Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in accurately positioning connecting elements with high precision and control for joining devices, particularly in preventing uncontrolled or premature movement during transfer.
Innovation Solution
A device with a pivoting lever and adjustable end stop system that blocks and releases the movement of connecting elements, using a two-sided lever design with a blocking position and release position, and a feed device for precise transfer, along with optional spring elements and guide rails for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blocking device with a lever is used to prevent uncontrolled movement of connecting elements, then safety and control are improved, but the device complexity increases due to additional components
Solution Approach 1:
The patent combines the blocking function and the positioning function into a single lever mechanism. The lever serves dual purposes: it blocks the connecting element from moving prematurely and also positions it accurately in the transfer area, thereby reducing the need for separate blocking and positioning devices.
Solution Approach 2:
The lever is designed as a multi-functional component that performs multiple tasks: blocking movement, positioning the connecting element, and interacting with the feed device to enable controlled transfer. This multi-functionality reduces the overall number of components needed in the system.
2Manufacturing precision
If an end stop is added to prevent premature lever movement, then positioning precision is improved, but the device complexity increases
Solution Approach 1:
The end stop is positioned in advance to define the precise location where the lever should be blocked. This preliminary positioning ensures that the lever cannot move prematurely and maintains accurate positioning of the connecting element throughout the process.
Solution Approach 2:
The end stop acts as an intermediary element between the lever and the fixed structure, providing a precise stopping point that controls lever movement without requiring complex control mechanisms. It mediates the interaction to achieve accurate positioning.
3Adaptability or versatility
If a two-sided lever design is used with first and second arms, then functionality is improved for blocking and retaining, but the device complexity increases
Solution Approach 1:
The lever is segmented into two distinct arms: a first arm for blocking movement by interacting with the end stop, and a second arm for retaining the connecting element. This segmentation allows each arm to be optimized for its specific function while remaining part of a single integrated lever.
Solution Approach 2:
The two-sided lever design allows the lever to dynamically switch between different functional states. The first arm engages with the end stop for blocking, while the second arm engages with the connecting element for retaining, providing adaptable functionality through a single dynamic component.

AI summary
The invention relates to a device comprising a feed unit and a blocking unit (4) having a lever (40) that can be adjusted between a blocked position and a release position, and a method for positioning connection elements, wherein a connection element (2) can be transferred by means of the feed unit (3) from an acceptance region (I) into a handover region (II) for a joining unit, wherein in the blocking position the at least one lever (40) blocks a movement of the connection element (2) from the acceptance region (I) into the handover region (II) and releases same in the release position, and wherein by means of an end stop a movement of the lever (40) out of the blocking position into the release position can be blocked. The at least one lever (40) is designed as a two sided lever (40) comprising a first arm (41) and a second arm (42), wherein a first arm (41) of the at least one lever (40) cooperates with the at least one end stop to block a movement of the at least one lever (40) out of the blocking position into the release position and, in the blocked position, a second arm (42) of the at least one lever (40) acts as retaining jaws for the connection element (2). The invention further relates to a device for placement of connection elements.
