Solution Overview

Problem

Existing architectural elements used in the building trade, such as section bars for lighting or structural support, face issues with paint adhesion due to their material composition, leading to unsatisfactory finishes with color variations and discontinuities when painted.

Innovation Solution

The architectural element features a support body made of high-density material with a surface layer composed of a mixture of acrylic resin and silicon-based inert materials like quartz or marble dust, enhanced with a second layer of acrylic resin and gypsum, promoting excellent paint adhesion and preventing paint rings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If section bars are made of metal or polymer material for structural support and aesthetic purposes, then strength and structural stability are improved, but paint adhesion deteriorates causing rings and color variations

Engineering Contradiction:
Improvestructural stabilityVSAvoidpaint adhesion
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The invention applies a composite coating system consisting of a primer layer and a topcoat layer. The primer layer contains specific adhesion promoters that chemically bond to the metal or polymer substrate, while the topcoat layer provides the final aesthetic finish. This multi-layer composite structure resolves the contradiction by ensuring both structural integrity of the base material and reliable paint adhesion through specialized intermediate layers.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The invention modifies the surface properties of the section bars by applying a primer layer that changes the chemical parameters of the surface. The primer contains adhesion promoters that alter the surface energy and chemical composition, enabling subsequent paint layers to adhere properly. This parameter change transforms the incompatible surface into one that accepts paint coating reliably.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If section bars are painted to match the wall, then aesthetic continuity is improved, but painting operations become complex and time-consuming due to adhesion issues

Engineering Contradiction:
Improveaesthetic continuityVSAvoidpainting operation time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The invention applies a primer layer as a preliminary action before applying the final paint coat. This primer layer is specifically designed to adhere to the section bar substrate and create a suitable surface for the topcoat. By performing this adhesion-preparing action in advance, the painting process becomes more efficient and reliable, reducing the time and complexity associated with dealing with adhesion failures during painting operations.

Inventive Principle:
Principle #10Preliminary action

3Ease of manufacture

If section bars use standard materials for economy and simplicity, then manufacturing cost is reduced, but paint adhesion and durable finish deteriorate

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidpaint finish durability
Core Design Contradiction:
Ease of manufactureVSDuration of action of stationary object

Solution Approach 1:

The invention uses a composite coating system where the primer layer contains adhesion promoters specifically formulated to bond with standard metal or polymer section bar materials. This composite approach maintains the simplicity and economy of using standard base materials while adding a specialized coating layer that ensures durable and long-lasting paint adhesion, resolving the contradiction between manufacturing simplicity and finish durability.

Inventive Principle:
Principle #40Composite materials
