Solution Overview
Problem
Existing humidifiers face issues such as frequent maintenance of humidifying media in natural evaporation, inefficient sterilization and humidification in ultrasonic vibration methods, and safety concerns with direct discharge of hot humidified air in heating evaporation, particularly due to the interconnected water heating and humidifying spaces which hinder complete sterilization and reliable operation of ultrasonic vibrators.
Innovation Solution
A humidifier design featuring a dual-chamber structure with a first chamber for heating water and a second chamber for generating humidified air using heated water, where air flow is managed to cool the water before it reaches the second chamber, incorporating a fan to form air flows and guide air to the lower portion of the second chamber, and a temperature sensor to prevent high-temperature operation of the ultrasonic vibrator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water heating temperature is maintained below a set temperature to protect the ultrasonic vibrator, then the vibrator reliability is improved, but the water sterilization effectiveness deteriorates
Solution Approach 1:
The water tank is divided into two separate chambers: a first water tank for heating water to high temperatures for sterilization, and a second water tank for housing the ultrasonic vibrator at lower temperatures. This segmentation allows each chamber to operate at its optimal temperature without compromising the other, thus achieving both effective sterilization and vibrator protection.
Solution Approach 2:
The ultrasonic vibrator is extracted from the high-temperature heating environment and placed in a separate low-temperature chamber. This extraction removes the vibrator from the harmful high-temperature zone, allowing the heating chamber to reach temperatures sufficient for complete water sterilization while the vibrator operates in a safe temperature range.
2Object-affected harmful factors
If water is heated to sterilize and sent to the ultrasonic vibrator, then the water sterilization is improved, but the ultrasonic vibrator may malfunction due to high temperature
Solution Approach 1:
The system is segmented into a heating chamber for sterilization and a humidification chamber for vibrator operation. Water is heated in the first chamber, then transferred to the second chamber where the vibrator operates. This spatial segmentation ensures that the vibrator never directly contacts high-temperature water, preventing malfunction while maintaining sterilization effectiveness.
Solution Approach 2:
A temperature control mechanism acts as an intermediary between the heating process and the vibrator. The system heats water to sterilization temperatures, then allows it to cool to a safe temperature before introducing it to the ultrasonic vibrator chamber. This intermediary cooling step ensures both sterilization and vibrator protection.
3Productivity
If hot humidified air is discharged directly from the heating chamber, then the humidification efficiency is improved, but safety accidents may occur
Solution Approach 1:
The discharge system is segmented into separate outlets: one for hot sterilized air from the heating chamber and another for cool humidified air from the vibrator chamber. This segmentation allows the system to discharge both air streams independently, enabling efficient humidification while providing a safe cool outlet that prevents burn hazards.
Solution Approach 2:
The cool humidified air is extracted from the heating chamber and discharged separately through a dedicated outlet. This extraction of cool air from the hot environment allows the system to maintain high humidification efficiency while providing a safe discharge that does not pose burn risks to users.
4Device complexity
If a single chamber is used for both heating and humidifying, then the device complexity is reduced, but the water cannot be completely sterilized while protecting the vibrator
Solution Approach 1:
The single chamber is divided into two separate chambers: a first chamber for heating water to sterilization temperatures and a second chamber for housing the ultrasonic vibrator. This segmentation resolves the contradiction by allowing each chamber to perform its specific function at the appropriate temperature, achieving complete sterilization and vibrator protection while maintaining relatively simple overall device structure.
