Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electromagnetic waves are irradiated onto an aerosol-generating article, then aerosol generation is enabled, but suitable irradiation cannot be achieved depending on device configuration
Solution Approach 1:
The patent employs a loop antenna that can rotate around the aerosol-generating article, dynamically adjusting the irradiation position and angle. This dynamic configuration allows the system to adapt to different article shapes and sizes, ensuring reliable electromagnetic wave irradiation regardless of device configuration variations.
Solution Approach 2:
The control unit adjusts irradiation parameters including frequency, power level, and antenna position based on detected article characteristics. By changing these parameters dynamically, the system achieves suitable irradiation effectiveness across different device configurations and article types.
2Area of stationary object
If a loop antenna is used to supply electromagnetic waves, then irradiation coverage is improved, but device complexity increases
Solution Approach 1:
The loop antenna serves multiple functions: it generates electromagnetic waves, detects article presence and characteristics, and provides feedback for control. This multi-functionality reduces the need for separate components, thereby managing device complexity while maintaining broad irradiation coverage.
Solution Approach 2:
The system incorporates feedback mechanisms where the loop antenna detects article characteristics and the control unit adjusts irradiation parameters accordingly. This closed-loop control simplifies the overall system by using the antenna's dual role in transmission and detection to automatically optimize performance.
