Sample Processing Transport System with Dual Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sample processing systems face inefficiencies in retesting due to long transport paths and clogging issues when samples need to be reanalyzed, which hampers the overall retesting efficiency.
Innovation Solution
A sample processing apparatus with multiple sample processing units and a transport system featuring two transport lines and a controller that determines the optimal route for post-tested racks based on retesting needs, allowing for selective re-routing of racks to either a first or second sample processing unit or directly to storage, thereby optimizing the transport path and reducing bottlenecks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sample rack is transported along the return line to the transport start position for retesting, then the sample can be retested, but the transport path becomes long causing bottlenecks and reducing retesting efficiency
Solution Approach 1:
The patent divides the transport system into two separate lines: a first transport line for transporting sample racks to sample processing units, and a second transport line for returning processed sample racks. This segmentation allows retesting to occur without using the return line, thus preventing bottlenecks and reducing transport time while maintaining retesting capability.
Solution Approach 2:
The patent introduces a third-dimensional routing option by providing a bypass line that connects the first transport line directly to the sample processing units, allowing sample racks to skip the return line entirely. This dimensional change in the transport topology eliminates the bottleneck caused by using the return line for retesting.
2Adaptability or versatility
If the sample rack is transported to the exit of the transport line and then returned via the return line, then the sample rack can be retested, but clogging occurs on the transport path when other samples are being processed
Solution Approach 1:
The patent segments the transport system into dedicated forward and return lines, allowing independent operation of each line. The first transport line can continuously supply sample racks to processing units without being blocked by retesting operations, while the second transport line handles returned racks separately, thus eliminating clogging and maintaining high transport efficiency.
Solution Approach 2:
The patent introduces a bypass line as an intermediary route that connects the first transport line directly to the sample processing units. This intermediary allows retesting to occur without interfering with the normal transport flow on the return line, thus preventing clogging while maintaining retesting flexibility.
3Reliability
If the transport of the sample rack is suspended until suctioning is complete, then the sample can be processed, but the transport path becomes clogged and retesting efficiency deteriorates
Solution Approach 1:
The patent segments the transport and processing operations by providing separate dedicated lines for forward transport and return transport. This allows the first transport line to continue moving sample racks without suspension, while processing occurs at the processing units. The bypass line enables retesting without requiring suspension of transport, thus maintaining both processing completeness and high retesting efficiency.

AI summary
A transport apparatus includes: a first transport line configured to transport a rack downstream along the transporting route; a second transport line configured to transport the rack upstream along the transporting route; and a controller including a processor and a memory that stores programs executable by the processor to: determine where to transport a post-tested rack according to whether or not retesting is necessary on any sample held in the post-tested rack; and according to a determination, instruct the transport apparatus to transport the post-tested rack selectively (i) along the first transport line either back to first sample processing unit, where the rack has been tested, or to a second sample processing unit located downstream of the first sample processing unit, or (ii) along the second transport line back from the first sample processing unit.
