Variable-Torque Friction Hinge for Multi-Orientation Kickstands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile computing devices lack effective solutions for transitioning from handheld use to other orientations without compromising their mobile aesthetic, as traditional adaptation methods are awkward and do not support varied usage scenarios.
Innovation Solution
A friction hinge mechanism that provides a variable torque profile, allowing a support component, such as a kickstand, to be adjustably attached to a computing device, enabling it to be rotated to different positions for various orientations while maintaining a consistent alignment and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional adaptation methods are used to support varied usage scenarios, then the device can be used in multiple orientations, but the mobile aesthetic is compromised and the device appears awkward
Solution Approach 1:
The kickstand is nested within the device housing, allowing it to be stored inside the device body when not in use. This nesting approach maintains the sleek mobile aesthetic while enabling multiple usage orientations when the kickstand is deployed.
Solution Approach 2:
The kickstand employs a friction hinge mechanism that allows dynamic adjustment to various angles and positions. This dynamic capability enables the device to adapt to different usage scenarios while maintaining a clean appearance when the kickstand is retracted.
2Adaptability or versatility
If a support component is added to enable multiple orientations, then usage versatility is improved, but the device complexity increases
Solution Approach 1:
The friction hinge mechanism is designed to be self-regulating, using friction between mating surfaces to maintain position without requiring additional motors, sensors, or control systems. This self-service approach enables multiple orientations while minimizing the increase in device complexity.
3Adaptability or versatility
If the kickstand is rotated to different positions, then multiple orientations are supported, but misalignment and potential damage may occur
Solution Approach 1:
The friction hinge mechanism incorporates localized friction zones at specific positions that provide natural stopping points and alignment features. This local quality approach ensures that when the kickstand is rotated to different positions, the display maintains proper alignment and prevents misalignment damage.
