Bead Polymer Adhesive Tape for Residue-Free Wall Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double-sided adhesive tapes struggle to remove objects from walls without leaving residues or damaging sensitive wall substrates, such as painted or wallpapered walls, while also being visually concealed during application.
Innovation Solution
A double-sided adhesive tape with a carrier material comprising foam and a second adhesive made of bead polymers, allowing for residue-free and damage-free removal by twisting, prying, or peeling, while remaining concealed during application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adhesive tape is used to affix objects to walls, then objects can be easily mounted, but removal may damage sensitive wall substrates such as painted or wallpapered walls
Solution Approach 1:
The adhesive composition is changed from conventional adhesive to bead polymers, which fundamentally alters the adhesion mechanism. Bead polymers form discrete spherical structures that create mechanical interlocking with the wall surface while maintaining ease of application, yet allow for clean removal without damaging sensitive substrates like painted or wallpapered walls
Solution Approach 2:
The adhesive tape employs a composite structure combining a foam carrier material with bead polymer adhesive. This composite design integrates the structural support function of the foam carrier with the controlled adhesion properties of bead polymers, achieving both easy mounting and damage-free removal on sensitive wall surfaces
2Ease of operation
If adhesive tape protrudes beyond the edge of the object to enable removal pulling, then removal is possible, but the adhesive tape becomes visible which is undesirable
Solution Approach 1:
The removal mechanism is inverted from the conventional approach. Instead of requiring parallel pulling motion that needs tape protrusion, the invention enables removal by twisting or prying motions that can be applied at the edge of the object. This allows the tape to remain fully concealed while still enabling effective removal
Solution Approach 2:
The removal action transitions from a two-dimensional parallel pulling motion to a three-dimensional twisting or prying motion. This dimensional change allows removal to be initiated at the edge of the object without requiring the tape to protrude beyond the object edges, keeping the tape concealed during both application and removal
3Ease of operation
If conventional adhesive tape is stretched for removal, then tape can be removed, but residues may remain on the wall
Solution Approach 1:
The adhesive material is changed from conventional continuous adhesive to bead polymers with discrete spherical structures. This parameter change in adhesive architecture allows the adhesive to maintain strong bonding during application but release cleanly during removal by twisting or prying, leaving no residues on the wall surface
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 adhesive tape securely affixes objects to sensitive walls without damaging them upon removal, ensuring no residue is left behind and allowing for easy repositioning of objects.
Implementation Method 1
a double-sided adhesive tape in which at least one adhesive comprises bead polymers. These allow for substantially residue-free and damage-free redetachability from different wall substrates

AI summary
The present invention relates to a double-face adhesive tape that can be removed by twisting, prying or peeling off from, e.g., a wall without leaving residues. The present invention also relates to a method for the concealed mounting on and residue-free and non-destructive removal of objects from a sensitive substrate, wherein the object is affixed to the sensitive substrate by means of the double-face adhesive tape and, as and when necessary, is removed by twisting or prying or peeling.
