Electronic Device Housing Multi-Color Deposition and Delamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for electronic device housings that offer improved aesthetic appeal and design, as users prefer devices with unique and appealing external appearances, particularly in terms of color and texture, to differentiate them from similar function devices.
Innovation Solution
A method of manufacturing a housing involving lamination of deposition layers, application of color paint, and delamination to create multiple color areas, with the first deposition layer visible through the printing layer, allowing for a metallic color effect and enhanced visual appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If multiple deposition layers are laminated to create multiple color areas, then aesthetic appeal is improved, but manufacturing complexity increases
Solution Approach 1:
The housing surface is segmented into multiple color areas by dividing the deposition process into separate layers (first deposition layer, second deposition layer, third deposition layer) that can be independently controlled and patterned, allowing complex multi-color designs to be achieved through systematic segmentation of the manufacturing process
Solution Approach 2:
The mask layers are prepared and positioned in advance before the deposition process begins, allowing the deposition layers to be patterned with precise geometric shapes and arrangements. This preliminary masking action enables complex multi-color patterns to be created systematically rather than through trial-and-error
2Shape
If delamination is used to expose underlying deposition layers, then visual appeal is improved, but manufacturing precision requirements increase
Solution Approach 1:
The mask layers are designed with specific local properties - they are positioned only in areas where delamination is desired, and their geometry is precisely controlled to define the boundaries of each color area. This local quality control ensures that delamination occurs only where intended, exposing the underlying deposition layers with high precision
Solution Approach 2:
The mask layers serve as intermediary elements that facilitate controlled delamination. These mask layers are temporarily attached to the housing surface, protect certain areas during deposition, and are subsequently removed to reveal the underlying deposition layers in precise patterns, acting as a mediator between the deposition process and the final multi-color appearance
