Solution Overview

Problem

Conventional ready-to-assemble structural systems, such as furniture and construction materials, lack strength, durability, and aesthetic appeal, with coatings often exhibiting poor adhesion and limited design flexibility due to their inability to be effectively applied on complex geometries.

Innovation Solution

An extrusion-coated structural system featuring a substrate with a coating material extrusion-coated to form an extruded profile member that extends outwardly, providing enhanced strength and aesthetics, and a method for assembling these systems by contacting the extruded profile member with other structural elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If conventional coating materials are applied to structural components, then aesthetic appearance is improved, but adhesion strength deteriorates

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidadhesion strength
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The patent combines the coating material application process with the extrusion process into a single integrated operation. The coating material is extruded onto the substrate in the same manufacturing step, creating a unified structure where the coating and substrate are bonded together during formation, ensuring strong adhesion while achieving desired aesthetic appearances.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The coating material is applied to the substrate during the extrusion process itself, before the substrate undergoes subsequent processing or assembly. This preliminary application ensures proper adhesion is established early in the manufacturing sequence, preventing adhesion problems that would arise from later coating attempts on complex geometries.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If coating material is applied to complex geometries with cuts, grooves, and channels, then design flexibility is improved, but coating application difficulty increases

Engineering Contradiction:
Improvedesign flexibilityVSAvoidcoating application difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The coating material is extruded onto the substrate during the initial extrusion process, before any subsequent cutting, grooving, or channel formation. This preliminary coating application ensures that complex geometries are created after the coating is already in place, eliminating the difficulty of coating intricate surfaces while maintaining design flexibility.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The manufacturing process is segmented into distinct steps: first, the substrate is extruded with the coating material already applied; then, subsequent operations like cutting and grooving are performed on the coated substrate. This segmentation allows complex geometries to be created without compromising coating application.

Inventive Principle:
Principle #1Segmentation

3Strength

If extrusion coating process is used to form profile members, then structural strength is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvestructural strengthVSAvoidmanufacturing complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent merges the coating application process with the extrusion process into a single integrated operation. The coating material is fed into the extrusion die along with the substrate material, and both are formed simultaneously in one continuous process, creating extruded profile members with integrated coating that enhances structural strength without requiring separate coating equipment or steps.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The extrusion process is made multi-functional by enabling it to both form the substrate geometry and apply the coating material in a single operation. This universal approach eliminates the need for separate coating equipment and processes, reducing manufacturing complexity while producing structurally enhanced profile members.

Inventive Principle:
Principle #6Universality (Multi-functionality)
