Sample Rack Transport System Error Restart via Intermediary Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In large-scale sample rack transport systems, identifying and resolving errors between transport line units is cumbersome due to the distance between display sections and transport line units, increasing the user's workflow length and complexity.
Innovation Solution
Implementing a control apparatus that allows users to restart the sample rack transport system by operating a start/stop key on a different transport apparatus, which communicates with the control apparatus to determine and confirm the resolution of issues, and includes notification features like alarms and lights to indicate errors and their resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display section is provided to show error information, then error identification capability is improved, but the distance between the display section and the transport line unit increases the user's workflow length
Solution Approach 1:
A notification section is introduced as an intermediary device that bridges the gap between the error source (transport line unit) and the user. This notification section provides visual and audible notifications directly at the transport line unit, eliminating the need for users to travel to a centralized display section to identify errors, thus reducing workflow length while maintaining error identification capability.
2Ease of operation
If a start/stop key is provided in each transport line unit, then ease of operation is improved, but the user cannot determine which unit has the error without checking the display section
Solution Approach 1:
The notification section acts as an intermediary that provides localized error information at each transport line unit. When an error occurs, the notification section activates to inform users of the specific unit's status, enabling them to operate the start/stop key on the correct unit without needing to check a centralized display section, thus maintaining both ease of operation and error location information.
3Reliability
If the system requires confirmation of error resolution before restart, then system reliability is improved, but the operational complexity increases
Solution Approach 1:
The notification section provides self-service functionality by automatically monitoring and indicating whether an error has been resolved. When the error condition is cleared, the notification section automatically updates its state, eliminating the need for complex manual confirmation procedures while maintaining system reliability through automatic error resolution detection.

AI summary
A sample rack transport system comprising: a plurality of transport apparatuses which are connected so as to transport a sample rack to a plurality of sample processing apparatuses; and a control apparatus which communicates with the plurality of transport apparatuses and controls the transport of the sample rack by the plurality of transport apparatuses, wherein at least one of the plurality of transport apparatuses includes a transmission switch which is operated by a user to transmit a signal to the control apparatus, and when the transport of the sample rack has stopped due to a trouble which occurred in one of the plurality of transport apparatuses, responsive to an operation of a transmission switch of another transport apparatus, the control apparatus restarts the transport of the sample rack by the plurality of transport apparatuses. Also, a method for transporting a sample rack.
