Waterproof Composite Flooring Planks with Click-Lock Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current waterproof flooring options, such as laminate and natural wood, are prone to moisture-related issues like swelling, warping, and damage, limiting their use in wet areas, while alternative materials like ceramic tile and rubber/vinyl flooring are costly, aesthetically limited, and uncomfortable underfoot.
Innovation Solution
A waterproof engineered flooring plank with a composite core made from bamboo, wood, or cork dust combined with high-density polyethylene or PVC, providing a rigid, moisture-resistant, and dimensionally stable surface that can be installed as a floating floor without adhesives, using a click-lock system and featuring a durable, visually appealing wear layer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If laminate or natural wood flooring is used, then the flooring provides a wooden appearance and reasonable cost, but the flooring is prone to swelling, warping, and damage when exposed to moisture
Solution Approach 1:
The patent applies composite materials by combining bamboo dust, wood dust, or cork dust with high-density polyethylene or PVC to create a composite core layer. This composite structure integrates the dimensional stability of plastics with the aesthetic qualities of natural materials, achieving moisture resistance while maintaining a wooden appearance and preventing swelling and warping.
2Reliability
If ceramic tile or stone is used, then the flooring provides moisture resistance, but the flooring is costly and cold underfoot
Solution Approach 1:
The patent uses composite materials made from recycled bamboo, wood, or cork dust combined with plastics to create a cost-effective alternative to ceramic tile and stone. This composite core provides moisture resistance while being more economical and comfortable underfoot due to the insulating properties of the natural fiber content.
3Ease of operation
If rubber or vinyl flooring is used, then the flooring is inexpensive and comfortable, but imperfections from the subfloor transfer through and adhesives are compromised by moisture
Solution Approach 1:
The patent employs composite materials with a rigid plastic-bamboo/wood/cork core that provides structural stability, preventing subfloor imperfections from transferring through. The composite structure maintains adhesive strength in moist environments while preserving comfort underfoot, overcoming the limitations of pure rubber or vinyl flooring.
4Ease of manufacture
If laminate flooring is used, then the flooring provides reasonable cost and ease of installation, but the flooring lacks rigidity and allows subfloor imperfections to show
Solution Approach 1:
The patent utilizes composite materials combining high-density polyethylene or PVC with bamboo, wood, or cork dust to create a core that maintains the ease of installation of laminate flooring while significantly improving rigidity. The composite structure prevents subfloor imperfections from showing through while retaining click-lock installation systems.
