Solution Overview

Problem

The complex and unstable nature of Iceland moss constituents makes it challenging to establish reliable quality control and quantitative determination in herbal products, as there are no known active markers, leading to inconsistencies and difficulties in ensuring product quality.

Innovation Solution

Ribitol and arabitol are used as analytical markers in high-performance anion exchange chromatography to quantify and identify Iceland moss herbal preparations in herbal products, providing a reliable method for quality control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional analytical methods are used for Iceland moss analysis, then the complexity of constituents and lack of stable markers make quality control difficult, but using ribitol and arabitol as analytical markers enables reliable quantitative determination and quality control

Engineering Contradiction:
Improvequality control reliabilityVSAvoidanalytical method complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses ribitol and arabitol as intermediary analytical markers to bridge the gap between the complex Iceland moss constituents and the analytical detection system. These markers serve as stable, detectable proxies that can be reliably measured to quantify the herbal preparation content, resolving the contradiction between reliability and complexity by introducing intermediate substances that are easier to analyze than the target constituents

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the analytical parameters by switching from conventional HPLC methods to high-performance anion exchange chromatography (HPAE), which is specifically suited for detecting the negatively charged ribitol and arabitol markers. This parameter change enables reliable detection of the markers despite the complex matrix, achieving both reliability and manageable complexity

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If ribitol and arabitol are used as analytical markers, then quantitative determination accuracy improves, but the method requires specific chromatographic conditions and marker selection

Engineering Contradiction:
Improvequantitative determination accuracyVSAvoidmethod implementation ease
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent establishes that ribitol and arabitol serve multiple functions: they act as analytical markers for quantification, as identification markers for species confirmation, and as quality control indicators. This multi-functionality improves measurement precision while actually simplifying implementation, as a single method can address multiple quality assurance requirements simultaneously

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

Solution Approach 2:

The patent creates analytical copies of the complex Iceland moss composition by using ribitol and arabitol as surrogate markers. These copies retain the essential quantitative information needed for quality control without requiring direct analysis of the complex mixture, thereby improving accuracy while reducing the practical difficulty of implementation

Inventive Principle:
Principle #26Copying

3Quantity of substance

If conventional HPLC methods are used, then analysis can be performed, but the unstable and low concentration constituents make consistent quantification difficult

Engineering Contradiction:
Improveconstituent concentration detectionVSAvoidconstituent stability
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The patent introduces ribitol and arabitol as stable intermediary markers that are more readily detectable than the unstable Iceland moss constituents. These markers serve as mediators that can be consistently quantified even when the target constituents are present at low concentrations and vary in stability, thereby improving detection of quantity while overcoming the stability problem

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces conventional HPLC detection mechanisms with high-performance anion exchange chromatography, which is specifically designed for detecting charged molecules like ribitol and arabitol. This substitution enables reliable detection of constituents at lower concentrations and improves measurement precision by utilizing the charge-based separation mechanism that is more sensitive to the analytical markers than conventional methods

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