Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling water is used to cool processing water in the temperature controller, then the processing water can be maintained at a fixed temperature for accurate cutting, but the cooling water temperature rises above the permissible drainage limit
Solution Approach 1:
The drainage path is segmented into multiple routes: a first drainage route for cooling water that has been heated by cooling the processing water, and a second drainage route for cooling water that has not been heated. This segmentation allows selective drainage of cooling water based on its temperature state, resolving the contradiction between maintaining processing water temperature and managing cooling water drainage temperature.
Solution Approach 2:
A temperature detection device acts as an intermediary between the cooling water system and drainage system. It detects the temperature of cooling water and provides information to the control device, which then determines the appropriate drainage route. This intermediary mechanism enables intelligent routing of cooling water based on temperature conditions.
2Reliability
If cooling water is drained directly when it exceeds the upper temperature limit, then drainage equipment is protected from overheating, but the cooling function for processing water becomes ineffective
Solution Approach 1:
The drainage system dynamically switches between different drainage routes based on real-time temperature conditions of the cooling water. The control device adjusts the drainage path in response to temperature changes, allowing the system to adapt to varying thermal states and maintain both cooling effectiveness and drainage safety.
Solution Approach 2:
The system changes the drainage route parameter based on the temperature parameter of the cooling water. When cooling water temperature is below the upper limit, it is routed through the first drainage route; when it exceeds the limit, the system switches to the second drainage route, thereby maintaining system reliability under different thermal conditions.

AI summary
A processing water supply system for supplying processing water to a processing apparatus includes a first heat exchanger that cools the processing water by heat of vaporization of a cooling medium, a second heat exchanger that cools the cooling medium compressed to reach a high temperature, a cooling water receiving route that receives the cooling water from cooling water supply equipment to the second heat exchanger, a cooling water drain route that drains the cooling water heat-exchanged by the second heat exchanger to reach a high temperature to drain equipment, and a bypass route that is disposed between the cooling water receiving route and the cooling water drain route and adjusts the cooling water reaching the high temperature at the second heat exchanger to a temperature permissible by the drain equipment.
