Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floor, wall, and ceiling panels face issues with moisture sensitivity, dimensional instability, weight, and damage during installation due to mechanical coupling, particularly with heavy materials like fiber cement boards and PVC substrates.
Innovation Solution
Utilizing a magnesium oxide (MgO) or mineral-based board material with integrated reinforcement layers and mechanical coupling means, such as tongue and groove connections, to create panels that are dimensionally stable, lightweight, and resistant to damage during installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fiber cement boards or PVC substrates are used as panel cores, then moisture resistance and dimensional stability are improved, but weight increases leading to handling and installation problems
Solution Approach 1:
The patent uses fiber cement board as a composite material combining cement binder with reinforcing fibers (cellulose, glass, or synthetic fibers). This composite structure provides both the dimensional stability needed for moisture resistance and reduced weight compared to traditional heavy substrates, while maintaining structural integrity for mechanical coupling installation.
2Ease of manufacture
If mechanical coupling means are integrated into heavy panels, then installation connectivity is improved, but damage risk during installation increases
Solution Approach 1:
The patent applies local quality by concentrating reinforcement fibers specifically at the coupling means locations and edge regions of the panel. This localized reinforcement provides enhanced strength exactly where mechanical coupling occurs, preventing damage during installation while maintaining overall panel connectivity and ease of assembly.
3Ease of operation
If HDF substrate is used for floor panels, then ease of installation and cost are improved, but moisture sensitivity increases causing swelling and warping
Solution Approach 1:
The patent changes the fundamental material parameter of the substrate from moisture-sensitive HDF (high-density fiberboard) to moisture-resistant fiber cement board. This parameter change maintains ease of installation through similar mechanical coupling methods while eliminating the harmful moisture sensitivity that causes swelling and warping in traditional HDF panels.
