Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack effective means to determine the presence and association of methanogens with diseases such as obesity, pre-diabetes, diabetes, insulin resistance, and gastrointestinal disorders, and to select appropriate treatments based on methanogen quantities in biological samples.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If methanogen quantity analysis is performed using qPCR to enable targeted therapy selection, then treatment effectiveness for methanogen-associated diseases is improved, but diagnostic complexity and cost increase
Solution Approach 1:
The patent replaces complex culture-based diagnostic methods with qPCR technology, substituting mechanical/biological cultivation processes with a molecular amplification system. This allows direct detection of methanogen DNA in stool samples without requiring complex anaerobic culture conditions, thereby improving reliability while managing diagnostic complexity through standardized molecular protocols
Solution Approach 2:
The patent introduces methanogen-specific qPCR assays as an intermediary diagnostic tool that bridges the gap between sample collection and therapy selection. The qPCR method serves as a mediator that converts complex microbial presence into a quantifiable DNA signal, enabling straightforward interpretation and targeted treatment decisions without requiring direct observation or complex cultural analysis
2Measurement precision
If methanogen-specific qPCR assays are developed to detect methanogens in stool samples, then diagnostic precision is improved, but manufacturing and implementation complexity increase
Solution Approach 1:
The patent segments the diagnostic approach into distinct methanogen-specific qPCR assays targeting different methanogen species or genera. This segmentation allows for precise detection of specific methanogens while using standardized qPCR methodology, thereby improving measurement precision without requiring complete redesign of the entire diagnostic system - the molecular biology platform remains consistent while only the target-specific primers and probes need to be customized
Solution Approach 2:
The patent utilizes parameter changes in the qPCR assay design, such as adjusting primer sequences, probe fluorescence labels, and thermal cycling conditions, to optimize detection of different methanogens. These parameter adjustments allow for species-specific detection while maintaining the same fundamental assay platform, improving precision without proportionally increasing manufacturing complexity
3Reliability
If therapy selection is based on methanogen quantity comparison to reference values, then treatment appropriateness is improved, but time required for diagnosis increases
Solution Approach 1:
The patent establishes reference values for methanogen quantities in stool samples as a preliminary diagnostic framework before patient testing. These pre-determined reference ranges allow for immediate comparison with patient results, enabling rapid determination of whether methanogen levels indicate disease presence and guide appropriate therapy selection without requiring additional interpretive steps or prolonged analysis
Solution Approach 2:
The patent implements a feedback mechanism where methanogen quantity results are directly compared against established reference values to determine treatment appropriateness. This feedback loop provides immediate clinical guidance - if methanogen levels exceed reference thresholds, specific therapies are indicated; if below thresholds, alternative treatments are appropriate - thereby improving treatment appropriateness while minimizing diagnosis time through automated interpretation algorithms
