Perforated Adhesive Tape for Residue-Free Surface Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stencils for decorating surfaces are multi-layered, require additional adhesion methods, and often leave residue or remove previously applied paint, failing to provide a seamless and easy-to-use solution for applying decorative designs.
Innovation Solution
A perforated tape with an adhesive coating that can be applied to surfaces, allowing for easy removal without residue and featuring design cut-outs that expose the surface for painting, eliminating the need for stencils and allowing flexible application directions and widths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multi-layered stencils are used, then the stencil can be made, but additional layers require removal before adhering to the surface
Solution Approach 1:
The stencil is divided into a base layer with adhesive and a separate design layer with cut-out patterns. This segmentation allows the design layer to be applied first to create the pattern, then the base layer is applied over it to provide adhesion and paint barrier functionality, eliminating the need to remove layers before application.
Solution Approach 2:
The patent combines multiple stencil layers into a single integrated structure where the base layer and design layer are merged. The base layer provides adhesive properties and paint blocking, while the design layer provides the decorative pattern, creating a unified stencil that requires no layer removal or additional adhesion methods.
2Ease of operation
If masking tape or hand-holding is used to secure the stencil, then the stencil can be positioned, but the process becomes more complex and time-consuming
Solution Approach 1:
The stencil base layer is equipped with adhesive properties that enable it to self-adhere to the surface upon application. This self-service capability eliminates the need for external adhesion methods like masking tape or manual holding, allowing the stencil to secure itself automatically when pressed onto the surface.
3Productivity
If conventional stencils are removed from the surface, then the painting is complete, but residue is left behind or previously applied paint is removed
Solution Approach 1:
The stencil is constructed as a thin, flexible film that can conform to the surface and be smoothly removed. This thin-film structure minimizes mechanical stress on the painted surface during removal, preventing paint damage while allowing complete stencil extraction without leaving residue.
Solution Approach 2:
The adhesive properties of the base layer are designed to change strength based on conditions - strong enough during painting to hold the stencil in place, but weakening upon removal to allow clean extraction. This parameter change in adhesion strength enables the stencil to be removed without leaving residue or damaging the painted 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
Enables an inexpensive, error-free method for applying multiple designs to various surfaces without damaging the paint or leaving residue, providing a seamless and flexible painting process.
Implementation Method 1
The bottom side has an adhesive applied to it. The bottom side adheres to a portion of the top side which is located directly underneath the bottom side when the tape is rolled on the cylinder.

AI summary
A tape includes the single sheet having a top side and a bottom side. The single sheet is rolled onto a cylinder. The cylinder is a cardboard or similar material cylinder. The sheet is comprised of a material that does not allow paint to seep through the sheet and apply to the surface. At least one cut extends through the sheet from the top side to the bottom side. The cuts form at least one opening in the sheet. The openings form decorative designs. The designs are evenly spaced longitudinally along the sheet to form a pattern. The bottom side has an adhesive applied to the bottom side. The bottom side adheres to a portion of the top side which is located directly underneath the bottom side when the tape is rolled on the cylinder. When the sheet is removed from the cylinder, the bottom side is removed from contact with the top side and is applied directly onto an application surface.
