Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-path drive circuit is used to control the ultrasonic atomization sheet, then the circuit structure is simple, but the atomization sheet can only oscillate at half wave with low efficiency and severe heat generation
Solution Approach 1:
The drive circuit is segmented into two independent drive oscillation circuits, each controlling one end of the ultrasonic atomization sheet. This segmentation allows both ends to oscillate simultaneously in opposite phases, transforming half-wave oscillation into full-wave oscillation and significantly improving atomization efficiency while reducing heat generation.
2Adaptability or versatility
If multiple lithium battery packs are used to provide different operating voltages, then the voltage requirements are met, but the cost is high and the size is large
Solution Approach 1:
A single lithium battery pack is designed to provide multiple voltage levels (3.7V for control circuit, 5V for drive circuits, and 16V for oscillation circuits) through voltage division and boosting circuits. This multi-functional power supply design eliminates the need for multiple separate battery packs, reducing overall size, weight, and cost while meeting all voltage requirements.
3Weight of stationary object
If a single lithium battery is used with voltage division and boosting circuits, then the size and cost are reduced, but the voltage conversion complexity increases
Solution Approach 1:
Multiple voltage conversion functions (voltage division, voltage boosting, and voltage regulation) are merged into a single integrated power management system. The voltage division circuit provides 3.7V and 5V, while the boosting circuit converts these to the required 16V for the oscillation circuits. This unified approach consolidates what could be separate complex circuits into a coordinated system that reduces overall complexity.
