Colored Resin Layer Layout in Light Modulating Glass for Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light modulating bodies lack designability due to the first and second resin layers having the same color under no voltage application, limiting their aesthetic versatility.
Innovation Solution
The light modulating body comprises a first resin layer and a second resin layer with different colors, achieving a color difference in the L*a*b* color system, and specific chromatic values to enhance designability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the first resin layer and the second resin layer have the same composition, then the manufacturing process is simple, but the designability is poor because the color appears the same from both sides under no voltage application
Solution Approach 1:
The patent applies local quality by assigning different colors to the first resin layer and second resin layer. Specifically, the first resin layer has a first color and the second resin layer has a second color different from the first, allowing each side to have distinct aesthetic characteristics while maintaining the same basic structural composition and manufacturing process
Solution Approach 2:
The patent implements asymmetry by making the color configuration asymmetric between the two resin layers. While the layers may have similar structural properties, their different colors create an asymmetric visual appearance from each side, enhancing designability without complicating the manufacturing process
2Reliability
If the light modulating body uses a light modulating layer that becomes transparent under voltage application, then privacy protection is achieved, but the color appearance and design flexibility are limited
Solution Approach 1:
The patent applies color changes by incorporating a light modulating layer that changes its optical properties under voltage application. The layer transitions between a colored state (providing privacy) and a transparent state (providing visibility), while the different colored resin layers ensure that distinct color appearances are maintained from both sides during the privacy state
Solution Approach 2:
The patent implements dynamics by making the optical properties of the light modulating body changeable through voltage application. The light modulating layer dynamically switches between transparent and opaque states, allowing the color appearance to be adjusted between visible and hidden states while maintaining design flexibility through the different colored resin layers
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 configuration allows for distinct colors on either side of the light modulating body, enhancing designability and enabling achromatic or near-achromatic appearance under voltage application, improving visibility and privacy protection when used as automotive window glass.
Implementation Method 1
Since the light modulating layer in the light modulating body comes into a transparent state under application of voltage, and comes into an opaque state under no application of voltage
