Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in effectively dissipating heat while minimizing the exposure of heat dissipation structures, which compromises miniaturization and aesthetic design.
Innovation Solution
Incorporating a hinge structure with integrated vent members that guide air flow directionally through intake and exhaust portions, allowing for efficient heat dissipation without increasing device size or compromising aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a separate vent structure is added for heat dissipation, then heat dissipation function is improved, but device size and structural complexity increase
Solution Approach 1:
The patent combines the vent structure with the hinge structure by forming the vent members as integral parts of the hinge assembly. The first and second vent portions are formed on the hinge structure itself, eliminating the need for separate vent components and reducing overall structural complexity while maintaining effective heat dissipation functionality
2Shape
If vent structure exposure is minimized, then aesthetic design is improved, but heat dissipation effectiveness may be compromised
Solution Approach 1:
The vent members are designed to rotate together with the hinge structure, dynamically adjusting the vent openings based on the device's folding angle. When the device is folded, the vent members orient openings away from external surfaces to maintain aesthetics; when unfolded, they optimize airflow paths to ensure effective heat dissipation
3Volume of moving object
If space inside the device is reduced, then miniaturization is improved, but heat dissipation capacity may be reduced
Solution Approach 1:
The vent members utilize the third dimension by rotating about the rotation axis to control airflow direction. This dimensional approach allows the system to manage heat dissipation effectively without requiring additional internal space, as the rotational mechanism directs existing airflow paths rather than requiring larger vent openings or additional components

Implementation Method 1
a fan component disposed in a first space inside the first housing, and a hinge structure rotatably connecting the first housing and the second housing about a rotation axis... including an intake portion configured to suck air into the first space from the outside and an exhaust portion configured to discharge air from the first space to the outside, according to an operation of the fan component
Implementation Method 2
the hinge structure includes a vent member configured to rotate about the rotation axis, and in which a first vent portion for guiding air flow between the intake portion and the outside, and a second vent portion for guiding air flow between the exhaust portion and the outside are formed

AI summary
An electronic device includes first and second housings rotatable relative to each other, a fan inside the housing, and a hinge structure rotatably connecting the first and second housings to each other. The hinge structure includes a vent member rotating together with rotation of the first and second housings. The vent member includes first and second portions which guide first air flow between intake and exhaust openings together with operation of the fan. The first and second housings which face each other define a first angle therebetween, the first and second housings which are maximally rotated define a second angle therebetween, and the first and second housings forming a third angle between the first angle and the second angle, rotates the vent member to dispose the first and second vent portions together guiding air flow in different directions, relative to the front side of the electronic device.
