Solution Overview

Problem

Current methods for diagnosing ovarian cancer are inadequate for early detection, as most cases are not caught in the earliest stage due to vague symptoms and the lack of an effective test for early and accurate detection.

Innovation Solution

A method involving the measurement of specific biomarker panels in bodily fluids, such as blood serum, using a multianalyte panel assay to predict and diagnose ovarian cancer, particularly for epithelial ovarian cancer, by identifying a detectable molecular signature associated with the disease.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If current diagnostic methods are used, then the diagnostic process is simple, but the detection accuracy for early-stage ovarian cancer is low

Engineering Contradiction:
Improvedetection accuracyVSAvoiddiagnostic method complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple biomarker measurements (CA125, HE4, and other proteins) into a single integrated diagnostic assay. This multianalyte approach merges several detection functions into one test system, achieving high detection accuracy for early-stage ovarian cancer while maintaining practical clinical usability through a unified diagnostic protocol.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The diagnostic method serves multiple functions: it detects early-stage ovarian cancer, differentiates between malignant and benign conditions, and provides risk stratification. This multi-functional approach allows a single diagnostic system to address various clinical needs, improving overall detection accuracy across different disease stages and presentations.

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

2Reliability

If early-stage ovarian cancer is detected, then the survival rate increases significantly, but current methods fail to detect most early-stage cases

Engineering Contradiction:
Improveearly detection reliabilityVSAvoiddetection difficulty
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent focuses on detecting specific local changes in biomarker levels that are characteristic of early-stage ovarian cancer. By measuring particular proteins and their concentration ratios rather than general markers, the method achieves reliable early detection by identifying localized molecular signatures specific to the disease state.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The diagnostic method performs preliminary detection of ovarian cancer through biomarker measurement before clinical symptoms manifest or disease progression occurs. This preliminary action enables early intervention and treatment planning, significantly improving survival outcomes by detecting cancer at a treatable stage.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If a single biomarker test is used, then the test is simple to perform, but the sensitivity and specificity are insufficient for accurate diagnosis

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidassay complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges multiple biomarker measurements into a single integrated diagnostic assay. By simultaneously measuring CA125, HE4, and other proteins in one test system, it achieves high diagnostic accuracy with sensitivity and specificity rates of at least 85%, while maintaining practical usability through a unified testing protocol.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The diagnostic approach uses a composite biomarker profile rather than a single marker. It combines information from multiple proteins and their relative concentrations to create a composite diagnostic indicator, achieving superior accuracy by leveraging the complementary strengths of different biomarkers in a unified assessment.

Inventive Principle:
Principle #40Composite materials
