Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water is heated using a heater in a combination type humidification device, then the vaporization degree is improved, but a large amount of energy is consumed
Solution Approach 1:
The patent combines the ultrasonic vibration function and heater function into a single humidification device. The ultrasonic vibrator generates fine water particles while the heater simultaneously heats these particles, merging two functions (ultrasonic atomization and thermal vaporization) into one integrated system to achieve both fine particle generation and effective vaporization without requiring separate devices
Solution Approach 2:
The patent controls the temperature parameter by heating water to a specific range (50-80 degrees Celsius) rather than boiling point, and controls particle size through ultrasonic vibration frequency. This parameter optimization allows effective vaporization at lower temperatures, reducing energy consumption while maintaining high vaporization degree
2Ease of operation
If an ultrasonic humidification device discharges fine water particles, then the peripheral portion is smoothly humidified, but the humidification degree is significantly reduced as distance increases
Solution Approach 1:
The patent changes the physical state parameter of water particles by heating them to 50-80 degrees Celsius, transforming them from cold fine particles to warm vaporized particles. This parameter change increases the particles' buoyancy and dispersal capability, allowing them to travel farther distances while maintaining smooth humidification in peripheral areas
Solution Approach 2:
The patent introduces heated air as an intermediary medium that carries the fine water particles generated by the ultrasonic vibrator. The heated air current acts as a transport medium, propelling the vaporized water particles farther into the surrounding environment, thereby extending the effective humidification distance
3Device complexity
If an ultrasonic humidification device directly discharges fine water particles, then the device structure is simple, but a white dust phenomenon occurs
Solution Approach 1:
The patent changes the temperature parameter of water particles from ambient temperature to heated temperature (50-80 degrees Celsius). This parameter change causes the water particles to vaporize rather than remain as liquid droplets, eliminating the white dust phenomenon while maintaining the simple device structure of direct discharge
Solution Approach 2:
The patent converts the potentially harmful fine water particles that cause white dust into beneficial vaporized water molecules through heating. The same ultrasonic-generated fine particles that would normally cause white dust are instead transformed into invisible vapor that provides effective humidification without the harmful side effect

AI summary
A humidification module includes a housing including a lower part to store water and a guide part to guide droplets generated from the stored water to an upper part of the housing, and a fan configured to guide heated air to the housing. The housing includes a first flow path through which a first part of the heated air guided by the fan passes through the lower part of the housing and is guided with the droplets to the upper part of the housing by the guide part, and a second flow path through which a second part of the heated air guided by the fan that vaporizes the droplets guided with the first part of the heated air passes and is guided to the upper part of the housing by the guide part.
