Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handling and automated transfer of small, slippery, and magnetically adherent magnetic dipole rods in laboratory settings is challenging due to their size, surface properties, and magnetic interactions, which complicate separation and handling with existing robotic systems.
Innovation Solution
A gripping device with a ferromagnetic metal bolt and a channel system allows for magnetic adhesion and controlled movement of magnetic dipole rods, using a motor-driven mechanism to transition between positions for secure handling and release, integrated with a robot arm and magazine system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If magnetic dipole rods are handled with universal mechanical-clamping grippers, then general handling capability is achieved, but reliable handling is difficult due to small size and slippery surface
Solution Approach 1:
A magnetic intermediary element (magnet or ferromagnetic component) is introduced between the gripper and the magnetic dipole rod. This intermediary uses magnetic attraction to reliably grasp the small, slippery rod, overcoming the limitations of mechanical clamping alone and enabling reliable automated handling.
2Productivity
If magnetic dipole rods are separated by customary separation methods (vibratory feeders or sorting screws), then separation is achieved, but it is ineffective due to magnetic properties causing adherence
Solution Approach 1:
The magnetic properties of the dipole rods, which cause them to adhere and hinder separation, are converted into a benefit by using magnetic fields for active manipulation. Magnets or ferromagnetic elements in the handling system exploit the rods' magnetism to guide, separate, and position them reliably, turning the adherence problem into a controlled magnetic interaction.
3Measurement precision
If magnetic dipole rods are handled manually, then precise positioning is possible, but pre-fitting sample containers may not be possible depending on the process
Solution Approach 1:
Manual mechanical handling is replaced with an automated magnetic field-based system. Magnets or ferromagnetic components enable precise positioning and insertion of the magnetic dipole rods into sample containers through magnetic attraction and guidance, achieving both precision and automation simultaneously.
4Productivity
If magnetic dipole rods are positioned in sample containers, then sample preparation is completed, but laboratory equipment (e.g., scales) is disturbed by magnetism
Solution Approach 1:
The magnetic handling components (strong magnets or ferromagnetic elements) are extracted and isolated in the gripping device or handling mechanism, separated from the sensitive laboratory equipment like scales. This extraction allows magnetic dipole rods to be manipulated magnetically during transfer, while the interference source is removed from the vicinity of sensitive instruments, preventing disturbance.

Data Source
AI summary
The disclosure relates to a gripping device for transferring a magnetic dipole rod as well as to a robot with a robot arm, to which the gripping device is attached. The disclosure furthermore relates to a magazine for providing one or more magnetic dipole rods, to a system for transferring a magnetic dipole rod, and to the use of the system. The gripping device for a magnetic dipole rod has a metal bolt made of a ferromagnetic material, the diameter of which is smaller than the diameter of the magnetic dipole rod. The metal bolt can assume at least two different positions, wherein the dipole rod adheres to the front end of the metal bolt in the first position and is stripped off from the front end of the metal rod during the transition into the second position.
