Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing absorbent articles for pets, such as belly-wound articles, often require precise placement of the urethral opening between leakage-preventing gathers, which is difficult for users to achieve due to the need to look into the pet's urethral opening during application, leading to potential urine leakage.

Innovation Solution

The absorbent article features a pair of leakage-preventing gathers with at least one colored differently from the front surface sheet, allowing users to easily recognize their positions and ensure proper placement around the pet's urethral opening.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the absorbent article is designed with leakage-preventing gathers, then urine leakage is prevented, but it becomes difficult for users to recognize the correct placement position

Engineering Contradiction:

Improveurine leakage preventionVSAvoidplacement recognition

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent applies color changes by making at least a part of the leakage-preventing gathers a different color from the front surface sheet. This color differentiation enables users to easily recognize the position and extent of the gathers, ensuring correct placement of the absorbent article on the pet's body while maintaining the leakage-prevention function.

Inventive Principle:

Principle #32Color changes

2Reliability

If the absorbent article requires precise placement with gathers around the urethral opening, then absorption effectiveness is improved, but the application process becomes complex and time-consuming

Engineering Contradiction:

Improveabsorption effectivenessVSAvoidapplication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The color differentiation of the gathers provides immediate visual feedback to users during application, eliminating the need for careful inspection and adjustment to ensure correct placement. This reduces the time required for proper application while maintaining absorption effectiveness.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The colored gathers enable the absorbent article to guide its own correct placement through visual cues, reducing the need for user expertise or complex application procedures. The article essentially indicates its own proper position through the color-coded gathers.

Inventive Principle:

Principle #25Self-service

3Ease of manufacture

If the absorbent article uses a uniform color design, then manufacturing is simpler, but users cannot easily identify the front surface and gathers

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidorientation identification

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The patent uses color changes to differentiate the gathers from the front surface sheet, providing clear visual orientation cues for users. This minimal color differentiation maintains manufacturing simplicity while significantly improving ease of operation by enabling quick identification of the correct orientation and components.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

Instead of changing the color of the entire absorbent article, the patent applies local quality by coloring only specific parts (the gathers) differently. This approach maintains overall manufacturing simplicity while providing sufficient visual information for correct identification and placement.

Inventive Principle:

Principle #3Local quality

AI summary

An absorbent article for a pet according to one aspect is an absorbent article for a pet that is wound around a body of a pet to be worn. The absorbent article includes a body portion having a laterally long shape having a longitudinal direction and a lateral direction. The body portion includes a front surface sheet disposed on a skin surface side, a back surface sheet disposed on a non-skin surface side, an absorber disposed between the front surface sheet and the back surface sheet, and a pair of leakage-preventing gathers disposed outside the absorber in the lateral direction. At least a part of one or both of the pair of leakage-preventing gathers is colored in a color different from the front surface sheet.
