Simulated Wood Decking with Roughened PVC Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional teak wood decks on boats and yachts require high maintenance to prevent mold and mildew growth, leading to frequent cleaning and oiling, which can damage the wood and create a cycle of deterioration, and they have a limited service life due to harsh cleaning methods and physical labor requirements.
Innovation Solution
A simulated wood surface covering made of flexible polyvinyl chloride strips with a non-migrating plasticizer and coloring agent, featuring a roughened surface to mimic wood grain, and a pressure-sensitive adhesive system for easy installation on curved surfaces, reducing maintenance and labor needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If teak wood is used for deck surfaces, then it provides natural water resistance and anti-slip properties, but it requires high maintenance to prevent mold and mildew growth
Solution Approach 1:
The patent creates a simulated wood surface covering that copies the appearance and key functional properties of teak wood without using actual wood. The flexible plastic composition mimics wood grain patterns and provides similar aesthetic qualities while eliminating the biological vulnerabilities of real wood to mold and mildew.
Solution Approach 2:
The patent uses a composite material system consisting of flexible plastic composition (PVC or similar polymers), colorants to simulate wood appearance, and pressure-sensitive adhesive backing. This composite structure combines the durability and mold resistance of synthetic materials with the aesthetic qualities of natural wood.
2Ease of operation
If harsh acid cleaning is used to remove mold and mildew from teak decks, then it effectively kills spores and removes discoloration, but it damages the wood grain and reduces service life
Solution Approach 1:
The simulated wood surface acts as a disposable or long-lasting protective layer that can be easily cleaned without damage. Instead of trying to preserve the natural wood through aggressive maintenance, the patent uses a synthetic surface that tolerates thorough cleaning and can be replaced if needed, eliminating the cumulative damage problem.
Solution Approach 2:
By copying the appearance of wood grain on a synthetic surface, the patent creates a material that can withstand harsh cleaning methods without the structural damage that occurs with real wood. The simulated grain pattern remains intact even after aggressive cleaning that would raise the grain of actual wood.
3Ease of operation
If physical rubbing with steel wool or metal brush is used to clean stubborn discoloration, then it removes persistent mold and mildew, but it causes deterioration of the teak surface
Solution Approach 1:
The simulated wood surface replicates the visual texture of wood grain without the organic structure that is vulnerable to mechanical damage. The synthetic material can endure repeated physical scrubbing with steel wool or metal brushes without the surface deterioration, raised grain, or structural weakening that occurs with natural wood.
4Ease of operation
If organic oils are applied to restore teak deck finish, then it replenishes lost oil and improves appearance, but it provides more nutrients for mold and mildew growth
Solution Approach 1:
The simulated wood surface copies the satiny appearance and visual appeal of oiled teak without using organic oils. The synthetic material maintains its aesthetic qualities through its inherent properties rather than requiring organic substances that would feed mold and mildew spores.
Solution Approach 2:
The simulated wood surface is self-maintaining in that it does not require periodic application of organic oils to preserve its appearance. The synthetic material retains its visual qualities and water resistance inherently, eliminating the need for oil applications that would otherwise create nutrients for mold and mildew.

AI summary
The present invention relates to a simulated wood surface covering which is particularly useful in decking and flooring applications, said simulated wood surface covering being comprised of strips adapted to be interconnected aside of each other thereby forming an assembled simulated wood surface covering of desired dimensions to cover a substrate, wherein the strips are comprised of a simulated wood composition which is comprised of polyvinyl chloride, a non-migrating plasticizer, and a coloring agent, wherein the strips have sufficient flexibility to conform to curved surfaces and to surface irregularities, wherein the upper surface of the strips are roughened to imitate the grain structure of wooden material, wherein the strips are void of longitudinal slots wherein a pressure sensitive adhesive covers the underside of the strips, and wherein the pressure sensitive adhesive is covered by a backing so that the pressure sensitive adhesive is sandwiched between the strips and the backing.
