Rectangular Transfer Interface for Sterile Large-Object Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transfer systems with circular cross-sections in controlled environments limit the size of objects that can be transferred, require additional operations for larger items, and increase contamination risk due to unused space and attack surfaces.
Innovation Solution
Implementing non-circular, preferably rectangular, cross-sections for transfer interfaces that adapt to the shape of objects, allowing larger items to be transferred efficiently while reducing contamination risk through optimized space utilization and sealed intermediate areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If round cross-sections are used for transfer interfaces, then manufacturing is simpler and devices are more compact, but the size of objects that can be transferred is limited and additional operations are required for larger items
Solution Approach 1:
The transfer interface cross-section is changed from a symmetric circular shape to a non-symmetric rectangular shape. This asymmetric geometry allows objects with various dimensions to pass through without requiring multiple transfer operations, as the rectangular opening can accommodate objects that are too large for circular openings while maintaining a compact device structure.
2Reliability
If round cross-sections are used for transfer interfaces, then device structure is simpler, but unused space and attack surfaces increase contamination risk
Solution Approach 1:
The circular transfer interface is replaced with a rectangular cross-section that better utilizes the available space. This asymmetric shape eliminates unused corners and reduces the surface area that could potentially be contaminated, thereby improving reliability by reducing contamination risk while accepting slightly increased geometric complexity.
3Volume of moving object
If objects are centered horizontally through round transfer interfaces, then transfer is possible, but maximum dimensions are limited by the circular cross-section
Solution Approach 1:
The circular cross-section that requires precise horizontal centering is replaced with a rectangular cross-section. This asymmetric shape provides more forgiving alignment tolerances and allows objects with larger maximum dimensions to pass through without requiring exact centering, thereby increasing both object size capability and ease of operation.

AI summary
The invention generally proposes a transfer system for transferring at least one object with a feed device that is movable from a first controlled environment, in particular an autoclave, to a second controlled environment, in particular an isolator, via non-circular, in particular rectangular, transfer interfaces formed by the first and/or second controlled environment, wherein at least two transfer interfaces can be coupled to each other in such a way that an intermediate space and/or an intermediate area is formed between the transfer interfaces, wherein the object is transferred after decontamination and/or sterilization of the first and/or second controlled environment.
