Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pet urinal mats fail to absorb large volumes of pet urine efficiently, leading to side leakage issues due to inadequate absorption capacity.
Innovation Solution
A stratiform pet urinal pad design featuring a non-woven fabric coating layer, a fast absorbing layer, a mixed absorbing layer with increased thickness at the periphery, a PE film leakage prevention layer, and a toilet paper absorbing layer, which forms a recess structure to prevent side leakage and enhance urine retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional absorbing layer is used, then the structure is simple, but side leakage occurs when large volume of urine is present
Solution Approach 1:
The absorbing layer is segmented into two distinct parts: a fast absorbing layer in the middle and a mixed absorbing layer at the periphery. This segmentation allows each part to perform its specific function - the fast absorbing layer quickly absorbs urine from the center, while the thicker mixed absorbing layer at the edges prevents side leakage by containing urine that moves outward.
Solution Approach 2:
Different regions of the absorbing layer are given different properties. The periphery region has a larger thickness and uses mixed absorbing material, while the center region uses fast absorbing material. This local differentiation ensures that the periphery is optimized for containment and slow absorption, while the center is optimized for rapid absorption.
2Reliability
If the absorbing layer thickness is increased throughout, then side leakage is prevented, but the absorption speed decreases
Solution Approach 1:
The patent applies local quality by making the absorbing layer thickness position-dependent. The periphery region has increased thickness for containment, while the center region maintains optimal thickness for fast absorption. This resolves the contradiction by optimizing each region's thickness for its specific function rather than uniformly increasing thickness throughout.
Solution Approach 2:
By segmenting the absorbing layer into periphery and center regions with different thicknesses and material compositions, the patent enables the periphery to provide leakage prevention through increased thickness while the center maintains fast absorption capability through optimized thickness and material selection.
3Duration of action of moving object
If a single absorbing layer is used, then the device is simple, but urine is not retained long enough for complete absorption
Solution Approach 1:
The absorbing layer is divided into two functional segments: the fast absorbing layer for rapid initial absorption and the mixed absorbing layer for sustained absorption and containment. This segmentation extends the overall absorption duration by providing both quick action and prolonged retention capabilities.
Solution Approach 2:
The patent uses composite absorbing materials with different properties in different regions. The fast absorbing layer uses materials optimized for rapid absorption, while the mixed absorbing layer combines materials that provide both absorption and structural containment, extending the duration of effective urine retention.

AI summary
A fast absorption side leakage-prevention pet urinal pad includes a urinal pad body that includes a stratiform structure, wherein the urinal pad body includes a non-woven fabric coating layer; an absorbing layer below the coating layer; and a PE film leakage-prevention layer below the absorbing layer; wherein a toilet paper absorbing layer is also arranged between the PE film leakage-prevention layer and the absorbing layer, wherein the absorbing layer comprises two parts: a fast absorbing layer in the middle of the urinal pad body and a mixed absorbing layer at the periphery of the fast absorbing layer, wherein a thickness of the urinal pad body at a location corresponding to the mixed absorbing layer is larger than the thickness of the urinal pad body at a location corresponding to the fast absorbing layer, thereby a recess structure is formed on the surface of the urinal pad body.
