Solution Overview

Problem

Current methods for improving sleep quality, particularly during the falling asleep and awakening phases, are not adequately tailored to individual user preferences, activities, and environmental conditions, leading to suboptimal relaxation and wake-up experiences.

Innovation Solution

A system that uses a combination of a sensing mat, activity tracker, and central server to analyze sleep data and context information to provide personalized light and sound programs based on user-specific and group models, optimizing the falling asleep and awakening phases through tailored light and sound sequences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional sleep optimization methods are used (ambient temperature, air humidity control), then general sleep conditions are improved, but the falling asleep and awakening phases are not adequately optimized

Engineering Contradiction:
Improvesleep qualityVSAvoidtailoring to individual user preferences and activities
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary actions by analyzing user data (activity tracker information, sleep patterns, preferences) before the sleep phase begins, and before the awakening phase occurs. Light and sound programs are pre-configured based on daytime activities and user profiles, then automatically activated at appropriate times to optimize falling asleep and awakening experiences.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adapts light and sound programs based on real-time data from activity trackers, sleep sensors, and user feedback. The programs are not static but adjust according to individual user patterns, making the sleep optimization system versatile and personalized rather than conventional and one-size-fits-all.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If default or standard light and sound programs are used, then the system is simple to operate, but the relaxation phase and falling sleep phase are not appropriate for individual users

Engineering Contradiction:
Improvesystem simplicityVSAvoidpersonalization to user preferences and activities
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system performs self-service by automatically analyzing user data from activity trackers and sleep sensors, then selecting and configuring appropriate light and sound programs without requiring manual user input. The system learns user preferences and daytime activities autonomously, providing personalized programs while maintaining ease of operation through automation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system incorporates feedback loops where user responses to light and sound programs (sleep quality data, wake-up mood assessments) are continuously analyzed. This feedback refines future program selections, allowing the system to become increasingly personalized over time while maintaining simple operation for the user.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If standard wake-up procedures are used, then the alarm function is simple, but the user mood at wakeup is not optimized

Engineering Contradiction:
Improvealarm function simplicityVSAvoiduser mood at wakeup
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system prepares the awakening phase in advance by analyzing sleep stage data and configuring gradual light and sound programs before the alarm triggers. Instead of abrupt wake-up, the system pre-conditions the user's environment with appropriate sensory stimuli to facilitate a positive wake-up mood while keeping the alarm function itself simple.

Inventive Principle:
Principle #10Preliminary action
