Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fecal gas analysis methods face challenges in accuracy due to time-sensitivity and variability in gas concentrations influenced by environmental factors and stool amount, making it difficult to consistently monitor gastrointestinal health.
Innovation Solution
A fecal gas component ratio analysis method that converts gas concentration measurements into component ratios, providing stable values over time, enabling accurate classification of Bristol stool types and health conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If absolute gas concentration values are measured to assess stool condition, then stool condition can be evaluated, but measurement accuracy is reduced due to variability from environmental factors and stool amount
Solution Approach 1:
The patent transforms the measurement parameter from absolute gas concentration (ppm) to component ratio (%). This parameter change makes the measurement independent of stool amount and environmental factors, as the ratio of fecal gas components remains constant regardless of total gas volume or measurement conditions, thereby resolving the contradiction between measurement precision and reliability
Solution Approach 2:
The patent introduces component ratio as an intermediary parameter that mediates between the measured gas concentrations and the final stool condition assessment. By using the ratio of fecal gas components rather than absolute concentrations, the system eliminates the direct influence of environmental variables and stool amount on the measurement results
2Ease of manufacture
If gas concentration measurements are delayed after stool collection, then laboratory analysis can be performed, but measurement accuracy decreases due to time-sensitivity of gas concentration
Solution Approach 1:
By changing the measurement parameter from time-sensitive absolute concentration to time-stable component ratio, the patent enables delayed measurement without accuracy loss. The component ratio remains constant over time, allowing laboratory analysis to be performed after stool collection while maintaining measurement precision
3Productivity
If absolute gas concentration is used for analysis, then gas measurement can be performed, but results vary significantly depending on stool amount and measurement environment
Solution Approach 1:
The patent applies parameter transformation from absolute concentration to component ratio, which normalizes the measurement across different stool amounts and environmental conditions. This allows the analysis capability to be maintained while achieving consistent results regardless of variability in stool amount or measurement environment
