Pharmaceutical Bag Gripping Member with Nested Duct Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gripping members for pharmaceutical product bags, with protruding injection and infusion ducts, face issues where the longer infusion duct can fold over the injection duct, obstructing access and interfering with machine components during movement.
Innovation Solution
A gripping member with two flat, hinged jaws and an elastically deformable fin, featuring a locking mechanism and strategically positioned slots and pins, allows the infusion duct to be folded within the member, preventing interference with machine parts and ensuring access to the injection duct.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the infusion duct is made longer to ensure proper connection, then the infusion function is improved, but the duct may fold over the injection duct and interfere with machine parts during movement
Solution Approach 1:
The injection duct is positioned within the chamber formed by the two jaws, effectively nesting it inside the structure. This prevents the infusion duct from folding over it and eliminates interference with machine parts during gripping movements.
Solution Approach 2:
The ducts are arranged in a vertical configuration within the gripping chamber, utilizing the vertical dimension to prevent folding and interference. The injection duct is positioned below the infusion duct, creating a layered arrangement that avoids conflict during movement.
2Ease of operation
If the ducts are positioned to protrude upwards from the jaws, then access to the ducts is improved, but the longer infusion duct may fold over the injection duct
Solution Approach 1:
The injection duct is nested within the chamber defined by the jaws, positioning it below the infusion duct. This nested arrangement maintains accessibility while preventing the infusion duct from folding over the injection duct.
Solution Approach 2:
The ducts are pre-positioned in their final configuration during the gripping operation, with the injection duct already nested within the chamber before the gripping member closes. This preliminary positioning prevents folding during subsequent operations.
3Device complexity
If the gripping member uses a simple hinged jaw structure, then manufacturing complexity is reduced, but the duct arrangement may cause interference with machine parts
Solution Approach 1:
The injection duct is nested within the chamber formed by the simple hinged jaw structure. This nesting arrangement eliminates mechanical interference with machine parts while maintaining the simplicity of the gripping member design.
Solution Approach 2:
The ducts are arranged vertically within the gripping chamber, utilizing the vertical dimension to prevent interference with horizontally moving machine parts. This spatial arrangement resolves the conflict between simple structure and mechanical compatibility.

AI summary
A bag for pharmaceutical products is gripped by a gripping member provided with two jaws movable between a gripping position and a releasing position of the bag, with a recess obtained between the two jaws to accommodate therein at least one duct to access the content of the bag, and with a support pin protruding into the recess to allow the access duct to be folded from a substantially rectilinear, initial configuration to a final configuration, where the access duct is folded about the support element itself.
