Floor Panel With L-Shaped Adhesive Sheet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional resin floor panels require a separate adhesive coating process, which is labor-intensive and harmful, affecting both installation efficiency and environmental sustainability, and they are not easily recyclable or demountable.
Innovation Solution
A floor panel design featuring an adhesive sheet laminated to its rear surface with an L-shaped adhesive applied surface, covered by a protective film, utilizing eco-friendly materials like PVC or PLA with glass fiber reinforcement, eliminating the need for separate adhesive application and facilitating easy installation and demounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate adhesive coating process is used to install the floor panel, then the adhesive can be applied to the floor surface, but the installation process becomes labor-intensive and time-consuming
Solution Approach 1:
The adhesive is pre-applied to the back surface of the floor panel during manufacturing, creating a ready-to-install product. This preliminary action eliminates the need for on-site adhesive application, allowing workers to simply position and press the panel into place, thereby reducing installation time and labor requirements
Solution Approach 2:
The adhesive application process is merged with the floor panel manufacturing process. Instead of applying adhesive separately during installation, the adhesive is integrated into the production line, combining two previously separate operations into one unified process that improves both manufacturing efficiency and installation convenience
2Reliability
If oil-based adhesive is used for installation, then the adhesive provides strong bonding, but harmful volatile materials affect operators and users
Solution Approach 1:
The adhesive type is changed from oil-based to water-based formulation. This parameter change maintains the necessary bonding strength and adhesive properties while eliminating the harmful volatile organic compounds (VOCs) associated with oil-based adhesives, making the installation process safer for operators and users
Solution Approach 2:
The patent converts the potential harm of using adhesive into a benefit by selecting water-based adhesive that eliminates harmful emissions. The adhesive still provides reliable bonding but transforms the harmful oil-based volatile materials into water-based formulations that are environmentally friendly and safe for indoor air quality
3Adaptability or versatility
If conventional resin floor panel is used, then the panel can be installed on various surfaces, but the material exerts bad influence on environment and human beings
Solution Approach 1:
The floor panel is constructed as a composite structure with multiple layers including wear layer, design layer, core layer, and balancing layer. This composite construction allows the panel to maintain versatility for various installation surfaces while using environmentally friendly materials throughout, eliminating the harmful effects of conventional resin materials
