Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional engineered flooring products face issues such as moisture-related warping, thermal expansion, environmental and health hazards, and high manufacturing costs, particularly due to the use of wood and plastic components, which can lead to aesthetic and functional problems like cracking and the presence of harmful materials like heavy metals and formaldehyde.
Innovation Solution
An engineered flooring product with a core layer composed of magnesium hydroxide and magnesium chloride hydrate compounds, magnesium sulfate hydrate compounds, and fibrous stabilizing agents, which provides thermal stability, water resistance, and durability without using PVC or formaldehyde, allowing for a 'click-lock' installation system and a stable 'tongue and groove' connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If wood is used as the predominant material in flooring products, then aesthetic appeal and natural appearance are improved, but moisture resistance and dimensional stability deteriorate
Solution Approach 1:
The patent uses a composite core layer combining magnesium hydroxide, magnesium chloride, and magnesium sulfate hydrate compounds with fibrous materials. This composite structure provides both aesthetic appeal through veneer layers and dimensional stability through the hygroscopic properties of magnesium compounds that resist moisture-induced warping and swelling.
Solution Approach 2:
The patent changes the chemical composition parameters of the core layer by using specific hydrate compounds of magnesium that can absorb and release moisture without significant dimensional change. This parameter change from traditional wood or plastic cores to magnesium-based hydrate compounds resolves the contradiction between aesthetic appeal and dimensional stability.
2Ease of manufacture
If plastic components are used in engineered flooring products, then ease of manufacture and cost-effectiveness are improved, but thermal expansion resistance deteriorates
Solution Approach 1:
The patent replaces plastic components with a composite material system consisting of magnesium hydroxide, magnesium chloride, and magnesium sulfate hydrate compounds combined with fibrous materials. This composite provides thermal stability while maintaining ease of manufacture through standardized production processes for magnesium-based flooring products.
Solution Approach 2:
The patent changes the thermal properties of the core layer by using magnesium hydrate compounds that exhibit minimal thermal expansion compared to plastic materials. This parameter change in thermal behavior resolves the contradiction between ease of manufacture and thermal expansion resistance.
3Ease of manufacture
If conventional materials are used in flooring products, then cost-effectiveness is improved, but environmental safety and health hazards deteriorate
Solution Approach 1:
The patent extracts and eliminates harmful materials such as formaldehyde, heavy metals, and volatile organic compounds from the flooring product composition. By using magnesium-based hydrate compounds as the core material, the patent removes these harmful substances while maintaining cost-effectiveness through the use of abundant, naturally occurring materials.
Solution Approach 2:
The patent converts potentially harmful materials into beneficial ones by replacing formaldehyde-based adhesives and PVC plastics with magnesium-based hydrate compounds. These magnesium compounds provide the necessary structural properties without the harmful emissions and environmental issues associated with conventional materials.
4Strength
If stone veneer is used on flooring products, then aesthetic appeal and durability are improved, but compatibility with moisture-prone materials deteriorates
Solution Approach 1:
The patent uses a composite core layer of magnesium hydrate compounds that serves as a stable substrate for stone veneer applications. The magnesium-based core provides dimensional stability and moisture resistance that is compatible with stone materials, preventing the cracking and delamination that occurs when stone is applied to moisture-prone materials like wood or plastic.
Solution Approach 2:
The patent changes the moisture absorption parameters of the core layer by using magnesium hydrate compounds that maintain stable dimensions in the presence of moisture. This parameter change creates a compatible substrate for stone veneer, allowing the combination of high durability from stone with moisture resistance from the magnesium-based core.
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
The solution offers a cost-effective, easy-to-install flooring product with high durability, water resistance, and reduced thermal expansion, eliminating the need for PVC and formaldehyde, thus enhancing aesthetic appeal and environmental safety while minimizing manufacturing costs and health risks.
Implementation Method 1
the plastic components within both the LVT and WPC products are generally susceptible to thermal expansion and contraction. Such thermal expansion and contraction may eventually lead to, or may make plastic-based products prone to, gapping between floor planks
Implementation Method 2
flooring products comprising wood as the predominant material are susceptible to moisture-related issues. For example, an accumulation of moisture may cause wood flooring products (e.g. hardwood) to warp or twist
Implementation Method 3
one or more stabilizing agents, namely one or more fibrous materials that provide stability to the core layer
