Solution Overview

Problem

Existing electronic devices with single-direction air outlets experience reduced heat dissipation performance when the outlet is shielded, leading to overheating.

Innovation Solution

The electronic device incorporates a concave portion with dual air outlet paths on the casing, allowing airflow to be discharged in multiple directions, and accommodates an antenna in a separate space within the casing to optimize airflow and heat dissipation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single-direction air outlet is provided at an edge of the casing, then the structure is simple, but heat dissipation performance deteriorates when the outlet is shielded

Engineering Contradiction:
Improveair outlet structureVSAvoidheat dissipation performance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The air outlet is divided into multiple independent outlet paths (first air outlet path and second air outlet path) with different discharge directions. When one path is shielded, airflow can still be discharged through other paths, ensuring heat dissipation reliability without significantly increasing structural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The air outlet transitions from a single-direction design to a multi-directional design by adding outlet paths in different spatial dimensions. The first air outlet path discharges air toward the first side surface while the second air outlet path discharges air toward the second side surface, creating redundancy in the heat dissipation system.

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

2Reliability

If a concave portion with dual air outlet paths is created, then heat dissipation reliability improves, but device complexity increases

Engineering Contradiction:
Improveheat dissipation performanceVSAvoidcasing structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The concave portion serves multiple functions: it houses the air outlet portion with multiple discharge paths, provides structural support for the antenna accommodation space, and maintains the overall casing integrity. This multi-functionality reduces the need for additional separate components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The air outlet portion is nested within the concave portion of the casing, and the antenna is accommodated in the space formed by the concave portion. This nested arrangement allows multiple functional elements to coexist within the same structural feature without proportionally increasing device complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Productivity

If the air outlet portion is arranged on the first concave surface, then airflow discharge capability improves, but available space for other components decreases

Engineering Contradiction:
Improveairflow discharge capabilityVSAvoidavailable space
Core Design Contradiction:
ProductivityVSVolume of stationary object

Solution Approach 1:

The concave portion creates additional spatial dimensions and surfaces (first concave surface and second concave surface) that can simultaneously accommodate the air outlet portion and provide space for other components like the antenna. This utilizes the third dimension to resolve space conflicts.

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

Solution Approach 2:

Different regions of the casing are assigned different functions: the first concave surface accommodates the air outlet portion for heat dissipation, while the space formed by the concave portion accommodates the antenna. This local differentiation of function optimizes both heat dissipation performance and space utilization.

Inventive Principle:
Principle #3Local quality

AI summary

An electronic device includes a casing, a concave portion, and an air outlet portion. The casing includes a first side surface, a second side surface, and a third side surface that are adjacent to each other, where two sides of the first side surface are respectively connected to the second side surface and the third side surface. The concave portion is recessed at a junction of the first side surface and the second side surface and includes a first concave surface and a second concave surface. The second side surface, the first concave surface, the second concave surface, and the first side surface are sequentially connected. The air outlet portion is arranged on the first concave surface. A length of the air outlet portion in one direction is greater than a half of a length between the second side surface and the third side surface in the direction.
