Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a spray-type sterilization apparatus is mounted in a vehicle or handcart to sterilize wide spaces, then the sterilization coverage area is improved, but the mobility and freedom of movement are worsened
Solution Approach 1:
The sterilization apparatus is divided into separate functional modules: a chemical liquid supply device (storage tank and pump) and a sterilization device (atomization blower unit with nozzles), connected by a supply line. This segmentation allows the system to be configured for wide-area sterilization while maintaining portability and freedom of movement, as each module can be independently optimized and the connection allows flexible positioning.
2Quantity of substance
If a spray apparatus sprays a large amount of sterilizer to disinfect wide spaces, then the sterilization effectiveness is improved, but the droplet size increases causing sterilization efficiency to worsen
Solution Approach 1:
The atomization blower unit utilizes mechanical vibration or high-speed rotation of the nozzle assembly to atomize the chemical liquid into fine, uniform droplets. This allows a large quantity of sterilizer to be sprayed while maintaining consistent droplet size, ensuring both wide coverage and effective sterilization without the droplets becoming too large to be effective.
Solution Approach 2:
The system employs pneumatic atomization where compressed air or gas is used to break up the chemical liquid stream into fine droplets at the nozzle. This hydraulic/pneumatic mechanism enables precise control over droplet size while delivering a large volume of sterilizer, resolving the contradiction between spray quantity and droplet uniformity.
3Device complexity
If a spray pipe is installed in a straight linear direction for sterilization, then the structural simplicity is improved, but the spraying directionality is worsened
Solution Approach 1:
The spray apparatus incorporates a rotatable or adjustable nozzle assembly that can dynamically change the spraying direction. Instead of a fixed straight linear pipe, the atomization blower unit allows the spray direction to be adjusted or rotated, providing versatility in covering different areas while maintaining relatively simple overall structure through modular design.
