Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a cylindrical part is used to remove bubbles from sample water, then large bubbles can be removed, but microbubbles cannot be removed and bubbles are not removed well when a large amount of water is supplied
Solution Approach 1:
The bubble removal function is divided into two distinct components: a cylindrical part for removing large bubbles and a mesh part for removing microbubbles. This segmentation allows each component to specialize in removing bubbles of different sizes, solving the problem where the cylindrical part alone could not remove microbubbles effectively.
Solution Approach 2:
Different parts of the bubble removal device have different structures optimized for different functions: the cylindrical part with its smooth surface is optimized for large bubble removal, while the mesh part with its fine openings is optimized for microbubble removal. This local differentiation of structure and function enables effective removal of all bubble sizes.
2Measurement precision
If sample water pressure varies due to external factors, then water quality measurement reliability deteriorates, but maintaining constant pressure requires additional control mechanisms
Solution Approach 1:
The constant pressure valve automatically adjusts the water flow to maintain constant pressure without requiring external control systems. The valve uses the water flow itself to regulate pressure, eliminating the need for complex external pressure control mechanisms while ensuring reliable water quality measurements.
3Measurement precision
If bubbles are present in sample water, then optical measurement of turbidity becomes inaccurate, but removing all bubbles requires complex processing
Solution Approach 1:
The bubble removal system is segmented into two simple components: a cylindrical part for large bubbles and a mesh part for microbubbles. This segmentation achieves comprehensive bubble removal without requiring complex processing systems, as each simple component targets a specific bubble size range.
Solution Approach 2:
A mesh part with porous structure is used to remove microbubbles from the water sample. The porous mesh allows water to pass through while trapping and removing microbubbles, providing an simple yet effective solution for microbubble removal without complex processing.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures consistent water supply to water quality meters at constant flow rate and pressure, effectively removing microbubbles to enhance measurement accuracy and reliability.
Implementation Method 1
when sample water flowing in the first pipe passes through the strainers, bubbles in the sample water stick to outer walls or inner walls of the strainers
Implementation Method 2
a constant pressure valve mounted at a first end of the first pipe such that sample water from the outside flows at constant flow rate and pressure into the first pipe
Implementation Method 3
a resistance valve mounted at a first end of the second pipe such that sample water flowing through the second pipe is discharged at constant flow rate and pressure out of the second pipe
