Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If aerosol-generation products are packaged in a pack for consumption, then storage and portability are improved, but moisture absorption occurs after opening leading to reduced heating effectiveness
Solution Approach 1:
The control unit performs preliminary detection of liquid content in the aerosol-generation product before heating. By measuring electrical parameters (capacitance, resistance, or impedance) of the product, the system determines the liquid content level in advance and adjusts the heating curve accordingly, preventing the negative effects of moisture absorption before they occur.
Solution Approach 2:
The system changes heating parameters (temperature, time, power) based on the detected liquid content. When high liquid content is detected due to moisture absorption, the control unit adjusts the heating curve to compensate, thereby maintaining heating effectiveness despite the changed product state.
2Ease of operation
If aerosol-generation products are stored after opening, then convenience is improved, but water content increases causing damping and reducing vaporization volume
Solution Approach 1:
The control unit continuously monitors the electrical parameters of the aerosol-generation product and uses this feedback to adjust the heating process. The system detects changes in liquid content over time and modifies heating parameters in real-time to maintain optimal vaporization performance.
Solution Approach 2:
The heating curve is made dynamic rather than fixed. The control unit adjusts heating parameters based on the current state of the product, allowing the system to adapt to changing liquid content conditions and maintain effective vaporization throughout the storage period.
3Reliability
If heating is applied to compensate for moisture, then vaporization effectiveness is improved, but energy consumption increases
Solution Approach 1:
The system applies heating in a controlled and partial manner based on actual needs. Rather than using a fixed high-power heating mode, the control unit adjusts the heating intensity and duration to match the detected liquid content level, applying only the necessary energy to achieve effective vaporization.
