Solution Overview

Problem

Conventional culture devices are inadequate for individually setting cell culture environments and identifying secretor factors like cytokines and exosomes, as they lack the ability to separate wells for independent filtration and analysis.

Innovation Solution

A culture vessel system comprising two connected vessels made of transparent thermoplastic material, with a connecting mechanism allowing for watertight communication, a filter for fractionating secretory substances, and separate rooms for independent environment control and observation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple cell species are cultured in different wells on a common vessel body, then cell interaction can be observed through shared liquid medium, but individual culture environments cannot be set for each cell species

Engineering Contradiction:
Improveability to set individual culture environmentsVSAvoidstructure of common vessel body
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention divides the culture system into separate first and second vessels, each capable of independent environment control. This segmentation allows each vessel to maintain distinct culture conditions while still enabling cell interaction through controlled connection, resolving the contradiction between individual environment control and interaction observation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from a two-dimensional well plate structure to a three-dimensional connected vessel system. By stacking vessels vertically and connecting them through side openings, the system achieves independent environment control in each vessel while maintaining liquid medium communication, thus enabling both individual environment setting and cell interaction observation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Measurement precision

If multiple cell species are cultured in different wells on a common vessel body, then cell interaction can be observed, but secretor factors cannot be identified due to inability to separate wells for filtration

Engineering Contradiction:
Improveidentification of secretor factorsVSAvoidfiltration operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The separate first and second vessels can be independently connected or disconnected. When connected, cells interact through shared medium; when disconnected, each vessel can be independently filtered to identify secretor factors. This segmentation resolves the contradiction between observing cell interactions and identifying secretor factors.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection between vessels is made dynamic rather than fixed. The vessels can be connected to observe cell interactions or disconnected to perform separate filtration operations for secretor factor identification. This dynamic configuration allows the system to adapt to different experimental needs, resolving the contradiction between interaction observation and factor identification.

Inventive Principle:
Principle #15Dynamics

3Reliability

If vessels are connected to allow liquid medium communication, then cell interaction can be observed, but watertight connection is difficult to achieve

Engineering Contradiction:
Improvewatertight connectionVSAvoidconnecting mechanism
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The connecting mechanisms are pre-formed on the vessels during manufacturing. The first and second vessels are equipped with integrated connecting structures that align and seal when brought together, ensuring watertight connection without requiring complex assembly procedures. This preliminary action resolves the contradiction between reliable watertight connection and ease of manufacture.

Inventive Principle:
Principle #10Preliminary action

AI summary

The present invention relates to a culture vessel which can be broadly applied to culture, regeneration, manufacture, observation and the like of targets such as cells, organs, and microorganisms. In the culture vessel of the present invention, a first vessel 10 and a second vessel 20 each being a closed-bottom, open-top vessel are provided. In the first vessel 10 and the second vessel 20, a sideways-facing opening 12 and a sideways-facing opening 22 are formed. The opening 12 and the opening 22 communicate in a watertight manner when the openings 12, 22 are connected face to face.
