Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fixed power supply is used for the heater, then device structure is simple, but vaporization consistency is poor
Solution Approach 1:
The patent implements dynamic power adjustment by transitioning from a fixed power supply to a variable power control system. The controller modifies the power supplied to the heater in real-time based on detected operating conditions, enabling consistent vaporization across different operating points while maintaining manageable system complexity through automated control logic.
Solution Approach 2:
The patent employs feedback control by detecting operating parameters (such as temperature or power consumption) and using this information to adjust the heater power dynamically. The controller receives feedback about the current operating state and modifies the power supply accordingly to maintain optimal vaporization performance across varying conditions.
2Productivity
If multiple operating points are implemented, then vaporization efficiency is improved, but power control complexity increases
Solution Approach 1:
The patent segments the operating range into multiple discrete operating points, each optimized for specific vaporization efficiency requirements. The controller can select from these pre-defined operating points based on detected conditions, allowing efficient vaporization across different scenarios while managing complexity through structured power levels rather than continuous adjustment.
Solution Approach 2:
The patent utilizes parameter changes by varying the power level to different operating points based on detected conditions. The controller modifies electrical parameters (voltage, current, or power) to transition between predefined operating states, optimizing vaporization efficiency for different material types or usage conditions without requiring complex continuous control mechanisms.

AI summary
A method of controlling a heater of a device including a removable container that stores a material includes detecting, from the removable container, power information indicating a first operating point and a second operating point; and supplying power to the heater based on the detected power information by, determining a first amount of power based on the first operating point, supplying the first amount of power to the heater during a first operation mode of the heater, determining a second amount of power based on the second operating point, and supplying the second amount of power to the heater during a second operation mode of the heater, the second amount of power being higher than the first amount of power, the device being a non-nicotine e-vaping device or a heat-not-burn aerosol-generating device, the material being a non-nicotine pre-vapor formulation or an aerosol-forming substrate.
