laser or micro-manufacturing, then liquid supply control and atomization amount control are improved, but hole blockage due to tobacco soot occurs, leading to local dry heating and shortened service life
Solution Approach 1:
The invention divides the liquid supply path into multiple independent pass-through holes instead of using a single hole or uniform porous structure. Each hole can be independently controlled and monitored, allowing the system to maintain precise liquid supply while reducing the risk of complete blockage. When one hole becomes blocked, others can continue to function, thereby extending the service life of the heating film.
Solution Approach 2:
The invention creates non-uniform hole distributions with different pore sizes and densities in different regions of the substrate. This local variation in hole characteristics allows optimization of liquid supply in different areas, preventing localized dry heating while maintaining overall control precision. The varied structure also reduces soot accumulation in specific high-risk areas.
2Productivity
If heating temperature is increased to improve atomization efficiency, then atomization amount increases, but tobacco soot generation increases, causing hole blockage and local dry heating
Solution Approach 1:
By segmenting the heating area into multiple zones corresponding to different pass-through holes, the invention allows distributed heat application. This reduces the temperature concentration in any single location, decreasing soot generation while maintaining overall atomization efficiency through coordinated heating of multiple zones.
Solution Approach 2:
The pass-through holes act as intermediaries between the liquid storage and atomization surfaces. They regulate liquid flow to ensure optimal liquid-film formation on the heating surface, preventing both dry heating (which generates soot) and excessive liquid supply (which reduces efficiency). This intermediary control mechanism balances atomization efficiency with soot reduction.
3Quantity of substance
If submicron holes are used to increase porosity, then liquid supply increases, but aroma transmission efficiency decreases due to absorption of flavor components
Solution Approach 1:
The invention employs different hole sizes in different regions: larger pores in areas requiring high liquid supply and smaller pores in areas where aroma preservation is critical. This spatial variation in pore size allows the system to achieve adequate liquid supply while minimizing the absorption of flavor components, thereby maintaining aroma transmission efficiency.
Solution Approach 2:
The invention changes the pore size parameter from uniform submicron dimensions to a distributed range of sizes. This parameter variation allows optimization of both liquid supply (through larger pores) and aroma transmission (through smaller pores in strategic locations), resolving the contradiction between quantity of liquid and quality of aroma.
