Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paints with bright materials face challenges in accurately controlling the position and orientation of the materials, leading to difficulties in achieving both brightness and radiotransparency, and often require costly rare metals to achieve these properties.
Innovation Solution
A paint with a sea-island structure flake, where metal island phases are linked by a resin or DLC sea phase, allowing for controlled dispersion and arrangement to achieve both brightness and radiotransparency without the need for rare metals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional bright materials are used in paint, then the coating film achieves brightness, but the position and orientation of the bright material cannot be accurately controlled, resulting in poor radiotransparency
Solution Approach 1:
The flake is segmented into multiple metal island phases distributed within a resin sea phase. This segmentation allows each island phase to function as an independent bright material unit while the overall flake structure maintains controlled geometry and orientation, resolving the contradiction between achieving brightness through material dispersion and maintaining positional control for radiotransparency.
2Reliability
If rare metals such as indium are used for coating, then both brightness and radiotransparency can be achieved, but the cost increases significantly
Solution Approach 1:
The invention uses composite flakes consisting of metal island phases embedded in a resin sea phase. This composite structure combines the optical properties of metal (brightness) with the radiotransparent properties of resin, achieving both brightness and radiotransparency using conventional materials instead of expensive rare metals like indium.
3Ease of operation
If bright material is randomly dispersed in paint, then the coating process is simple, but the positional relationship among bright materials changes constantly, making it difficult to control brightness and radiotransparency
Solution Approach 1:
The metal island phases are pre-positioned within the resin sea phase during flake formation, establishing a fixed positional relationship before the flake is applied to the substrate. This preliminary arrangement ensures that when the flake is coated, the bright material maintains stable position and orientation, enabling controlled brightness and radiotransparency while keeping the coating process simple.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The paint effectively secures a metallic luster and radio wave transmission, enabling the formation of a coating film with both desired optical and radiative properties while reducing costs.
Implementation Method 1
A plurality of island phases which are formed of metal (metallic phases) are linked by a sea phase that is formed of resin or DLC, to form a flake included in the paint of this disclosure. The positional relationship between a plurality of the island phases is in a fixed state, which makes it possible to secure a certain space between a plurality of the island phases. Including such a flake in a paint makes a plurality of island phases function as a bright material to make it possible to obtain a metallic luster
Implementation Method 2
makes it possible to transmit a radio wave via a space between a plurality of the island phases
