Rigid Container for Biopharmaceutical Pouch with Movable Holding Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rigid containers for flexible 3D pouches with biopharmaceutical fluids face challenges in maintaining the integrity of the pouch and its contents during transportation, especially when partially filled, due to abrupt movements or significant accelerations, and lack compactness for efficient shipping.
Innovation Solution
A rigid container design featuring a containment wall with movable holding means that can be applied with axial force to the upper surface of the pouch, allowing for adjustable positioning and stiffening to maintain the pouch's integrity regardless of filling volume, combined with optional stiffening chambers or support elements for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid container with a containment wall and cylinder system is used to protect a flexible pouch during transportation, then the integrity of the pouch is improved, but the axial space requirement increases, reducing compactness
Solution Approach 1:
The holding means are designed to be movable or deformable between an inactive retracted state and an active expanded state, allowing the containment wall to be positioned at different locations along the axial direction. This dynamic adjustment enables the system to adapt to different pouch filling volumes while maintaining pouch integrity, thereby reducing the axial space requirement when the pouch is not completely filled.
Solution Approach 2:
The holding means can be applied at any desired location of a continuous zone of the inner surface of the side wall, enabling continuous adjustment of the containment wall position. This parameter change allows the system to optimize the axial space usage based on the actual pouch filling volume while maintaining sufficient protection during transportation.
2Adaptability or versatility
If the containment wall is designed to accommodate variable filling volumes, then the adaptability is improved, but the device complexity increases due to the need for movable holding means
Solution Approach 1:
The holding means utilize the flexibility of the pouch itself by applying to the inner surface of the side wall. This approach leverages the existing flexible structure of the pouch to achieve adaptability to different filling volumes without requiring complex rigid mechanical systems, thereby reducing device complexity while maintaining versatility.
Solution Approach 2:
The movable holding means are designed to work with the natural deformation and positioning of the flexible pouch. The pouch's own structure and material properties assist in the positioning and support of the containment wall, reducing the need for additional complex control mechanisms and simplifying the overall device design.

AI summary
The container includes a lower wall and an erect side wall limiting an upper opening of a housing for accommodating a flexible pouch containing a fluid; containment elements including a containment wall, the gap between its peripheral edge and the side wall being limited; the containment wall adapted to be applied against the pouch and held fixed in this position by holding elements arranged in the container and borne by the containment elements by a structural and functional combination, and being movable between an inactive retracted state and an active expanded state, in which a distal end part is either moved away from the side wall or applied there against without any chance of sliding; and adapted to be applied at any desired location of a zone of the side wall such that the containment wall can be applied and held against the pouch regardless of how full the latter is.
