Solution Overview
Problem
Conventional dialysis systems face inefficiencies in dissolving solid concentrates, such as sodium bicarbonate, due to the formation of a thick solution layer over the concentrate, which limits agitation and prevents complete dissolution, leading to waste and prolonged treatment times.
Innovation Solution
Maintaining a layer of solution over the solid concentrate at a depth of 0.5 to 1.5 inches ensures adequate agitation and dissolution, while preventing air from being pumped during treatment, thereby improving the utilization of the concentrate and reducing treatment duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a thick layer of solution is maintained over the solid concentrate to prevent air pumping, then air pumping is prevented, but agitation and dissolution of the solid concentrate are limited
Solution Approach 1:
The system dynamically adjusts the solution layer depth during treatment, maintaining it within the optimal range of 0.5 to 1.5 inches. This dynamic control allows the system to prevent air pumping while simultaneously ensuring adequate agitation and dissolution of the solid concentrate, resolving the contradiction between reliability and productivity.
Solution Approach 2:
The invention changes the critical parameter of solution layer depth from a conventional thick layer to a controlled shallow layer (0.5 to 1.5 inches). This parameter change enables both prevention of air pumping and maintenance of adequate agitation, as the shallow layer allows liquid introduction to effectively agitate the concentrate while still providing sufficient coverage.
2Reliability
If excess liquid is added to the container to prevent air pumping, then air pumping is prevented, but the dissolution of solid concentrate decreases due to reduced agitation
Solution Approach 1:
The system dynamically controls the solution layer depth to remain within 0.5 to 1.5 inches throughout the treatment. This dynamic adjustment ensures that enough liquid is present to prevent air pumping while maintaining sufficient agitation to maximize dissolve of the solid concentrate, thereby reducing waste.
Solution Approach 2:
The invention optimizes the solution layer depth parameter to a specific range (0.5 to 1.5 inches) that balances two competing requirements: preventing air pumping and maximizing agitation. This optimized parameter setting reduces both air pumping incidents and concentrate waste simultaneously.
3Productivity
If a shallow layer of solution is used to enhance agitation and dissolution, then dissolution of solid concentrate is improved, but air may be pumped from the container
Solution Approach 1:
The invention identifies and implements an optimal parameter range for solution layer depth (0.5 to 1.5 inches) that resolves the contradiction between agitation effectiveness and air pumping prevention. This specific depth range provides sufficient coverage to prevent air pumping while maintaining shallow enough depth to allow effective agitation of the solid concentrate.
4Reliability
If conventional methods are used with thick solution layers, then air pumping is prevented, but treatment duration is prolonged due to incomplete dissolution
Solution Approach 1:
The system implements dynamic control of solution layer depth throughout the treatment process, maintaining it within the optimal 0.5 to 1.5 inch range. This ensures continuous effective agitation for complete dissolve of the solid concentrate while preventing air pumping, thereby reducing treatment duration without sacrificing reliability.
