Modular Microorganism Sampling Device for Ballast Water
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional microorganism sampling devices for ballast water are bulky, complex, and difficult to maintain due to integrated water supply and discharge pipes, which hinders cleaning and filter replacement operations.
Innovation Solution
A microorganism sampling device with a detachable head part and housing part, featuring a filter part with a tubular filter and cup, allowing for a simple and compact configuration, where the water supply and discharge channels are separate and can be connected externally, enabling easy maintenance and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water supply pipes and discharge pipes are integrally incorporated into the water storage container, then the device achieves a complete sampling system, but the device size and structural complexity are increased
Solution Approach 1:
The device is divided into separate functional modules: a water storage container, a filter unit with its own housing, and external pipe connections. The filter unit can be detached from the storage container, allowing each component to be optimized independently and reducing overall structural complexity while maintaining complete sampling functionality.
Solution Approach 2:
External pipes serve as intermediaries connecting the water storage container to the filter unit and discharge points. This eliminates the need for integral internal piping, reducing the complexity of the container structure while ensuring complete water flow path for sampling.
2Reliability
If water supply pipes and discharge pipes are integrally incorporated into the water storage container, then the sampling system is complete, but the maintainability is reduced
Solution Approach 1:
The filter unit is designed as a separate detachable module with its own housing, allowing it to be removed from the water storage container for easy cleaning and maintenance. The filter element itself can be accessed and replaced without disassembling the entire sampling system.
Solution Approach 2:
The filter element is extracted as a separate replaceable component within the filter unit housing. This allows the filter to be removed and cleaned or replaced independently, significantly improving maintainability while the filter unit remains connected to the sampling system.
3Reliability
If the device is designed with integrated components, then the sampling function is complete, but the device size is increased
Solution Approach 1:
The sampling device is segmented into a compact water storage container and a separate filter unit that can be positioned independently. This modular arrangement reduces the overall device volume compared to an integrated design, as components can be optimized for their specific functions without requiring additional space for internal connections and housing.

AI summary
A microorganism sampling device includes: a head part that has a water supply channel to which a water supply pipe for supplying sample water can be connected; a housing part to an upper part of which the head part can be detachably attached; a frame-structured tube; a tubular filter that is arranged within the tubular body; a cup that communicates with the tubular filter and is attached to one end of the tube body; and a cap that has a channel communicating with the tubular filter and is attached to the other end of the tube body. The microorganism sampling device further includes a filter part housed in the housing part, in which a bottom part of the cup is supported by a bottom part of the housing part. The head part is attached to an upper part of the housing part.
