Solution Overview

Problem

Conventional pigment flakes in paint systems face compatibility issues due to mis-orientation, requiring separate chemical coating steps and limiting material selection, especially when vacuum deposition is involved.

Innovation Solution

The integration of functional molecules into reflector and selective light modulator layers allows for controlled flake orientation and compatibility with paint systems without vacuum deposition or chemical baths, enhancing properties like static control and flame retardancy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional pigment flakes are used in paint systems, then random flake orientation is achieved, but compatibility with paint chemistry is poor leading to mis-orientation

Engineering Contradiction:

Improvecompatibility with paint systemVSAvoidflake orientation control

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent combines the pigment flake material with functional molecules (such as silane functionalities) directly during the vacuum deposition process, merging the optical function with the chemical compatibility function into a single integrated layer, eliminating the need for separate coating steps and ensuring proper orientation through inherent chemical compatibility

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention creates composite material structures where pigment flakes are combined with functional molecules or coatings during deposition, forming a composite that simultaneously provides optical effects and chemical compatibility with paint systems, thereby controlling flake orientation without requiring post-deposition treatment

Inventive Principle:

Principle #40Composite materials

2Adaptability or versatility

If vacuum deposition is used to prepare pigment flakes, then material selection is expanded, but functionality integration is lost requiring separate chemical coating steps

Engineering Contradiction:

Improvematerial selection optionsVSAvoidnumber of processing steps

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the vacuum deposition process with functional molecule incorporation, allowing materials to be deposited with inherent functionality rather than requiring separate chemical coating steps, thus reducing process complexity while maintaining material versatility

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention makes the vacuum deposition process universal by enabling it to produce pigment flakes with multiple functions (optical properties and chemical compatibility) simultaneously, eliminating the need for specialized separate processing steps for different material requirements

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Manufacturing precision

If separate chemical coating steps are added for compatibilization, then flake orientation control is improved, but manufacturing complexity and time increase

Engineering Contradiction:

Improveflake orientation controlVSAvoidmanufacturing efficiency

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The patent applies preliminary action by incorporating functional molecules into the pigment flake structure during the initial vacuum deposition process, so that chemical compatibility and proper orientation control are built-in from the start, eliminating the need for subsequent chemical coating steps and improving manufacturing efficiency

Inventive Principle:

Principle #10Preliminary action
