Foldable Device Hinge Assembly with Offset Axis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computing devices with hinge assemblies often have springy keys that can interfere with user interaction, making it difficult to grasp the device properly, and lack a seamless transition between modes such as clamshell and tablet orientations, affecting user experience and device integrity.
Innovation Solution
A foldable device with a processor, memory, and a foldable frame featuring a hinge assembly with a folding axis offset from the center, allowing for a symmetrical design that enables smooth pivoting between clamshell and tablet orientations, and includes sensors to select operational modes based on user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hinge assembly with springy keys is used in conventional computing devices, then the device can achieve clamshell and tablet orientations, but the springy keys interfere with user interaction and make it difficult to grasp the device properly
Solution Approach 1:
The patent removes the problematic springy keys from the hinge assembly while retaining the core pivoting functionality. The hinge assembly is redesigned to eliminate the ejection mechanism that caused keys to spring out, allowing smooth transition between orientations without interference with user interaction or device grasping.
2Adaptability or versatility
If a conventional hinge assembly is used, then the device can pivot between modes, but seamless transition is not achieved and device integrity is compromised
Solution Approach 1:
The hinge assembly is designed with dynamic characteristics that enable smooth, continuous pivoting motion between clamshell and tablet orientations. The mechanism allows the display housing to rotate freely around the hinge axis without mechanical interference or sudden stops, ensuring seamless transition while maintaining device structural integrity throughout the motion range.
