Diaper Folding Device with Cut-Out Pad for Flap Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for folding disposable worn articles, such as diapers, do not effectively address the folding of flaps at the crotch portion and attachment of these flaps to the torso portions.
Innovation Solution
A folding device and system that includes a main folding mechanism for folding the diaper body in two at the crotch portion and a sub-folding mechanism for attaching the flap to the non-skin-contact surface of the torso portion, utilizing cut-outs on the second main pad to expose the attachment portion and allow the flap to be securely attached, with side pads rotating to fit into these cut-outs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the second main pad holds the entire second torso portion, then the holding stability is improved, but the flap cannot be attached to the attachment portion
Solution Approach 1:
The second main pad is segmented by forming a cut-out at the position corresponding to the attachment portion. This segmentation allows the pad to hold the majority of the second torso portion while exposing the attachment portion for flap attachment, resolving the contradiction between holding stability and flap attachment capability.
Solution Approach 2:
The attachment portion is extracted from the holding area of the second main pad by forming a cut-out. This extraction allows the attachment portion to be accessible for flap attachment while the remaining pad structure maintains holding stability for the rest of the second torso portion.
2Manufacturing precision
If the side pad rotates to fit into the cut-out, then the flap attachment precision is improved, but the device complexity increases
Solution Approach 1:
The side pad is designed to rotate and fit into the cut-out of the second main pad, creating a nested configuration. This nesting mechanism achieves precise flap attachment by utilizing the existing cut-out structure rather than requiring a separate complex attachment mechanism.
Solution Approach 2:
The side pad is designed with rotational capability, transforming from a static structure to a dynamic one. This rotational motion allows the side pad to align and fit into the cut-out, achieving precise flap attachment through a simple rotational movement rather than complex positioning mechanisms.
3Productivity
If the main body is folded in two at the crotch portion, then the folding efficiency is improved, but the flap folding becomes more difficult
Solution Approach 1:
The main body is folded in two at the crotch portion before the flap folding operation. This preliminary action positions the main body in a configuration that facilitates subsequent flap folding, as the cut-out is already exposed and the side pad can rotate independently to attach the flap without interference from the main body folding operation.

AI summary
A device including: a main folding mechanism for folding a diaper body in two at the crotch portion by rotating first and second main pads having first and second holding surfaces, respectively; and a sub-folding mechanism for folding the flap by rotating a side pad having a sub-holding surface for holding the flap with respect to the first main pad, wherein; a cut-out is formed at a position corresponding to the attachment portion of the second main pad, wherein the cut-out does not allow the attachment portion to be held by the second main pad but instead expose the attachment portion; with the first and second holding surfaces being closed while opposing each other and with the main body folded in two, the cut-out allows the flap to be attached to the attachment portion; and the side pad rotates from a position where it is open while lying next to the first main pad in the girth direction to a position where the sub-holding surface is closed while opposing the first holding surface, fitting into the cut-out.
