Information providing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack effective means to provide timely and non-disruptive notifications for user excretion, particularly in scenarios where caregivers need to change diapers, often disturbing the user's sleep or failing to alert them appropriately.
Innovation Solution
An information providing device equipped with a processor that acquires signals from both an excretion sensor and a sleep sensor, outputting a notification only when the user is awake and excreting, thereby minimizing sleep disturbance and optimizing caregiver efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a notification signal is output whenever excretion is detected, then caregiver efficiency is improved through timely alerts, but user sleep is disturbed by unnecessary notifications during sleep hours
Solution Approach 1:
The notification system dynamically adjusts its behavior based on the user's sleep state. The processor determines whether to output notifications by considering both excretion detection results and sleep state information, making the notification function adaptive rather than static. This resolves the contradiction by enabling timely notifications during wakeful periods while suppressing them during sleep periods.
Solution Approach 2:
The system changes the notification parameter (output state) based on the sleep state parameter. When the sleep state changes from wakeful to sleeping, the notification parameter transitions from active to inactive. This parameter-based control allows the system to maintain caregiver efficiency during daytime while eliminating sleep disturbance during nighttime.
2Object-affected harmful factors
If notifications are suppressed during sleep, then user comfort is improved, but timely excretion information may be lost when the user wakes up unexpectedly
Solution Approach 1:
The system continuously monitors both sleep state and excretion detection results, using this feedback to determine notification timing. When the user transitions from sleep to wakeful state, the system receives feedback about the current state and can then output accumulated excretion information at the appropriate moment, ensuring neither comfort nor information completeness is compromised.
Solution Approach 2:
The system preliminarily records excretion information during sleep periods without outputting notifications. This preliminary action ensures that excretion data is preserved and will be notified once the user wakes up, maintaining both user comfort during sleep and information completeness for timely care after waking.

AI summary
An information providing device capable of more adequately providing information regarding excretion is provided. According to one embodiment of the invention, the information providing device includes a processor. The processor acquires a first signal and a second signal. The first signal is obtained from an excretion sensor to detect excretion of a user. The second signal is obtained from a sleep sensor to detect a sleep state of the user. The processor outputs a notification signal for notifying the excretion when the first signal includes first information corresponding to a fact that the user is excreting, and the second signal includes second information corresponding to a fact that the user is awake. The processor does not output the notification signal in a first mode when the first signal includes the first information and, the second signal does not include the second information.
