Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pretreatment devices face issues with septum-attached containers floating from the container installation unit due to frictional resistance, leading to potential analysis errors and variations in results when liquids are sucked by a probe.
Innovation Solution
A pretreatment device with a container holding unit that securely accommodates septum-attached containers from the side surface direction, featuring a cap member to store the container vertically and a fixing unit with a shaft and flange portion to prevent floating, ensuring stable operation during probe movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a probe is inserted into a septum-attached container to suck liquid, then liquid extraction is achieved, but the container may float from the installation unit due to frictional resistance
Solution Approach 1:
The container holding unit is divided into separate functional components: a holder that secures the container body and a separate fixing mechanism (claw portion) that prevents floating. This segmentation allows each component to address specific stability issues independently, ensuring reliable container positioning during probe operation.
Solution Approach 2:
The claw portion acts as an intermediary fixing mechanism between the container holder and the installation unit. It provides an additional securing interface that prevents the container from floating during probe insertion and liquid extraction, without interfering with the primary holding function.
2Reliability
If the container is securely fixed to prevent floating, then analysis reliability is improved, but device complexity increases
Solution Approach 1:
The claw portion is designed to automatically engage with the container holder and provide fixing functionality without requiring additional actuators or complex control mechanisms. The elastic deformation of the claw portion creates self-locking behavior that maintains container stability throughout the analysis process.
Solution Approach 2:
The claw portion utilizes elastic deformation of a flexible component to achieve the fixing function. This flexible element can deform to accommodate the container and then maintain a secure grip, providing reliable fixation with minimal structural complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device efficiently and reliably prevents septum-attached containers from floating, minimizing analysis errors and maintaining consistent results by securely fixing the container holding unit to the installation unit, even during probe movement.
Implementation Method 1
an elastic member that elastically deforms to come into contact with an outer surface of the septum-attached container so as to prevent the septum-attached container from floating

AI summary
A pretreatment device for performing pretreatment using a liquid sucked by a probe from an inside of a septum-attached container includes: a container holding unit which has a space for accommodating the septum-attached container and is provided with a hole into which the probe is inserted with respect to a septum of the septum-attached container to be stored; an installation unit in which the container holding unit is detachably installed; and a fixing unit which fixes the container holding unit to the installation unit in a state where the container holding unit is detachably installed in the installation unit, to solve the above-described problem.
