Dropped Hinge Mechanism for Heat Dissipation in Foldable Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device case designs fail to effectively dissipate heat while maintaining a compact profile and smooth rotation, as cables often obstruct heat dissipation and hinder the display's ability to be positioned at various angles without limiting functionality.
Innovation Solution
A dropped hinge mechanism connects the display unit to the base unit, allowing heat to pass freely through a heat dissipating member, with a retractable cable system that moves out of the way when the display is closed, ensuring efficient heat dissipation and maintaining a slim profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a dropped hinge mechanism is used to lower display height, then the device achieves a compact profile, but heat dissipation becomes obstructed by cables and structural elements
Solution Approach 1:
The hinge mechanism is divided into multiple segments (first hinge segment, second hinge segment) that can rotate independently, allowing the display to achieve various angles while maintaining a compact profile. This segmentation enables the hinge to navigate around heat-generating components without obstructing heat dissipation paths.
Solution Approach 2:
The hinge mechanism transitions from a simple planar rotation to a multi-dimensional movement path, allowing the display to rotate in both horizontal and vertical planes. This enables the display to achieve various viewing angles while the hinge itself navigates around heat-generating components, maintaining effective heat dissipation.
2Reliability
If cables are routed through the hinge mechanism, then connectivity is maintained, but heat dissipation is obstructed and device functionality is limited
Solution Approach 1:
The cable routing is extracted from the traditional hinge path and repositioned to alternate routes that do not interfere with heat dissipation channels. This allows the hinge to maintain its rotational functionality while cables are routed through less obstructive paths, preserving both connectivity and thermal management.
Solution Approach 2:
The multi-segment hinge structure acts as an intermediary that separates cable routing from heat dissipation paths. The hinge segments can rotate independently, allowing cables to be routed through specific segments while heat dissipation occurs through other pathways, thus mediating between connectivity requirements and thermal management needs.
3Device complexity
If the display is fixed at a single angle, then structural simplicity is maintained, but adaptability and usability are reduced
Solution Approach 1:
The hinge mechanism transitions from a fixed single-angle design to a dynamic multi-position system. The multi-segment hinge allows the display to rotate to various angles and positions, providing adaptability for different viewing scenarios while maintaining a relatively simple overall structure through the use of standard hinge components.
