Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed sampling conditions are used in existing water sampling devices, then the device structure is simple, but the adaptability to varying water quality measurement needs deteriorates
Solution Approach 1:
The patent applies dynamics by making the sampling conditions changeable rather than fixed. The control means can adjust sampling amount, number of sampling containers, and container types based on water quality measurement results, transforming a static system into a dynamic one that adapts to varying measurement needs.
Solution Approach 2:
The patent implements parameter changes by allowing modification of key sampling parameters including sampling amount, number of sampling containers, and container types. These parameters can be adjusted based on the measured water quality, enabling the system to optimize sampling conditions for different measurement scenarios.
2Adaptability or versatility
If sampling conditions are made changeable to improve adaptability, then the adaptability to varying measurement needs is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a control means that handles multiple functions: determining sampling conditions, controlling the sampling operation, managing washing operations, and coordinating multiple sampling containers. This single control unit performs diverse tasks, reducing the need for separate specialized components for each function.
Solution Approach 2:
The system implements self-service through automatic control based on water quality measurements. The control means automatically determines appropriate sampling conditions and executes sampling operations without manual intervention, and can automatically perform washing operations, reducing the need for complex manual control mechanisms.
3Adaptability or versatility
If multiple sampling containers are used to increase sampling capacity, then the sampling flexibility is improved, but the device complexity and space requirements increase
Solution Approach 1:
The patent applies segmentation by dividing the sampling system into multiple independent sampling containers that can be selectively used. Each container can be independently controlled and managed, allowing the system to scale sampling capacity by adding or removing containers as needed, rather than requiring a single large complex container.
Solution Approach 2:
The system implements dynamics by making the number of sampling containers changeable based on measurement needs. The control means can determine whether to use one container or multiple containers for sampling, transforming a static container configuration into a dynamic one that adapts to the required sampling capacity.

AI summary
A water sampling device for water quality measurement is capable of changing the sampling amount, the number of sampling container(s), the sampling container type and so on according to the item of water quality measurement. Water in a water system can be sampled into a first container Y1 via a sampling source pipe 1, a manifold 2, and a first sampling pipe 3 and a pump P1 connected to the manifold 2. Water in the water system also can be sampled into a second container Y2 from the manifold 2 via a second sampling pipe 4 and a pump P2. In a case where the detection value(s) of one or more of the sensors S1 to S3 set in the water system exceeds a preset standard value or deviates from a standard range, water to be tested is sampled from the water system.
