Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual water quality inspection is performed, then water quality can be checked, but it takes time and cannot continuously monitor water quality
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated analysis device that uses optical or electrochemical sensors to measure water quality parameters continuously. The control device automatically reads sensor data and controls valves based on predetermined references, eliminating manual intervention and enabling continuous monitoring without time loss.
Solution Approach 2:
The system performs self-monitoring and self-regulation through the control device that automatically interprets analysis results and controls the first valve based on predetermined quality references. The system serves itself by detecting water quality changes and adjusting supply without external manual intervention, enabling continuous operation.
2Measurement precision
If manual water quality inspection is performed, then water quality can be checked, but rapid changes in water quality cannot be detected promptly
Solution Approach 1:
The analysis device continuously monitors water quality parameters without interruption as water flows through the second pipe. The control device receives continuous data streams and immediately compares them against predetermined references, enabling real-time detection of rapid quality changes such as silica increases without the delays inherent in manual periodic sampling.
Solution Approach 2:
The patent replaces slow manual sampling and testing with automated continuous sensing technology that provides immediate detection of water quality changes. The optical or electrochemical sensors detect parameter changes instantaneously, and the control device responds immediately, achieving both high detection accuracy and rapid response speed.
3Productivity
If the first valve is opened to supply pure water, then water can be supplied to the storage tank, but water quality may deteriorate if not monitored
Solution Approach 1:
The control device receives continuous feedback from the analysis device about water quality parameters and automatically adjusts the first valve accordingly. When water quality meets predetermined references, the valve remains open to maintain supply efficiency. When quality deteriorates, the valve closes automatically to prevent poor quality water from reaching the storage tank, thus maintaining both productivity and reliability.
Solution Approach 2:
The system automatically monitors and regulates its own water supply based on real-time quality analysis. The control device independently compares analysis results against predetermined references and controls the first valve without external intervention, ensuring that only quality-compliant water is supplied while maintaining efficient operation.

Function Achieved in This Case
This system enables automated water quality management, ensuring continuous monitoring and prompt detection of changes in water quality, thereby maintaining the quality of pure water and optimizing the regeneration or exchange of ion exchange resin.
Implementation Method 1
the pure water is manufactured by sending water, from which impurities or organic substances are removed by making the water to pass through a sand filtration tower and an activated carbon tower, to an ion exchange resin device and by removing sodium, chloride, silica, or the like in the water using the ion exchange resin device
Implementation Method 2
a silica concentration meter that measures a silica concentration of the pure water

AI summary
The pure water manufacturing management system includes a pure water manufacturing device; an analysis device that inspects water quality; a first valve provided to first piping connected to the outlet side of the manufacturing device, the first valve controlling the amount of pure water supplied to a storage tank; second piping that branches from the first piping and is connected to the analysis device; and a control device, the control device controlling the analysis device during supply of the pure water to the storage tank, repeatedly performing water quality inspection of the pure water flowing in through the second piping, opening the first valve when, as a result of the water quality inspection, the water quality of the pure water satisfies a prescribed standard, and closing the first valve when the water quality of the pure water does not satisfy the prescribed standard.
