Biopharmaceutical Bag Housing With Inner Shell Lateral Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective cases for biopharmaceutical liquid bags suffer from inadequate lateral support, excessive pressure on the bags, complex assembly, and delicate structures, leading to potential damage and assembly challenges.
Innovation Solution
A protective case design featuring a lower shell with side walls and an upper shell that inserts into the lower shell, providing lateral support through the upper shell's housing, simplified assembly, and reduced longitudinal movement, with features like baffles and fasteners to secure the bag and tubes, using plastic materials for biocompatibility and stress distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two shells are assembled one on the other to enclose the biopharmaceutical liquid bag, then the bag is protected from external attacks and shocks, but the lateral support is insufficient and excessive pressure is exerted on the bag
Solution Approach 1:
The protective casing is divided into three distinct functional elements: an outer shell providing structural protection, an inner shell providing lateral support, and a central bag containing the biopharmaceutical liquid. This segmentation allows each element to perform its specific function independently, with the inner shell specifically designed to provide lateral support without exerting excessive pressure on the bag.
Solution Approach 2:
The inner shell acts as an intermediary element between the outer shell and the biopharmaceutical liquid bag. It receives the protective function from the outer shell and translates it into appropriate lateral support for the bag, filtering out excessive pressures while maintaining necessary protection.
2Reliability
If two shells are assembled one on the other to enclose the biopharmaceutical liquid bag, then protection is provided, but the assembly requires exact and precise superposition of the two shells
Solution Approach 1:
By segmenting the protective structure into distinct outer and inner shells with specific functions, the design simplifies the assembly process. Each shell can be assembled independently with standard fastening mechanisms, eliminating the need for precise superposition of complex multi-component structures.
Solution Approach 2:
The inner shell is specifically designed with localized lateral support features that provide protection where needed without requiring precise alignment of complex assembly components. This localized approach simplifies the overall assembly requirements while maintaining effective protection.
3Ease of operation
If elastic plastic films are fixed on shells to enclose the biopharmaceutical liquid pockets, then the pockets are held in place, but the structure becomes complex and delicate
Solution Approach 1:
The elastic plastic films are extracted from the protective casing structure and replaced by the rigid inner shell that provides lateral support. This eliminates the need for complex film fixation mechanisms while maintaining the holding function through the structural support of the inner shell.
Solution Approach 2:
The inner shell is designed as a flexible structural element that can adapt to the bag's shape while providing consistent lateral support. This flexible rigid structure replaces the complex system of elastic films and fixation mechanisms, simplifying the overall structure while maintaining functionality.
