Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nursing products cannot distinguish between different types of metabolites, such as liquid and non-liquid metabolites, leading to a lack of functionality in managing and preventing leakage.
Innovation Solution
Incorporating a humidity sensing module in the absorption portion of nursing products to detect humidity values at specific position points, determining growth state information, and using temperature sensing to differentiate between liquid, semi-solid, and solid metabolites based on humidity and temperature patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-function absorption portion is used in nursing products, then the device complexity is reduced and manufacturing is easier, but the ability to distinguish metabolite types is lost
Solution Approach 1:
The absorption portion is divided into multiple sensing regions with different humidity sensing capabilities. Each region detects humidity at different positions, and the pattern of humidity distribution across these segmented regions is used to identify metabolite types, enabling differentiation without requiring a single complex sensor
Solution Approach 2:
Different regions of the absorption portion are designed with different sensing characteristics or positions relative to expected metabolite deposition zones. The local humidity response at each position provides specific information about metabolite type, allowing the system to distinguish between liquid and non-liquid metabolites through spatially-resolved sensing
2Measurement precision
If multiple sensing modules are added to detect metabolite types, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The humidity sensing module serves multiple functions: it detects both the presence of metabolites and their types (liquid vs. non-liquid) based on humidity patterns. The same sensing elements are used for different detection purposes, eliminating the need for separate specialized sensors for each metabolite type
Solution Approach 2:
Instead of using multiple sensors at a single point, the system adds spatial dimension by distributing humidity sensing across multiple positions in the absorption portion. The metabolite type is identified through the spatial pattern of humidity distribution rather than through multiple sensors at one location, reducing overall device complexity

AI summary
In one aspect, a metabolite detection method is applied to a nursing article. An absorption portion of the nursing article is provided with a humidity sensing module for sensing a humidity value of a first position point set. The first position point set comprises at least one position point located on a metabolite diffusion path of the absorption portion. The metabolite detection method comprises: acquiring a humidity value of a first position point set, and determining growth state information of a position point according to the humidity value, the growth state information being used for representing the growth condition of the humidity of the position point over time; and determining a metabolite type according to the growth state information, the metabolite type comprising a liquid metabolite sand non-liquid metabolite.
