Solution Overview
Problem
Current systems for monitoring nutrient intake in toilet spaces are cumbersome for users, requiring information beyond excretion-related data, thereby increasing the user's load and reducing convenience.
Innovation Solution
A nutrient intake amount estimation system that uses a sensor in the toilet space to detect excretion smells and estimates nutrient intake based on an estimation model, eliminating the need for user-provided meal information and simplifying the observation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image information of food and drink or bar code information is required to estimate nutrient intake, then the system can obtain comprehensive meal information, but the user load increases and the system becomes complicated
Solution Approach 1:
The patent extracts only the essential information needed for nutrient estimation (excretion-related data) and removes unnecessary information collection requirements (image information, bar code scanning, manual meal input). This allows the system to estimate nutrient intake using only excretion data from the toilet space, significantly reducing user load while maintaining estimation capability
Solution Approach 2:
The system performs nutrient intake estimation automatically using excretion data collected in the toilet space without requiring user intervention for meal information input. The estimation is conducted self-service style, where the system processes the data autonomously to generate nutrient intake results
2Measurement precision
If multiple types of information (image information, bar code information, meal information) are collected, then the nutrient estimation can be more accurate, but the device complexity increases
Solution Approach 1:
The patent extracts and utilizes only excretion-related information from the toilet space, eliminating the need for image recognition devices, bar code scanners, and meal input interfaces. This simplifies the device architecture while focusing on the most relevant data source for nutrient estimation
Solution Approach 2:
The system uses the excretion detection capability in the toilet space for dual purposes: monitoring excretion status and estimating nutrient intake. This multi-functional approach eliminates the need for separate meal monitoring devices, reducing overall system complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This system reduces the user's load by providing an accurate estimation of nutrient intake without requiring additional information, allowing for convenient monitoring of nutrient balance and suggesting improvements based on target and actual intake comparisons.
Implementation Method 1
