Angled Receiving Port for Sterile Object Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing receiving ports with narrow passage cross-sections often cause small objects to fall and become contaminated during transfer, compromising sterility in sterile environments.
Innovation Solution
A receiving port design featuring a tube-like feed-through device with a feed-through axis angled relative to the passage axis, creating an apparent larger cross-section through deformation of the passage and feed-through contours, which supports gravity-assisted transfer and prevents objects from falling, using a feed-through collar to ensure reliable insertion and a pivotable joint for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a narrow passage cross-section is used in the receiving port, then the port structure remains compact and simple, but small objects fall next to the port and become contaminated, compromising sterility
Solution Approach 1:
The feed-through device is arranged at an angle to the passage axis, creating an apparent feed-through cross-section that is larger than the real feed-through cross-section. This angular arrangement effectively increases the passage area in the critical dimension while maintaining a compact structure, preventing objects from falling outside the port and ensuring sterility.
Solution Approach 2:
The tube-like feed-through device acts as an intermediary element between the passage opening and the container. It guides objects through the port at an angle, ensuring they remain within the controlled sterile path and preventing contamination, thus resolving the contradiction between maintaining sterility and managing passage area.
2Productivity
If the feed-through axis is arranged at an angle to the passage axis to maximize apparent feed-through cross-section, then transfer efficiency improves, but the device complexity increases
Solution Approach 1:
By arranging the feed-through device at an angle to the passage axis, the invention creates an apparent feed-through cross-section that is larger than the real cross-section. This angular arrangement maximizes the effective transfer area without requiring a proportionally larger physical structure, thereby improving transfer efficiency while controlling device complexity.
3Productivity
If the passage contour and feed-through contour are deformed in a shape-analogous manner, then the apparent feed-through cross-section is maximized, but manufacturing precision requirements increase
Solution Approach 1:
The invention deforms the passage contour and feed-through contour in a shape-analogous manner to maximize the apparent feed-through cross-section. By coordinating the deformation of both contours, the design achieves optimized transfer geometry while managing manufacturing precision requirements through systematic contour transformation rather than arbitrary shaping.

AI summary
A receiving port includes a passage opening arranged within a port contour, and a tube-like feed-through device. The passage opening includes a passage plane and a real passage cross-section, each being arranged orthogonally to a passage axis. The tube-like feed-through device is associated with the passage opening and includes a feed-through axis along which the objects are guided, and a real feed-through cross-section arranged orthogonally to the feed-through axis. The feed-through axis is arranged at an angle to the passage axis so that gravity guides the objects and so that an apparent feed-through cross-section results for the tube-like feed-through device. A passage contour and/or a feed-through contour of the real passage cross-section are formed from a respective basic contour which corresponds to the port contour of the receiving port, deformed in a shape-analogous manner to one another so that the maximized apparent feed-through cross-section is formed.
