Sheath Liquid Storage Unit with Detachable Support for Microparticle Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional microparticle measurement devices require complex and burdensome operations for setting sheath liquid, including attaching and moving heavy sheath tanks, which can lead to improper tube attachment and increased risk of contamination.
Innovation Solution
A fluid control device with a detachable support portion for sheath liquid storage units, sealed by pressurization, featuring a visible attachment mechanism and a through hole for efficient liquid feeding, along with a liquid drain unit and vibration control to simplify the setup and reduce contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sheath liquid is preserved in the sheath tank as it is, then the sheath liquid can be stored, but the setting operation becomes complicated and time-consuming
Solution Approach 1:
The sheath tank is divided into a tank body and a detachable support portion. The support portion can be separated from the tank body, allowing operators to handle only the lightweight support portion with the attached tube rather than the entire heavy tank, thereby simplifying the setting operation while maintaining storage functionality.
Solution Approach 2:
The support portion is extracted as a separate detachable component from the sheath tank. This extracted portion can be independently handled and attached to the clean bench, eliminating the need to move the entire heavy tank and reducing operational complexity.
2Reliability
If the entire sheath tank is carried, then the sheath liquid storage is secure, but the operator burden increases due to heavy weight
Solution Approach 1:
The sheath tank is segmented into a stationary tank body and a movable support portion. Only the lightweight support portion needs to be carried and positioned, significantly reducing the weight burden on operators while the tank body remains in place to provide stable storage.
Solution Approach 2:
The heavy tank body is left stationary while the essential support portion is extracted and moved independently. This separation allows operators to handle only the necessary lightweight component without bearing the full weight of the storage system.
3Reliability
If tube attachment is performed inside the clean bench, then the aseptic environment is maintained, but the tube may not be attached properly due to space constraints
Solution Approach 1:
The detachable support portion serves as an intermediary that can be prepared outside the clean bench and then transferred inside. This intermediary component allows tube attachment to be performed in a more accessible environment while maintaining the aseptic integrity of the clean bench when the support portion is positioned inside.
