Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the resistance of the heating wire is reduced or the driving voltage is increased to increase the atomization amount, then the atomization amount increases, but carbon deposits are generated on the heating wire surface and service life shortens
Solution Approach 1:
The single heating wire is divided into two separate heating wires (first heating wire and second heating wire). Each heating wire can be independently controlled and switched, allowing the system to segment the heating function to reduce carbon deposit accumulation on any single wire, thereby extending service life while maintaining atomization performance.
Solution Approach 2:
The control circuit board implements periodic switching between the first and second heating wires. By alternating the activation of each heating wire, the system distributes the thermal stress and carbon deposit formation across both wires over time, preventing excessive carbon accumulation on a single wire and extending the overall service life.
2Manufacturing precision
If the heating power of the heating wire is increased to improve atomization taste, then the atomization taste improves, but carbon deposits are generated more rapidly
Solution Approach 1:
The control circuit board periodically switches between the first and second heating wires, allowing each wire to operate at high power for improved atomization taste while having sufficient rest periods to cool down and reduce carbon deposit formation. This periodic alternation enables high-performance atomization without rapid carbon accumulation.
Solution Approach 2:
When one heating wire becomes heavily carbonized, the system switches to the other heating wire, effectively discarding the degraded wire and recovering the service life by utilizing the second wire. This allows the system to maintain good atomization taste while extending overall operational life.
3Device complexity
If a single heating wire is used, then the device structure is simple, but the e-liquid capacity is limited and service life is short
Solution Approach 1:
The heating system is segmented into two independent heating wires with separate control circuits. This segmentation allows the e-liquid reservoir to be effectively doubled in capacity utilization, as each heating wire can process e-liquid independently. The service life is extended because when one wire degrades, the other can continue operation.
Solution Approach 2:
The system merges two heating wire subsystems into a single integrated e-cigarette device. By combining the functionality of two heating wires with a shared control circuit board and power supply, the device achieves extended service life and increased e-liquid capacity while maintaining relatively simple overall structure.
