Dual-Hinge Computing Display Support for Stable Posture Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices often face challenges in transitioning between different operating postures, such as laptop and studio modes, which can increase their footprint and hinder usability in various situations.
Innovation Solution
A computing device equipped with multiple hinges, including a base hinge and a display hinge, each with specific coefficients of friction, allows seamless transitions between configurations like laptop and studio postures, facilitated by sliding primary supports and stabilizers to maintain desired angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a computing device uses a single hinge mechanism for posture transitions, then the structure is simpler, but the device cannot maintain stable angular positions during transitions between laptop and studio modes
Solution Approach 1:
The hinge system is divided into two independent hinges: a base hinge connecting the stand to the base, and a display hinge connecting the display to the stand. Each hinge independently controls a specific angular position, allowing seamless transitions between laptop and studio postures while maintaining stability at each configuration
2Illumination intensity
If a computing device opens fully for use, then the display area is maximized, but the footprint increases and becomes inconvenient for users in confined spaces
Solution Approach 1:
The computing device employs dynamic hinge mechanisms that allow the display and stand to be positioned at multiple angular configurations. Users can transition between a fully opened laptop posture for maximum display visibility and a compact studio posture that reduces the footprint, making the device adaptable to different usage environments and space constraints
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables versatile use in multiple situations by allowing easy transitions between configurations, reducing the device's footprint when needed, and enhancing usability in confined spaces.
Implementation Method 1
The first hinge has a first coefficient of friction sufficient to maintain a first angular position between the stand and the base
Implementation Method 2
The second hinge has a second coefficient of friction sufficient to maintain a second angular position between the display and the stand
Implementation Method 3
Rotating the display into the second position includes sliding a primary support along a friction strip on the stand

AI summary
A hinge of a computing device includes a primary support connecting a display to a stand. As the display rotates about the stand, the primary support slides along a friction strip, which stabilizes the display with respect to the stand. A stabilizer may connect the stand to the base or the stand to the display.
