Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual sampling and laboratory examination methods are used for detecting analytes in water or wastewater, then measurement precision can be maintained, but time consumption and personnel effort increase significantly

Engineering Contradiction:
Improveanalyte detection accuracyVSAvoidsampling and analysis time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The sampling apparatus performs self-service by automatically concentrating and extracting analytes from sampled liquid directly in the field, eliminating the need for manual laboratory preparation. The system autonomously prepares samples for analysis, reducing both time consumption and personnel involvement while maintaining measurement precision through integrated concentration and extraction functions.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If manual laboratory examination methods are used for systematic monitoring of wastewater, then measurement precision is maintained, but productivity decreases due to high time and personnel requirements

Engineering Contradiction:
Improveanalyte determination accuracyVSAvoidmonitoring efficiency
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The apparatus autonomously performs sampling, concentration, and extraction operations, enabling systematic monitoring of multiple wastewater sources without proportionally increasing personnel requirements. This self-service capability significantly improves productivity by automating the entire sample preparation workflow while maintaining analytical precision.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary concentration and extraction of analytes directly at the sampling location before transport to the laboratory. This preliminary action reduces the workload at the laboratory stage, enabling faster processing of multiple samples and thereby improving overall monitoring productivity while preserving measurement accuracy.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If large volumes of liquid samples are transported to laboratories for analysis, then measurement precision can be ensured, but device complexity and transport requirements increase

Engineering Contradiction:
Improveanalyte analysis accuracyVSAvoidsampling apparatus complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The apparatus extracts only the necessary analytes from large volumes of liquid sample and concentrates them into small-volume preparations suitable for transport. This extraction function reduces transport requirements and simplifies logistics while maintaining measurement precision by providing concentrated analyte samples that require less handling and storage capacity.

Inventive Principle:
Principle #2Taking out (Extraction)

4Productivity

If automated sampling and concentration functions are integrated into the apparatus, then productivity improves, but device complexity increases

Engineering Contradiction:

Solution Approach 1:

The apparatus merges sampling, concentration, and extraction functions into a single integrated device. This combination improves productivity by automating multiple operations sequentially without requiring separate equipment for each function. While integration increases device complexity, it eliminates the need for multiple separate apparatuses and manual transfer steps, ultimately simplifying the overall workflow.

AI summary

An automatic sampling apparatus for taking liquid samples for the qualitative or quantitative determination of at least one analyte contained in the sample liquid includes a sample line that can be fluidically connected to the sampling station, a pump device, at least one sample container that can be fluidically connected to the sample line, and an electronic control system. The electronic control system is configured to fluidically connect the sample line to the sample container such that a fluid flow path extending from the sampling station through the sample line into the sample container is formed. The electronic control system is further configured to transport, using the pump device, a definable volume of the sample liquid, in the form of a liquid sample, along the fluid flow path into the sample container. The sampling apparatus is configured for concentrating or extracting the analyte present in the liquid sample.
