Solution Overview

Problem

Occupants in a moving vehicle experience short and disturbed sleep due to vibrations and noise, and individual sleep preferences and travel times vary, necessitating a system to provide customized sleep care.

Innovation Solution

A system that includes a biosensor to monitor vital signs, an input unit for occupant preferences, and a controller to adjust lighting, seating, sound, and air conditioning based on sleep state and preferences to create a customized sleep environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If occupants sleep in a moving vehicle, then occupant convenience and relaxation are improved, but sleep quality deteriorates due to vehicle vibrations and external noise

Engineering Contradiction:

Improveoccupant convenienceVSAvoidsleep quality

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system converts the harmful effects of vehicle vibrations and noise into beneficial sleep support by detecting them through sensors and automatically adjusting lighting, sound, and seating to counteract these disturbances, transforming the problematic moving vehicle environment into a suitable sleep environment

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The system continuously monitors occupant sleep state through biosensors and adjusts vehicle settings in real-time based on detected sleep quality, creating a closed-loop feedback system that maintains optimal sleep conditions despite vehicle motion and noise

Inventive Principle:

Principle #23Feedback

2Reliability

If the vehicle provides a customized sleep environment for each occupant, then individual sleep quality is improved, but device complexity increases

Engineering Contradiction:

Improveindividual sleep qualityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system uses a single integrated controller that manages multiple vehicle subsystems (lighting, sound, seating, air conditioning) to provide customized sleep environments for multiple occupants simultaneously, reducing overall system complexity through functional integration

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system divides the vehicle interior into multiple independent zones, each with its own sensors and actuators, allowing individualized sleep environment control for each occupant while maintaining system manageability through modular architecture

Inventive Principle:

Principle #1Segmentation
