Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated cell culture systems face issues with long-term stability and efficiency due to moisture-related failures and high maintenance costs, making it difficult to continuously culture cells for the development of artificial organs like skin, liver, or heart.
Innovation Solution
An automated 3D cell culture system with a first body containing a cell culture space and a medium storage space separated by a partition wall with a drain hole, using a communication pipe for siphon-driven medium exchange and a second body for medium recovery and observation, allowing for continuous medium supply and cell observation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated cell culture devices are used to enable long-term continuous culture, then productivity and efficiency are improved, but reliability deteriorates due to frequent failures from internal moisture accumulation
Solution Approach 1:
The patent extracts the harmful internal moisture from the automated cell culture device by introducing a communication pipe that connects the culture space to the external environment. This pipe enables continuous drainage of condensed moisture, preventing accumulation inside the device and thereby maintaining reliability during long-term operation while preserving productivity.
2Productivity
If medium exchange is performed manually to maintain cell culture, then device complexity is reduced, but productivity deteriorates due to frequent interruptions and contamination risks
Solution Approach 1:
The patent implements a self-service mechanism where the communication pipe automatically drains condensed moisture from the culture space to the external environment without requiring manual intervention. This passive drainage system operates continuously based on gravitational and pressure differential principles, enabling the device to maintain itself during long-term culture operations.
3Reliability
If the culture space is sealed to prevent contamination, then reliability is improved, but harmful factors worsen due to internal moisture accumulation
Solution Approach 1:
The communication pipe serves as an intermediary element that reconciles the contradiction between sealing the culture space and preventing moisture accumulation. The pipe is positioned such that it allows moisture to pass through from the culture space to the external environment while maintaining the sealed integrity of the culture space, thus preventing both contamination and moisture-related failures.
4Ease of operation
If automated medium supply systems are implemented to reduce maintenance costs, then ease of operation is improved, but device complexity increases leading to higher maintenance requirements
Solution Approach 1:
The patent replaces complex mechanical automated medium supply systems with a passive gravity-based drainage system. The communication pipe utilizes gravitational force and pressure differentials to automatically drain condensed moisture, eliminating the need for pumps, valves, or other complex mechanical components. This substitution maintains ease of operation while significantly reducing device complexity and maintenance requirements.

AI summary
This application relates to an automated three-dimensional (3D) cell culture system. The system includes a first body including a cell culture space in which a scaffold, on which cells are cultured, is provided and the cells are cultured thereon, and a medium storage space which is partitioned from the cell culture space by a first partition wall, in which a medium is provided and stored, and which surrounds the cell culture space, wherein the first partition wall has a drain hole to communicate the medium storage space with the cell culture space. The system also includes a communication pipe provided at the first partition wall to drain the medium of the cell culture space to the outside by a siphon action. The system further includes a second body including a medium recovery space located under the first body and recovering and externally draining the medium drained through the communication pipe.
