Hook-and-Loop Fastener for Removable Ceramic Tile Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for fixing ceramic tiles using cement-based adhesives create a permanent bond, making it difficult to remove tiles without damaging the underlying surface, which discourages frequent decoration of tiled areas due to mess, perceived permanence, skill requirements, and complexity in choosing and applying adhesives.
Innovation Solution
A wall surface covering system utilizing a hook-and-loop fastener system with microscopic, tightly-packed mushroom-shaped hooks and lightweight knitted loops, providing a balance of high pull and shear strength with low peel strength to securely fix and easily remove ceramic tiles without damaging the wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If cement-based adhesives are used to fix ceramic tiles, then the tiles are securely fixed to the wall, but the bond becomes permanent and difficult to remove without damaging the underlying surface
Solution Approach 1:
The patent applies a dynamic fastening system using hook-and-loop fasteners that can transition between engaged (fixed) and disengaged (removed) states. This dynamic mechanism allows the tile covering to be securely fixed during use but easily removed when needed, resolving the contradiction between permanent bond strength and ease of removal.
Solution Approach 2:
The fastening system is segmented into two separate components: a hook component attached to the wall surface covering and a loop component attached to the tile back. This segmentation allows independent optimization of each component's properties and enables the tile to be removed by simply separating the two components, eliminating the need for damaging removal processes.
2Reliability
If traditional tiling methods are used, then tiles are firmly attached to the wall, but the process creates mess and requires skilled tradesmen
Solution Approach 1:
The patent replaces the chemical bonding mechanism of cement-based adhesives with a mechanical fastening system using hook-and-loop fasteners. This substitution eliminates the mess associated with mixing and applying wet adhesives, removes the need for specialized tools, and allows unskilled individuals to install tiles by simply pressing them into place.
Solution Approach 2:
The hook component of the fastening system is designed as a disposable element that remains attached to the wall surface. This allows the expensive tile and loop component to be reused while the cheaper hook component is discarded, simplifying the installation process and reducing overall system complexity.
3Ease of operation
If hook-and-loop fasteners are used to enable easy removal, then tiles can be removed without damage, but the bond strength may be insufficient to securely hold the tiles
Solution Approach 1:
The patent optimizes the parameters of the hook-and-loop fastening system, specifically the hook density, loop density, and engagement depth, to achieve the desired balance between bond strength and ease of removal. By carefully controlling these parameters, the system provides sufficient holding strength for secure attachment while maintaining low removal force requirements.
Solution Approach 2:
The fastening system employs different local densities and configurations of hooks and loops in different areas to optimize performance. The hook component features densely packed microscopic hooks for strong engagement, while the loop component uses lightweight knitted loops that provide sufficient holding force but can be easily pulled apart, creating local variations in fastening strength.
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
Enables secure fixation and easy removal of ceramic tiles, reducing installation and removal complexity, eliminating mess, and allowing for more frequent decoration without damaging the surface, while being cost-effective and suitable for various tile sizes.
Implementation Method 1
a first component of a hook-and-loop fastener fixable to the rigid body of the wall surface covering; and a second component of the hook-and-loop fastener that is fixable to the underlying vertical surface. The first and second components are cooperable such that, when the first component is fixed to the surface covering and the second component is fixed to the underlying vertical surface, the first and second components can be engaged to cause the wall surface covering to grip the wall.
Implementation Method 2
the hooks of a hook component of the hook-and-loop fastener are microscopic, tightly-packed and comprise a stem and a cap, the cap extending beyond the stem in all directions to engage the loop fastening bi-directionally

AI summary
A wall surface covering system comprising: a wall surface covering for covering an underlying vertical support surface constituted by a wall, said wall surface covering comprising a rigid body; a first component of a hook-and-loop fastener fixable to the rigid body of the wall surface covering; and a second component of the hook-and-loop fastener that is fixable to the underlying vertical surface. The first and second components are cooperable such that,when the first component is fixed to the surface covering and the second component is fixed to the underlying vertical surface, the first and second components can be engaged to cause the wall surface covering to grip the wall. The first and second components are configured to cooperate to provide a fastening having a pull strength and a shear strength that are high enough to hold the surface covering in position on the vertical support surface, and a peel strength that is low enough to allow removal of the surface covering from the underlying surface by peeling the rigid body away from the wall.
