Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in achieving high design aesthetics while maintaining structural integrity, particularly in expressing patterns and colors on glass covers.
Innovation Solution
A back surface plate for electronic devices is designed with a first glass part having a pattern area and a second glass part with a complementary shape and different color, which are integrated using a high-temperature molding process to create a visually appealing and structurally robust exterior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a colored film is stacked on a glass cover to express patterns and colors, then design aesthetics are improved, but structural integrity and strength are compromised
Solution Approach 1:
The patent merges the pattern layer and the glass cover into a single integrated glass structure. The pattern is formed directly within the glass material through selective ion exchange or chemical modification, eliminating the need for separate colored films. This integration maintains structural integrity while achieving the desired aesthetic patterns and color effects.
Solution Approach 2:
The patent creates a composite glass structure with different regions having distinct optical and mechanical properties. By modifying specific areas of the glass through ion exchange or chemical treatment, the patent produces a composite material system where the patterned regions and base glass regions work together to provide both aesthetic value and structural strength.
2Shape
If multiple glass parts with different colors are integrated, then design aesthetics are enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent segments the glass manufacturing process into distinct stages: forming the base glass structure, applying mask patterns, and performing selective ion exchange or chemical modification in specific regions. This segmentation allows for precise control of color and pattern formation while maintaining a relatively simple overall manufacturing flow compared to assembling multiple separate colored glass parts.
Solution Approach 2:
The patent performs preliminary actions by pre-forming the glass structure and applying protective masks before the actual coloration process. The mask patterns are prepared in advance to define the desired pattern areas, and the ion exchange or chemical modification is then selectively applied only to the exposed regions, simplifying the overall manufacturing sequence.

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 solution allows for the expression of complex patterns and colors on the glass cover itself, enhancing the design aesthetic while ensuring the necessary strength and durability for portable electronic devices.
Implementation Method 1
a process of preheating the second glass part at a high temperature, and lowering an upper core structure of the mold structure toward the lower core structure; a process of causing the second glass part to be penetrated into the first pattern area by pressing the second glass part by the upper core structure
Implementation Method 2
causing the second glass part to be penetrated into the first pattern area by pressing the second glass part by the upper core structure
Implementation Method 3
a process of cooling the first glass part and the second glass part
