Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In constant temperature water supply systems, water temperature variations occur due to external factors when the constant temperature water supply apparatus and processing apparatus are installed at distant locations, leading to temperature changes of several degrees, making it difficult to maintain desired temperatures for processing and cooling water.
Innovation Solution
A system with a constant temperature water supply apparatus, a processing apparatus, and control means that includes a reservoir tank, delivery pump, water temperature adjusting means, and control units for detecting and adjusting water temperature differences, ensuring water is supplied at the desired temperature by resetting the predetermined temperature based on detected differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If water is supplied from a distant constant temperature water supply apparatus to the processing apparatus, then the water supply system can serve multiple locations, but the water temperature changes due to external factors during transmission
Solution Approach 1:
The system employs a feedback control mechanism where the actual water temperature detected at the processing apparatus is continuously monitored and compared with the target temperature. The control unit automatically adjusts the predetermined temperature of the water temperature adjusting means based on the detected temperature difference, ensuring that the water temperature remains stable despite external factors during transmission through distant pipes.
2Ease of operation
If the water temperature is adjusted to a predetermined temperature in the constant temperature water supply apparatus, then the water temperature can be controlled, but the temperature may not reach the desired temperature at the processing apparatus due to external factors
Solution Approach 1:
The control unit receives the actual water temperature from the water temperature detecting means and automatically adjusts the predetermined temperature setting of the water temperature adjusting means based on the detected temperature difference. This feedback mechanism ensures that the water temperature reaches the desired precision at the processing apparatus, compensating for temperature changes during transmission.
Solution Approach 2:
The system preliminarily adjusts the predetermined temperature of the water temperature adjusting means based on the detected temperature difference before water is supplied to the processing apparatus. By pre-adjusting the temperature compensation, the system ensures that the water temperature will be accurate when it reaches the processing apparatus, rather than waiting for temperature deviations to occur.
3Adaptability or versatility
If the water temperature changes during supply, then the water can adapt to environmental conditions, but the processing accuracy deteriorates and equipment damage may occur
Solution Approach 1:
The feedback control mechanism continuously monitors the water temperature at the processing apparatus and automatically adjusts the predetermined temperature of the water temperature adjusting means to compensate for environmental factors. This ensures that the water temperature remains stable and reliable for processing operations, preventing deterioration of processing accuracy and equipment damage.
Solution Approach 2:
The system applies preliminary anti-action by pre-adjusting the predetermined temperature to counteract the expected temperature changes caused by external factors during water transmission. This proactive temperature compensation prevents temperature deviations that would otherwise lead to processing accuracy deterioration and potential equipment damage.
