Gripping Element for Removing U-Shaped Winding Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for removing U-shaped winding elements from setting tools are time-consuming, as they require individual extraction from recesses, making the process inefficient.
Innovation Solution
A method involving a gripping element with teeth that presses an engagement contour into the rod sections, allowing for simultaneous gripping and rotation of multiple winding elements, followed by radial inward pressing and sliding bevels to facilitate form-fitting removal, utilizing sliders to exert clamping forces and rotate the tool parts to disengage the elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If U-shaped winding elements are pulled out individually from the recesses of the setting tool, then the removal process is simple and straightforward, but the time required for removal becomes very long
Solution Approach 1:
Multiple individual removal operations are merged into a single collective operation. The gripping element is designed to simultaneously engage multiple rod sections of different winding elements, allowing them to be removed together as a group rather than one by one, thus dramatically reducing total removal time while maintaining operational simplicity
Solution Approach 2:
The gripping element is segmented into multiple gripping sections or teeth, each capable of engaging a separate rod section. This segmentation allows the single gripping element to simultaneously hold multiple winding elements, enabling parallel removal operations without increasing overall device complexity
2Productivity
If multiple winding elements are gripped and removed simultaneously using a gripping element, then removal time is significantly reduced, but the device complexity increases
Solution Approach 1:
The gripping element serves multiple functions: it simultaneously grips multiple rod sections, applies extraction force, and can be integrated with the setting tool structure. This multi-functionality reduces the need for separate components for each function, thereby increasing productivity without proportionally increasing device complexity
Solution Approach 2:
The gripping element is designed to automatically engage with the rod sections through form-fitting contours that match the geometry of the rod sections. This self-engaging mechanism reduces the need for complex control systems or multiple actuators, allowing simultaneous gripping of multiple elements with a simple, self-service mechanism
