Cylinder Tip Mounting Head for Automated Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current movement devices for objects, such as cell aggregates, lack automation in the suction and discharge process, resulting in low work efficiency due to manual operation and limited automation of suction force generation mechanisms.
Innovation Solution
A cylinder tip mounting head device with a motor-driven mechanism that includes a shaft member, first and second cylindrical rods, and a discharge rod, allowing for automated up-down movement to suck and discharge objects using a syringe and plunger system, with a coordinating mechanism for efficient object transfer and tip removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation or limited automation is used for suction and discharge, then device complexity is reduced, but productivity and work efficiency deteriorate
Solution Approach 1:
The patent combines the suction force generation mechanism, discharge mechanism, and cylinder tip mounting/removal mechanisms into a single integrated head device. The shaft member simultaneously controls the discharge rod for object discharge and coordinates the cylinder tip mounting/removal through the first cylindrical rod, reducing the need for separate mechanisms and improving productivity without proportionally increasing complexity.
Solution Approach 2:
The shaft member serves multiple functions: it generates discharge force through the discharge rod, controls the mounting and removal of the cylinder tip through the first cylindrical rod, and coordinates the overall operation timing. This multi-functionality reduces the number of separate components needed, addressing the contradiction between automation and complexity.
2Reliability
If a suction tip is used for sucking cell aggregates in liquid, then the suction function is achieved, but the suction tip must be discarded after single use due to contamination
Solution Approach 1:
The patent extracts the suction function from the cylinder tip itself and places it in the syringe, while the cylinder tip becomes a removable mounting structure. This allows the syringe (containing the suction pathway) to be replaced while retaining the cylinder tip mounting mechanism, reducing waste of the mounting structure and enabling more efficient resource utilization.
Solution Approach 2:
The design allows the syringe and cylinder tip to be separately replaced. The cylinder tip mounting mechanism and first cylindrical rod are recovered and retained in the head device, while only the consumable suction components (syringe and cylinder tip) are discarded after use. This reduces overall waste and improves cost efficiency.
3Productivity
If automation is implemented for suction and discharge operations, then productivity is improved, but device complexity increases
Solution Approach 1:
The head device is pre-configured with the discharge rod, first cylindrical rod, and shaft member connection mechanisms before operation. The coordinating mechanism for cylinder tip mounting/removal is pre-established, allowing automated operations to proceed without additional complex control systems during actual use, thus improving productivity without excessive complexity.

AI summary
A cylinder tip mounting head includes: a shaft member configured to move in an up-down direction; a first cylindrical rod, which is mounted to a lower end of the shaft member, which is configured to move in the up-down direction integrally with the shaft member, and which has a cylindrical space formed therein; a stationary second cylindrical rod, which has a housing space for housing the first cylindrical rod so that the first cylindrical rod is movable in the up-down direction, the stationary second cylindrical rod including, at a lower end, a syringe mounting portion to which a base end portion of the syringe is to be fitted; and a discharge rod housed in the cylindrical space in the first cylindrical rod, the discharge rod including, at a lower end, a plunger mounting portion to which a base end portion of the plunger is to be fitted. The discharge rod is configured to coordinate with the movement of the shaft member in the up-down direction so that the plunger mounted to the discharge rod reciprocates in the tubular passage in the syringe to suck the object into the tubular passage and discharge the sucked object.
