Press Collar Drive Unit With Visual Jaw Connection Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing drive units for press slings lack a secure connection mechanism, leading to potential user errors and safety risks due to the difficulty in visually verifying the correct seating of connecting bolts, which can result in damage or injury.
Innovation Solution
The drive unit incorporates marked connecting elements on the jaws of the pressing tongs, ensuring a secure connection by providing a visual indication of correct alignment through markings that are completely covered by the press loop segments when properly connected, preventing incomplete insertions and ensuring safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the connecting bolt is inserted into the recess without visual verification, then the connection process is fast, but the connection reliability is poor and safety risks increase
Solution Approach 1:
The patent applies visual markings (color changes or pattern changes) on the connecting elements to indicate connection status. The marking is completely covered by the press loop segment when correctly connected, providing immediate visual feedback to the user about whether the connection is proper, thus maintaining fast connection speed while ensuring high reliability
Solution Approach 2:
The patent implements visual feedback through markings that change appearance based on connection status. When the connecting bolt is properly inserted and the press loop segment is correctly positioned, the marking is completely covered, providing clear feedback to the user that the connection is secure, preventing incomplete insertions and ensuring safety
2Device complexity
If the recess is obscured by the press loop segment, then the device structure is compact, but the ease of operation deteriorates due to inability to visually verify connection
Solution Approach 1:
The patent uses visual markings on the connecting elements that are completely covered by the press loop segment when correctly connected. This allows the structure to remain compact with the press loop segment obscuring the recess, while simultaneously enabling easy visual verification of proper connection through the presence or absence of the visible marking
Solution Approach 2:
The patent introduces a visual marking as an intermediary indicator between the connecting elements and the user. The marking serves as a mediator that communicates connection status without requiring the user to see the actual connecting bolt or recess, thus maintaining structural compactness while improving ease of operation

AI summary
The invention relates to a drive unit for use with a press collar for pressing two workpieces, comprising a drive (10) and pressing pliers (18) connected to the drive (10), the pressing pliers (18) having two jaws (16). The jaws (16) of the pressing pliers (18) can be moved toward each other by means of the drive (10) in order to close the press collar (12) and to press the two workpieces (33). Furthermore, the two jaws (16) each have a first connecting element (24) for connecting to a second connecting element (26) of the press collar (26). At least one of the first connecting elements (24) is at least partly surrounded by a marking (36).
