Press Collar Drive Unit With Visual Connection Alignment Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive units for press collars require manual alignment of connecting bolts, which can lead to errors, potential damage, and safety risks due to incomplete connections and visual obscurity.
Innovation Solution
The drive unit incorporates marked connecting elements that ensure a safe connection by providing visual indicators, ensuring the correct fit of connecting elements through markings that are covered only when the connection is complete.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual alignment of connecting bolts is used, then the device complexity is reduced, but the reliability and safety of connection deteriorates due to potential errors and incomplete connections
Solution Approach 1:
The patent applies visual markings (color-coded indicators) on the connecting elements to provide clear visual feedback about connection status. The markings change appearance or position to indicate whether the connecting bolt is properly aligned and fully inserted, eliminating the need for complex mechanical verification mechanisms while ensuring reliable connection.
Solution Approach 2:
The patent incorporates visual feedback mechanisms through markings that immediately indicate to the operator whether the connecting bolt is correctly positioned and fully inserted. This real-time visual feedback ensures proper connection without requiring complex mechanical interlocks or verification systems.
2Strength
If the connecting bolt is fully inserted into the recess, then the connection strength is improved, but the ease of operation deteriorates because the user cannot visually verify the correct fit
Solution Approach 1:
The patent uses visual markings that are obscured or changed when the connecting bolt is fully inserted into the recess. This allows the user to easily verify connection status at a glance - when the marking is visible, the connection is incomplete; when the marking is obscured, the connection is proper. This maintains strong connections while dramatically improving ease of verification.
Solution Approach 2:
Instead of providing visual verification when the connection is incomplete (the obvious state), the patent inverts the approach by providing visual verification when the connection is complete. The marking is designed to be obscured by the press collar element only when the connecting bolt is fully inserted, thus verifying proper connection through the absence of visibility rather than presence.
3Ease of operation
If the connecting bolt is not fully inserted, then the ease of operation is improved as the user can easily adjust position, but the reliability deteriorates causing potential damage to the jaw and risk of injury
Solution Approach 1:
The visual marking provides immediate feedback about connection status, allowing the user to easily adjust the connecting bolt position while ensuring that adjustments are made only when the marking indicates incomplete connection. This maintains operational flexibility while preventing dangerous incomplete connections from being used.
Solution Approach 2:
The patent requires the user to verify the marking before operating the press collar, ensuring that the connecting bolt is fully inserted before any pressing operation. This preliminary verification step prevents damage and injury while maintaining ease of adjustment during the connection process itself.

AI summary
The present invention relates to a drive unit for use with a press collar for pressing two workpieces, including a drive and pressing pliers connected to the drive, the pressing pliers having two jaws. In one embodiment, the jaws of the pressing pliers can be moved toward each other via the drive in order to close the press collar and to press the two workpieces. Furthermore, the two jaws each have a first connecting element for connecting to a second connecting element of the press collar. At least one of the first connecting elements is at least partly surrounded by a marking.
