Dry Adhesive Backed Flooring for Bubble-Free Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wet adhesive installation methods for vinyl and sheet flooring are time-consuming, messy, and prone to adhesive failure, especially in high moisture environments like hospitals, where they can creep, buckle, and deform, and are costly to mitigate.
Innovation Solution
The use of dry adhesive backed flooring with a double-sided sheet adhesive, where the adhesive is pre-applied to the flooring material in a roll form, ensuring a bubble- and wrinkle-free installation and permanent adhesion to the subfloor, even under normal use conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wet adhesive is applied to subfloor for sheet flooring installation, then adhesive bonds flooring to subfloor, but installation is time-consuming, messy, and prone to adhesive failure in high moisture environments
Solution Approach 1:
The adhesive is pre-applied to the flooring material in a controlled manufacturing environment, allowing the adhesive to be positioned precisely before installation. This eliminates the time-consuming step of applying adhesive on-site and ensures proper adhesive distribution without mess or waste.
Solution Approach 2:
A double-sided adhesive sheet with release liner acts as an intermediary between the flooring material and subfloor. The release liner protects one side of the adhesive during handling and installation, while the other side bonds to the subfloor, providing reliable adhesion without direct application of wet adhesive.
2Reliability
If wet adhesive is used for sheet flooring installation, then flooring is adhered to subfloor, but flooring creeps, buckles, and deforms in high moisture areas like hospitals
Solution Approach 1:
The release liner is a disposable protective layer that is removed during installation. It protects the adhesive from moisture and contamination during storage and handling, then is discarded after serving its protective function, leaving a clean bonding interface.
Solution Approach 2:
The adhesive system comprises multiple layers including adhesive material and release liner, creating a composite structure that combines the bonding properties of the adhesive with the protective properties of the release liner, providing both adhesion and moisture resistance.
3Reliability
If wet adhesive with volatile organic compounds is applied, then flooring is bonded to subfloor, but adjacent areas must be evacuated for several days to avoid exposure
Solution Approach 1:
The harmful volatile organic compounds are extracted from the adhesive application process by using pre-applied adhesive that requires no on-site application. The adhesive is applied in a controlled manufacturing environment where emissions can be managed, eliminating the need to evacuate occupied spaces during installation.
Solution Approach 2:
The bonding function is achieved through a pre-applied adhesive system that replicates the bonding capability of wet adhesive without requiring the same application process. The double-sided adhesive sheet provides the same bonding function while eliminating the harmful emissions associated with on-site adhesive application.
4Ease of manufacture
If conventional wet adhesive installation method is used, then flooring can be installed on subfloor, but installation process is messy and requires cleanup
Solution Approach 1:
The adhesive is pre-applied and positioned on the flooring material during manufacturing, eliminating the messy on-site application process. This preliminary action ensures proper adhesive placement without spillage, waste, or contamination of the installation area.
Solution Approach 2:
The release liner serves as a clean intermediary that protects the adhesive during handling and installation. It prevents the adhesive from contacting surfaces it shouldn't, eliminating mess and reducing cleanup requirements while maintaining adhesive effectiveness.

AI summary
A dry adhesive backed flooring for being installed in a flat orientation on a subfloor, the flooring including a sheet flooring material and a double-sided sheet adhesive married to the flooring material. The installed flooring is substantially free of bubbles and wrinkles and the flooring remains substantially flat as initially applied and does not significantly rise from the subfloor, bubble or otherwise detach from the subfloor under normal use conditions for the flooring.
