Solution Overview
Problem
The existing systems for filling and emptying dialysis machines require a high installation effort and are inflexible, making them unsuitable for small dialysis centers, as the devices for producing dialysis fluid are stationary and require moving the machines for filling and emptying.
Innovation Solution
A mobile device that combines a liquid container, a concentrate receptacle, and a preparation unit, allowing for on-site mixing and delivery of dialysis fluid to or from dialysis machines, with connections for filling, emptying, and cleaning, reducing the need to move machines for these processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stationary system with separate water tank and dialysis fluid production unit is used, then dialysis fluid can be produced and stored, but high installation effort and inflexibility result
Solution Approach 1:
The patent combines the water tank, dialysis fluid production unit, and dialysis machine into a single integrated mobile device. The water tank (15) and preparation unit (3) are merged with the dialysis machine functions, eliminating the need for separate stationary installations. This integration reduces installation effort while maintaining reliable dialysis fluid production capability.
Solution Approach 2:
The mobile device performs multiple functions: it stores water (15), produces dialysis fluid through mixing (3), stores concentrates (25), fills dialysis machines (1, 26), and even disinfects them. This multi-functionality replaces the need for separate stationary systems for water storage, fluid preparation, and machine maintenance, reducing overall installation complexity.
2Reliability
If stationary devices for producing dialysis fluid are used, then fluid production is reliable, but the system lacks flexibility and requires moving machines for filling
Solution Approach 1:
The device transitions from a stationary configuration to a mobile one, allowing the dialysis machine to remain in place while the fluid production and filling operations move to the machine. The mobile device can be positioned at the dialysis machine location, enabling flexible filling operations without requiring machine relocation.
Solution Approach 2:
The mobile device acts as an intermediary between the water source and the dialysis machine. It brings the fluid production capability directly to the machine location, serving as a mobile intermediary that eliminates the need for stationary infrastructure and machine movement.
3Adaptability or versatility
If a mobile device combining liquid container, concentrate receptacle, and preparation unit is used, then flexibility and mobility are improved, but device complexity increases
Solution Approach 1:
The patent merges the liquid container (15), concentrate receptacle (25), and preparation unit (3) into a single integrated mobile device. This combination consolidates multiple functions into one unit, improving mobility while managing complexity through integration rather than separate components.
Solution Approach 2:
The mobile device is designed as a universal unit that performs water storage, concentrate storage, fluid mixing, machine filling, and disinfection. This multi-functionality reduces the need for multiple separate devices, thereby improving mobility while actually reducing overall system complexity.

AI summary
The device (100) has a fluid container (15) for accommodating fluid i.e. reverse osmosis water, and a concentrate retainer (3) for accommodating concentrate. A concentrate connection is provided for addition of another container containing the concentrate and a preparation unit. The preparation unit is arranged and designed in such a manner that the fluid from the fluid container is mixed with the concentrate from the retainer and/or from the latter container containing the concentrate, in the preparation unit. An independent claim is also included for a method for filling a dialysis machine with a dialysis fluid and for discharging the dialysis fluid from the dialysis machine.
