Pet Bed Absorbent Sheet Anti-Leakage Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pet beds with fabric covers allow liquid excreta or washing fluids to permeate and foul the frame or block body, leading to hygiene issues, and absorbent sheets can cause leakage due to diffusion over the pet's body or sheet surface.
Innovation Solution
A pet bed design featuring a frame body with a cushioned mat and an absorbent sheet on top, where the absorbent sheet has a larger expanded area than the mat, forming standing sections against the frame to prevent leakage, and includes a liquid-permeable cushion material with specific fiber structures for stability and spacing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fabric cover is used on the pet bed, then the bed can be removed and washed for hygiene, but liquid excreta or washing fluids permeate through the cover and foul the frame member or block body
Solution Approach 1:
The patent implements a nested structure where the absorbent sheet is placed inside the cover, which itself is nested within the frame body. This nested arrangement allows the absorbent sheet to intercept liquids before they reach the frame member or block body, while the cover remains removable for washing. The absorbent sheet acts as an inner layer that contains liquids, preventing them from penetrating through the cover to foul underlying components.
2Object-affected harmful factors
If an absorbent sheet is spread over the bed to prevent fouling, then liquid absorption is improved, but the liquid diffuses over the surface causing leakage from the absorbent sheet
Solution Approach 1:
The patent employs the cover as a flexible shell that contains the absorbent sheet and provides structural confinement. The cover's walls rise along the inner peripheral wall surfaces of the frame body, creating a contained environment that prevents liquid diffusion beyond the absorbent sheet's boundaries. This flexible shell structure maintains the absorbent sheet in position while preventing leakage by confining liquids within the cover's enclosure.
Solution Approach 2:
The patent transitions from a two-dimensional absorbent sheet to a three-dimensional contained structure by utilizing the cover's vertical walls. The cover extends upward along the inner peripheral wall surfaces, creating a vertical dimension that forms anti-leakage walls. This dimensional transformation prevents liquid from spreading horizontally across the surface by providing vertical containment boundaries.
3Shape
If the absorbent sheet has the same area as the mat surface, then it fits neatly, but liquid can leak from the edges of the sheet
Solution Approach 1:
The patent creates an asymmetric relationship between the absorbent sheet and the cover. The absorbent sheet has a planar area smaller than the cover's inner peripheral surface area, allowing the cover to extend beyond the sheet's edges. This asymmetry enables the cover to form anti-leakage walls that rise vertically along the inner peripheral wall surfaces, containing liquids within the cover's boundaries while the absorbent sheet remains properly positioned on the mat surface.
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 design effectively absorbs and retains liquids, preventing fouling and maintaining hygiene by forming anti-leakage walls and ensuring stable absorbency even under pet pressure.
Implementation Method 1
the absorbent sheet has a planar area in the expanded state that is larger than the planar area of the top surface of the mat... the liquid of the liquid excreta or washing fluid can be absorbed and retained in the absorbent sheet
Implementation Method 2
the outer perimeter edges of the absorbent sheet rise toward the top side along the inner peripheral wall surfaces of the frame body, allowing formation of standing sections that function as anti-leakage walls against the aforementioned liquid
