Solution Overview
Problem
Current methods for diagnosing cancer and other diseases are costly, time-consuming, and pose health risks, while breath sample analysis lacks efficient methods to correlate with physiological and disease states.
Innovation Solution
Utilizing an array of sensors with organic semiconducting materials to detect volatile organic compounds in biogas samples, such as breath, by analyzing the response patterns of these materials to identify specific volatile compounds, allowing for early detection of diseases like cancer without identifying individual components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional diagnostic procedures (mammograms, MRIs, biopsies, CT scans, colonoscopies) are used to detect cancer, then diagnostic accuracy is improved, but cost increases and patient health risks increase
Solution Approach 1:
The patent uses breath condensate as an intermediary medium to access biological information about cancer. Instead of directly invading the tumor site through biopsies or imaging, the system collects volatile organic compounds from breath that serve as indirect markers of cancer presence, thereby maintaining diagnostic accuracy while eliminating direct tissue invasion and associated health risks
Solution Approach 2:
The patent replaces mechanical and radiation-based diagnostic systems (biopsies, CT scans, mammograms) with a chemical sensing system. The sensor array detects chemical signatures (volatile organic compounds) in breath condensate, substituting physical invasion and radiation exposure with non-invasive chemical analysis, thus maintaining detection capability while reducing harmful effects on patients
2Measurement precision
If traditional diagnostic procedures are used to detect cancer, then diagnostic accuracy is improved, but time consumption increases
Solution Approach 1:
The patent enables early detection of cancer by analyzing breath condensate before traditional symptoms manifest. The sensor array can identify cancer markers in respiratory volatiles at early stages, allowing preliminary diagnosis and intervention before the disease progresses to stages requiring more invasive and time-consuming procedures
Solution Approach 2:
The patent replaces time-consuming mechanical diagnostic procedures (biopsies requiring tissue processing, CT scans requiring sequential imaging) with rapid chemical sensing. The sensor array provides quick detection of volatile organic compound patterns, significantly reducing the time needed for diagnosis while maintaining accuracy
3Object-affected harmful factors
If breath sample analysis is used to detect disease states, then cost is reduced and patient risk is minimized, but measurement precision deteriorates due to lack of efficient correlation methods
Solution Approach 1:
The patent transforms breath analysis from a qualitative assessment to a quantitative measurement system. By calibrating sensor responses to specific volatile organic compounds and establishing correlation patterns with disease states, the system achieves precise disease detection through breath condensate analysis, maintaining low cost and risk while improving measurement accuracy
Solution Approach 2:
The patent implements a feedback mechanism where sensor array responses are continuously compared against reference patterns and disease state correlations. This feedback loop refines the detection algorithm, improving the precision of disease state identification while maintaining the simplicity and low-risk nature of breath sampling
