Detachable Keyboard Cover with Magnetic Coupler for Tablet Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tablet computers are difficult to grasp and hold during handling and transportation, leading to potential damage, and existing protective covers with integrated keyboards often limit versatility, are cumbersome to detach, and restrict typing comfort.
Innovation Solution
A protective cover for tablet computers that includes a detachable keyboard, allowing angular positioning on a support surface, with a minimal number of parts, lightweight design, and easy operation, featuring a back cover with a stand and rim for secure attachment and multiple configuration options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective cover is added to protect the tablet computer from damage during handling and transporting, then protection is improved, but the device becomes bulkier and less portable
Solution Approach 1:
The keyboard is nested within the protective cover structure, allowing the keyboard to be stored inside the cover when not in use. This eliminates the need for a separate keyboard case, reducing overall bulk while maintaining protection capabilities.
Solution Approach 2:
The protective cover and keyboard are merged into a single integrated unit. The cover serves dual purposes: protecting the tablet and housing the keyboard, thereby reducing the number of separate components and overall device volume.
2Ease of operation
If an external keyboard is added to improve typing comfort, then typing comfort is improved, but portability is reduced due to increased weight and size
Solution Approach 1:
The keyboard is integrated into the protective cover, combining two separate items (keyboard and cover) into one. This reduces the total weight compared to carrying both a standalone keyboard and a protective cover separately.
Solution Approach 2:
The keyboard is designed as a detachable component that can be separated from the cover. Users can attach the keyboard only when typing is needed, reducing the weight carried during transport while maintaining typing comfort when required.
3Adaptability or versatility
If a detachable keyboard is integrated into the protective cover to improve versatility, then versatility is improved, but the detachment and attachment process becomes cumbersome
Solution Approach 1:
The magnetic coupling mechanism replaces traditional mechanical attachment methods (screws, clips, or adhesives). The magnetic connection allows for easy one-handed attachment and detachment while ensuring secure connection during use, improving both versatility and ease of operation.
4Ease of manufacture
If the keyboard is fixed in a single flat configuration to simplify the design, then manufacturing complexity is reduced, but typing comfort is limited
Solution Approach 1:
The keyboard support structure incorporates a hinge mechanism that allows the keyboard to be adjusted between a flat configuration and an angled configuration. This dynamic adjustment capability improves typing comfort by allowing users to position the keyboard at ergonomic angles while maintaining relatively simple manufacturing through the use of a single hinge joint.

AI summary
A protective cover for a tablet computer is disclosed, which comprises a back cover and a front cover. The front cover includes an input side and a connector including a planar portion and a coupler for removably connecting the front cover to the back cover. The planar portion engages at least portion of a front surface of the tablet computer and the coupler engages an edge of the back cover.
