Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a preset power profile is used for dielectric heating, then the heating operation can be performed with high power, but the power usage efficiency is reduced and heating control precision is insufficient
Solution Approach 1:
The patent implements a feedback mechanism where the controller monitors power consumption data during smoking sessions and uses this information to dynamically adjust and update the power profile. This closed-loop control ensures that high power is applied when needed for effective heating while optimizing energy usage by adapting to actual consumption patterns, thereby resolving the contradiction between maintaining high heating power and improving power usage efficiency.
Solution Approach 2:
The power profile is transformed from a static preset configuration to a dynamic, adaptive parameter that changes based on monitored power consumption data. The controller continuously updates the power profile during and between smoking sessions, allowing the heating power to be optimized in real-time according to actual usage conditions, thus achieving both high power performance and energy efficiency.
2Power
If a preset power profile is used for dielectric heating, then the heating operation can be performed, but the heating temperature control precision is reduced
Solution Approach 1:
The controller monitors power consumption data during smoking sessions and uses this feedback to precisely adjust the power profile. By analyzing actual power usage patterns and updating the power profile accordingly, the system achieves precise heating temperature control while maintaining the necessary high power levels for effective dielectric heating of the aerosol-generating article.
Solution Approach 2:
The patent dynamically changes the power profile parameters based on monitored power consumption data. The controller adjusts power levels, timing, and distribution in the power profile to achieve precise heating temperature control, transforming the power delivery characteristics to match actual heating requirements and thereby improving temperature control precision.
3Use of energy by moving object
If the power profile is updated based on monitored power feedback data, then the power usage efficiency is improved and heating control precision is enhanced, but the device complexity increases
Solution Approach 1:
The patent implements a feedback-based power profile update mechanism where the controller monitors power consumption data and automatically adjusts the power profile. This approach improves power usage efficiency and heating control precision through intelligent adaptation rather than complex hardware modifications. The feedback loop uses software-based optimization algorithms that enhance performance without significantly increasing physical device complexity.
Solution Approach 2:
The system performs self-optimization by automatically monitoring its own power consumption and updating its power profile without external intervention. The controller uses the monitored power feedback data to autonomously adjust heating parameters, eliminating the need for complex manual calibration systems or additional sophisticated control hardware, thereby improving efficiency while keeping device complexity manageable.
