Recloseable Diaper Package with Handle Cutout and Zip-Lock Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current disposable diaper packaging is inadequate as it can be bulky and awkward to carry, exposes diapers to humidity and contamination, and fails to keep them clean and dry, especially in humid or dusty environments.
Innovation Solution
A recloseable package design using a polymer film with a zip-lock closure mechanism that provides a moisture barrier and is easy to carry, featuring a handle cutout and a tear-away promotional portion, ensuring the diapers remain clean and dry until use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If diapers are packaged in block-shaped stacks enclosed in polymer film, then the package is neat and compact for shipment and retail display, but the package becomes bulky and awkward for consumers to carry
Solution Approach 1:
The package is divided into two functional zones: a compressed block-shaped section for neat stacking and shipping, and an expanded section with a large opening for easy consumer access and carrying. This segmentation allows the package to serve both retail display and consumer portability needs simultaneously.
Solution Approach 2:
The package transitions from a purely three-dimensional block shape to a more open, accessible configuration with a large opening. This dimensional change creates a hybrid form that maintains the compactness of the block while adding the functionality of an open container for easy carrying and access.
2Ease of operation
If the package is opened to access diapers, then consumers can use the diapers, but the remaining diapers are exposed to humidity, dust and dirt
Solution Approach 1:
The package is designed with a large opening from the beginning that allows consumers to access diapers without fully opening or compromising the package seal. This preliminary access design enables users to take out needed diapers while the remaining supply stays protected inside, eliminating the need to fully open the package and exposing contents to contaminants.
Solution Approach 2:
The large opening acts as an intermediary access point that allows interaction with the diaper supply without requiring full package opening. Consumers can reach through or access diapers at the opening while the main sealed portion remains intact, serving as a buffer that prevents direct exposure of the entire supply to environmental contaminants.
3Reliability
If superabsorbent particles are used in the absorbent core, then diaper absorbency is improved, but the particles can absorb water from the atmosphere in humid conditions and impart a damp feeling
Solution Approach 1:
The package maintains a sealed environment around the diapers with superabsorbent particles until the moment of use. This preliminary sealing prevents atmospheric moisture from reaching the particles during storage and transport, ensuring they remain dry and functional until actually needed, at which point the sealed protection is intentionally broken.
4Object-affected harmful factors
If a recloseable mechanism is added to the package, then diapers can be protected from contamination, but the device complexity increases
Solution Approach 1:
The recloseable mechanism is pre-configured in the package structure during manufacturing, with the closure components already in place and ready for use. This preliminary preparation allows consumers to simply perform the closing action without dealing with complex assembly or configuration, reducing the perceived complexity during actual use while maintaining effective contamination protection.

AI summary
A package formed of polymer film and containing disposable diapers is disclosed. The package may include mating zip-lock components at a top opening that enable the package to be recloseable, and top portions that extend upwardly beyond the mating zip-lock components, the top portions each having a handle cut therethrough.
