Solution Overview

Problem

In medical facilities with limited space, existing sample processing systems require separate rows for racks being supplied to and collected from sample processing apparatuses, inefficiently utilizing the available area.

Innovation Solution

A rack export-import unit that allows for efficient arrangement and transportation of racks within a limited area by using a setting section, export section, and import section, with transfer units and a transfer prevention section to manage the flow of racks, enabling them to be aligned and transported in a way that optimizes space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If racks are arranged in separate rows for supply and collection, then rack management is simplified, but the installation area increases

Engineering Contradiction:
Improverack managementVSAvoidinstallation area
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent combines the rack supply function and rack collection function into a single integrated unit. The same physical space serves dual purposes: racks are supplied to the measurement unit and collected from it within the same compact structure, eliminating the need for separate rows and reducing overall installation area while maintaining operational simplicity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The rack export-import unit performs multiple functions within a single device: it serves as both a rack storage area and a rack transport interface. The unit can both receive racks from the measurement unit and supply racks to it, making the system more space-efficient by eliminating dedicated separate areas for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Area of stationary object

If racks are compactly arranged in a single unit, then installation area is reduced, but rack transfer management becomes more complex

Engineering Contradiction:
Improveinstallation areaVSAvoidrack transfer management
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent introduces a transfer prevention mechanism that acts as an intermediary control element. This mechanism automatically prevents racks from being transferred at inappropriate times or in incorrect directions, simplifying the overall management complexity by providing automatic control rather than requiring complex manual coordination of multiple transfer operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The rack export-import unit employs dynamic control mechanisms that adapt to the current state of rack loading and processing. The transfer prevention section dynamically adjusts its operation based on whether racks are present, whether the measurement unit is ready to receive racks, and the current operational state, thereby managing complexity through adaptive behavior rather than fixed complex procedures.

Inventive Principle:
Principle #15Dynamics

AI summary

[TECHNICAL PROBLEM] To provide a measurement system, a rack export-import unit, and a method of exporting and importing racks that can set racks with efficient use of a limited area. [SOLUTION TO PROBLEM] Measurement system 100 comprises measurement unit 10, transport unit 20, and rack export-import unit 30. Measurement unit 10 measures a sample contained in a sample container. Transport unit 20 comprises first transporter 21 that transports a rack capable of holding sample containers in a longitudinal direction of the rack to measurement unit 10, and second transporter 22 that transports the rack from measurement unit 10. Rack export-import unit 30 is capable of setting racks thereon, is made capable of transferring each of the set racks in a lateral direction of the rack, exports the rack to first transporter 21 from one end side of rack export-import unit 30, and imports the rack transported by second transporter 22 from another end side of rack export-import unit 30.
