Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional mixing chamber is used to mix fluid and test sample, then the mixing function is achieved, but the process becomes time-consuming and complex to operate
Solution Approach 1:
The device segments the mixing process into two distinct locations: (1) preliminary mixing occurs in the sampling member where test sample is collected and initially mixed with fluid, and (2) final mixing occurs in the mixing chamber. This segmentation eliminates the need for manual intervention and reduces operational complexity while maintaining effective mixing functionality.
Solution Approach 2:
The sampling member performs preliminary mixing of the test sample with fluid before the mixture enters the main mixing chamber. This preliminary action prepares the sample in advance, reducing the workload and time required for subsequent mixing operations in the mixing chamber.
2Measurement precision
If excess test sample adheres to the sampling member surface, then complete sample collection is achieved, but measurement accuracy deteriorates due to sample loss
Solution Approach 1:
The device extracts excess test sample from the sampling member surface using a cleaning member. The cleaning member removes adhered sample and directs it into the mixing chamber, preventing sample loss and ensuring complete sample utilization for measurement, thereby improving measurement accuracy.
Solution Approach 2:
The cleaning member acts as an intermediary between the sampling member and the mixing chamber. It transfers excess sample from the sampling member surface to the mixing chamber, ensuring that no sample is wasted and all collected sample is utilized for the measurement process.
3Measurement precision
If excess test sample on sampling member is not removed, then sampling is complete, but measurement accuracy deteriorates due to changes in specimen amount
Solution Approach 1:
The cleaning member extracts excess test sample from the sampling member surface and directs it into the mixing chamber. This ensures that the total amount of specimen used for measurement is controlled and accurate, preventing measurement errors caused by unintended sample quantity variations.
Solution Approach 2:
The cleaning mechanism provides feedback control for sample quantity. By removing excess sample from the sampling member surface and directing it to the mixing chamber, the system ensures that the correct amount of sample is transferred for measurement, maintaining precise control over specimen quantity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The module enables quick operation and precise control of the test sample, reducing measurement errors and enhancing testing efficiency by ensuring accurate mixing and dilution of the sample before measurement.
Implementation Method 1
The puncturing structure is configured to penetrate the block member. The first state refers to the block member being intact without breakage, and the second state refers to an opening being formed on the block member after the sampling assembly is connected to the carrier.
Implementation Method 2
At least a portion of the fluid flows into the downstream of the flow path via the sampling member and mixes with the test sample in the sampling member.
Implementation Method 3
The sampling member is used to collect the test sample. A passage is formed in the sampling member, and the test sample is disposed in the passage.
Implementation Method 4
The flow path is used to guide the flow of a fluid. The storage chamber is fluidly connected to an upstream of the flow path.

AI summary
The disclosure provides a testing module including a carrier, a block member, and a sampling assembly. A flow path connects a storage chamber to a mixing chamber to guide the flow of a fluid. The block member is formed in the flow path to block the fluid from flowing from the storage chamber to the mixing chamber before the connection of the sampling assembly. When the sampling assembly which contains a test sample is connected to the carrier, the fluid mixes with the test sample and flows to the mixing chamber.
