Solution Overview
Problem
Conventional biological and chemical sampling devices in flowing aqueous media are ineffective in detecting materials present in low concentrations and fail to identify brief or localized changes in the composition of the aqueous medium between successive samples.
Innovation Solution
A sampling device with a rectilinear support structure, an accumulation interface, and a flotation means that allows the device to be positioned across the flow with a vertical orientation, incorporating a spongy accumulation interface for retention and a pinching mechanism for efficient sampling and wringing of materials, ensuring representative sampling of materials in suspension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If spot sampling is used in flowing water, then the sampling operation is simple, but the detection of materials at low concentrations is ineffective
Solution Approach 1:
The accumulation interface accumulates materials from the aqueous medium over time before sampling, performing the accumulation action in advance. This allows materials present in very small quantities to be concentrated on the interface, enabling their subsequent detection while maintaining operational simplicity.
Solution Approach 2:
The accumulation interface provides a localized region with special properties (spongy structure) that selectively retains materials from the flowing water. This local accumulation zone concentrates materials at low concentrations without requiring complex system-wide modifications.
2Ease of operation
If spot sampling at regular intervals is used, then the sampling process is straightforward, but brief or localized changes in composition are missed
Solution Approach 1:
The accumulation interface continuously accumulates materials from the flowing water as it passes through, rather than taking discrete snapshots. This continuous accumulation process ensures that brief or localized changes in composition are captured and retained on the interface, preventing information loss while maintaining operational simplicity.
3Device complexity
If the device is positioned horizontally with flow, then the structure is simple, but the accumulation interface does not effectively retain materials
Solution Approach 1:
The flotation means provides an upward buoyant force that counteracts the downward force of gravity on the accumulation interface. This positioning keeps the accumulation interface at the water surface or in the upper portion of the flow, where it can effectively retain materials through the combined effects of buoyancy and the spongy structure's capillary action.
