Movable Platform Coordination for Robotic IV and Syringe Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pharmaceutical preparation systems lack efficient mechanisms for synchronizing the movement of platforms and manipulators along intersecting axes to establish fluid interfaces between different containers, such as IV bags and syringes, which hinders precise and automated fluid transfer processes.
Innovation Solution
A pharmaceutical preparation system is designed with a platform and manipulator that move linearly along intersecting axes, controlled by a controller to synchronize their movements, enabling fluid interfaces between containers, including IV bags and syringes, for efficient fluid transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a pharmaceutical preparation system uses separate platforms and manipulators for container handling, then the system can perform multiple operations simultaneously, but the lack of synchronized movement control prevents precise fluid interface alignment between containers
Solution Approach 1:
The patent combines the control of platform movement and manipulator movement into a single synchronized control system. The controller coordinates the linear displacement of the platform along the first axis and the manipulator along the second axis simultaneously, ensuring that both components move in a coordinated manner to achieve precise fluid interface alignment while maintaining parallel operation capability.
Solution Approach 2:
The system employs a controller that monitors and adjusts the positions of both the platform and manipulator in real-time. By providing feedback control, the system can detect position deviations and make corrective adjustments to maintain precise alignment of the fluid interface between containers, even during simultaneous operations.
2Adaptability or versatility
If the system uses intersecting axes for platform and manipulator movement, then the workspace flexibility is improved, but the complexity of coordinating movements along multiple axes increases
Solution Approach 1:
The system uses dynamic control to manage the intersecting axes movement. The controller continuously adjusts the motion parameters of both the platform and manipulator based on their relative positions and the required fluid interface alignment. This dynamic coordination allows the system to maintain workspace flexibility while managing the complexity of multi-axis movement through adaptive control strategies.
3Extent of automation
If automated control is implemented for synchronizing platform and manipulator, then human intervention is reduced, but the control system complexity increases
Solution Approach 1:
The controller is designed as a multi-functional device that performs multiple tasks: coordinating platform movement, controlling manipulator motion, synchronizing their movements, and maintaining fluid interface alignment. By consolidating these functions into a single universal control system, the patent achieves high automation while managing complexity through functional integration rather than separate dedicated systems for each function.
