Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If electric heating technology is used for humidification, then humidification efficiency is improved, but power consumption increases and safety deteriorates
Solution Approach 1:
The patent replaces electric heating (thermal field) with ultrasonic vibration (mechanical field) to achieve humidification. The ultrasonic vibration module generates high-frequency vibrations that directly atomize water molecules, eliminating the need for heating elements and reducing power consumption while maintaining safety.
Solution Approach 2:
The patent utilizes the phase transition of water from liquid to aerosol droplets through ultrasonic vibration. The high-frequency mechanical vibration causes water to break into fine droplets that evaporate and humidify the air, achieving efficient humidification without thermal energy conversion.
2Use of energy by moving object
If ultrasonic technology is used for humidification, then power consumption is reduced, but health effects deteriorate
Solution Approach 1:
The patent incorporates a porous water absorption filter element that allows water to pass through while being atomized by ultrasonic vibration. The porous structure ensures complete water absorption and prevents white powder pollution, while the filtered water vapor is healthier for human respiration compared to traditional ultrasonic humidification.
Solution Approach 2:
The patent combines ultrasonic vibration technology with porous water absorption filter materials to create a composite humidification system. This integration maintains the energy efficiency of ultrasonic technology while eliminating its harmful effects through the filtering and absorption properties of the porous materials.
3Productivity
If wet film humidifying technology is used, then humidification effect is improved, but bacterial and mold growth increases
Solution Approach 1:
The patent extracts the water from a stagnant wet film reservoir and delivers it directly to the ultrasonic vibration module for immediate atomization. This eliminates the wet film environment that supports bacterial and mold growth, while maintaining effective humidification through direct water-to-aerosol conversion.
Solution Approach 2:
The patent employs a water pump that automatically draws water from the reservoir and supplies it to the ultrasonic vibration module. This self-service water delivery system ensures continuous fresh water supply for atomization, preventing the stagnation and contamination associated with traditional wet film systems.
4Ease of manufacture
If traditional humidification structures are used, then manufacturing is simplified, but cleaning difficulty increases and white-powder pollution occurs
Solution Approach 1:
The patent divides the humidification system into distinct functional modules: water reservoir, water pump, porous water absorption filter element, ultrasonic vibration module, and air outlet. This segmentation allows each component to be independently manufactured and easily removed for cleaning, eliminating the structural complexity while improving maintainability and preventing white powder accumulation.
