Releasable Adhesive Sheet for Ceramic Tile Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceramic tiles are difficult to remove and replace from floors without damaging the underlying substrate, as existing solutions either require permanent adhesion that can damage hardwood floors or are not suitable for all types of substrates, such as concrete and wood.
Innovation Solution
A pre-fabricated article comprising a backer board with a releasable adhesive sheet that allows ceramic tiles to be easily and quickly removed by peeling the sheet from the backer board, using a floating vinyl sheet or adhesive tape that provides stability without permanent bonding, enabling easy installation and removal on various substrates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If ceramic tiles are permanently bonded to the substrate using conventional adhesive methods, then the tiles have strong attachment and stability, but the tiles become difficult to remove and may damage the underlying substrate
Solution Approach 1:
The adhesive system is segmented into two distinct components: a permanent adhesive that bonds the backer board to the substrate, and a releasable adhesive that bonds the vinyl sheet to the backer board. This segmentation allows the tile assembly to be strongly attached during installation while enabling easy removal later by peeling off the vinyl sheet, thus resolving the contradiction between strong attachment and ease of removal
Solution Approach 2:
The vinyl sheet acts as an intermediary layer between the ceramic tiles and the substrate. It provides a bonding surface for the tiles while being releasably attached to the backer board. This intermediary enables the tiles to be securely held during use but easily removed when needed, without damaging the underlying substrate
2Strength
If backer board is attached to hardwood floor using screws, nails, or conventional adhesive, then the floor gains sufficient strength to support ceramic tiles, but the hardwood floor may be damaged
Solution Approach 1:
The vinyl sheet serves as a protective intermediary between the ceramic tiles and the hardwood floor. It is releasably bonded to the backer board, allowing the tile assembly to be installed on floors with sufficient strength while enabling removal without damaging the hardwood surface. The releasable adhesive ensures the bond is strong enough for support but gentle enough for safe removal
3Strength
If conventional adhesive is used to bond vinyl sheet to backer board, then strong bonding is achieved, but the tiles cannot be easily removed for replacement
Solution Approach 1:
The adhesive properties are changed by using a releasable adhesive with specific chemical or physical parameters that allow it to form a bond strong enough to hold the vinyl sheet and tiles in place during normal use, but that can be easily reversed or broken under controlled removal conditions. This parameter change enables both strong bonding and easy replacement

AI summary
An article for applying to a floor substrate for preparing the floor substrate for laying of ceramic tiles by bonding ceramic tiles to the article. The article comprises a backer board having a lower surface for application to a floor substrate and an upper surface, a sheet, and a releasable adhesive bonding the sheet to the upper surface of the backer board. The sheet covers the entirety of the upper surface of the backer board. After the article is applied to the floor substrate, ceramic tiles are then bonded to the sheet. For replacement of the ceramic floor, the releasable adhesive allows the sheet with the ceramic tiles attached to be easily removable from the backer board. A method for laying ceramic tiles comprising laying at least one sheet on a floor substrate so that it floats on the floor substrate, and bonding a plurality of ceramic tiles to the at least one sheet.
