Transfer Flange Release Lug to Prevent Door-Eyelet Jamming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transfer devices for objects from containers to cells face issues where objects can get trapped between inner and outer eyelets, preventing the cell door from closing properly, especially when the objects are near the hinge axis.
Innovation Solution
A stub end with a release lug is integrated into the device, positioned between the inner eyelets of the container flange, which prevents objects from becoming immobile during transfer by guiding them away from the eyelet area, ensuring the cell door can close securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If objects are transferred through the eyelet region during the transfer process, then the transfer function is achieved, but objects may become trapped between inner and outer eyelets, preventing door closure
Solution Approach 1:
The release lug is extracted as a separate functional element from the stub end, specifically designed to interact with objects in the eyelet region. This extracted component actively removes the harmful effect of trapped objects by pushing them out of the way, thereby resolving the contradiction between maintaining transfer efficiency and ensuring reliable door closure.
Solution Approach 2:
The release lug acts as an intermediary element between the stub end and the objects being transferred. It mediates the interaction by providing a controlled mechanism to displace objects that might otherwise become trapped, enabling both continuous transfer and reliable door closure without direct conflict between these functions.
2Productivity
If the stub end remains in the guide position to channel objects, then object flow is maintained, but the cell door cannot close due to obstruction by trapped objects
Solution Approach 1:
The release lug performs a preliminary action by proactively pushing objects out of the eyelet region before the door closure operation begins. This preliminary displacement prevents potential obstructions, ensuring that when the door closure is attempted, the path is clear and operation is easy, thus resolving the contradiction between maintaining object flow and enabling easy door closure.
Solution Approach 2:
The system dynamically transitions between two states: during object transfer, the stub end remains in the guide position with the release lug actively managing objects; before door closure, the release lug clears the path. This dynamic adaptation allows the system to optimize for object flow during transfer and ease of operation during closure, resolving the contradiction between these two operational requirements.

AI summary
A device for the tight transfer of objects from a container towards a cell, comprising: a cell flange intended to be fastened to a cell wall, and a container flange intended to equip the container, these two flanges being provided with a coupling; the cell flange being equipped with a hinge carrying a cell door; the container flange having a container door, with a bayonet connection to block this door, this connection including inner eyelets; connection for securing the container door to the cell door; the cell flange being equipped with a stub end movable between a guide position partially fitted into the central opening, and a clear position remote from the central opening. The stub end includes a lug fitting between two eyelets of the container flange in the guide position.
