Disposable Diaper With Integrated Soil Pouch For Hygienic Waste Containment

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing disposable baby diapers require cumbersome handling and cleaning after soiling, as they need to be gently cleaned and then disposed of, lacking integrated solutions for efficient containment and disposal of soiled materials.

Innovation Solution

A disposable diaper design featuring a wet wipe pouch and a soil pouch with closable ends, allowing the diaper to be inverted inside the soil pouch for containment of soiled parts, with closure mechanisms like adhesive tape or rib-and-groove systems to keep the soiled diaper enclosed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a disposable diaper is used, then convenience of disposal is improved, but cumbersome handling and cleaning after soiling remains

Engineering Contradiction:

Improveconvenience of disposalVSAvoidtime for cleaning and handling

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The diaper is inverted inside the soil pouch, with the soiled diaper nested within the pouch. The pouch contains the soiled diaper completely, allowing for easy disposal without handling the soiled portions directly. This nesting approach eliminates the need for separate cleaning steps while maintaining hygienic disposal.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The diaper system is segmented into functional portions: a wet wipe pouch for cleaning the baby, and a soil pouch for containing the soiled diaper. This segmentation allows each component to serve its specific purpose efficiently, with the soil pouch providing dedicated containment for waste material.

Inventive Principle:

Principle #1Segmentation

2Productivity

If integrated pouches are added to the diaper, then containment and disposal efficiency is improved, but device complexity increases

Engineering Contradiction:

Improvedisposal efficiencyVSAvoidstructure complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The soil pouch is integrated directly into the diaper structure, merging the containment function with the diaper itself. The pouch is formed as part of the diaper body, eliminating the need for separate containment devices and simplifying the overall system while improving disposal efficiency.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The soil pouch serves multiple functions: it contains soiled diapers, provides a barrier for hygienic disposal, and enables the inversion mechanism for secure containment. This multi-functionality reduces the need for additional separate components, maintaining simplicity while achieving efficient disposal.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If the diaper is inverted into the pouch, then secure containment of soiled parts is improved, but ease of operation during inversion may be worsened

Engineering Contradiction:

Improvecontainment securityVSAvoidinversion difficulty

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The pouch is designed with dynamic flexibility, allowing it to expand and contract during the inversion process. The material properties enable smooth inversion motion while maintaining containment integrity. The pouch adapts its shape during inversion to facilitate easy manipulation while ensuring secure containment of the soiled diaper.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The pouch is constructed from flexible thin film material that allows easy inversion while maintaining structural integrity. The flexibility of the film enables smooth turning inside out without tearing or breaking, making the inversion process simple and reliable for containing the soiled diaper.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A disposable diaper has a front pouch with a wet wipe inside and a rear pouch with a closable open end. When the diaper has been soiled the wet wipe can be removed from the front pouch and used to clean the baby and then the diaper, once removed from the baby, can be inverted into the rear pouch, which inverts inside out with the soiled diaper inside. A closure can be used to close the open end of the now-inverted rear pouch to contain the soiled diaper inside.
