Solution Overview

Problem

Current sleep management systems face challenges in reliably determining awakening timing due to errors in data acquisition and transmission, which can disrupt the user's sleep cycle.

Innovation Solution

A sleep management system that includes a determiner to determine awakening timing using a first index, and a secondary index to ensure accurate timing notification even when a fatal error occurs, utilizing biological and non-biological data to adjust awakening times.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the system uses a single index for determining awakening timing, then the determination process is simple, but the reliability of awakening timing determination deteriorates when data acquisition fails

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system prepares multiple indices (first index based on biological data, second index based on non-biological data) in advance before sleep occurs. When the user goes to sleep, both indices are ready to be used immediately - the first index for normal operation and the second index as a pre-prepared backup in case of data acquisition failure, eliminating the need for complex real-time switching logic.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system establishes a backup determination method (second index) beforehand to cushion against potential failures of the primary method (first index). This backup mechanism is activated only when needed, providing reliability protection without adding complexity to the normal operational flow.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Reliability

If the system switches to a secondary index when primary data fails, then the reliability of awakening timing determination is improved, but the device complexity increases

Engineering Contradiction:

Improveawakening timing determination reliabilityVSAvoidsystem structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Both the first index (biological data-based) and the second index (non-biological data-based) are prepared and stored in advance. The system architecture includes predetermined switching logic that selects between these pre-prepared indices, avoiding the need for complex real-time data processing and index generation during critical sleep determination moments.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes the parameter source from biological data (first index) to non-biological data (second index) based on data availability. This parameter switching mechanism is implemented through simple conditional logic that selects between pre-defined index types, maintaining reliability while minimizing structural complexity through straightforward parameter substitution rather than complex system reconfiguration.

AI summary

A sleep management system according to an aspect of the present disclosure includes a first determiner configured to determine awakening timing of a user and an awakener configured to notify the user of the awakening timing in accordance with a determination result of the first determiner. In the sleep management system, a second determiner is able to determine the awakening timing in accordance with a second index when a trouble occurs in determination of the awakening timing based on a first criterion.
