Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decking materials, whether wooden or composite, face issues with maintenance, durability, and structural integrity due to environmental factors, leading to frequent and costly upkeep, and interlocking systems suffer from thermal expansion and water drainage problems.
Innovation Solution
A composite cover system with grooved surfaces and fasteners designed for easy installation, featuring grooves for liquid and vapor management, and a durable, lightweight design that minimizes maintenance, incorporates texturing for enhanced durability and aesthetic appeal, and uses self-tapping fasteners for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is used to attach deck covering, then initial attachment is achieved, but adhesive degrades over time under weather conditions leading to covering failure
Solution Approach 1:
The patent removes the adhesive layer from the attachment system entirely, replacing it with a mechanical interlocking mechanism where the deck covering is inserted through slots in the deck board and secured with fasteners. This extraction of the adhesive component eliminates its degradation issue while maintaining attachment functionality.
Solution Approach 2:
The patent introduces a intermediary fastening mechanism consisting of slots in the deck board and corresponding fasteners that mechanically secure the covering. This intermediary system replaces the direct adhesive bond, providing a more durable attachment that does not degrade under weather conditions.
2Manufacturing precision
If pressure washing and buffing are performed for optimal adhesion, then attachment quality is improved, but labor and installation cost increase
Solution Approach 1:
The patent removes the requirement for adhesive preparation steps (pressure washing and buffing) by using a mechanical fastening system. The covering is attached directly through slots and fasteners without needing to prepare the surface for adhesive bonding, significantly reducing installation time and labor requirements.
Solution Approach 2:
The patent replaces the chemical adhesion process (which requires surface preparation) with a mechanical fastening system using slots and fasteners. This substitution eliminates the need for time-consuming surface preparation while achieving reliable attachment.
3Reliability
If interlocking PVC cover system is used, then protection is provided, but differential thermal expansion causes cracking and damage
Solution Approach 1:
The patent changes the material parameter from rigid PVC to a flexible composite material that can accommodate thermal expansion and contraction. This material parameter change allows the covering to expand and contract with the deck board without causing cracks or structural damage, while maintaining the protective function.
Solution Approach 2:
The patent uses a composite material system consisting of a flexible base material with embedded reinforcing elements. This composite construction provides both the flexibility needed to accommodate thermal expansion and the strength required for protection, resolving the contradiction between rigidity for protection and flexibility for thermal movement.
4Reliability
If interlocking design is used for deck covering, then protection is achieved, but water drainage is impeded causing accumulation and mold growth
Solution Approach 1:
The patent segments the deck covering into modular sections with integrated drainage channels that run along the length of each covering piece. This segmentation allows water to flow freely through the covering system rather than accumulating, while the modular design maintains the protective function of the interlocking system.
Solution Approach 2:
The patent extracts the water drainage function from the interlocking structure by incorporating separate drainage channels and slope features. This extraction allows the interlocking mechanism to provide protection while the drainage channels independently manage water flow, preventing accumulation and mold growth.
