Solution Overview

Problem

Current scientific technology faces challenges in accurately diagnosing tumors smaller than 1 mm in size, limiting early-stage cancer detection and treatment success.

Innovation Solution

A method involving the quantitative analysis of isotopes in blood or tissue samples, specifically measuring levels of elements like hydrogen, oxygen, magnesium, calcium, potassium, sulfur, chloride, silicon, iron, copper, and their isotopes, to identify cancer through comparisons with normal standards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional imaging and biopsy methods are used, then current diagnostic capabilities are maintained, but tumors smaller than 1 mm cannot be accurately detected

Engineering Contradiction:
Improvetumor detection accuracyVSAvoiddetection of small tumors
Core Design Contradiction:
Measurement precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces isotope analysis as an intermediary diagnostic tool between conventional imaging and cancer development. By measuring isotope ratios (such as 18O/16O, 13C/12C, 15N/14N) in blood or tissue samples, the method detects metabolic changes that occur before tumors become visible through traditional imaging, serving as an early warning system for sub-clinical cancer detection

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent detects cancer by monitoring changes in isotopic composition parameters rather than relying on tumor size or morphological parameters. The method measures deviations in isotope ratios (e.g., increased 18O/16O ratio, altered 13C/12C ratio) that reflect metabolic reprogramming in cancer cells, enabling detection of biochemical changes before anatomical changes occur

Inventive Principle:
Principle #35Parameter changes

2Reliability

If early-stage cancer detection is achieved through isotope analysis, then treatment success probability increases, but diagnostic complexity increases

Engineering Contradiction:
Improvecancer diagnosis reliabilityVSAvoidisotope analysis system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and measures specific isotopic signals from complex biological samples by isolating the isotopic composition data from other variables. Using techniques like isotope ratio mass spectrometry, the method selectively measures isotope ratios (such as 18O enrichment, 13C/12C ratios) while filtering out confounding factors, thereby simplifying the diagnostic readout to a focused set of cancer-relevant isotopic parameters

Inventive Principle:
Principle #2Taking out (Extraction)
