1. Functional Design
The functional design should be reasonable and in line with the user’s operating habits. Currently, the common one is 5-speed energy adjustment: click the mode switch button to select different parts for hair removal.
Mode Control
- Short press the function key to switch the mode when the machine is turned on.
- The key flashes automatically and continuously, indicating two hair removal modes.
2. Circuit Board Layout
The layout of the circuit board should be reasonable, to avoid mutual interference between strong and weak currents, and to ensure that the circuit board will not fail in the long-term use.
3. Software Optimization
Software optimization should be done well to ensure:
- The excitation gear is correct.
- There is no overheating or insufficient energy.
Charging the Capacitor
To charge the capacitor, it is necessary to control the current:
- If the current is too large, the service life of the device will be affected.
- If the current is too small, the charging will be too slow, affecting the user experience.
4. Aging Mode Design
The aging mode design should be reasonable to:
- Facilitate mass production testing of all functions.
- Ensure the quality of shipments.
