Front Cover Tone Variation via Double Injection Molding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display front covers struggle to achieve a refined and aesthetically pleasing appearance, as conventional methods like polishing or adding ornaments are insufficient in providing a sophisticated look.
Innovation Solution
A front cover design incorporating a translucent layer and a transparent layer, integrally formed through double injection molding, with a thickness variation portion to achieve tone variation, and optionally including additional materials or patterns to enhance aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If polishing or coloring methods are used to improve front cover appearance, then exterior appearance is enhanced, but manufacturing complexity and process difficulty increase
Solution Approach 1:
The patent changes the physical parameter of the molded material by using translucent and transparent materials with different optical properties. The translucent layer contains colorants while the transparent layer remains clear, creating tone variations directly in the molded product without requiring post-manufacturing polishing or coloring processes.
Solution Approach 2:
The front cover is constructed as a composite structure with multiple layers: a translucent layer containing colorants and a transparent layer without colorants. This composite material approach allows different portions of the front cover to exhibit different transparency and color characteristics, achieving refined exterior appearance while simplifying the manufacturing process by integrating multiple functions into a single molded component.
2Shape
If multiple separate components are used to achieve tone variation, then aesthetic appearance is improved, but manufacturing process becomes more complex
Solution Approach 1:
The patent merges the translucent colored layer and the transparent layer into a single integrated front cover component manufactured through one injection molding process. The molded material itself contains spatially distributed colorants that create tone variations, eliminating the need for separate components or post-assembly operations while maintaining aesthetic appearance.
Solution Approach 2:
The invention changes the distribution parameter of colorants within the molded material to create tone variations. By controlling where colorants are present or absent in the translucent portions of the front cover, the patent achieves different transparency and color effects in different regions, all within a single molded component.
3Shape
If conventional polishing methods are used, then surface appearance is improved, but time consumption and process difficulty increase
Solution Approach 1:
The patent performs the appearance enhancement action during the injection molding process itself by incorporating colorants into the translucent portions of the molded material. The tone variation and surface appearance are established in advance during manufacturing, eliminating the need for time-consuming post-manufacturing polishing or treatment operations.
