Solution Overview

Problem

Existing methods for detecting transparent exopolymer particles (TEP) in water samples are inefficient and non-selective, making it difficult to rapidly and reliably quantify them, especially in industrial settings where rapid response is required.

Innovation Solution

A method involving the use of a fluorochromatic reagent specific to vicinal hydroxide groups, such as boronic acid derivatives, which changes fluorescence signal upon interaction with TEP, allowing for rapid and selective detection of TEP levels in water samples.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the colorimetric method with Alcian Blue dye is used to detect TEP, then TEP can be detected, but the detection process is slow and requires multiple steps (filtering, staining, washing, soaking, and colorimetric determination)

Engineering Contradiction:
ImproveTEP detection capabilityVSAvoiddetection speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent replaces the mechanical and chemical multi-step colorimetric detection system with a fluorescence-based detection system. The fluorochromatic reagent binds to TEP and produces a fluorescence signal that can be detected rapidly without requiring filtering, washing, or prolonged soaking steps, thus maintaining detection capability while dramatically improving detection speed.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the detection parameter from colorimetric measurement to fluorescence measurement. By using a fluorochromatic reagent that emits fluorescence when bound to TEP, the method achieves both high sensitivity and rapid detection, eliminating the time-consuming steps required by the colorimetric method.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If the Alcian Blue dye is used to detect TEP, then TEP can be detected, but the method is non-selective and anionic polymers or impurities interfere with the determination

Engineering Contradiction:
ImproveTEP detection capabilityVSAvoiddetection selectivity
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent introduces a fluorochromatic reagent as a selective intermediary that specifically binds to TEP through vicinal hydroxide groups. This reagent acts as a mediator between the detection system and TEP, providing high selectivity by only binding to the specific chemical structure of TEP and not to interfering substances like anionic polymers or impurities.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies the principle of local quality by designing a fluorochromatic reagent with specific chemical properties (fluorochromatic groups that bind to vicinal hydroxide groups) that are locally targeted to TEP structures. This localized chemical specificity ensures that only TEP is detected while other substances are ignored, thereby improving selectivity.

Inventive Principle:
Principle #3Local quality

3Measurement precision

If traditional detection methods are used, then TEP can be detected, but the operational efficiency in water-intensive processes cannot be improved due to the complexity and time requirements of the detection process

Engineering Contradiction:
ImproveTEP quantification capabilityVSAvoidoperational efficiency
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces the complex mechanical操作流程 of traditional detection (filtering, staining, washing, soaking) with a simplified fluorescence detection process. The fluorochromatic reagent method requires only mixing the reagent with the water sample and measuring the fluorescence signal, dramatically improving ease of operation and operational efficiency in water-intensive processes.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Method for detecting transparent exopolymer particles in a water sample. The method comprises step of obtaining a water sample and introducing a fluorochromatic reagent to the water sample. The fluorochromatic reagent is specific to vicinal hydroxide groups of transparent exopolymer particles, whereby the fluorescence signal of the reagent changes when it comes into contact with transparent exopolymer particles, i.e. TEP. Finally the fluorescence signal from the water sample is detected and the TEP level of the sample is determined.
