Magnetic Keyboard Stand with Torque Hinge for Tablet Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a keyboard and stand combination that is easily detachable and attachable, providing stability when integrated, to accommodate both video viewing and long text input requirements for thin electronic devices like tablet PCs.
Innovation Solution
A keyboard with a recessed portion and a magnet, and a stand with a torque hinge and flexible band portion, where the stand's bar is attracted by the keyboard's magnet, allowing easy attachment and detachment while maintaining stability through magnetic attraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the keyboard and stand are integrated, then text input functionality is improved, but portability and video viewing convenience deteriorate
Solution Approach 1:
The keyboard device is divided into two separable functional components: a keyboard unit and a stand unit. The stand unit includes a stand body and a support leg, while the keyboard unit contains keys and a control unit. These components can be detached from each other, allowing the device to adapt between integrated mode (for text input) and separated mode (for video viewing), thereby resolving the contradiction between text input functionality and video viewing convenience.
2Adaptability or versatility
If the keyboard and stand are detachable, then versatility is improved, but attachment stability deteriorates
Solution Approach 1:
The connection between the keyboard unit and stand unit employs a dynamic magnetic attachment mechanism. Magnets are positioned at specific locations on both units, creating a magnetic attraction force that maintains stable connection during use. This dynamic magnetic bonding allows the components to be easily attached and detached while ensuring sufficient connection stability when integrated, resolving the contradiction between detachability and attachment stability.
3Stability of the object's composition
If strong magnetic attraction is used, then attachment stability is improved, but ease of detachment deteriorates
Solution Approach 1:
The magnetic attraction force is localized to specific regions rather than distributed uniformly. Magnets are positioned at the rear end of the keyboard unit and corresponding positions on the stand unit, creating focused magnetic bonding zones. This localized magnetic attraction provides sufficient holding strength for stability during use, while allowing easy detachment when force is applied to overcome the localized magnetic force, thus resolving the contradiction between attachment stability and ease of detachment.

AI summary
A keyboard includes: a recessed portion formed along a rear edge and open from a rear surface to a bottom surface; and a magnet located at a recessed portion top surface. A stand includes: a frame body that abuts a rear surface of an electronic apparatus; a plate connected to part of the frame body via a torque hinge, and having a distal edge abutting a placement surface in a state of being open relative to a frame surface of the frame body; a band portion connected to a long-side frame of the frame body along the long-side frame, and having a width that allows side surfaces of the electronic apparatus to be supported; and a bar of an iron material located along a distal edge of the band portion.
