Multi-Segment Folio Stand for Stable Adjustable Viewing Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional accessory devices for portable electronic devices often struggle to balance and support these devices at adjustable inclination angles, limiting viewing options and sacrificing flexibility for stability due to the weight disparity between the device and the accessory.
Innovation Solution
A multi-segmented folio with a cascading rotational support system and hinge assemblies featuring asymmetrical torque frictions and hard stops, allowing for fine adjustment of viewing angles while maintaining equilibrium, includes a base segment with an input device and attachment segments for secure mounting, enabling the device to be suspended and inclined for improved viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional accessory devices are used to support portable electronic devices, then the device can be supported at fixed positions, but the viewing angle flexibility is limited and cannot be adjusted
Solution Approach 1:
The folio is divided into multiple segments (first segment, second segment, third segment) connected by hinge assemblies, allowing each segment to rotate independently and achieve multiple viewing angles while maintaining manageable structural complexity
Solution Approach 2:
The hinge assemblies incorporate asymmetrical torque frictions that allow dynamic adjustment of viewing angles by applying torque in specific directions, enabling the structure to transition between fixed positions and adjustable states
2Weight of moving object
If the accessory device is made lighter to maintain portability, then it becomes easier to carry, but it loses the ability to balance and support the heavier electronic device stably
Solution Approach 1:
The cascading rotational support system uses the weight distribution and rotational mechanics of multiple segments to create counterbalancing effects, where the rotation of one segment compensates for the weight disparity and maintains stability during viewing angle adjustments
3Adaptability or versatility
If the folio structure is made more complex to achieve adjustable viewing angles, then viewing flexibility improves, but the device becomes less stable and harder to balance
Solution Approach 1:
The hinge assemblies feature asymmetrical torque frictions with different friction values for clockwise and counter-clockwise rotations, allowing controlled movement in one direction while maintaining stability in the other, thus achieving both flexibility and reliability
Solution Approach 2:
The asymmetrical torque frictions change the friction parameter based on rotation direction, enabling the structure to be flexible when adjustment is needed and stable when positioned, resolving the contradiction between adaptability and reliability

AI summary
Accessory devices for portable electronic devices are described. An exemplary accessory device can include a first segment coupled to a second segment via a first hinge assembly. The accessory can include a third segment coupled to the second segment via a second hinge assembly such that the second segment is positioned between the first and third segments. The accessory device can be arranged between a closed configuration and a configuration of a stand that supports the portable electronic device at a viewing angle. At the support configuration, the second segment can be at an acute angle relative to the first segment to shift the center of gravity of the system towards the middle. The third segment can be suspended above the first segment and be inclined outwards. The hinge assemblies of the system can be sufficiently stiff to withstand the weight of the electronic device.
