Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic atomizers experience slow start speed and unstable smoke production due to low voltage output from the booster circuit, leading to poor user experience and potential dry burning, especially after long intervals of non-use.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the voltage output by the booster circuit is kept small and constant, then the ultrasonic atomizer will not be dry-burnt or its life will not be shortened, but the start speed of the ultrasonic atomizer is slow and the amount of smoke is unstable
Solution Approach 1:
The patent applies dynamics by making the voltage output of the booster circuit adjustable rather than fixed. The voltage regulator circuit dynamically changes the voltage based on the working state: high voltage for startup to achieve fast start speed, and low voltage during normal operation to prevent dry burning and extend lifespan. This resolves the contradiction between reliability and speed by adapting the voltage to different operational phases.
Solution Approach 2:
The patent changes the voltage parameter dynamically based on the time interval between smoking switch activations. When the interval exceeds a preset threshold, the voltage regulator circuit increases the voltage to ensure fast startup and sufficient smoke production. When the interval is within the threshold, the voltage is maintained at a lower level to prevent overheating and extend atomizer life. This parameter adjustment resolves the contradiction between startup performance and operational reliability.
2Use of energy by moving object
If the voltage output by the booster circuit is kept small and constant, then energy consumption is reduced, but the amount of smoke is little during the first few puffs and the user experience is poor
Solution Approach 1:
The patent implements periodic action by detecting the time interval between smoking switch activations and adjusting the voltage accordingly. After a long interval (indicating the atomizer has been idle), the system applies high voltage for several cycles to quickly restore smoke production. After short intervals (normal continuous use), the system maintains lower voltage for energy efficiency. This periodic adjustment based on usage patterns resolves the contradiction between energy consumption and user experience.
3Speed
If the voltage output by the booster circuit is increased to improve startup speed, then the start speed of the ultrasonic atomizer is fast, but the ultrasonic atomizer will be dry-burnt or its life will be shortened due to excessive working voltage
Solution Approach 1:
The patent applies preliminary action by detecting whether the time interval between smoking switch activations exceeds a preset threshold before adjusting the voltage. When a long interval is detected, the system preliminarily determines that high voltage is needed for startup. When a short interval is detected, the system preliminarily determines that low voltage is sufficient. This preliminary assessment based on time interval prevents excessive voltage application and resolves the contradiction between startup speed and atomizer lifespan.
