Multi-Segment Folio Stand for Adjustable Tablet Balance
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 positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional accessory device is used to support portable electronic devices, then the device can be positioned at fixed angles, but the accessory cannot achieve fine adjustment of viewing angles due to weight disparity and stability requirements
Solution Approach 1:
The folio is divided into multiple segments (first segment, second segment, third segment) connected by hinge assemblies, allowing each segment to be independently positioned at different angles while maintaining overall stability through the attachment mechanism
Solution Approach 2:
The hinge assemblies incorporate asymmetrical torque frictions that allow dynamic adjustment of the folio segments to different inclination angles while maintaining stable equilibrium positions, enabling fine adjustment of viewing angles without sacrificing stability
2Weight of moving object
If the accessory device is made lighter to improve portability, then ease of carrying increases, but the ability to balance and support the electronic device at adjustable angles deteriorates
Solution Approach 1:
The attachment segment incorporates an attachment mechanism that acts as a counterweight system, using gravitational force and mechanical attachment to balance the electronic device at various inclination angles, compensating for the light weight of the folio while maintaining support capability
Solution Approach 2:
The hinge assemblies utilize asymmetrical torque frictions that change the mechanical parameters of the folio segments dynamically, allowing the light folio to achieve and maintain stable equilibrium positions at different angles by adjusting the torque characteristics rather than increasing weight
3Adaptability or versatility
If multiple rotation elements are added to enable fine adjustment of viewing angles, then adaptability improves, but device complexity increases
Solution Approach 1:
The rotational support system is segmented into multiple hinge assemblies, each with specific torque friction characteristics, allowing independent control of different folio segments to achieve fine adjustment of viewing angles while keeping each hinge assembly relatively simple in structure

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.
