Multilayer Adhesive Tape for Sealing Wall Panel Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gaps between interior wall panels and fixtures in buildings often result in poor aesthetics and thermal losses due to air infiltration, as existing methods for sealing these gaps are inefficient and difficult to implement effectively.
Innovation Solution
A multilayered adhesive tape and sheet with distinct materials for different sections, allowing for plastic conformation and secure adhesion to edges and bodies, effectively covering and sealing gaps between wall panels and fixtures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If loose drywall patching compound is used to fill gaps, then the gap can be filled, but the aesthetics are poor and the process is difficult
Solution Approach 1:
The sealing device is divided into multiple functional sections: a first section that conforms to the fixture, a second section that bridges the gap, and a third section that conforms to the panel edge. This segmentation allows each section to perform its specific function optimally, achieving both ease of installation and aesthetic quality.
Solution Approach 2:
The device uses composite construction with a foam core material providing structural support and a flexible coating material allowing plastic conformation to surfaces. This composite structure enables the device to maintain its shape while adapting to irregular surfaces, resolving the contradiction between ease of application and aesthetic finish.
2Ease of manufacture
If the gap is left uncovered, then the installation is simple, but thermal losses occur due to air infiltration
Solution Approach 1:
The sealing device uses a flexible foam core that can be plastic conformally adapted to the geometry of the gap between the fixture and panel. This flexible structure allows the device to be easily installed while effectively sealing the gap to prevent air infiltration and thermal losses.
Solution Approach 2:
The device acts as an intermediary sealing element between the fixture and the panel, filling the gap and preventing air flow. This intermediary structure simultaneously achieves ease of installation through its flexible nature and effective thermal sealing.
3Manufacturing precision
If fixture covers are used to hide gaps, then aesthetics are improved, but insufficient structural support is provided when gaps are too large
Solution Approach 1:
The device combines a foam core material providing structural strength and rigidity with a flexible coating material that allows plastic conformation to surfaces. This composite construction enables the device to provide sufficient structural support for large gaps while maintaining aesthetic quality through its ability to conform to irregular surfaces.
Solution Approach 2:
The device utilizes plastic conformation, a parameter change in the material state, to allow the flexible coating to adapt to the geometry of the gap and underlying surfaces. This parameter change enables the device to maintain structural integrity while achieving aesthetic alignment with irregular surfaces.

Implementation Method 1
An adhesive is located on a backside of the first section to secure the device to the edge of the surface
Implementation Method 2
The first section is formed of a first material configured to be bent and molded to plastically conform to an edge of a surface

AI summary
Devices and methods covering a gap between an edge of a surface and a body exposed through an opening in the surface defined by the edge. Such a device has at least first and second sections formed of different materials. The device is positioned so that the second section is over a portion of the surface adjacent the opening and the first section extends over the gap and the opening. After removing a release liner releasably secured to a backside of the first section to cover an adhesive, portions of the first section are bent and molded to plastically conform the portions to the edge of the surface while the second section remains over the portion of the surface adjacent the opening. The body is then contacted with the backside of the first section such that the backside of the first section is adhered to the body with the adhesive.
