Solution Overview

Problem

Traditional decking systems face issues such as wood rot, maintenance requirements, noise due to direct plank placement on bearers, and invasive fixing methods that accelerate decay, especially in elevated areas like roof gardens and balconies.

Innovation Solution

A decking support system featuring connection elements with a hooked lever and engagement structures that provide a snap-fit mechanism between decking support elements and connection elements, allowing for a resilient and stable two-dimensional frame without invasive fastening, using materials like Aluminium and plastics for durability and low maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional wood or wood composite decking is used, then initial aesthetic appeal and ease of installation are improved, but durability and maintenance requirements deteriorate due to rot and decay

Engineering Contradiction:
Improveease of installationVSAvoiddurability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent employs composite materials consisting of aluminium bearers and plastic decking planks. The aluminium bearers provide structural strength and durability, while the plastic planks offer weather resistance and rot prevention. This composite approach eliminates the rot and decay issues inherent in traditional wood decking while maintaining ease of installation through the modular system.

Inventive Principle:
Principle #40Composite materials

2Stability of the object's composition

If invasive fixing means such as screws and nails are used to secure planks, then structural stability is improved, but harmful factors increase due to points of entry for water and decay

Engineering Contradiction:
Improvestructural stabilityVSAvoidwater entry and decay
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent removes invasive fixing means from the decking system. Instead of using screws or nails that create penetration points, the plastic planks are designed to rest on the aluminium bearers with overhangs that provide structural stability without requiring invasive fasteners. This extraction of harmful fixing elements eliminates points of entry for water and decay while maintaining the structural integrity of the decking.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of manufacture

If planks are laid directly on bearers, then installation simplicity is improved, but noise levels increase due to direct contact

Engineering Contradiction:
Improveinstallation simplicityVSAvoidnoise
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The patent introduces an intermediary layer between the bearers and planks in the form of a foam strip. This foam strip acts as a mediator that cushions the contact between the rigid aluminium bearers and plastic planks, thereby reducing noise transmission. The foam strip is easily integrated into the installation process, maintaining simplicity while effectively addressing the noise issue.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of manufacture

If conventional decking systems are used, then initial cost effectiveness is improved, but loss of substance increases due to rot and deterioration over time

Engineering Contradiction:
Improvecost effectivenessVSAvoidmaterial deterioration
Core Design Contradiction:
Ease of manufactureVSLoss of substance

Solution Approach 1:

The patent utilizes composite materials where aluminium bearers and plastic planks work together to prevent material deterioration. The aluminium provides corrosion resistance and structural stability, while the plastic planks resist rot and decay. This composite system eliminates the loss of substance associated with traditional wood decking that requires periodic maintenance and replacement.

Inventive Principle:
Principle #40Composite materials
