Powder Storage Package with Immobilizing Walls for Dialysis Solutions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for preparing dialysis solutions from powdery materials face challenges such as instability, incompatibility of components, and logistical issues related to storage and transportation, leading to inconsistent solutions and increased risk of contamination.
Innovation Solution
A package design that stores powdery material in a single compartment with distinct sets of compositions, immobilized by opposing wall portions, allowing for controlled mixing with a solvent within the compartment to form a medical solution, while preventing significant mixing or migration during storage and transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If powdery materials are stored separately to maintain stability, then component stability is improved, but device complexity and preparation difficulty increase
Solution Approach 1:
The package divides the powdery material into multiple distinct sets (first set and second set) with different compositions, each stored in separate locations within the single compartment. This segmentation maintains component stability by preventing premature interaction while allowing all components to be housed in one package rather than multiple separate packages.
Solution Approach 2:
Multiple distinct sets of powdery material are nested within a single compartment structure, with each set positioned in specific locations. The opposing wall portions engage with these nested sets to immobilize them, creating a compact integrated package that replaces what would traditionally require multiple separate containers.
2Loss of time
If powdery materials are mixed immediately, then preparation time is reduced, but solution quality consistency deteriorates due to incompatibility
Solution Approach 1:
The package is pre-configured with distinct sets of powdery material in predetermined locations before use. The opposing wall portions are pre-positioned to engage with these sets, immobilizing them during storage and transport. This preliminary arrangement ensures that when preparation occurs, the materials are already in the correct positions for controlled mixing, reducing preparation time while maintaining solution quality consistency.
3Stability of the object's composition
If multiple compartments are used to store incompatible components, then component stability is improved, but manufacturing cost and material usage increase
Solution Approach 1:
The package segments incompatible powdery materials into distinct sets stored in different locations within a single compartment, eliminating the need for multiple separate compartments. This segmentation maintains component stability through spatial separation while reducing manufacturing complexity and cost by using one integrated structure instead of multiple compartments that would require additional seals, welds, and assembly steps.

AI summary
A package has a transport/storage state for storing powdery material which is to be mixed with a solvent to form a medical solution, e.g. for use in dialysis treatment. The package comprises a compartment (6) which is at least partially defined by two opposing wall portions, and a connector (10). In the transport/storage state, the compartment contains the powdery material in the form of at least two distinct sets (2A-2D) of powdery material of different compositions, where the opposing wall portions are brought into engagement with the powdery material so as to immobilize the sets of powdery material (2A-2D). When used for preparation of the medical solution, a fluid is selectively admitted into the package via the connector (10) so as to expand the compartment (6) and enable mixing of the sets (2A-2D) of powdery material with the solvent in the compartment (6).
