Pharmaceutical Bag Gripping Member Duct Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gripping members for pharmaceutical product bags, with hinged flat jaws, face issues due to the longer infusion duct folding over the injection duct, causing interference with machine parts during movement, which prevents access to the injection duct.
Innovation Solution
A gripping member with two flat, rectangular jaws hinged by a vertical coupling pin, featuring an L-shaped jaw with an elastically deformable fin and specific slots to manage duct positioning, allowing the infusion duct to be folded down and preventing interference with machine parts while maintaining access to the injection duct.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the infusion duct is made longer to reach the required position, then the duct can reach the necessary length, but the duct may fold over the injection duct and interfere with machine parts
Solution Approach 1:
The patent introduces a movable folding section in the infusion duct that can dynamically change its configuration. The folding section includes a first section and a second section that can rotate relative to each other about a folding axis, allowing the duct to adapt its shape based on spatial constraints while maintaining necessary length.
Solution Approach 2:
The patent adds a rotational degree of freedom at the folding section, enabling the infusion duct to move from a linear configuration to a folded configuration by rotating the second section relative to the first section. This dimensional change allows the duct to navigate around the injection duct and avoid interference with machine parts.
2Strength
If the gripping member is designed to hold the bag securely, then the bag is firmly gripped, but the ducts may interfere with fixed parts of the machine during movement
Solution Approach 1:
The folding section of the infusion duct provides dynamic adaptability, allowing the duct to change its spatial configuration during machine operations. This ensures that even when the gripping member holds the bag firmly, the flexible folding section can adjust to avoid colliding with fixed machine parts during movement.
3Length of moving object
If the infusion duct is longer than the injection duct, then the infusion duct can reach the required position, but it may fold over the injection duct preventing access
Solution Approach 1:
The folding section enables the infusion duct to dynamically adjust its position and orientation. When needed, the folding section can be positioned to clear the injection duct, ensuring unobstructed access for injection operations, while still maintaining the necessary length to reach the infusion position.
Solution Approach 2:
By introducing the folding mechanism with rotational capability, the infusion duct can change its spatial arrangement to prevent overlapping with the injection duct. The folding section can rotate out of the way, providing clear access to the injection duct while maintaining the infusion duct's required length.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures the gripping member can securely hold the bag without duct interference, facilitating smooth operation within the automatic machine and maintaining access to both ducts, thus addressing the drawbacks of existing designs.

AI summary
A bag (2) for pharmaceutical products is gripped by a gripping member provided with two jaws (6, 7) movable between a gripping position and a releasing position of the bag (2), with a recess (19) obtained between the two jaws (6, 7) to accommodate therein at least one duct (4) to access the content of the bag (2), and with a support pin (20) protruding into the recess (19) to allow the access duct (4) to be folded from a substantially rectilinear, initial configuration to a final configuration, where the access duct (4) is folded about the support element (20) itself.
