Sleep-Aware Appliance Notification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
If a user falls asleep without operating a household electrical appliance, the appliance does not operate in accordance with the user's intention, leading to a mismatch between the appliance's operation state and the user's intended settings.
Innovation Solution
An information processing apparatus that detects a user's sleep state using sensors and compares the appliance's operation state to predetermined normal information. If the states mismatch, the apparatus outputs a notification signal to awaken the user and encourage them to operate the appliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user falls asleep without operating the appliance, then the appliance cannot operate according to user's intention, but continuously monitoring and notifying the user may disturb their sleep
Solution Approach 1:
The notification timing is dynamically adjusted based on sleep depth parameters. The system monitors sleep state and selects notification moments when sleep depth is relatively shallow, changing the temporal parameter of notification delivery to minimize disturbance while ensuring user awareness
Solution Approach 2:
The system continuously monitors sleep state and provides feedback to determine optimal notification timing. By detecting sleep depth and state changes, the system adjusts notification delivery to achieve reliable appliance operation reminders without excessive sleep disturbance
2Loss of information
If the user is awoken from deep sleep state, then the user can be notified about appliance settings, but the user's sleep quality deteriorates and it becomes difficult to fall asleep again
Solution Approach 1:
The system monitors sleep depth parameters in real-time and dynamically adjusts notification timing based on these parameters. When shallow sleep states are detected, notifications are delivered; when deep sleep is detected, notifications are delayed, thereby preserving sleep quality while ensuring information transmission
Solution Approach 2:
The notification system transitions from a static, fixed-timing approach to a dynamic, adaptive approach that responds to real-time sleep state changes. The system flexibly adjusts notification delivery based on detected sleep depth and state transitions
3Ease of operation
If the notification is output when the user is in light sleep state, then the user can be awakened effectively, but the timing for notification is more difficult to detect and determine
Solution Approach 1:
The system introduces sleep state detection technology as an intermediary between the notification system and the user. This intermediary monitors physiological parameters and provides objective data about sleep depth, enabling effective timing determination without requiring complex manual assessment
Data Source
AI summary
A management apparatus includes an obtainer that obtains detected information from a sensor that detects sleep of a user; a sleep determiner that determines whether the user is in a sleep state, based on the detected information; a manager that is connected to an appliance via a network, and obtains state information indicating an operation state of the appliance; an appliance determiner that determines whether the state information is different from predetermined normal information indicating a normal operation state of the appliance, when the sleep determiner determines that the user is in the sleep state; and a notification controller that outputs a notification signal, when the appliance determiner determines that the state information is different from the normal information.
