Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device housings lack the ability to express diverse textures and colors beyond uniform surfaces, and etching processes are limited in creating irregularities with mirror-finishing due to reactivity with metal, making it difficult to enhance aesthetic appeal and functionality.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a uniform surface shape is used for the housing, then manufacturing is simple, but aesthetic appeal and texture diversity are limited
Solution Approach 1:
The housing surface is divided into different regions with distinct properties: irregularities provide a matte texture in certain areas while mirror surfaces provide reflective areas in other regions. This local differentiation allows diverse textures and colors on the housing surface without complicating the overall manufacturing process, as both regions can be formed through oxidation treatment of a metal housing.
Solution Approach 2:
The patent utilizes oxidation treatment to create different colored regions on the housing surface. The irregularities region and mirror surfaces region can exhibit different colors through controlled oxidation, enhancing aesthetic appeal. The color variation is achieved by controlling oxidation conditions in different areas, allowing diverse visual appearance while maintaining manufacturing simplicity.
2Shape
If etching process is used to create irregularities, then surface texture is enhanced, but mirror-finishing becomes difficult due to metal reactivity
Solution Approach 1:
The metal housing undergoes oxidation treatment first to form oxide layers on the surface, creating the irregularities region and mirror surfaces region with distinct textures. After oxidation, the housing is then subjected to mirror-finishing processing. This preliminary oxidation action protects the metal surface and enables subsequent mirror-finishing to be performed successfully, resolving the reactivity issue.
Solution Approach 2:
The patent changes the surface state of the metal housing through oxidation treatment, transforming it from a reactive metal surface to an oxidized surface that is more amenable to mirror-finishing. By controlling oxidation parameters (such as oxidation time, temperature, and atmosphere), the patent creates regions with different surface properties that can subsequently be mirror-finished effectively.
3Shape
If mirror surfaces are formed on irregularities, then aesthetic appeal is enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent combines the formation of irregularities and mirror surfaces into a single integrated manufacturing process. The metal housing is subjected to oxidation treatment to create differentiated regions, followed by mirror-finishing processing that simultaneously enhances both regions. This merging of steps reduces manufacturing complexity compared to treating irregularities and mirror surfaces as separate, sequential operations.
Solution Approach 2:
The oxidation treatment process serves multiple functions: it creates the irregularities region with matte texture, forms the mirror surfaces region with reflective properties, and prepares both regions for subsequent mirror-finishing. This multi-functionality of the oxidation step reduces the number of separate manufacturing operations needed, thereby reducing overall process complexity.
4Ease of manufacture
If smooth surface is used for housing, then manufacturing is easy, but grip feeling and impact resistance are reduced
Solution Approach 1:
The housing surface is differentiated into an irregularities region that provides enhanced grip feeling and a mirror surfaces region that maintains aesthetic appeal. The irregularities region, formed through oxidation treatment, creates a textured surface that increases friction and improves grip, while the mirror surfaces region provides a smooth, reflective area. This local differentiation allows the housing to have both easy manufacturing and improved grip characteristics.
