Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the induction coil is wound on an outer wall forming a cavity component, then the coil has a larger spiral inner diameter, but the generated magnetic field is less concentrated
Solution Approach 1:
The induction coil is extracted from the cavity component and mounted on the extractor instead, allowing the coil to have a smaller inner diameter and generate more concentrated magnetic fields while maintaining functional separation between heating and structural components
2Volume of moving object
If the induction coil is mounted on the extractor, then the magnetic field is more concentrated, but the power supply connection becomes more complex
Solution Approach 1:
The conductive element is nested within the extractor structure, with the induction coil wound around the extractor and the conductive element positioned to electrically connect the coil to the power supply through the extractor walls, integrating multiple functions into a compact nested arrangement
Solution Approach 2:
The conductive element acts as an intermediary between the induction coil and the power supply, penetrating through the extractor walls to establish electrical connection without requiring external wiring, thereby simplifying the overall power supply connection
3Ease of operation
If the extractor is designed for easy removal, then user convenience is improved, but the electrical connection stability may be compromised
Solution Approach 1:
The device is segmented into removable extractor and stationary cavity components, with the electrical connection system designed to maintain stable contact during insertion and removal operations through conductive elements that engage with electrical contacts in the cavity

AI summary
This application provides a vapor generation device, configured to heat a vapor generation article to generate an aerosol for inhalation, including: a cavity, configured to receive a vapor generation article; a susceptor, configured to be penetrated by a changing magnetic field and generate heat, to heat the vapor generation article received in the cavity; an extractor, at least partially received in the cavity and configured to extract the vapor generation article vapor generation article through movement in an axial direction of the cavity or removal from the cavity; an induction coil, configured to generate the changing magnetic field and held on the extractor; and a first electrical contact, configured to conduct with the induction coil when the extractor is received in the cavity, to supply power to the induction coil. Because the induction coil is formed on the extractor by the vapor generation device, the induction coil has a smaller spiral inner diameter than that wound on an outer wall forming a cavity component, so that the generated magnetic field may be more concentrated.
