Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If contact heating is used with contact points to heat the heating wire, then the heating function can be achieved, but the assembly becomes complex and liquid leakage risk increases
Solution Approach 1:
The patent removes the contact points and external circuit connections from the atomization body, extracting the problematic elements that caused assembly complexity and liquid leakage risks. The heating function is achieved through electromagnetic induction without physical contact points, eliminating the sources of reliability issues while maintaining the heating capability.
Solution Approach 2:
The patent replaces the mechanical contact-based heating system with an electromagnetic induction system. Instead of using contact points to conduct electricity to a heating wire, the system uses a coil to generate an alternating magnetic field that induces eddy currents in a metal heating sheet, achieving heating without mechanical contact and thus eliminating assembly complexity and liquid leakage risks.
2Loss of energy
If contact points are used to connect the heating wire to the circuit, then electrical connection is achieved, but heating efficiency decreases due to contact point resistance
Solution Approach 1:
The patent replaces the electrical contact system with an electromagnetic field-based energy transfer system. The coil generates an alternating magnetic field that directly induces eddy currents in the heating sheet without requiring physical electrical contacts, eliminating contact resistance and associated energy losses, thereby improving heating efficiency.
Solution Approach 2:
The patent introduces an alternating magnetic field as an intermediary to transfer energy from the power source to the heating element. Instead of direct electrical contact, the magnetic field serves as the medium for energy transfer, avoiding the resistance problems associated with physical contact points while maintaining efficient energy delivery to the heating sheet.
3Loss of energy
If electromagnetic induction is used to heat a small-size heating member, then non-contact heating is achieved, but heating efficiency becomes low
Solution Approach 1:
The patent concentrates the electromagnetic energy into a localized region by using a coil with specific geometry and positioning the heating sheet precisely within the magnetic field. This creates a high energy density zone that efficiently heats the small-size heating member, overcoming the general inefficiency of electromagnetic induction for small components.
Solution Approach 2:
The patent optimizes the spatial arrangement of the coil and heating sheet to maximize coupling efficiency. By carefully designing the three-dimensional configuration and positioning, the system achieves effective energy transfer to the small heating member, resolving the limitation of low heating efficiency for compact components.
