Solution Overview

Problem

Existing systems for changing absorbent articles are inconvenient, non-hygienic, and fail to capture the emotional and environmental nuances of caregivers and wearers, disrupting daily activities and potentially causing behavioral or mood changes.

Innovation Solution

A system that includes a memory device storing acoustic signature models of absorbent article changes, an auditory capture mechanism to monitor sound profiles, and a processor to analyze these profiles in conjunction with environmental inputs like time and attitude recognition, generating outputs through visual, audible, or olfactory means to enhance the change experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automated sensors are used to detect absorbent article changes, then the convenience and hygiene are improved, but the ability to capture emotional and environmental nuances is lost

Engineering Contradiction:
Improveconvenience of absorbent article change detectionVSAvoidemotional and environmental context information
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent combines multiple sensing modalities (acoustic sensors for sound detection, environmental sensors for temperature/humidity, and attitude recognition technology) into a unified monitoring system. This merging allows the system to capture both the functional aspect of diaper changes and the emotional/environmental context, resolving the contradiction between automation convenience and information completeness

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The monitoring system is designed to perform multiple functions simultaneously: detecting absorbent article changes through acoustic signatures, monitoring environmental conditions, recognizing caregiver and wearer attitudes, and providing contextualized alerts. This multi-functionality ensures that no critical information is lost while maintaining automated convenience

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Device complexity

If manual manipulation is used to start or stop monitoring, then the system simplicity is maintained, but the convenience and hygiene are reduced

Engineering Contradiction:
Improvesystem operational simplicityVSAvoidconvenience of absorbent article change monitoring
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The system automatically activates and deactivates monitoring based on detected acoustic signatures of absorbent article changes. The acoustic sensors continuously monitor for specific sound patterns, and when a change is detected, the system autonomously initiates the alert sequence without requiring manual activation. This self-service approach maintains simplicity while dramatically improving convenience

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary detection and analysis of acoustic signatures before triggering alerts. By continuously monitoring and pre-processing audio data in the background, the system is ready to immediately respond to changes without requiring manual intervention, thus maintaining both simplicity and convenience

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If simple motion or noise detection sensors are used, then the device complexity is reduced, but the measurement precision of emotional and environmental inputs is insufficient

Engineering Contradiction:
Improvesensor system complexityVSAvoiddetection of emotional and environmental nuances
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The monitoring system is segmented into specialized functional modules: acoustic signature detection for change identification, environmental sensing for contextual data, attitude recognition for emotional context, and centralized processing for integration. This segmentation allows each module to be optimized for its specific function while maintaining overall system manageability, achieving high measurement precision without excessive complexity

Inventive Principle:
Principle #1Segmentation

4Object-affected harmful factors

If frequent absorbent article changes are monitored and addressed, then the wearer comfort is improved, but the caregiver productivity is reduced

Engineering Contradiction:
Improvewearer discomfort from soiled absorbent articlesVSAvoidcaregainer daily activity flow
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The system provides real-time feedback to caregivers through alerts and notifications when absorbent article changes are needed. This immediate feedback enables caregivers to address changes promptly, improving wearer comfort. Simultaneously, the system's automated detection and notification capabilities allow caregivers to plan and batch changes efficiently, minimizing disruptions to their overall productivity and daily activity flow

Inventive Principle:
Principle #23Feedback

AI summary

A system for intervening in an absorbent article change process by a user to improve the experience of the absorbent article change process is disclosed. The system can include a memory device, an auditory capture mechanism, and a processor. The memory device can be configured to store an absorbent article acoustic signature model. The absorbent article acoustic signature model can be indicative of a potential change of the absorbent article. The processor can be configured to analyze a captured potential use sound profile in relation to the absorbent article acoustic signature model and to interpret the first qualifying match in view of at least one environmental input. The system can be configured to selectively generate a first output based on the first qualifying match and the at least one environmental input. The first output can be recognizable by the user through visual, audible, or olfactory senses.
