Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the aerosol generating device is miniaturized, then the device size is reduced, but the heating efficiency and heat dissipation are compromised
Solution Approach 1:
The patent transitions from a planar arrangement of components to a three-dimensional stacked configuration. The oscillating unit is positioned above the resonating unit with vertical spacing, utilizing the Z-axis dimension to achieve compact integration while preserving functional performance. This dimensional change allows the device to be miniaturized in the horizontal plane without compromising heating efficiency or heat dissipation capabilities.
2Volume of moving object
If the oscillating unit and resonating unit are arranged in a stacked configuration, then the device is miniaturized, but the component arrangement complexity increases
Solution Approach 1:
The patent merges the oscillating unit and resonating unit into a single integrated heater assembly structure. By stacking these units vertically and connecting them through a coupler, the design combines multiple functional components into a compact modular unit that reduces overall device size while managing arrangement complexity through systematic integration.
3Volume of moving object
If the oscillating unit is stacked on the resonating unit, then the device is miniaturized, but the microwave transmission efficiency may be affected
Solution Approach 1:
The patent introduces a coupler as an intermediary component between the oscillating unit and the resonating unit. This coupler serves as a mediator that facilitates efficient microwave energy transfer from the oscillating unit to the resonating unit, ensuring that the stacked configuration maintains high transmission efficiency despite the vertical arrangement and spacing between units.
