Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In low humidity environments like aircraft, electrostatic atomizing devices require a certain level of humidity to generate ions, but the air is typically too dry, and existing methods to humidify, such as using a fan, do not effectively prevent dew condensation, which can lead to equipment failure.
Innovation Solution
A humidifying device with a thermometer, hygrometer, cooler, and cooling control unit that adjusts cooling intensity to maintain a specific humidity level, preventing dew condensation while ensuring the electrostatic atomizing device can operate effectively without a water tank, thus avoiding corrosion and fatigue issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fan is used to humidify the air, then the air circulation is improved, but dew condensation occurs leading to equipment failure
Solution Approach 1:
The invention changes the temperature parameter of the air by using a cooler to lower the air temperature before it reaches the electrostatic atomizing device. This temperature reduction increases the relative humidity of the air without adding water, thereby preventing dew condensation while maintaining equipment reliability. The cooling control unit adjusts the cooling intensity based on detected temperature and humidity values to optimize this parameter change.
Solution Approach 2:
The invention replaces the mechanical humidification method (using a fan to circulate air) with a thermal field-based method (using a cooler to reduce temperature and increase relative humidity). This substitution eliminates the harmful effect of dew condensation while achieving the desired humidification effect for the electrostatic atomizing device.
2Reliability
If the humidity is increased to enable ion generation, then the electrostatic atomizing device can operate, but dew condensation may occur causing equipment failure
Solution Approach 1:
The invention changes the temperature parameter rather than adding moisture to increase humidity. By lowering the air temperature with the cooler, the relative humidity increases to enable ion generation in the electrostatic atomizing device, while the controlled cooling prevents dew condensation. The cooling control unit monitors temperature and humidity parameters to maintain optimal conditions.
Solution Approach 2:
The cooler acts as an intermediary device between the air intake and the electrostatic atomizing device. It modifies the air parameters (temperature and relative humidity) to create suitable conditions for ion generation while preventing harmful dew condensation, thus mediating between the conflicting requirements of humidity increase and dew condensation prevention.
3Quantity of substance
If a water tank is used for humidification, then the humidity level is increased, but the device complexity and corrosion risk increase
Solution Approach 1:
The invention extracts the water tank component from the humidification system entirely. Instead of using a water tank to add moisture to the air, the system uses a cooler to reduce air temperature and increase relative humidity. This extraction simplifies the device structure, eliminates corrosion risks associated with water storage, and maintains the necessary humidity level for electrostatic atomization.
Solution Approach 2:
The invention replaces the water-based humidification system (water tank) with a thermal-based system (cooler). This substitution eliminates the need for water storage components, reducing device complexity and removing the source of corrosion while achieving the same functional outcome of maintaining adequate humidity for ion generation.

AI summary
A humidifying device includes an air inlet, an internal air passage through which air taken in from the air inlet passes, a first thermometer that measures a temperature of the air taken in from the air inlet, a first hygrometer that measures a humidity of the air taken in from the air inlet, a cooler installed in a path of the internal air passage, and a cooling control unit that controls the cooler. The cooling control unit changes a cooling intensity of the cooler in a case where values measured by the first thermometer and the first hygrometer are out of a predetermined range.
