Robotic Plug-In Gripper With Actuator for Strain-Free Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for establishing plug-in connections, such as those used in charging electric vehicles, are time-consuming, complex, and not universally applicable due to mechanical strain on plugs and sockets.
Innovation Solution
A device comprising a gripper with a plug-in actuator, handling unit, and control system that automates the plug-in process, allowing for a more reliable and efficient connection by using a plug-in actuator to move the plug into position, optionally with a compensation unit to prevent strain transmission and a latching device for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a robot with handling unit is used to move the plug to the socket, then automation is achieved, but the plug-in process becomes time-consuming and complex
Solution Approach 1:
The device is divided into two functional parts: a handling unit for positioning the plug near the socket, and a plug-in actuator integrated into the gripper for the final insertion. This segmentation allows each component to perform its specific function efficiently, reducing overall system complexity while maintaining automation.
Solution Approach 2:
The plug-in actuator serves as an intermediary mechanism between the handling unit and the plug. It takes over the final insertion task from the handling unit, simplifying the handling unit's role to only positioning while the actuator handles the precise plug-in action.
2Measurement precision
If search movements are used to determine correct plug-in position, then alignment is achieved, but the process becomes time-consuming
Solution Approach 1:
The handling unit performs preliminary positioning of the plug in close proximity to the socket before the final insertion. This preliminary alignment reduces or eliminates the need for time-consuming search movements during the actual plug-in process, as the plug is already positioned correctly for insertion.
3Reliability
If mechanical strain is applied to establish connection, then plug-in connection is achieved, but the solution is only possible for specific plugs and sockets
Solution Approach 1:
The plug-in actuator is designed as a universal mechanism that can accommodate different plug types and socket configurations. By providing a standardized actuation interface that works with various plug designs, the system achieves both reliable connections and broad adaptability across different connector types.
