Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sampling devices cannot remove fluid samples cumulatively over time while simultaneously filtering them, and they lack 'smart' sampling capabilities to control individual sample vessels automatically.
Innovation Solution
An intermediate memory dosing unit with a container having an inlet and a two-way outlet, featuring a riser tube as the first outlet for sample collection and an outflow as the second outlet for excess fluid disposal, along with a filter unit to improve sample quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional sampling devices are used, then sampling can be performed, but samples cannot be taken cumulatively over time and simultaneously subjected to filtration
Solution Approach 1:
The device is segmented into distinct functional components: a sample collection container for cumulative sampling, a separate filter unit with filter medium, and a dosing mechanism. This segmentation allows each component to perform its specific function independently, enabling cumulative sampling with filtration capability while maintaining manageable device complexity.
Solution Approach 2:
The filter unit acts as an intermediary between the sample collection container and the dosing mechanism. It temporarily holds and filters the accumulated sample before dosing, enabling the system to separate the cumulative sampling function from the filtration function while still achieving both simultaneously.
2Extent of automation
If conventional sampling devices are used, then sampling can be performed, but they lack smart sampling capabilities to control individual sample vessels automatically
Solution Approach 1:
The device incorporates a control unit that receives feedback signals (such as fill level indicators or timing signals) and automatically adjusts the dosing process accordingly. This feedback mechanism enables smart sampling capabilities where individual sample vessels can be controlled automatically based on real-time system state, achieving high automation without requiring overly complex control systems.
3Reliability
If samples are taken without filtration, then sampling is simple, but sample quality is reduced due to contamination by floating matter, sediment, or particles
Solution Approach 1:
The filter unit with filter medium serves as an intermediary component that improves sample quality by removing contaminants. It is integrated into the dosing path but separated from the cumulative sample collection, allowing filtration to be applied only when samples are dosed, thus improving reliability while minimizing the complexity impact of the filtration system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the collection of high-quality samples that are representative and reproducible, allowing for improved analysis by preventing contamination and retaining geo-chemical properties of the fluid, while also enabling automatic and controlled sampling processes.
Implementation Method 1
the fluid undergoes filtration on its way between the inlet and outlet
Implementation Method 2
a fluid can be guided from the inlet to the outlet solely by gravity (in the case of liquids)

AI summary
The invention relates to an intermediate storage and dosing unit for taking samples of a fluid. The intermediate storage and dosing unit comprises a container with an inlet and a two-way outlet. The two-way outlet has a riser pipe as a first outlet and a drain as a second outlet. The invention further relates to a system and a method for taking samples of a fluid, preferably water. The system particularly comprises a sampling unit and at least one sample container, wherein the sampling unit is configured to provide a fluid and the at least one sample container is configured to receive and store a fluid. Fluid transfer is also possible between the sampling unit and the at least one sample container. The intermediate storage and dosing unit of the type mentioned above is interposed between the sampling unit and the at least one sample container.
