Integrated Pump Housing Layout for Medical Washer Fluid Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning and disinfection machines face challenges with complex and prone-to-failure fluid supply systems, leading to increased water consumption, potential leaks, and operational safety risks due to external supply lines and branched water paths.
Innovation Solution
The design integrates the collecting pot and pump housing as a single component, with a 90° rotation of the circulation pump to align with the spray arms, reducing the need for external supply lines and optimizing water flow, using a central supply pipe within the washing chamber and a valve device for fluid separation during drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external supply lines are used to supply rinsing liquor to the spray device, then the spray device can be supplied with rinsing liquor, but the system becomes more complex and prone to leaks
Solution Approach 1:
The circulation pump is integrated directly into the collecting pot, eliminating the need for external supply lines. The pump housing forms a unified structure with the collecting pot, creating a compact fluid circulation system that reduces leak points and simplifies the overall device architecture.
2Loss of substance
If supply lines are routed outside the washing compartment, then the washing space is maximized, but water consumption increases due to flow losses
Solution Approach 1:
The circulation pump and collecting pot are merged into a single integrated unit, allowing supply lines to be routed internally through the pump housing rather than externally. This eliminates unnecessary flow path length and deflections, reducing water loss while maintaining washing space efficiency.
3Productivity
If multiple spray arms are arranged one above the other, then the spray device can effectively clean items, but the fluid supply system becomes more complex
Solution Approach 1:
The integrated circulation pump serving the collecting pot functions as a central hub that supplies multiple spray arms arranged vertically. The single pump unit provides universal fluid supply to all spray arms through internal routing, eliminating the need for separate supply lines for each spray arm level.
4Device complexity
If the circulation pump is positioned away from the collecting pot, then the pump can operate independently, but the system requires more components and connections
Solution Approach 1:
The circulation pump is positioned within the collecting pot structure, with the pump housing forming an integral part of the pot assembly. This merging reduces the number of separate components and connections, thereby simplifying the system while improving reliability by eliminating potential failure points at connection interfaces.
