Pet Diaper Elastic Member Intersection for Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable pet diapers often experience issues with the ends turning up during application, leading to potential leakage 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 design incorporates a leg stretchable elastic member and a waist stretchable elastic member that are contracted to form intersecting contraction forces, stabilizing the ends and ensuring a secure fit around the pet's waist, with the absorbent core positioned to manage excretion weight and prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ends of the diaper are made simple without elastic members, then the device complexity is reduced, but the ends turn up during application and cause leakage
Solution Approach 1:
The patent applies parameter changes by introducing stretchable elastic members that alter the physical state of the diaper ends from rigid to flexible. The elastic members change the mechanical properties of the ends, enabling them to stretch and conform to the pet's body contours, thereby preventing turning up and leakage while maintaining a relatively simple overall structure.
Solution Approach 2:
The patent implements dynamics by making the diaper ends dynamic rather than static. The stretchable elastic members allow the ends to adapt and move with the pet's body movements, maintaining continuous contact and seal integrity. This dynamic characteristic prevents the ends from turning up during application and use, solving the leakage problem without requiring complex rigid structures.
2Stability of the object's composition
If stretchable elastic members are added to stabilize the ends, then the fit security is improved, but the device complexity increases
Solution Approach 1:
The patent applies local quality by placing stretchable elastic members specifically at the ends of the diaper where stability is needed, rather than throughout the entire diaper structure. This localized approach provides the necessary end stability to prevent turning up and leakage while keeping the rest of the diaper structure simple and easy to manufacture.
Solution Approach 2:
The patent uses partial action by implementing elastic members only at the critical ends of the diaper rather than throughout the entire structure. This partial application of elasticity provides sufficient stabilization where needed (at the ends) without the excessive complexity that would result from making the entire diaper elastic, thus achieving stable end positioning with minimal added complexity.
