Solution Overview

Problem

Current methods for processing samples to detect microorganisms are laborious and time-consuming, lacking efficient devices for simultaneous processing of multiple samples, which complicates the removal of interfering materials and concentration of analytes.

Innovation Solution

An apparatus comprising a sample-receiving component with a filter element and a filtrate-receiving component with an analyte-capture element, allowing for the simultaneous processing and concentration of analytes from multiple samples in a single step, facilitated by a flow path that enables fluid passage and contact with the analyte-capture element, and optionally utilizing negative pressure for sample processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional pre-treatment methods are used to remove interfering material and concentrate analytes, then the detection accuracy is improved, but the processing time increases and labor requirements increase

Engineering Contradiction:
Improvedetection accuracyVSAvoidprocessing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The device merges the filtration function (removing interfering material) and the analyte capture function (concentrating target substances) into a single integrated unit. The filter element and analyte capture element are positioned in sequence within the same housing, allowing both functions to be performed simultaneously in one操作步骤, eliminating the need for separate filtration and concentration steps required by traditional methods

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The device performs multiple functions (filtration, concentration, and preparation for detection) within a single apparatus. The filter element removes interfering particles while the analyte capture element simultaneously concentrates the target analytes, creating a multi-functional device that replaces multiple separate pre-treatment operations

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If multiple samples are processed sequentially using traditional methods, then each sample receives adequate pre-treatment, but the total processing time increases significantly

Engineering Contradiction:
Improvepre-treatment qualityVSAvoidprocessing throughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The device is designed with multiple filter elements and analyte capture elements arranged in parallel within the same housing. Each sample can be directed to its own filter-analyte capture pair, allowing simultaneous processing of multiple samples while maintaining the same pre-treatment quality as single-sample processing. The segmented design enables parallel operation without compromising individual sample treatment

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If multiple pre-treatment steps are performed separately, then each step can be optimized, but the device complexity and operational difficulty increase

Engineering Contradiction:
Improveanalyte concentrationVSAvoidnumber of processing steps
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The device combines filtration and analyte capture into a single integrated flow path. The filtered liquid automatically flows from the filter element to the analyte capture element without requiring manual transfer or intermediate containers, reducing the number of operational steps while maintaining analyte concentration efficiency

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The device uses a through-flow design where the filtrate serves as the intermediary medium that automatically transports analytes from the filter element to the analyte capture element. This eliminates the need for manual handling and reduces operational complexity while ensuring complete transfer of concentrated analytes

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A first apparatus (100) for processing a liquid sample is disclosed. The apparatus (100) includes a sample-receiving (120), a filtrate-receiving component (150), and an analyte-capture element (170). The apparatus (100) forms a liquid flow path through which the sample passes, thereby causing the analyte-capture element (170) to capture an analyte, if present. A method is disclosed whereby a liquid sample is passed through the first (100) apparatus and the analyte-capture element (170) is easily separated from the apparatus for further processing and detection of the analyte. A structurally-related second apparatus (200) for processing a plurality of liquid samples, and a corresponding method of use, also is disclosed.
