Solution Overview

Problem

Conventional absorbent pads with hook tapes require significant space and force for removal, leading to troublesome replacement and potential damage to diapers or lower-body underwear due to shearing forces.

Innovation Solution

An absorbent pad design featuring a folded attachment panel with hook tape projections exposed on the outer surface, allowing for orthogonal detachment without shearing force, reducing the need for strong pulling and minimizing damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the hook tape is used to attach the absorbent pad to the diaper or lower-body underwear, then the displacement prevention capability is improved, but the removal process becomes difficult and may cause damage to the diaper or lower-body underwear

Engineering Contradiction:
Improvedisplacement prevention capabilityVSAvoidremoval process
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The attachment panel is divided into a base portion and an extended portion that can be separated during removal. The extended portion with hook tape can be detached from the base portion, allowing the hook tape to be removed without pulling on the entire absorbent pad and causing damage to the diaper or lower-body underwear.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hook tape is extracted as a separate removable component on the extended portion of the attachment panel. This allows the hook tape to be taken out and removed from the diaper or lower-body underwear without damaging the underlying fabric, while the base portion remains attached to the absorbent pad.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If the diaper or lower-body underwear is pulled down significantly for removal, then the absorbent pad can be removed, but the replacement process becomes troublesome and requires significant space

Engineering Contradiction:
Improveabsorbent pad removalVSAvoidreplacement process time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The extended portion with hook tape is pre-configured to extend beyond the absorbent pad boundaries, allowing the user to grasp and pull the extended portion for removal without needing to pull down the entire diaper or lower-body underwear. This preliminary configuration enables easy removal in place.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the hook tape adhesive power is weakened to reduce detachment force, then the removal becomes easier, but the displacement prevention capability is reduced

Engineering Contradiction:
Improvedetachment forceVSAvoiddisplacement prevention capability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The attachment system is segmented into a base portion for strong attachment and an extended portion with hook tape for easy removal. This segmentation allows the base portion to maintain strong adhesive power for displacement prevention while the extended portion enables easy detachment without requiring weakened adhesive throughout.

Inventive Principle:
Principle #1Segmentation

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables easy and damage-free removal of absorbent pads from diapers or lower-body underwear, maintaining displacement prevention capability without weakening the adhesive power of the hook tape.

Implementation Method 1

a hook tape that is fixed to the extended portion on a surface thereof which is the same side as the surface of the base portion fixed to the absorbent pad and that has a large number of hook shaped projections on an opposite of the fixed surface

AI summary

The invention provides an absorbent pad which can be easily peeled from a diaper or underwear for the lower part of the body. The absorbent pad (200) has, on the back side of an outer sheet (25), an attachment panel (31) which is sectioned into an extending portion (31 a) bearing a hook tape (32) on the face side and a base end portion (31 b) fixed to the outer sheet (25) with a folding-back area (31 c) between both portions (31 a) and (31 b), whereby the hook tape (32) can be exposed to the outer surface of the pad (200) by bending the attachment panel (31) along the folding-back area (31 c) in such a way as to lay the extending portion (31 a) on the base end portion (31 b).
