Pet Absorbent Article Solid Gather Stiffness Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional absorbent articles for pets, particularly those with urethral openings positioned forward, face issues with urine leakage due to inward tilting of solid gathers and physical stress on the pet's urinary organs when the shorter backside gather is in contact with the sex organ.
Innovation Solution
An absorbent article design featuring a rectangular shape with a first solid gather portion that lies outward and a second solid gather portion that lies inward, both equipped with elastic members and high stiffness regions, ensuring proper coverage of the urinary organ without physical stress, and including a position mark for easy application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the upright part of the solid gather positioned on the back side of the pet's body is made shorter to prevent urine leakage, then urine leakage is prevented, but the solid gather easily inclines inward during putting on the pet, causing the solid gather to no longer cover the back side of the pet's urinary organ and urine may leak
Solution Approach 1:
The patent applies parameter changes by modifying the stiffness characteristic of the solid gather portion. Specifically, the solid gather portion is designed with higher stiffness than conventional designs, which changes the physical parameter of rigidity. This stiffness modification prevents the solid gather from inclining inward during use, maintaining its position to cover the urinary organ while still preventing urine leakage through the shortened upright part design.
2Reliability
If the upright part of the solid gather positioned on the back side of the pet's body is made shorter to prevent urine leakage, then urine leakage is prevented, but an intense stress is applied to the base of the pet's sex organ and the pet may be physically stressed
Solution Approach 1:
The patent applies local quality by creating different stiffness characteristics in different portions of the absorbent article. The solid gather portion is designed with higher stiffness to maintain position and prevent urine leakage, while other portions maintain normal flexibility. This localized stiffness modification allows the solid gather to fulfill its protective function without transmitting intense stress to the pet's urinary organ, as the stiffness is concentrated only where needed for position maintenance.
3Reliability
If the absorbent article is designed with solid gathers that can cover the urinary organ, then urine leakage is prevented, but the solid gather may incline inward during use, reducing coverage and causing leakage
Solution Approach 1:
The patent modifies the stiffness parameter of the solid gather portion to higher values compared to conventional designs. This parameter change ensures that once the solid gather is positioned to cover the urinary organ, it maintains this position reliably during use. The increased stiffness reduces the tendency to incline inward, making the positioning more stable and reducing the need for continuous adjustment during the pet's normal activities.
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
The design effectively prevents urine leakage and reduces physical stress on the pet by ensuring the solid gathers maintain their position to cover the urinary organ appropriately, even for pets with urethral openings forward of the hind leg base.
Implementation Method 1
an elastic member that is attached to a vicinity of an inner edge side of the pair of side sheets
Implementation Method 2
an absorbent core disposed between the top surface layer and the back surface layer
