Split-Door Cell Culture Layout for Observation Without Contamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic culture devices lack the ability to efficiently set conditions while allowing direct observation of the flow path and operation of the device, requiring separate computer operation and hindering efficient workflow.
Innovation Solution
The automatic culture device features a horizontally arranged incubator and flow path unit with a front door divided into upper and lower parts, allowing the upper door to be lifted upward for observation and operation of a display unit and power supply, and the lower door to be pulled downward for access, enabling operation with either door state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the front door is kept closed for contamination prevention, then contamination risk is reduced, but direct observation of the flow path and operation becomes difficult
Solution Approach 1:
The front door is segmented into an upper door and a lower door that can be opened independently. The upper door can be opened for observation and operation of the display unit without opening the lower door, allowing monitoring while maintaining contamination prevention in the lower culture area.
Solution Approach 2:
The display unit and operation interface are relocated to the upper door area, allowing users to interact with the device from a different spatial dimension (upper portion) while the main culture area remains protected (lower portion).
2Ease of operation
If a separate computer is used for operation, then device functionality is maintained, but direct observation of the flow path during operation becomes impossible
Solution Approach 1:
The display unit and operation interface are integrated directly into the front door structure of the culture device, merging the control function with the observation window. This allows users to operate the device and observe the flow path simultaneously through the transparent upper door.
Solution Approach 2:
The transparent upper door serves as an intermediary element that simultaneously provides mechanical protection, optical transparency for observation, and mounting surface for the display unit and operation interface.
3Ease of operation
If the upper door is opened for observation and operation, then usability is improved, but contamination risk may increase
Solution Approach 1:
The front door is divided into upper and lower sections that can be opened independently. The upper door can be opened for observation and operation without opening the lower door that protects the culture area, minimizing contamination risk while maintaining usability.
Solution Approach 2:
The upper door is made transparent to allow observation, while the lower door maintains protection functionality. This local differentiation of properties (transparency vs. protection) allows simultaneous observation and contamination prevention.

AI summary
The automatic culture device includes an incubator capable of accommodating at least one cell culture vessel, and a flow path unit configured to supply gas and liquid necessary for cell culture to the cell culture vessel. The incubator and the flow path unit are arranged horizontally in parallel. The automatic culture device includes a front door capable of covering front surfaces of both the incubator and the flow path unit. The front door has a structure divided into upper and lower parts, the front door on an upper side can be lifted upward and includes a display unit capable of displaying a state of the automatic culture device and/or an operation unit capable of operating the automatic culture device, and the front door on a lower side can be opened by being pulled downward.
