Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a gas supply channel with gas supply holes is used to generate fine gas bubbles, then gas bubbles can be introduced into the liquid, but the density and refinement of gas bubbles are limited
Solution Approach 1:
The flow channel is divided into multiple sections with progressively smaller inner diameters (first choke portion, second choke portion, third choke portion), creating staged segmentation that progressively refines gas bubbles while increasing their density through controlled flow velocity increases at each stage
Solution Approach 2:
The inner diameter of the flow channel is dynamically changed along the flow direction, creating a tapered configuration that continuously accelerates liquid flow and progressively refines gas bubbles from larger to smaller sizes while increasing bubble density
2Manufacturing precision
If the flow velocity is increased to refine gas bubbles, then bubble size decreases, but the pump must handle higher flow rates which increases complexity
Solution Approach 1:
The pump unit is merged with the flow channel by disposing the pump within the flow channel structure, integrating pumping functionality with the flow path to avoid separate pumping components and reduce overall device complexity while achieving high flow velocities
Solution Approach 2:
The flow channel serves multiple functions: it guides liquid flow, acts as a choke portion to accelerate flow for bubble refinement, and houses the pump unit, thereby reducing the number of separate components needed and simplifying the overall device structure
