Pretreatment Device Container Positioning and Replenishment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pretreatment devices require a complex operation to replenish pretreatment containers before starting analysis, even when a sufficient number of containers are available, leading to inefficient use and increased operational complexity.
Innovation Solution
A pretreatment device with a container holding unit, pretreatment unit, and position setting receiving unit that allows for flexible selection of pretreatment containers and automatic positioning based on previous usage, enabling the start of pretreatment without the need for manual replenishment, and includes a notification system for insufficient container numbers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If pretreatment containers are held at multiple holding positions and used in a specific order, then continuous pretreatment can be performed, but the operation becomes complicated requiring manual replenishment before analysis
Solution Approach 1:
The system automatically manages pretreatment container replenishment by detecting when containers are needed and prompting the user to replenish only at that moment. The container holding unit and control unit work together to self-monitor container status and initiate replenishment operations only when necessary, eliminating the need for manual intervention before each analysis.
Solution Approach 2:
The system performs preliminary detection of container status and prepares for replenishment before actual depletion occurs. The control unit monitors the number of pretreatment containers and issues replenishment prompts in advance, allowing users to prepare containers before they are absolutely needed, thus maintaining continuous operation without interruption.
2Reliability
If pretreatment containers are replenished before analysis starts, then sufficient containers are available for next analysis, but the operation is unnecessarily complicated
Solution Approach 1:
The control unit continuously monitors the number of pretreatment containers in the holding unit and provides feedback to the user through replenishment prompts. This feedback mechanism ensures containers are replenished based on actual usage status rather than predetermined schedules, maintaining reliability while simplifying operations by eliminating unnecessary replenishment actions.
Solution Approach 2:
The system self-monitors container inventory levels and intelligently determines when replenishment is actually needed. Rather than requiring manual replenishment before every analysis, the system automatically tracks usage and only prompts users when container numbers fall below required thresholds, ensuring availability while reducing operational complexity.
3Productivity
If multiple holding positions are used for pretreatment containers, then sequential pretreatment is enabled, but the device complexity increases
Solution Approach 1:
The container holding unit is designed with multiple holding positions that can accommodate different types of pretreatment containers. The control unit universally manages these positions, tracking container numbers and coordinating replenishment across all positions. This multi-functional design enables sequential pretreatment while the centralized control logic keeps the system manageable despite increased complexity.

AI summary
Provided are a pretreatment device capable of starting pretreatment in a simple operation, and an analysis system provided with the pretreatment device. A container holding unit 12 holds pretreatment containers into each of which a sample is injected, at a plurality of holding positions. A pretreatment unit sequentially performs pretreatment by using the pretreatment containers held at the holding positions of the container holding unit 12 in a specific order. A controller configured to receives a setting of the holding position of a pretreatment container to be used first among the plurality of holding positions in the case where a series of pretreatments using the plurality of pretreatment containers is started by the pretreatment unit.
