Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If an ultrasonic atomizer is used to atomize decontamination liquid, then the decontamination liquid can be generated, but the droplets tend to be large making it difficult to diffuse
Solution Approach 1:
The invention divides the atomization process into multiple stages using a multi-layer diaphragm structure. Each layer contains multiple through-holes that progressively break up the liquid into smaller droplets. The first diaphragm layer creates initial atomization, while the second diaphragm layer further subdivides the droplets, achieving much finer particle sizes that can diffuse effectively throughout the culture device interior.
Solution Approach 2:
The diaphragm layers are designed with specific local characteristics - the first diaphragm layer has through-holes with a first diameter, while the second diaphragm layer has through-holes with a second diameter that is smaller than the first. This local variation in hole size creates a progressive atomization effect, with each layer optimized for its specific function in the atomization sequence.
2Device complexity
If the diaphragm is disposed horizontally, then the structure is simple, but bubbles are retained making continuous atomization difficult
Solution Approach 1:
The invention introduces asymmetry in the diaphragm arrangement by tilting the diaphragm layers at a specific angle relative to the horizontal plane. This asymmetric positioning allows bubbles to naturally drain away from the through-holes under gravity, preventing bubble accumulation that would otherwise block the atomization process and ensure continuous operation.
Solution Approach 2:
The invention adds a dimensional aspect to the diaphragm positioning by arranging the diaphragm layers in an inclined configuration rather than purely horizontal. This three-dimensional arrangement creates a gradient that facilitates bubble movement and drainage, solving the bubble retention problem while maintaining structural feasibility.
3Device complexity
If a single diaphragm layer is used, then the device is simple, but droplet size is large and diffusion is poor
Solution Approach 1:
The invention divides the atomization process into multiple stages using a multi-layer diaphragm structure. Each layer contains multiple through-holes that progressively break up the liquid into smaller droplets. The first diaphragm layer creates initial atomization, while the second diaphragm layer further subdivides the droplets, achieving much finer particle sizes that can diffuse effectively throughout the culture device interior.
Solution Approach 2:
The invention employs a nested structure where the second diaphragm layer is positioned downstream of the first diaphragm layer in the liquid flow path. The atomization process is nested sequentially - the first layer performs initial breakdown, and the second layer performs further subdivision. This nested arrangement allows progressive refinement of droplet size without requiring a completely separate atomization system.
