Solution Overview
Problem
Current mobile water analysis systems cannot analyze multiple water samples simultaneously, leading to inefficiencies and potential errors due to the need for sequential analysis, which is time-consuming and may result in transient water quality changes being missed.
Innovation Solution
A sample device with upwardly open compartments separated by dividing walls, designed to accommodate multiple removable test elements from a mobile water analyzer, allowing for simultaneous analysis of multiple water samples, with optional compartments for detectors and adjustable configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If sequential analysis of water samples is performed using current mobile water analysis systems, then the analysis can be completed with existing single-sample devices, but the analysis time increases and transient water quality changes may be missed
Solution Approach 1:
The sample device is divided into multiple separate compartments (e.g., four compartments) that can simultaneously hold different water samples. Each compartment is isolated by dividing walls, allowing independent analysis of multiple samples at the same time, thereby reducing total analysis time and enabling detection of transient water quality changes that would be missed in sequential analysis.
2Productivity
If multiple water samples are analyzed simultaneously, then analysis efficiency and detection of transient changes improve, but the device complexity increases
Solution Approach 1:
The device uses simple vertical dividing walls to segment the sample chamber into multiple compartments. This segmentation approach achieves multi-sample capability while maintaining relatively simple device structure, as the dividing walls are basic structural elements that do not significantly increase overall device complexity.
Solution Approach 2:
The sample device is designed to work with existing mobile water analysis systems and removable test elements. The universal interface allows the enhanced multi-sample device to be compatible with current analyzers, maintaining ease of operation while improving productivity through simultaneous analysis of multiple samples.
3Productivity
If multiple samples are analyzed at once, then the throughput increases, but the risk of errors due to device complexity may increase
Solution Approach 1:
By physically separating samples into distinct compartments with dividing walls, the device eliminates cross-contamination between samples while maintaining simple operational procedures. Each compartment operates independently, reducing error propagation and maintaining high reliability even as throughput increases.
Solution Approach 2:
The device design allows samples to be independently processed in each compartment without requiring complex inter-compartment coordination. The simple structure enables users to easily load multiple samples and reagents, and the system automatically handles the analysis, reducing human error and improving reliability.
