Diaper Band with Central Hook Fabric and Rear Closure

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Toddlers often manage to remove their diapers, leading to soiling and rebellion, as existing solutions like reinforced tape or additional clothing layers can cause skin irritation or are easily bypassed by determined children.

Innovation Solution

A diaper band with an inner elastic band, outer elastic fabric cover, and attachment straps with hook and loop materials is centered on the diaper, wrapped around the sides, and secured to the back, preventing access to the diaper tabs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If duct tape or medical tape is used to reinforce the sticky closure tabs, then the tabs cannot be opened by toddlers, but attachment to the skin causes rashes and determined toddlers can still peel off the tape

Engineering Contradiction:

Improvediaper securityVSAvoidskin irritation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a fabric-based closure system with loop material on the diaper and hook material on the band as an intermediary between the diaper and the toddler's skin. This fabric-based system eliminates direct skin contact with adhesive tapes, resolving the skin irritation problem while maintaining secure attachment through the hook-loop mechanism that toddlers cannot easily peel off.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If sleep sack is put on backwards to prevent diaper removal, then one more layer is added, but it can still be pulled down providing access to diaper closures

Engineering Contradiction:

Improvediaper securityVSAvoidlayering complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the security function from the clothing layers (sleep sack, pajamas) and places it directly on the diaper system through the elastic band with hook material. This eliminates the need for additional protective layers, reducing device complexity while maintaining reliable diaper security through the integrated closure band.

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If pajamas are put on backwards to prevent unzipping, then access to diaper is blocked, but determined toddlers can reach the diaper by puffing the waist away from the body

Engineering Contradiction:

Improvediaper securityVSAvoidapplication ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent moves the closure mechanism from the front abdominal area (where toddlers can reach) to the rear waist area. The elastic band with hook material is positioned at the back of the diaper, secured through the waist, making it inaccessible to toddlers while remaining easy for caregivers to apply and adjust from the front.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Ease of operation

If scissors are used to cut off adhered tape, then the toddler can be freed, but injury can occur if the toddler is restless

Engineering Contradiction:

Improveremoval easeVSAvoidinjury risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent uses fabric-based hook and loop materials as an intermediary that provides secure attachment without the need for cutting tools. The closure can be easily opened by pulling the tab, eliminating injury risk from scissors while maintaining reliable security against toddler removal attempts.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A diaper band for ensuring that a toddler cannot remove a diaper secured thereby. The diaper band has central inner-facing hook fabric that can be attached to the fabric on the front of a typical diaper (disposable or reusable). The diaper band also has ends bearing hook and loop material that are securable to the back of the diaper behind the back of the toddler, to ensure that the toddler cannot detach the diaper band. The diaper band securely covers the attachment tabs of the diaper, so that the toddler cannot undo the diaper tabs. The central inward-facing hook fabric can be one or more material patches that are big enough to grab onto the front fabric of the diaper, the same front fabric for attaching the diaper tabs. Alternatively, the central inward-facing hook material region can extend along the entire length of the diaper band.
