Ceramic Tile Bending with Refractory Strip Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for bending ceramic tiles face issues with the filling material dripping or sticking to the support during heating, leading to production inefficiencies and strength compromises in the final product.
Innovation Solution
A flexible refractory strip, such as a wool-based insulating paper strip, is applied over the grooves filled with a compatible material, anchoring it to the tile to prevent material loss and sticking, allowing the tile to bend without compromising the strip's integrity, and is removed after the bending process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the filling material is melted and integrated with the tile material during heating, then the tensile and compressive strength of the deformed area is increased, but the filling material may drip out of the grooves or stick to the support
Solution Approach 1:
The grooves are pre-filled with compatible material before heating, and the tile is pre-positioned on the shaped support before the softening stage. This preliminary preparation ensures that when the filling material melts during heating, it remains contained within the grooves and properly integrated with the tile structure, preventing both dripping loss and sticking to the support
Solution Approach 2:
A release agent or barrier layer is introduced between the filling material and the support surface. This intermediary prevents direct adhesion between the melted filling material and the support, allowing the material to integrate with the tile while avoiding sticking problems during the heating and softening process
2Stability of the object's composition
If the filling material is melted during heating, then it integrates intimately with the tile material strengthening the deformed area, but it may get stuck to the support causing production problems
Solution Approach 1:
A release agent or barrier layer is introduced between the filling material and the support surface. This intermediary prevents direct adhesion between the melted filling material and the support, allowing the material to integrate with the tile while avoiding sticking problems during the heating and softening process
Solution Approach 2:
The heating parameters are carefully controlled to achieve complete integration of the filling material with the tile material while maintaining a temperature profile that prevents excessive melting or sticking. The heating is applied selectively to the area containing the grooves and filling material, ensuring proper integration without causing the material to stick to the support
3Shape
If the tile is heated to the softening temperature for deformation, then the tile can be bent into special shapes, but the filling material may drip or stick during this process
Solution Approach 1:
The grooves are pre-filled with compatible material before heating, and the tile is pre-positioned on the shaped support before the softening stage. This preliminary preparation ensures that when the filling material melts during heating, it remains contained within the grooves and properly integrated with the tile structure, preventing both dripping loss and sticking to the support
Solution Approach 2:
A release agent or barrier layer is introduced between the filling material and the support surface. This intermediary prevents direct adhesion between the melted filling material and the support, allowing the material to integrate with the tile while avoiding sticking problems during the heating and softening process
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
This method ensures strong, shaped ceramic parts with improved production efficiency by preventing material loss and maintaining the tile's structural integrity, while maintaining the advantages of increased strength and resemblance to standard tiles.
Implementation Method 1
a flexible strip made with an incombustible refractory material up to at least the softening temperature of the tile; this flexible strip is preferably a wool-based insulating paper strip
Implementation Method 2
heating, at least in the area of the tile in which the grooves are obtained filled with the filling material and that is to be bent, up to the softening temperature of the area itself. In this stage, the filling material is also softened and integrates intimately with the material of which the tile is made
Implementation Method 3
The strip is then anchored to the surface of the tile on which the grooves are obtained. For that purpose, adhesion of the strip to the filling material which is normally a sticky paste may be sufficient

AI summary
The invention relates to an improved method for bending ceramic tiles. The method comprises the stages of making grooves in the lower surface of the tile in the area of the tile to be bent, filling the grooves obtained on the tile with a filling material compatible with the material of which the tile is made, covering the grooves with a flexible strip of incombustible refractory- material, anchoring the strip to the surface of the tile, heating the area of the tile to be bent up to the softening temperature of the area itself and cooling the modelled tile thus obtained.
