Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-temperature heat is generated to quickly heat the object, then heating speed is improved, but heat loss to the outside increases and energy efficiency deteriorates
Solution Approach 1:
The patent creates a vacuum environment (inert atmosphere with removed gas molecules) within the heat transfer pipe to eliminate convective and conductive heat loss to the surroundings. By removing air and other gases from the internal space, heat generated by the heater is retained and efficiently transferred to the object, resolving the contradiction between rapid heating and energy loss
Solution Approach 2:
The patent employs a sealed pipe structure with a cover that creates a closed internal environment. This shell-like structure maintains the vacuum state and prevents heat escape, allowing high-temperature heating while minimizing energy loss to the external environment
2Stability of the object's composition
If heat is discharged to the outside to maintain stability, then temperature control is improved, but energy efficiency deteriorates
Solution Approach 1:
The vacuum environment prevents convective heat transfer and reduces radiative heat loss, allowing the system to maintain stable temperatures without continuous heat discharge. The inert atmosphere isolates the heated object from environmental factors that would otherwise require active temperature management through heat release
Solution Approach 2:
The patent changes the physical parameter of the internal environment from atmospheric pressure to vacuum state. This parameter change fundamentally alters heat transfer mechanisms, reducing energy loss while maintaining temperature stability through the inherent thermal isolation properties of the vacuum environment

AI summary
A method of manufacturing a heater module for an aerosol-generating device includes: preparing a heat transfer pipe having a hollow shape and including a thermal conductive material; forming an assembly of the heat transfer pipe and a cover by insert molding in which heat transfer pipe is placed in a mold and resin is injected into the mold, such that one end of the cover is integrally coupled to an end of the heat transfer pipe while a side wall of the cover is spaced apart from the heat transfer pipe and surrounds the heat transfer pipe; arranging a heater on an outer surface of the heat transfer pipe; and sealing, with a sealing stopper, a space between the heat transfer pipe and the cover such that internal pressure of the space is lower than atmospheric pressure.
