Solution Overview
Problem
Current dialysis machines face issues with user-friendliness, temperature loss of dialysis fluid due to external hoses, and the risk of hose tangling or damage, as well as the use of unsuitable filter modules.
Innovation Solution
The dialysis machine integrates connection couplings for the dialyzer directly into the housing, eliminating the need for external hoses and providing a secure, tidy, and adaptable connection system that prevents the use of unsuitable filter modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external connecting hoses are used to connect the dialyzer to the dialysis machine, then the dialyzer can be detached and replaced, but temperature losses occur in the dialysis fluid and the hoses can become tangled or damaged
Solution Approach 1:
The patent merges the connection couplings directly into the housing of the dialysis machine, eliminating the need for external connecting hoses. The first and second connection couplings are integrated into the housing structure, allowing the dialyzer to connect directly to the fluid system without intermediate tubing, thus preventing temperature losses while maintaining dialyzer replaceability
Solution Approach 2:
The patent extracts the connecting hoses from the system by integrating the connection functions directly into the housing. The external hoses that previously connected the dialyzer to the machine are removed, and their connection functions are embedded into the housing structure itself, eliminating the source of temperature loss and tangling problems
2Adaptability or versatility
If external connecting hoses are used for dialysis fluid connection, then the system is flexible, but the hoses can be pinched or torn off by obstructions
Solution Approach 1:
The connection couplings are merged into the housing structure, creating a rigid, protected connection path for the dialysis fluid. The hoses are eliminated entirely, and the fluid connection is achieved through integrated couplings that cannot be pinched or torn off, thereby improving reliability while maintaining connection flexibility through the dialyzer's detachable design
3Ease of operation
If machine-external connecting hoses are used, then the fluid system can be accessed, but user-friendliness is reduced and the connection area becomes cluttered
Solution Approach 1:
The connection couplings are merged into the housing, creating a compact and organized connection area. The external hoses and their complex routing are eliminated, resulting in a cleaner, more user-friendly interface. The dialyzer connects directly to the housing-integrated couplings, simplifying the overall setup and reducing clutter in the connection area
4Adaptability or versatility
If any filter/dialyzer can be connected to the machine, then versatility is high, but unsuitable filter modules may be used
Solution Approach 1:
The patent employs asymmetric design in the connection couplings and dialyzer interface, where the geometric shape, positioning, or dimensional characteristics of the couplings are specifically configured to match only suitable dialyzer types. This asymmetric configuration prevents incompatible or unsuitable filter modules from being connected, ensuring reliability while maintaining versatility for appropriate dialyzer variants
