Gripping Arms With Detachable Pivoting Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gripping devices are prone to damage during unintended collisions with rigid surfaces due to deformation of gripping arms and their holders, especially when actuated incorrectly or placed at high speed.
Innovation Solution
A gripping device with movable gripping arms that can detach from a carrier when a defined force is applied, particularly from below, to prevent damage upon collision, featuring mechanical connections with guide pins and grooves that allow for pivoting movement and easy reattachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If gripping arms are made rigid and firmly connected to the carrier, then gripping force and stability are improved, but damage occurs during unintended collisions with rigid surfaces
Solution Approach 1:
The mechanical connection between the gripping arm and carrier is designed to be dynamically changeable - firmly connected during normal operation to provide stability and gripping force, but capable of detaching when excessive force is detected during collisions, thus preventing damage while maintaining strength during useful work
2Object-affected harmful factors
If gripping arms are made detachable to prevent collision damage, then protection against damage is improved, but device complexity increases
Solution Approach 1:
The mechanical connection is segmented into detachable components (gripping arm, carrier, guide pins, guide grooves, and latching elements) that can separate when needed, allowing the system to protect against damage through controlled separation while maintaining relatively simple individual components
3Reliability
If gripping arms are firmly connected to ensure stable object handling, then handling reliability is improved, but deformation occurs during incorrect actuation or high-speed placement
Solution Approach 1:
The connection transitions from a static firmly-connected state during reliable object handling to a detachable state when excessive force is detected, allowing the system to maintain handling reliability under normal conditions while preventing structural deformation through automatic detachment during incorrect actuation or high-speed placement

AI summary
The gripping device (1) has two gripping arms (9), which are provided for retaining or releasing an article (3) or packaged goods in a distance variable manner. The gripping arms are arranged at a common carrier (5). Each gripping arm is detached by a defined application of force (F), particularly from downside or by setting on the gripping arm on a rigid surface or by a collision of the gripping arm with a firm body under overcoming of defined retaining strength of the carrier. An independent claim is also included for a method for detaching gripping arms from a vertically and horizontally movable carrier of a gripping device.
