Solution Overview
Problem
Existing apparatuses for sampling phosphoric acid are not capable of rapid sampling, leading to inefficient monitoring of production processes.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional filtering apparatus is used to take phosphoric acid samples, then the apparatus structure is simple, but the sampling speed is slow and cannot enable rapid monitoring
Solution Approach 1:
The apparatus is divided into two independent chambers (first chamber for storage, second chamber for sampling) that can operate independently. This segmentation allows the sampling chamber to be filled and emptied without affecting the storage chamber, enabling rapid sequential sampling operations while maintaining a relatively simple overall structure.
Solution Approach 2:
The apparatus incorporates dynamic control through closure members (valves) on the conduits that can be opened or closed to control sample flow. This dynamic control enables rapid switching between sampling operations and storage operations, significantly improving sampling speed while using simple valve mechanisms rather than complex systems.
2Productivity
If filtration is performed in the production tank, then the sampling process is integrated, but the monitoring efficiency is reduced due to slower sampling rate
Solution Approach 1:
The sampling and filtration operations are extracted from the production tank and performed in a separate second chamber. This extraction allows sampling to occur independently and rapidly without interrupting or slowing down the main production process, thereby improving monitoring efficiency while minimizing time loss through dedicated sampling infrastructure.
Solution Approach 2:
The first chamber continuously stores filtered phosphoric acid in advance, so when sampling is needed, the second chamber can be quickly filled from the first chamber without waiting for new filtration to complete. This preliminary storage action enables rapid sampling operations and improves monitoring productivity without time loss.
3Speed
If rapid sampling is implemented, then monitoring frequency increases, but the apparatus cannot handle viscous phosphoric acid samples effectively
Solution Approach 1:
The apparatus applies pressure (parameter change) to the phosphoric acid sample during filtration to accelerate the process and handle viscous samples effectively. By controlling pressure parameters, the system achieves rapid sampling speeds while maintaining the ability to process viscous phosphoric acid without clogging or delays.
Solution Approach 2:
The filtration system is designed with universal capability to handle both liquid and viscous phosphoric acid samples through the same apparatus. The filter and pressure control mechanism work together to provide adaptable performance across different sample viscosities, enabling rapid sampling regardless of sample characteristics.
