3D Object Colored Layers Opaque Partition Prevent Color Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Three-dimensional objects with colored outermost surfaces can exhibit unwanted color mixing when viewed from different angles due to the short light path length at apexes, leading to uncomfortable visual experiences, as existing technologies do not adequately address this issue.
Innovation Solution
A three-dimensional object design featuring transparent colored layers on adjacent surfaces with an opaque achromatic partition layer to prevent light transmission and reflection, maintaining visual color quality by interposing the partition layer between the colored layers, which has a lower light transmittance than the colored layers and is strategically placed based on adjacent angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If transparent colored layers are formed on adjacent outer surfaces of a three-dimensional object, then the object exhibits vibrant color appearance, but color mixing occurs when viewed from different angles due to short light path length at apexes
Solution Approach 1:
An opaque or translucent partition layer is introduced as an intermediary element between adjacent colored layers on the three-dimensional object. This partition layer acts as a visual barrier that prevents light transmitted through one colored layer from mixing with adjacent colored layers, thereby eliminating color mixing artifacts while preserving the vibrant appearance of each colored surface when viewed from different angles
2Manufacturing precision
If the partition layer is made opaque to prevent color mixing, then color quality is maintained, but the partition layer becomes visible and may degrade the object's appearance
Solution Approach 1:
The partition layer's optical properties are adjusted by controlling its thickness and material composition to achieve optimal light transmittance. By fine-tuning these parameters, the partition layer provides sufficient color separation to prevent mixing while maintaining low visibility to preserve the aesthetic appearance of the three-dimensional object
Solution Approach 2:
The partition layer is strategically positioned only at critical locations where color mixing is most likely to occur, such as apex regions and edges where multiple colored surfaces converge. This localized application prevents color mixing at problem areas while leaving other regions unaffected, thereby maintaining overall aesthetic appearance

Function Achieved in This Case
The solution effectively prevents color component perception from one layer when viewing another, maintaining a satisfactory visual appearance across various angles and positions, ensuring consistent color quality without degrading the object's appearance.
Implementation Method 1
the partition layer being opaque and having one of the first color, the second color, and an achromatic color
Implementation Method 2
a first colored layer formed on the first outer surface of the shaping base, the first colored layer including a transparent material colored in a first color
