Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Decking materials made from manufactured composite materials often weigh more than their wood counterparts and lack the aesthetic appeal of wood, necessitating additional fascia panels and trim pieces for appearance, which can complicate installation and increase material costs.

Innovation Solution

Manufactured deck boards and fascia panels are designed with cores comprising honeycomb, folded, or dimpled structures, combined with polymeric layers to reduce weight and enhance structural integrity, while thermoforming processes create these cores and layers for improved manufacturing efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If decking is made from manufactured composite materials, then durability and low maintenance are improved, but weight increases significantly

Engineering Contradiction:

ImprovedurabilityVSAvoidweight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The deck board is divided into multiple functional layers: a core layer providing structural support, and outer layers providing aesthetic appearance. This segmentation allows each layer to be optimized independently - the core can use lightweight materials while outer layers provide durability and wood-like appearance, resolving the contradiction between weight and reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention uses composite construction with a core layer made of one material and outer layers made of different materials. This composite approach enables the board to achieve the durability of composite materials while reducing overall weight through strategic material selection and layering, directly addressing the weight-durability contradiction.

Inventive Principle:

Principle #40Composite materials

2Shape

If manufactured composite decking is used, then structural characteristics can mimic wood, but additional fascia panels and trim pieces are needed for appearance

Engineering Contradiction:

Improveaesthetic appearanceVSAvoidinstallation complexity

Core Design Contradiction:

ShapeVSDevice complexity

Solution Approach 1:

The invention merges multiple functions into a single integrated deck board component. The board itself provides both structural support and aesthetic appearance through its multi-layer construction with wood-imitating outer layers, eliminating the need for separate fascia panels and trim pieces. This integration reduces installation complexity while maintaining aesthetic appeal.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The deck board is designed as a universal component that performs multiple functions: structural support, aesthetic appearance, and edge finishing. The multi-layer construction with different material properties allows the single board to replace what would traditionally require multiple separate components, simplifying the overall deck system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If manufactured composite decking is used, then durability is improved, but material costs and installation labor costs increase

Engineering Contradiction:

ImprovedurabilityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

By segmenting the deck board into layers with different functions, the invention allows for cost-effective manufacturing. The core layer can use economical materials while outer layers provide aesthetic value, enabling competitive pricing. This segmentation also simplifies the manufacturing process through specialized equipment for each layer, reducing overall production costs.
