Hinged Keyboard Accessory for Tablet with Rotating Coupling Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auxiliary input devices for tablet computing devices are often difficult to use, undermining the advantages provided by these devices.
Innovation Solution
A hinged keyboard accessory with a coupling mechanism that allows for multiple installation modes, including a first orientation where the keyboard covers a portion of the rear exterior surface of the tablet and a second orientation where it covers a portion of the touchscreen display, along with an auxiliary display and a recess for a stylus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional auxiliary input device is used, then keyboard functionality is provided, but ease of operation deteriorates due to difficulty in use
Solution Approach 1:
The coupling mechanism is designed to be rotatable, allowing the keyboard accessory to transition between multiple installation modes (first orientation covering rear surface, second orientation covering front display). This dynamic repositioning capability enables the device to adapt to different usage scenarios, improving ease of operation by allowing users to select the most convenient configuration for their needs.
2Object-affected harmful factors
If the keyboard covers the touchscreen display, then protection is provided, but usability of the touchscreen deteriorates
Solution Approach 1:
The rotatable coupling mechanism allows the keyboard to be positioned in different orientations. Users can rotate the keyboard to cover the rear surface for protection, or rotate it to cover the front display when protection is needed. This dynamic positioning resolves the contradiction by allowing protection mode and usability mode to be selected based on current needs.
Solution Approach 2:
The keyboard accessory is designed as a separate, detachable component that can be independently positioned relative to the tablet. This segmentation allows the keyboard to be selectively placed to cover either the rear surface or the front display, enabling users to balance protection requirements with touchscreen usability based on their specific situation.
3Adaptability or versatility
If multiple installation modes are provided, then adaptability is improved, but device complexity increases
Solution Approach 1:
A single rotatable coupling mechanism enables multiple installation modes without requiring multiple separate attachment systems. The rotatability feature allows the keyboard to be positioned in different orientations (covering rear surface or front display), providing versatility while keeping the overall structure relatively simple and manageable.

AI summary
An accessory device for a tablet computing device may include a base portion having one or more input devices (e.g., keyboards, trackpads, touchscreen displays, and the like) for providing inputs to the tablet computing device. The accessory device may include a coupling mechanism for releasably coupling the base portion of the accessory device to a tablet computing device in multiple different installation modes. The coupling mechanism may include an auxiliary display for providing a graphical output along a surface of the coupling mechanism. Additionally or alternatively, the coupling mechanism may include a recess for receiving a stylus.
