Sterile Packaging Removal Device with Segmented Slit and Holding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for removing sterile objects from packaging often malfunction due to the residual bag interfering with the suction process, leading to incomplete removal and the need for separate disposal of packaging parts, which compromises sterility and efficiency.
Innovation Solution
A device comprising a clamping device, cutting device, holding device, and removal device that creates a single slit in the packaging, allowing secure and sterile removal of objects while maintaining the packaging in one piece for easy disposal, using rollers and suction elements to manage the packaging effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the foil packaging is completely cut off into two parts (cut-off part and residual bag), then the sterile object can be accessed, but the residual bag interferes with the suction device and prevents complete removal of the transport container
Solution Approach 1:
The packaging is divided into two parts: a first partial area that is completely cut off to provide access, and a second partial area (residual bag) that is intentionally left attached to the transport container. This segmentation allows the cutting device to create an opening while the holding device maintains attachment of the residual bag, preventing interference with the suction device during removal.
Solution Approach 2:
The holding device acts as an intermediary between the residual bag and the suction device. By holding the second partial area of the packaging, it prevents the residual bag from settling between the suction device and the transport container, ensuring direct contact and reliable removal.
2Ease of operation
If the foil packaging is completely cut off into two parts, then the sterile object can be accessed, but both parts must be disposed of separately increasing disposal complexity
Solution Approach 1:
The packaging is divided into two parts: a first partial area that is completely cut off to provide access, and a second partial area (residual bag) that is intentionally left attached to the transport container. This segmentation allows the cutting device to create an opening while the holding device maintains attachment of the residual bag, preventing interference with the suction device during removal.
3Productivity
If a suction device is used to remove the transport container, but part of the residual bag settles between the suction device and the transport container, then the suction device attacks the residual bag instead of the transport container
Solution Approach 1:
The holding device acts as an intermediary between the residual bag and the suction device. By holding the second partial area of the packaging, it prevents the residual bag from settling between the suction device and the transport container, ensuring direct contact and reliable removal.
Solution Approach 2:
The holding device is positioned and activated before the suction device attempts to remove the transport container. This preliminary action ensures that the residual bag is already secured and cannot interfere with the subsequent removal operation, preventing malfunction before it occurs.
