Solution Overview

Problem

Existing 3D edge strips for material panels lack variety in design and structure, and are not easily cleanable or durable.

Innovation Solution

A thermoplastic edge strip design featuring a structured base layer covered by a transparent or translucent top layer, allowing the base layer's structure to be visible while maintaining a flat surface for easy cleaning, with options for different materials and decorations to enhance optical properties.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If a structured surface is directly introduced into the edge strip surface, then surface structuring and design variety are improved, but cleaning difficulty and durability deteriorate

Engineering Contradiction:
Improvesurface structuringVSAvoidcleaning ease
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The edge strip is segmented into two functional layers: a base layer containing the structured surface design and a separate cover layer providing a smooth cleaning surface. This segmentation allows the structured base layer to be visible through the transparent cover layer while maintaining ease of cleaning on the outer smooth surface.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The structured design is copied or transferred to the base layer instead of being formed on the outer surface. The cover layer acts as a transparent copy that preserves the visual appearance of the structure while providing a smooth, cleanable outer surface.

Inventive Principle:
Principle #26Copying

2Shape

If a structured surface is directly introduced into the edge strip surface, then surface structuring and design variety are improved, but durability deteriorates

Engineering Contradiction:
Improvesurface structuringVSAvoiddurability
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The edge strip is segmented into a base layer containing the structured surface and a separate cover layer providing structural protection. This segmentation allows the structured base layer to be visible through the transparent cover layer while the cover layer protects against damage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cover layer serves as a protective cushion that is applied beforehand to protect the structured base layer from mechanical damage, scratches, and wear during use and processing.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Reliability

If a transparent top layer is added to cover the base layer, then durability and cleanability are improved, but device complexity increases

Engineering Contradiction:
ImprovedurabilityVSAvoidlayer structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The base layer and cover layer are merged into a single integrated component through coextrusion or post-coextrusion processes. This combining approach creates a multi-layer structure that functions as one piece, simplifying installation and reducing the number of separate components needed.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cover layer serves multiple functions simultaneously: it provides structural protection (durability), maintains a smooth outer surface (cleanability), and allows visual transmission of the structured base layer (aesthetic function). This multi-functionality reduces the need for additional separate components.

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

4Adaptability or versatility

If design variety is enhanced through different materials and decorations, then adaptability is improved, but manufacturing complexity increases

Engineering Contradiction:
Improvedesign varietyVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Different materials, colors, and decorative properties are applied locally to specific layers. The base layer can have various structures and decorations visible through the cover layer, while the cover layer itself can have different material properties. This local differentiation allows design variety without requiring complex multi-component assemblies.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The edge strip uses composite material structures where the base layer and cover layer can be made from different thermoplastic materials with different properties. This composite approach enables design variety in terms of optical properties, durability, and aesthetics while maintaining a relatively simple two-layer manufacturing process through coextrusion or post-coextrusion.

Inventive Principle:
Principle #40Composite materials
