Solution Overview

Problem

Existing diaper devices lack a convenient and efficient system for replacing soiled diapers and disposing of them without needing to carry multiple diapers, especially in situations where additional diapers are not readily available.

Innovation Solution

A diaper assembly comprising a first diaper with a first absorbent pad and a second diaper removably attached, along with a first pouch containing pre-moistened wipes and a second pouch with a storage bag for disposing of the second diaper, allowing for easy replacement and disposal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single diaper is used, then the device complexity is low, but the ease of operation deteriorates when diaper replacement is needed

Engineering Contradiction:
Improveease of diaper replacementVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The diaper system is segmented into a first diaper and a second diaper that can be independently attached and detached. The second diaper is removably attached to the first diaper, allowing the soiled second diaper to be replaced without removing the entire diaper system, thus improving ease of operation while maintaining manageable complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second diaper is nested within or attached to the first diaper structure. This nesting arrangement allows the second diaper to be integrated into the overall diaper system while remaining independently replaceable, resolving the contradiction between operational ease and device complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If no storage bag is provided, then the device complexity is low, but the ease of operation deteriorates when disposing of soiled diapers

Engineering Contradiction:
Improveease of diaper disposalVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The storage bag is merged with the diaper system by attaching it to the first diaper. This combination integrates the disposal function into the existing diaper structure, improving ease of operation for diaper disposal while avoiding the need for separate disposal equipment, thus managing device complexity effectively.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The storage bag acts as an intermediary component between the soiled second diaper and the final disposal location. It provides a convenient intermediate storage solution that simplifies the disposal process by containing the soiled diaper, improving ease of operation without significantly increasing overall system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If wipes are not included, then the device complexity is low, but the ease of operation deteriorates when cleaning the user

Engineering Contradiction:
Improveease of user cleaningVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The wipes are merged with the diaper system by attaching the storage container to the first diaper. This integration combines the cleaning function with the diaper system, improving ease of operation for user cleaning while maintaining manageable device complexity through a unified design approach.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A multiple use diaper assembly includes a first diaper and a first absorbent pad is attached to the first diaper to absorb bodily fluids from the user. A second diaper is removably attached to the first diaper which rests against the user when the first diaper and the second diaper are worn on the user. A second absorbent pad is attached to the second diaper to absorb bodily fluids from the user. A first pouch is attached to the first diaper and a second pouch is attached to the first diaper. A plurality of wipes is stored in the first pouch and each of the plurality of wipes is pre-moistened to clean the user of bodily fluids. A storage bag is contained in the second pouch thereby facilitating the second diaper to be disposed of.
