Solution Overview

Problem

Conventional automated sample processing systems experience delays in transporting samples to automatic analyzers due to unnecessary units in the processing path and limited storage capacity, leading to congestion and increased time for sample measurement.

Innovation Solution

The dispensing unit is positioned on the most downstream side, equipped with mechanisms to stop and direct samples, read vessel IDs, and communicate with a computer to control sample transport, allowing direct transport to the analyzer without passing through additional units, and providing dedicated discharge sections for each vessel type.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If processing units such as storage unit and vessel closing unit are located at positions on the downstream side relative to dispensing unit, then sample processing functions are complete, but sample transport time to automatic analyzer is increased

Engineering Contradiction:
Improvesample transport timeVSAvoidprocessing path complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The system divides the transport path into separate segments: one path for samples requiring storage/closing operations and another direct path for samples that can be transported immediately after dispensing. This segmentation allows different samples to take different routes, reducing overall transport time for urgent samples.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system adds a dimensional aspect to the transport architecture by creating parallel transport paths (different routes) rather than a single linear path. This allows samples to be routed through different dimensions of the transport system, with some samples bypassing intermediate units entirely.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If storage unit capacity is limited, then system size is controlled, but sample transport and discharge must be stopped when capacity is exceeded

Engineering Contradiction:
Improvecontinuous sample transportVSAvoidstorage unit capacity
Core Design Contradiction:
ProductivityVSVolume of stationary object

Solution Approach 1:

The system dynamically adjusts sample routing based on real-time storage unit capacity. When storage capacity is available, samples are routed through the storage path; when capacity is exceeded, samples are automatically routed through the direct transport path. This dynamic adaptation ensures continuous productivity without requiring large storage capacity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the transport path parameter based on storage unit capacity status. By monitoring capacity levels and adjusting routing decisions, the system maintains continuous sample flow without being constrained by fixed storage capacity limitations.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If multiple samples are transported on the same transport line, then system complexity is reduced, but transport line congestion occurs

Engineering Contradiction:
Improvesample throughputVSAvoidsample transport speed
Core Design Contradiction:
ProductivityVSSpeed

Solution Approach 1:

The system segments the transport flow by creating separate paths for different sample types and priorities. Urgent samples that need rapid analysis are routed through the direct path without mixing with samples requiring storage or closing operations, preventing congestion and maintaining high transport speed for critical samples.

Inventive Principle:
Principle #1Segmentation

AI summary

After being dispensed, a sample that needs to be quickly measured passes through another unit and is transported to an automatic analyzer. An automated sample processing system includes a plurality of units that are provided for functions of processing a sample and combined so as to form the system. The plurality of units include at least a dispensing unit that dispenses the sample stored in a sample vessel into another sample vessel. The automated sample processing system has at least one discharge line that discharges the sample from the dispensing unit to a transport line; a line that is perpendicular to the discharge line; and a reverse direction transport line that transports the sample in a direction reverse to a direction in which the sample loaded in the system is transported to the dispensing unit. The sample that is processed by the dispensing unit is transported to a storage unit located on the upstream side of the system, through the reverse direction transport line.
