Cell Suction Chip Holder for Self-Aligning Needle Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cell suction systems face challenges in accurately aligning the needle tip of a chip with the position of a cell to be sucked due to axial misalignment between the chip connection shaft and the chip base, leading to inefficiencies and labor-intensive operations when processing a large number of cells.
Innovation Solution
A cell suction system design that includes a chip container holder allowing movement of the chip and container relative to the chip connection shaft, utilizing a placement portion with a low-friction surface and regulatory mechanisms to eliminate axial misalignment, and incorporating rolling elements and holders to facilitate precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fixed chip container holder is used, then the structure is simple and stable, but axial misalignment occurs between the chip connection shaft and chip base
Solution Approach 1:
The chip container holder is designed with movable characteristics, allowing it to adjust its position dynamically. The holder can move the chip container in the axial direction relative to the chip connection shaft, enabling real-time alignment correction during the connection process. This dynamic adjustment capability eliminates axial misalignment while maintaining operational simplicity.
2Manufacturing precision
If manual alignment adjustment is required, then alignment precision can be improved, but operation time and labor increase
Solution Approach 1:
The chip container holder incorporates self-aligning mechanisms that automatically correct axial misalignment between the chip connection shaft and chip base. The system performs its own alignment function without requiring external manual intervention, thereby achieving high alignment precision while minimizing adjustment time and operational burden.

AI summary
A cell suction system includes a suction unit and a chip container holder. The suction unit includes a chip connection shaft to be connected to a chip base of a chip held in a chip container, and causes the chip to suck and hold a cell component of a cell or an entire cell from a needle tip of a needle portion, in a state in which the chip is connected to the chip connection shaft. The chip container holder holds the chip container so as to allow movement of the chip and the chip container relative to the chip connection shaft, to eliminate axial misalignment when the chip connection shaft is connected to the chip base of the chip held in the chip container.
