Solution Overview

Problem

Current methods for predicting gestational diabetes mellitus (GDM) are inadequate, as there is a lack of reliable biomarkers for early detection during pregnancy, which hinders timely intervention and management.

Innovation Solution

The use of Secreted Frizzled-Related Protein 4 (sFRP4) levels in biological samples, such as blood, to identify pregnant women at risk of developing GDM by comparing expression levels to a reference sample, with increased sFRP4 levels indicating a higher risk.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If prenatal screening methods are used for GDM diagnosis, then GDM can be detected during pregnancy, but the detection is not early enough and lacks reliable biomarkers for timely intervention

Engineering Contradiction:
Improvedetection accuracyVSAvoidtime for intervention
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by measuring sFRP4 expression levels early during pregnancy (first trimester) to predict GDM risk before clinical symptoms appear. This allows intervention to be planned in advance rather than waiting for later diagnosis, thus reducing the loss of time while maintaining detection accuracy through reliable biomarker measurement

Inventive Principle:
Principle #10Preliminary action

2Reliability

If existing biomarkers for T1D and T2D are used, then some prediction capability is available, but these biomarkers are not suitable for GDM prediction

Engineering Contradiction:
Improvebiomarker reliabilityVSAvoidbiomarker applicability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by identifying sFRP4 as a specific biomarker with properties tailored for GDM prediction, rather than using general diabetes biomarkers. The sFRP4 biomarker has local specificity to pregnancy-related metabolic changes, making it reliably applicable only to GDM prediction while maintaining high reliability for this specific condition

Inventive Principle:
Principle #3Local quality
