Cell Seeding Layer Alignment for Individual Colony Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cell culture methods result in overlapping cell colonies on culture dishes, leading to the risk of picking up unintended cells during seeding.
Innovation Solution
A device comprising an accommodation layer with individual cell compartments and a passage layer with controlled through-holes allows for precise positioning and individual seeding of cells onto a culture dish, preventing overlap by adjusting the relative positions of the layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cells are placed randomly on the culture dish, then the cell seeding process is simple, but the cell colonies overlap and technicians cannot pick up cells from specific colonies
Solution Approach 1:
The device divides the culture dish surface into multiple independent through-holes, each serving as a separate seeding position. This segmentation allows cells to be placed in predetermined locations rather than randomly, preventing colony overlap while maintaining operational simplicity through the structured hole array.
Solution Approach 2:
The device acts as an intermediary tool between the cell source and the culture dish. By using the device with its predetermined through-hole pattern, technicians can achieve precise cell positioning without requiring manual precision, thus resolving the contradiction between ease of operation and positioning precision.
2Manufacturing precision
If a device with individual cell compartments and passage layer is used, then cell positioning precision is improved, but the device structure becomes more complex
Solution Approach 1:
The device is segmented into two functional layers: an accommodation layer for holding cells and a passage layer with through-holes for cell transfer. This segmentation enables precise positioning functionality while keeping each layer's structure relatively simple and manageable.
Solution Approach 2:
The passage layer serves multiple functions: it provides structural support, defines the through-hole positions for precise cell placement, and facilitates cell transfer from the accommodation layer to the culture dish. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.

AI summary
A device for cell seeding according to an exemplary embodiment includes a first layer and a second layer. The first layer includes a first accommodation space configured to accommodate a cell to be seeded. The second layer includes a first through-hole wider than the cell and is positioned vertically below the first layer. Then, the device for cell seeding forms a first state in which the first through-hole is positioned at a bottom surface of the first accommodation space by changing a relative position between the first layer and the second layer in a horizontal direction.
