Diaper Sheath With Front Flap And Removable Pad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant diapers face challenges in maintaining dryness and comfort due to rapid saturation, discomfort from tight elastic leg openings, and lack of adjustable leg retention, as well as issues with observing wetness and using absorbent inserts effectively.
Innovation Solution
A hybrid diaper sheath design featuring inner and outer panels with adjustable elastic strips and snap fasteners, a removable absorbent pad system, and a fleece inner panel for comfort, allowing for easy adjustment and use of biodegradable or disposable inserts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastic leg openings are used to ensure retention and prevent leakage, then the diaper provides better fit and retention, but it causes discomfort and hampers blood circulation in the child's legs
Solution Approach 1:
The patent removes the elastic leg openings entirely from the diaper design. Instead of using elastic material at the leg openings, the diaper relies on the snug fit of the overall diaper body and the absorbent core to prevent leakage, thereby eliminating the harmful effect of elastic on the baby's legs while maintaining retention functionality.
2Reliability
If the diaper is made snug to prevent leakage, then retention is improved, but it creates high humidity and moisture within the diaper causing discomfort
Solution Approach 1:
The patent employs composite material structure with a breathable outer cover material that allows moisture vapor transmission while providing a snug fit. The combination of the breathable outer layer and the absorbent core creates a system that maintains retention through snugness while simultaneously managing moisture and humidity through the breathable properties of the outer material.
3Adaptability or versatility
If hook and loop fasteners are used for waist adjustment, then waist fit is adjustable, but they do nothing for the leg openings leaving them unfitted
Solution Approach 1:
The patent removes the traditional hook and loop fastener system entirely. Instead of adding fasteners to adjust leg openings, the design relies on the overall snug fit of the diaper body and the absorbent core configuration to provide automatic adjustment and fit at the leg openings, eliminating the need for separate fastening mechanisms.
4Reliability
If outer waterproof covers are used to prevent moisture spread, then moisture containment is improved, but parents cannot observe that the diaper is already wet
Solution Approach 1:
The patent incorporates a wetness indicator system into the outer waterproof cover. This system uses color-changing material or visual indicators that change appearance when the absorbent core becomes saturated, allowing parents to observe wetness status through the waterproof cover without compromising the moisture containment functionality.

AI summary
The present invention provide with a diaper sheath comprising: an inner and outer panel, each of said inner and outer panels having front and back portion connected by an intermediate portion, said front portion of the inner panel having an opening; and a front flap attached to said front portion of said inner panel, and said opening is covered by said front flap. The diaper of the present invention is much easier and convenient to adjust the insert from the opening at the front portion. With the flap at the front portion, parents can choose to use a biodegradable pad to insert in the flap and lay on the top of the inner panel.
