Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent start-and-stop operation of reverse osmosis (RO) water production in reagent preparation systems reduces efficiency and can lead to equipment breakdowns, as the system requires time to resume production after reaching predetermined water levels, disrupting the continuous reagent preparation process.
Innovation Solution
A reagent preparation apparatus and method that includes a controller to continuously produce purified water for a predetermined time after starting production, ensuring a stable supply of RO water and minimizing frequent stoppages, thereby enhancing production efficiency and extending equipment lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the RO water production is stopped when the predetermined amount is reached, then the reagent can be prepared in a short time, but the production efficiency lowers and equipment may break down due to frequent start-stop operations
Solution Approach 1:
The controller determines in advance whether to stop or continue RO water production by checking if the water level is between the first and second predetermined levels. This preliminary assessment prevents unnecessary stop operations, allowing the system to maintain continuous production when appropriate while still enabling quick reagent preparation when needed.
Solution Approach 2:
The system uses water level detection to provide feedback to the controller, which then adjusts production operations accordingly. When the water level is between the first and second predetermined levels, the controller receives feedback to continue production rather than stop, optimizing both efficiency and equipment reliability.
2Stability of the object's composition
If the RO water production is stopped frequently to maintain water level, then the water level is maintained, but the equipment preparation time increases and reliability decreases
Solution Approach 1:
The system establishes predetermined water levels (first and second levels) in advance to guide production decisions. By checking whether the current water level falls between these predetermined thresholds, the system can proactively determine whether to continue or stop production, preventing unstable water level fluctuations and reducing unnecessary equipment cycling.
Solution Approach 2:
The system introduces a second predetermined water level parameter to create a threshold range for continuous production. This parameter change transforms the binary stop/continue decision into a more nuanced control strategy where production continues when the level is within the optimal range, improving both stability and reliability.
3Productivity
If the RO water production continues until a predetermined time has elapsed, then frequent start-stop cycles are reduced, but excess water may be produced
Solution Approach 1:
The controller performs preliminary determination of whether to stop production by checking if the water level exceeds the second predetermined level before time elapses. This advance decision-making prevents unnecessary continuous operation and water waste while maintaining production efficiency when appropriate.
Solution Approach 2:
The system continuously monitors water level and provides feedback to the controller. When the level reaches the second predetermined level, the feedback triggers a production stop decision, preventing excess water production while allowing efficient continuous operation when levels remain within the optimal range.
