V-Shaped Rug Corner Weight for Curling and Slip Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Area rug corners tend to curl upward over time, causing both aesthetic issues and safety hazards due to tripping risks, especially in commercial settings.
Innovation Solution
A V-shaped apparatus with a planar top and bottom, an adhesive layer, and a removable protective cover is applied to the rug corner to maintain it flat, featuring a laminate structure with an elastomeric and plastic layer for anti-slip protection and a hook-and-pile fastener option for easy removal and washing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rug corner is left without any device, then the rug maintains its original flexibility and comfort, but the rug corner curls upward causing safety hazards and aesthetic issues
Solution Approach 1:
The patent introduces a corner weight device as an intermediary object between the rug corner and the floor. This device consists of a V-shaped body with adhesive layers that attach to the rug corner, providing downward force to counteract the curling tendency and keep the rug corner flat on the floor surface.
Solution Approach 2:
The patent changes the physical state of the rug corner by applying a weight device that exerts downward force. The adhesive layers transform the temporary attachment into a stable bond, while the weight provides continuous downward pressure to maintain the rug corner in a flat state, effectively changing its position parameter.
2Reliability
If a corner weight device is applied to prevent curling, then the rug corner remains flat and safe, but the device adds complexity to the rug maintenance
Solution Approach 1:
The corner weight device is segmented into distinct functional components: a V-shaped body for structural support, adhesive layers for attachment, and a protective cover for the adhesive. This segmentation allows each component to perform its specific function efficiently and simplifies the overall maintenance process.
Solution Approach 2:
The adhesive layers are designed as consumable components that can be replaced when they lose effectiveness. The protective cover can be removed and discarded after use, allowing the adhesive to be reapplied. This approach reduces maintenance complexity by replacing simple, inexpensive components rather than servicing a complex integrated system.
3Reliability
If adhesive is applied to secure the device to the rug, then the device stays in place effectively, but the adhesive may damage the rug fabric or floor surface
Solution Approach 1:
The patent uses removable adhesive materials that change their bonding characteristics based on environmental conditions such as temperature and pressure. The adhesive provides strong initial bonding to secure the device, but can be removed or softened with heat or solvent application to prevent permanent damage to the rug or floor surface.
Solution Approach 2:
The protective cover acts as a thin film that protects the adhesive layer from direct contact with the rug or floor during installation. This cover can be peeled away to reveal the adhesive, which then bonds the device to the rug corner without the cover interfering with the bonding process or causing damage.
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
Effectively prevents rug corner curling, providing anti-slip protection and ensuring the rug lies flat, thereby enhancing safety and appearance while allowing for easy maintenance.
Implementation Method 1
An adhesive layer is applied to at least a portion of the top of the body
Implementation Method 2
an elastomeric layer adapted to abut against a floor surface and, in doing so, prevents slippage between the apparatus and the floor surface
Implementation Method 3
the V-shaped body is removably secured to the bottom of the rug by hook-and-pile fasteners

AI summary
An apparatus to prevent curling of a rug corner. The apparatus includes a rigid and planar V-shaped body having a top surface and a bottom surface. A hook-and-pile fastener detachably secures the body and rug together. The body maintains the rug corner in a flat condition thus preventing any curling of the rug.
