Cell Culture Cabinet Airflow Control and Consumable Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cell culture apparatuses face challenges in automating culture medium replacement and preventing contamination due to disturbed airflow when supplying consumables, which affects efficiency and operating time.
Innovation Solution
The apparatus features a cabinet with strategically positioned aspiration ports and consumable supplying parts, where consumables with lids are placed near aspiration ports to prevent contamination and those without lids are positioned midportion to reduce work hours and contamination risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If consumables are supplied through an opened window in the cabinet, then supply work efficiency is improved, but contamination occurs due to disturbed airflow
Solution Approach 1:
The cabinet interior is divided into different airflow control zones: a first airflow control region with a first airflow controller near the window for incoming air, and a second airflow control region with a second airflow controller away from the window for outgoing air. This local differentiation allows simultaneous supply efficiency and contamination prevention by controlling airflow in specific areas.
Solution Approach 2:
Airflow controllers act as intermediaries between the opened window and the cabinet interior, regulating and directing air flow to prevent contamination while maintaining supply efficiency. The controllers mediate the interaction between external air and internal environment.
2Object-affected harmful factors
If consumables with lids are disposed at inner peripheral portions, then contamination is prevented, but work hours increase
Solution Approach 1:
The cabinet interior is segmented into multiple consumption supplying parts: first consumption supplying parts at inner peripheral portions for lid-equipped consumables, and second consumption supplying parts at midportions for lidless consumables. This segmentation allows parallel access to different consumable types, reducing total work hours while maintaining contamination prevention for sealed items.
Solution Approach 2:
The system provides more access points than traditionally used - both inner peripheral portions and midportions are utilized for different consumable types. This excessive action of providing multiple access points reduces the time needed to retrieve consumables while maintaining contamination prevention where needed.
3Productivity
If multiple consumption supplying parts are disposed in the cabinet, then supply work efficiency is improved, but device complexity increases
Solution Approach 1:
Multiple consumption supplying parts serve universal functions: all parts can supply consumables, but they are differentiated by location and airflow control characteristics. The first and second airflow controllers both perform air flow regulation but in different regions, providing multi-functionality without proportionally increasing complexity.

Function Achieved in This Case
This layout improves supply work efficiency and minimizes contamination by controlling airflow, reducing the risk of dust entry and maintaining cleanliness within the cabinet, while also reducing the time required for operations.
Implementation Method 1
a first airflow controller disposed in the cabinet and controlling airflow in a first airflow control region; and a second airflow controller disposed in the cabinet and controlling airflow in a second airflow control region

AI summary
An apparatus for culturing cells of the present disclosure includes: a cabinet that has a main surface and a side surface, the main surface having a window; a main surface aspiration port disposed at the main surface of the cabinet; and a side surface aspiration port disposed at the side surface of the cabinet. In the cross section of the cabinet taken along the horizontal direction, a first vessel supplying part for supplying a first vessel is disposed at a midportion of the cabinet, and a second vessel supplying part for supplying a second vessel is disposed at an inner peripheral portion of the cabinet. The first vessel supplying part has a first lid capable of entirely covering the first vessel supplying part. The first vessel has no lid. The second vessel supplying part has no lid. The second vessel has a second lid.
