Alkalizing Container Adapter for Fixed Extracorporeal Receptacles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insert containers for extracorporeal blood treatment machines, such as bicarbonate cartridges, have a small volume requiring frequent replacement and generate significant plastic waste due to their single-use nature, leading to inefficiencies and environmental impact.
Innovation Solution
A container arrangement with an adapter that fits into the existing insert container receptacle of a blood treatment machine, allowing larger containers with more alkalizing dry substance to be used, reducing the need for frequent replacements and minimizing plastic waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional small-volume insert containers are used, then the container fits the predetermined receptacle topology, but frequent replacement is required and plastic waste increases
Solution Approach 1:
The system is divided into three segments: the existing receptacle, the adapter (which interfaces with the receptacle), and the larger container (which interfaces with the adapter). This segmentation allows the container size to be decoupled from the receptacle constraints, enabling larger containers to be used without modifying the original receptacle design.
Solution Approach 2:
The adapter serves as an intermediary component between the receptacle and the larger container. It translates the connection topology requirements, allowing a container with different dimensions and topology to interface with the original receptacle through the adapter's mediation.
2Reliability
If conventional small-volume insert containers are used, then single-use safety is ensured, but environmental impact increases due to plastic waste
Solution Approach 1:
By separating the adapter (which remains in the machine) from the container (which is replaced), the system allows the container material to be reduced or changed while maintaining the safety and reliability functions in the adapter portion.
Solution Approach 2:
The adapter is retained and reused in the machine, while only the container is replaced. This reduces the frequency of replacing machine-mounted components and decreases overall waste, as the durable adapter remains in place while containers can be optimized for different materials or refilled.
3Ease of operation
If larger containers with more alkalizing dry substance are used, then operational effort is reduced, but compatibility with the predetermined receptacle topology becomes problematic
Solution Approach 1:
The adapter acts as a topology translator, allowing containers with different connection topologies to interface with the predetermined receptacle. This enables the use of larger, more operationally efficient containers without being constrained by the original receptacle's topology requirements.
Solution Approach 2:
The adapter provides universal interface capability, allowing different container types and sizes to be used with the same receptacle system. This multi-functionality enables the system to accommodate larger containers that reduce operational effort while maintaining compatibility through the adapter's standardized interface.
