Solution Overview
Problem
Existing bathing information systems fail to effectively associate objective and subjective information for bathers, leading to discomfort even when objective conditions are satisfactory, and making it difficult for bathers to achieve comfortable bathing by comparing subjective and objective information.
Innovation Solution
A bathing information system that includes a bather specifying unit, an information acquisition unit for objective information, and a program that stores and associates subjective information with objective information to create a bathing history, allowing for the output of history information to help bathers adjust their bathing methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only objective information (heart rate, temperature) is provided to bathers, then the information can be easily measured and displayed, but the bather cannot understand the relationship between objective information and their subjective comfort
Solution Approach 1:
The patent combines objective information (heart rate, body temperature, bathing conditions) with subjective information (bather's comfort level, satisfaction) into a unified bathing management system. The controller integrates data from sensors measuring objective parameters with user inputs regarding subjective comfort, creating a comprehensive bathing history that correlates both types of information for better bathing guidance.
2Adaptability or versatility
If subjective information from multiple bathing histories is stored and analyzed, then bathers can compare and achieve more comfortable bathing, but the system complexity increases
Solution Approach 1:
The bathing management system automatically collects, stores, and analyzes bathing data without requiring complex manual intervention. The controller autonomously manages the bathing history database, performs comparisons across multiple bathing sessions, and provides guidance recommendations, reducing the operational complexity for users while maintaining high adaptability.
Solution Approach 2:
The system implements feedback mechanisms where bathing results (both objective measurements and subjective comfort ratings) are stored and used to generate guidance for future bathing sessions. This closed-loop feedback allows the system to learn from past experiences and provide increasingly personalized recommendations without proportionally increasing system complexity.
3Reliability
If bathing guidance is provided based on both objective and subjective information comparison, then more accurate bathing recommendations can be made, but the information processing requirement increases
Solution Approach 1:
The system processes and stores comprehensive bathing data including both objective measurements and subjective information, but provides guidance based on the most relevant correlations discovered through analysis. Rather than processing all possible data combinations in real-time, the system identifies key patterns from bathing histories and uses those for guidance, reducing processing energy while maintaining reliability.

AI summary
There is provided a bathtub apparatus in which a bather can confirm objective information in association with subjective information by history information based on a plurality of bathing histories. A bathing information system of the present invention includes a bather specifying unit, an information acquisition unit that acquires objective information, and program that controls a controller to store subjective information input by the bather in the controller, the program causing a controller to store a bathing history obtained by associating objective information A acquired by the information acquisition unit regarding specific bathing of a specified bather with subjective information B input by the bather specified for the specific bathing and causing the controller to implement an output function of outputting, to an output device, history information based on a plurality of bathing histories for the specified bather.
