Electronic Apparatus Grip Texture via Local Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatus grip designs that change embossing density distribution for improved grip and design aesthetics can negatively impact the overall appearance and functionality, particularly in areas that require varying textures for gripping and operation.
Innovation Solution
The use of a second exterior member with main convex portions and sub convex portions of varying shapes, created through femtosecond laser molding, allows for differentiated textures without compromising the design, enhancing gripping ease and adhesion in specific areas while maintaining a smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If embossing density distribution is changed for each area on the soft exterior member, then gripping ease and adhesion are improved, but the design of the entire grip portion is negatively affected
Solution Approach 1:
The patent applies local quality by creating different surface textures in different areas of the grip portion. Specifically, a first area has a first texture with certain embossing density, while a second area has a second texture with different embossing density. This allows each area to be optimized for its specific function (gripping vs. operation) without compromising the overall design appearance.
Solution Approach 2:
The grip portion is segmented into multiple areas with different embossing densities. The control unit divides the grip portion into a first area and a second area, applying different texture patterns to each segment. This segmentation enables independent optimization of gripping ease and operational smoothness while maintaining overall design coherence.
2Ease of operation
If embossing density is increased to improve gripping feeling, then adhesion is enhanced, but the overall design aesthetics are compromised
Solution Approach 1:
The patent implements local quality by varying the embossing density across different areas. The first area has a higher embossing density to provide enhanced adhesion and gripping feeling, while the second area has a lower embossing density to maintain smooth operation and aesthetic appearance. This localized differentiation resolves the contradiction between adhesion and design aesthetics.
3Ease of manufacture
If uniform embossing density is applied across the entire grip portion, then manufacturing is simplified, but gripping ease and adhesion are reduced in critical areas
Solution Approach 1:
The patent applies parameter changes by varying the embossing density parameter across different areas of the grip portion. The control unit adjusts the embossing density to create a first area with higher density for improved gripping and a second area with lower density for smooth operation. This parameter variation maintains manufacturing feasibility while significantly improving gripping ease and adhesion in critical areas.

AI summary
An electronic apparatus includes a first exterior member, and a second exterior member made of a material softer than that of the first exterior member and held by the first exterior member. A plurality of main convex portions are formed on a surface of the second exterior member. A plurality of sub convex portions each having a smaller shape than that of each of the main convex portions are formed on a surface of at least part of the plurality of main convex portions.
