Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to effectively protect surfaces from various debris and secretions, particularly from pets, while also being easy to clean and reusable.
Innovation Solution
A multilayer cover comprising a first layer with a natural static charge to attract debris and a second layer with a hydrophobic laminate to repel moisture, combined with a hydrophilic coating for easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-layer cover is used, then the structure is simple, but it cannot simultaneously attract debris and repel moisture
Solution Approach 1:
The cover is divided into multiple layers, each performing a specific function: the first layer with static charge attracts and holds debris, while the second layer with hydrophobic properties repels moisture. This segmentation allows each layer to specialize in one protective function, resolving the contradiction between structural simplicity and effective multi-hazard protection.
Solution Approach 2:
The cover combines different materials with complementary properties: a textile material with natural static charge for debris attraction, and a hydrophobic laminate for moisture repulsion. This composite structure integrates multiple protective functions into a single cover system, achieving both debris trapping and liquid protection simultaneously.
2Object-affected harmful factors
If a hydrophobic laminate is added to repel moisture, then liquid protection is improved, but the cover becomes harder to clean
Solution Approach 1:
The hydrophobic laminate is designed with specific material properties that allow it to repel liquids while still permitting debris to be removed. The laminate's selective permeability and surface properties enable liquid rejection while maintaining ease of cleaning through standard washing processes, resolving the contradiction between liquid protection and cleaning ease.
3Object-affected harmful factors
If a static charge is used to attract debris, then debris trapping is improved, but the cover accumulates static engagement with surfaces
Solution Approach 1:
The cover is segmented into functional layers where the static charge is confined to the first layer for debris attraction, while the second layer provides a non-static interface with surfaces. This segmentation isolates the static charge to its useful function while preventing unwanted static engagement with underlying surfaces.
Solution Approach 2:
The hydrophobic laminate acts as an intermediary layer between the statically charged first layer and the surface. It mediates the interaction by providing a non-static barrier that prevents unwanted static engagement while allowing the static charge in the first layer to effectively trap debris.
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 cover effectively traps and releases debris, prevents liquid from reaching the surface, and is easy to clean and reuse, providing effective protection for surfaces from pet debris and secretions.
Implementation Method 1
a first layer having a first surface configured to attract debris, wherein the first surface is coated with a material configured to be antimicrobial, stain resistant, and/or odor resistant
Implementation Method 2
a second top surface including a laminate, the second top surface being in contact with the first bottom surface, the second top surface being hydrophobic and configured to repel moisture that passes through the first layer
Implementation Method 3
a textile cover having a surface finish with hydrophilic properties for absorbing liquids, and a cleaning property for interacting with the absorbed liquid

AI summary
A multilayer cover designed to protect a surface from pets includes a first layer constructed from a polyester material and a second layer coupled to the first layer. The second layer is fixed relative to the first layer. The first layer includes a first top surface having a natural charge and a hydrophilic finish. The natural charge configured to attract solid debris, and the hydrophilic finish configured to activate when contacted by a liquid in order to release the solid debris. The first layer also includes a first bottom surface positioned opposite to the first top surface. The second layer includes a second top surface disposed facing the first bottom surface. The second top surface includes a hydrophobic laminate. A second bottom surface is disposed opposite of the second top surface. The hydrophobic laminate is configured to block liquid from reaching the second bottom surface.
