Image-Based Stool Judgement for Mixed-Stool Constipation Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stool judgement systems fail to provide sufficient information for early detection of constipation in elderly individuals, leading to potential misdiagnosis and inappropriate care due to insufficient detection of subtle changes in stool properties and amounts, especially in cases where constipation stools are mixed with normal stools.
Innovation Solution
An excrement judgement system that captures images of defecation actions to determine properties and amounts of multiple stools, allowing for detailed analysis and output of associated information to display devices, enabling early detection of constipation tendencies and appropriate care.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional stool judgement systems determine only representative stool properties, then the system complexity is reduced and ease of operation is improved, but measurement precision and reliability of constipation detection deteriorate
Solution Approach 1:
The patent segments the stool analysis into multiple independent property evaluations. Instead of determining a single representative stool property, the system analyzes multiple stool properties including consistency, color, shape, and amount separately. This segmentation allows comprehensive detection of constipation indicators while maintaining systematic and manageable analysis processes.
Solution Approach 2:
The patent adds temporal dimension to stool analysis by examining changes in stool properties over time. The system compares current stool properties with historical data to detect subtle changes that indicate constipation tendencies. This dimensional expansion enables early detection while maintaining operational simplicity through automated comparison algorithms.
2Reliability
If conventional systems only detect obvious property changes, then device complexity is reduced, but reliability of early constipation detection deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors stool properties and compares them against established norms and historical data. When subtle changes are detected, the system provides feedback alerts to healthcare providers. This feedback loop enhances reliability by enabling early detection while keeping device complexity manageable through automated analysis algorithms.
Solution Approach 2:
The system performs preliminary analysis of stool properties to identify early signs of constipation before obvious symptoms appear. By conducting preliminary detection of subtle changes in stool consistency, color, and amount, the system enables early intervention while maintaining relatively simple device architecture through pre-programmed analysis criteria.
3Loss of information
If the system analyzes multiple stool properties and amounts, then information completeness for health management is improved, but loss of information is reduced and processing efficiency maintains
Solution Approach 1:
The patent extracts only the most relevant stool properties for constipation detection, such as consistency, color, shape, and amount, rather than analyzing all possible parameters. This selective extraction approach maintains information completeness for health management purposes while preserving processing efficiency by focusing on key indicators.
Solution Approach 2:
The system monitors changes in stool parameters over time rather than analyzing absolute values in isolation. By tracking parameter changes in stool properties, the system maintains comprehensive information for detecting constipation tendencies while improving processing efficiency through change-detection algorithms that require less computational resources than full parameter analysis.
