Robot Gripper Finger Longitudinal Plug-in Tip Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gripper systems for robot systems face complexity in replacing gripper tips, requiring intricate disassembly and reconnection of electrical and pneumatic connections, which complicates the process and increases the time needed for task adaptation and maintenance.
Innovation Solution
A gripper finger design featuring a longitudinal plug-in connection between the gripper tip and jaw, allowing for simple linear movement for attachment and detachment, with a locking mechanism that secures the connection against tilting and provides a predefinable locking force, eliminating the need for additional tools or complex movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If gripper tips are made exchangeable for different tasks, then adaptability is improved, but device complexity increases due to intricate disassembly and reconnection requirements
Solution Approach 1:
The gripper system is divided into modular components: gripper jaw, gripper tip, and connecting element. The connecting element integrates multiple functions (mechanical connection, electrical connection, pneumatic connection) into a single replaceable unit, allowing the gripper tip to be exchanged as a complete module without complex disassembly of individual connection lines.
Solution Approach 2:
The patent combines mechanical connection (connecting element with connecting socket), electrical connections (electrical conductors), and pneumatic connections (pneumatic lines) into a single integrated connecting element. This merging allows all connections to be established or disconnected simultaneously through one simple operation, reducing overall system complexity despite enabling exchanges of multiple connection types.
2Ease of operation
If multiple connection types are integrated in the connecting element, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The connecting element is designed as a universal interface that handles mechanical attachment, electrical power and signal transmission, and pneumatic fluid delivery all through a single component. This multi-functionality allows one standardized part to replace multiple separate connection mechanisms, simplifying operation while the precision requirements are managed through standardized manufacturing processes.

AI summary
A gripper finger for grasping objects includes a gripper jaw and a gripper tip which extends with a gripper axis along a longitudinal direction. The gripper tip is detachably connected to the gripper jaw by a connecting element. The connecting element can be locked with a connecting socket extending in the longitudinal direction in the form of a plug-in connection in such a manner that in the locked state it is impossible for the gripper tip to tilt away in relation to the gripper axis and simultaneously the gripper tip is locked against the gripper jaw in relation to the longitudinal direction by a predefinable longitudinal locking force.
