Pet Diaper Elastic Member Erected Sections Waist Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable pet diapers often have ends that can turn up during application, leading to leakage issues when the pet excretes, as the liquid-permeable and liquid-resistant sheet ends may not stay in place effectively.
Innovation Solution
The disposable pet diaper incorporates a leakproof sheet stretchable elastic member that contracts to form erected sections, stabilizing the ends and ensuring a better fit around the pet's waist, preventing the ends from turning up and reducing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ends of the disposable pet diaper are made from liquid-permeable and liquid-resistant sheets, then the diaper provides effective liquid management and absorption, but the ends may turn up during application and fail to stay in place
Solution Approach 1:
The patent changes the physical state and mechanical properties of the end regions by incorporating stretchable elastic members and forming erected sections. This transforms the flexible sheet ends into structured, upright configurations that maintain their position and prevent turning up, thereby solving the position stability problem while preserving the liquid management function.
Solution Approach 2:
The patent introduces a vertical dimension by forming erected sections that extend upward from the horizontal plane of the diaper. This three-dimensional structure prevents the ends from turning up by creating a physical barrier that maintains contact with the pet's body, thus improving position stability without compromising the liquid-permeable and liquid-resistant properties.
2Ease of manufacture
If the diaper structure is simplified without stretchable elastic members, then the manufacturing process is easier and cost is reduced, but the ends cannot be stabilized and leakage occurs
Solution Approach 1:
The patent incorporates stretchable elastic members that can be integrated into existing manufacturing processes with minimal modification. These members change the mechanical parameters of the end regions, providing elasticity and contraction forces that stabilize the ends and prevent leakage, thus improving reliability without significantly complicating the manufacturing process.
Solution Approach 2:
The stretchable elastic members are pre-installed or pre-attached to the diaper structure during manufacturing, creating a ready-to-function system that requires no additional assembly steps by the user. This preliminary action ensures that the ends are stabilized from the moment of application, preventing leakage while maintaining ease of manufacture.
3Stability of the object's composition
If erected sections are formed using stretchable elastic members, then the ends are stabilized and fit around the pet's waist, but the device complexity increases
Solution Approach 1:
The patent uses stretchable elastic members to create erected sections that provide the necessary stability. While this adds some structural elements, the members are integrated into the existing diaper layers and require minimal additional components, thus achieving position stability with controlled increases in device complexity.
Solution Approach 2:
The stretchable elastic members serve multiple functions: they provide elasticity for fitting, create the erected section structure for stability, and maintain contact pressure for leakage prevention. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving the desired position stability.
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 solution effectively stabilizes the ends of the disposable pet diaper, ensuring a secure fit around the pet's waist and preventing excrement leakage by forming erected sections through the contraction of the leakproof sheet stretchable elastic member.
Implementation Method 1
a leakproof sheet stretchable elastic member disposed in a stretched state in the leakproof sheet
Implementation Method 2
while the disposable diaper is ready to be put on the pet, the leakproof sheet stretchable elastic member is already contracted so that the erected section is already formed

AI summary
To provide a disposable diaper for pets that fits well around the waist of the pet. A disposable diaper for pets, having: a rear- side waist area (130); a stomach-side waist area (110); a crotch area (120); both end sections (130Am, 110A) in the diaper longitudinal direction; both end sections (100A) in a diaper longitude-intersecting direction; a tail insertion opening (190); an absorbent core (200); an area (170) not having the absorbent core arranged therein; an attachment section (300) provided in the stomach-side waist area (110); an attachment area (900) that receives the attachment section (300); and an expandable/contractible elastic member (600) for a leakage-prevention sheet arranged, in an extended state, in the leakage-prevention sheet (800). The expandable/contractible elastic member (600) for the leakage-prevention sheet is arranged in a prescribed area in the diaper longitudinal direction, between the absorbent core (200) and the end section (100A) in the diaper longitude-intersecting direction. A standing-up section (700) in which the end section in the diaper longitudinal direction stands up is formed as a result of the contraction of the expandable/contractible elastic member (600) for the leakage-prevention sheet.
