Solution Overview

Problem

Young children and bedridden patients often require timely care during sleep to prevent moisture-related issues, such as sweating or urine-wetting, which can lead to illnesses due to unsanitary conditions.

Innovation Solution

A sleep monitoring apparatus using short-wave infrared imaging and a moving target detection algorithm, combined with moisture content analysis, to detect sweating or urine-wetting and notify caregivers through an alarm system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If parents manually check on sleeping children, then they can notice wet clothes, but they cannot provide timely notification and response

Engineering Contradiction:

Improvetimely care notificationVSAvoidresponse delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The monitoring system automatically detects moisture conditions and sends notifications without requiring parental intervention, enabling the system to serve itself in monitoring and alerting functions

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system provides real-time feedback to parents through notifications when moisture is detected, creating a closed-loop information system that enables timely response

Inventive Principle:

Principle #23Feedback

2Measurement precision

If traditional monitoring methods are used, then device complexity is low, but measurement precision of moisture content is insufficient

Engineering Contradiction:

Improvemoisture content detection accuracyVSAvoidmonitoring system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces manual visual inspection with automated infrared thermal imaging technology, substituting mechanical observation with optical detection to achieve precise moisture content measurement

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system detects changes in thermal parameters (temperature differences caused by evaporation) to infer moisture content, transforming the detection approach from direct moisture measurement to indirect thermal parameter analysis

Inventive Principle:

Principle #35Parameter changes

3Reliability

If continuous monitoring is implemented, then care quality improves, but energy consumption increases

Engineering Contradiction:

Improvemonitoring reliabilityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs periodic monitoring at appropriate intervals during sleep rather than continuous monitoring, reducing energy consumption while maintaining effective detection capability

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system maintains continuous monitoring capability throughout the sleep period, ensuring that moisture events are detected regardless of when they occur, while optimizing energy usage through efficient detection algorithms

Inventive Principle:

Principle #20Continuity of useful action
