Solution Overview

Problem

Existing decoration parts for electronic devices lack sufficient firmness in combination with the base layer, leading to potential detachment and an unsatisfactory appearance profile, and the existing decoration lacks conspicuousness and firmness in appearance.

Innovation Solution

The implementation involves a decoration part for a housing of an electronic device, comprising a bearing layer, and at least one first structural part, and at least one second structural part, where the first structural part forms a first closed connection line, and the second structural part forms a second closed connection line that does not overlap with the first, allowing for specific patterns such as letters or numerals, with additional structural parts and adhesive connections to enhance stability and appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a decoration part is used on a housing of an electronic device, then appearance decoration and identification functions are achieved, but the firmness of combination with the base layer is insufficient leading to potential detachment

Engineering Contradiction:
Improvefirmness of combinationVSAvoidcombination strength
Core Design Contradiction:
ReliabilityVSStrength

Solution Approach 1:

The decoration part is nested within a recess of the base layer, with the bearing layer positioned inside the recess and extending beyond its boundaries. This nesting structure provides mechanical interlocking that enhances the firmness of combination and prevents detachment while maintaining appearance decoration functions

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The bearing layer extends in the thickness direction (Z-axis) beyond the boundaries of the recess, creating a three-dimensional structure that provides additional anchoring points. This dimensional extension strengthens the combination between the decoration part and base layer by distributing mechanical stresses across multiple dimensions

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Shape

If existing decoration parts are used, then appearance decoration is achieved, but the appearance profile is unsatisfactory and lacks conspicuousness

Engineering Contradiction:
Improveappearance profileVSAvoidmanufacturing complexity
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The decoration part is segmented into distinct functional regions: a bearing layer for structural support and pattern formation, and pattern-forming layers (first and second pattern layers) for visual decoration. This segmentation allows each layer to be optimized independently for its specific function while achieving an impressive appearance profile

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the decoration part have different structural characteristics - the bearing layer provides structural integrity while the pattern layers provide visual conspicuousness. The first pattern layer extends beyond the bearing layer boundaries in certain areas, creating localized visual effects that enhance the appearance profile without requiring complex overall structural changes

Inventive Principle:
Principle #3Local quality

AI summary

This application relates to the field of LOGO design technologies, and in particular, to an decoration part, a housing of an electronic device, and an electronic device, so as to improve firmness of combination between the decoration part and a base layer, to avoid falling, and improve an appearance. A decoration part includes: a bearing layer, at least one first structural part, and at least one second structural part. The bearing layer includes an upper surface and a lower surface. The at least one first structural part is disposed on the upper surface of the bearing layer. An edge of an upper surface of one first structural part forms a first closed connection line, and the upper surface of the first structural part is a surface that is of the first structural part and that is away from the bearing layer. Each second structural part is disposed on the upper surface of the first structural part and located in a region enclosed by the first closed connection line; and along a direction that is directed from the upper surface to the lower surface of the bearing layer, the second structural part includes an upper surface and a lower surface that are arranged successively, and an edge of the upper surface of the second structural part forms a second closed connection line.
