Solution Overview

Problem

Current technologies lack sufficient proposals for controlling the sleeping environment to ensure a user wakes up at a predetermined time effectively, as the timing of such control is not appropriately executed.

Innovation Solution

An information processing device and method that forecasts the transition of a user's sleep depth and adjusts the sleeping environment accordingly, deciding a temporal pattern of control to ensure the user wakes up at a predetermined time by managing factors like room brightness, temperature, and sound, based on estimated sleep thresholds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sleeping environment control is executed to help user awake at predetermined time, then user can wake up smoothly, but control timing may be inappropriate causing failure to awake

Engineering Contradiction:

Improvereliability of waking upVSAvoidcontrol timing accuracy

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary forecasting of sleep depth transition before the predetermined wake-up time. By predicting future sleep depth based on current sleep state and temporal patterns, the system determines optimal control timing in advance, ensuring control is executed at the most appropriate moment to reliably wake the user.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors actual sleep depth and compares it with forecasted values. This feedback mechanism allows the system to adjust control timing dynamically, improving the accuracy of control execution and ensuring reliable wake-up by compensating for deviations from predicted sleep patterns.

Inventive Principle:

Principle #23Feedback

2Ease of operation

If sleeping environment control is executed at fixed timing, then control simplicity is maintained, but adaptability to individual sleep patterns is reduced

Engineering Contradiction:

Improvecontrol execution simplicityVSAvoidadaptability to sleep depth transition

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system transitions from fixed timing control to dynamic timing control based on forecasted sleep depth transitions. By adapting control timing to individual users' sleep patterns and predicted transitions, the system maintains ease of operation while significantly improving adaptability to varying sleep depths and personal rhythms.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the timing parameter of control execution based on forecasted sleep depth transitions. Instead of using a fixed time schedule, the system adjusts control timing according to predicted sleep state changes, enabling adaptability to individual patterns while keeping the control mechanism simple through automated parameter adjustment.

Inventive Principle:

Principle #35Parameter changes
