Pet Diaper Erected Sections Prevent Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable pet diapers often experience issues with the ends of the waist areas turning up during application, leading to potential leakage when the pet excretes, as the liquid-permeable and liquid-resistant sheets can become misaligned, causing discomfort and inefficiency.
Innovation Solution
The design incorporates a leg stretchable elastic member that contracts to form erected sections on the ends of the diaper, stabilizing the shape and ensuring a secure fit around the pet's waist, with a waist stretchable elastic member forming waist gathers to maintain the absorbent core's position and prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the diaper ends are made from liquid-permeable and liquid-resistant sheets without additional support structures, then the diaper structure remains simple, but the ends turn up during application causing misalignment and potential leakage
Solution Approach 1:
The patent applies preliminary action by pre-forming erected sections at the diaper ends using elastic members before the diaper is put on the pet. These erected sections are created in advance to maintain the proper alignment of liquid-permeable and liquid-resistant sheets, preventing them from turning up during application and ensuring reliable leakage prevention from the start
Solution Approach 2:
The patent uses elastic members (such as elastic bands or stretchable fabrics) as flexible support structures to create erected sections at the diaper ends. These flexible elements conform to the pet's body shape while maintaining the structural integrity of the diaper ends, preventing sheet misalignment without adding rigid complex structures
2Shape
If elastic members are added to form erected sections at the diaper ends, then the shape stability and fit are improved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent applies parameter changes by utilizing the elastic properties of selected materials to automatically form erected sections when the diaper is stretched during application. By choosing materials with appropriate elastic moduli and stretch characteristics, the erected sections form through natural material behavior rather than complex mechanical assembly, simplifying the manufacturing process
Solution Approach 2:
The elastic members in the patent perform self-service by automatically forming and maintaining erected sections through their inherent elastic recovery. When the diaper is applied and stretched, the elastic members contract to create and sustain the erected sections without requiring external actuation or complex control mechanisms, reducing manufacturing complexity
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
This configuration ensures a snug and stable fit, preventing leakage by keeping the absorbent core aligned and the ends of the diaper in an erected state, effectively managing excretion and enhancing user convenience during application and wear.
Implementation Method 1
a leg stretchable elastic member which is arranged in a stretched state in a prescribed region extending in the diaper longitudinal direction between the absorbent core and each of the ends in the diaper transverse direction, and leg gathers formed by contraction of the leg stretchable elastic member, wherein each of the ends in the diaper longitudinal direction is erected by contraction of the leg stretchable elastic member and forms an erected section
Implementation Method 2
a waist stretchable elastic member forming waist gathers to maintain the absorbent core's position and prevent leakage

AI summary
A disposable diaper for pets includes: a back-side waist area; a stomach-side waist area; a crotch area; both end sections in the diaper longitudinal direction; both end sections in a diaper longitude-intersecting direction; a tail insertion opening; an absorbent core; an area not having the absorbent core arranged therein; an attachment section provided in the stomach-side waist area; an attachment area that accepts the attachment section; an expandable/contractible elastic member for legs, arranged, in the extended state, in a prescribed area in the diaper longitudinal direction, between the absorbent core and an end section in the diaper longitude-intersecting direction; a leg gather formed by the contraction of the expandable/contractible elastic member for legs; and a standing-up section in which the end sections in the diaper longitudinal direction stand up as a result of the contraction of the expandable/contractible elastic member for legs.
