Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single heating mode is used in aerosol generating devices, then the device structure remains simple, but the adaptability and user flexibility are limited
Solution Approach 1:
The aerosol generating device incorporates both a heater and a vaporizer that can operate in different modes (smokeless mode with heater only, smoke mode with both heater and vaporizer) to provide multi-functional capability. This allows a single device to serve multiple purposes - generating both smokeless and smoke aerosols based on user needs, thereby improving adaptability without requiring completely separate devices
Solution Approach 2:
The device employs dynamic control through a controller that adjusts power supply to the heater and vaporizer based on the selected mode. The controller dynamically switches between different operating configurations: smokeless mode (heater only), smoke mode (both heater and vaporizer), and adjustable power ratios, enabling the system to adapt its behavior in real-time based on user requirements
2Adaptability or versatility
If power is supplied to both heater and vaporizer simultaneously, then smoke aerosol can be generated, but energy consumption increases
Solution Approach 1:
The controller dynamically adjusts power distribution between the heater and vaporizer based on the selected operating mode. In smokeless mode, only the heater receives power, conserving energy. In smoke mode, both heater and vaporizer receive power simultaneously. The system can also operate in intermediate states with adjustable power ratios, allowing users to optimize energy consumption based on their specific needs for each aerosol type
Solution Approach 2:
The device changes operational parameters by controlling the power supply levels to different heating elements based on the desired aerosol type. The controller adjusts electrical parameters (power, voltage, current) to the heater and vaporizer, enabling the system to transition between energy-efficient smokeless operation and smoke-generating operation with higher power consumption, providing flexible energy management
