Pet Pad with Detachable Liquid Permeable Sheet for Urine Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pet pads do not have a built-in function to receive pet urine, and existing potty pads lack a cushion function, often slipping off when pets play or roll, making cleanup and urine absorption inefficient.
Innovation Solution
A pet pad design featuring a pad body with a liquid permeable sheet body, including a fixing segment and a positioning segment, allowing a moisture-absorbing sheet to be easily placed and sandwiched between the two for effective urine absorption and cushioning, with a mesh-like structure to prevent slipping and facilitate easy sheet replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a potty pad is placed on the pet pad to receive urine, then urine absorption function is improved, but the potty pad slips off when the pet plays or rolls
Solution Approach 1:
The liquid permeable sheet body is divided into three functional segments: a liquid permeable portion for urine absorption, a fixing segment that is permanently fixed to the pad body, and a positioning segment that is detachably positioned on the mating portion. This segmentation allows the pad to provide both urine absorption and stable positioning simultaneously, resolving the contradiction between absorption capacity and position stability.
Solution Approach 2:
The positioning segment is nested within the mating portion of the pad body, creating an interlocking structure. The annular portion of the liquid permeable sheet body is inserted into the mating portion, with the positioning segment fitting into the mating portion's recesses. This nesting structure prevents the potty pad from slipping off while allowing easy installation and removal, thus improving both position stability and urine absorption function.
2Quantity of substance
If a moisture absorbing sheet body is placed between the liquid permeable sheet body and the pad body, then urine absorption is improved, but the sheet body is difficult to remove and replace
Solution Approach 1:
The liquid permeable sheet body is segmented into a fixing segment and a positioning segment. The positioning segment is detachably positioned on the mating portion, creating an opening that provides access to the moisture absorbing sheet body. This segmentation allows users to easily remove and replace the moisture absorbing sheet body without having to remove the entire liquid permeable sheet body, thus improving ease of operation while maintaining urine absorption capacity.
Solution Approach 2:
The positioning segment acts as an intermediary structure between the liquid permeable sheet body and the pad body. It provides a detachable connection that allows the moisture absorbing sheet body to be accessed, removed, and replaced conveniently. The positioning segment's detachable positioning on the mating portion creates an opening that serves as an access pathway, making sheet replacement easy while maintaining the structural integrity needed for urine absorption.
3Reliability
If the liquid permeable sheet body is fully fixed to the pad body, then position stability is improved, but the moisture absorbing sheet body cannot be accessed for replacement
Solution Approach 1:
The liquid permeable sheet body is divided into a fixing segment and a positioning segment with different attachment characteristics. The fixing segment is fully fixed to the pad body to ensure position stability and prevent slipping. The positioning segment is detachably positioned on the mating portion, providing controlled access to the moisture absorbing sheet body. This segmentation resolves the contradiction by providing both stability and accessibility.
Solution Approach 2:
Different portions of the liquid permeable sheet body have different attachment qualities: the fixing segment has permanent fixation for stability, while the positioning segment has detachable positioning for accessibility. This local differentiation of attachment properties allows the pad to simultaneously achieve position stability and ease of sheet replacement, resolving the contradiction between these two requirements.
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

AI summary
A pet pad includes a pad body and a liquid permeable sheet body. The pad body is sheet shaped and has a carrying surface. The carrying surface has a mating portion. The liquid permeable sheet body has a liquid permeable portion and an annular portion circumferentially connected to a periphery of the liquid permeable portion. The annular portion includes a fixing segment and a positioning segment. The fixing segment is fixed to the carrying surface, the positioning segment is detachably positioned on the mating portion, and a length of the fixing segment is greater than a length of the positioning segment. The positioning segment is capable of being separated from the mating portion to form an opening, and the pet pad is configured to provide a moisture absorbing sheet body to be placed between the liquid permeable sheet body and the pad body through the opening.
