Protective Cover Latch Mechanism for Tablet Keyboard Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tablet computers lack the functionality of traditional laptops, particularly in word processing and media usage, due to their portability and touch-screen interfaces, which can be cumbersome and inefficient.
Innovation Solution
A protective cover with a latch mechanism that automatically opens and secures input devices, such as keyboards, to the tablet computer using magnetic coupling, allowing for efficient conversion between clamshell and upright positions for optimal viewing and input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a physical keyboard is attached to a tablet computer to provide word processing functionality, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The patent combines the protective cover and physical keyboard into a single integrated assembly. The keyboard is built into the cover structure, eliminating the need for separate attachment mechanisms. This merging of functions reduces overall device complexity while maintaining word processing capability.
Solution Approach 2:
The protective cover serves multiple functions: it protects the tablet from physical damage, provides a physical keyboard for word processing, and includes a latch mechanism for secure attachment. This multi-functionality eliminates the need for separate accessories, reducing complexity while improving productivity.
2Reliability
If a latch mechanism is added to secure the keyboard to the tablet, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The latch mechanism is designed to automatically engage and secure the keyboard to the tablet cover without requiring manual intervention. The spring-loaded latch self-activates when the keyboard assembly is placed on the cover, providing reliable attachment while minimizing structural complexity.
Solution Approach 2:
The latch mechanism uses a spring-loaded design where the spring is compressed during attachment and then releases to secure the keyboard. The spring is recovered within the latch structure, providing reliable attachment while keeping the overall structure compact and simple.
3Ease of operation
If the latch mechanism protrudes from the housing to enable coupling, then the ease of operation is improved, but the appearance quality worsens
Solution Approach 1:
The latch mechanism transitions from a retracted state (flush with housing surface) to an extended state (protruding for coupling). This dynamic positioning allows the latch to maintain a clean appearance when not in use while providing easy access when needed. The spring-loaded mechanism enables smooth transition between states.
Solution Approach 2:
The latch mechanism is segmented into distinct functional zones: a retracted portion that maintains surface flushness for aesthetic purposes, and an extendable portion that protrudes for coupling operations. This segmentation allows the latch to satisfy both appearance and operational requirements simultaneously.

AI summary
Certain embodiments relate to a protective cover with a housing and a latch mechanism. The latch can be hingeably coupled to a back portion of the housing such that the latch is configured to rotate, via the hinge coupling, from a closed position to an open position. The latch can further be slideably coupled to the housing such that the latch is configured to laterally slide out from the back portion of the housing to an extended position, where the bottom side of the latch can be configured to couple to and secure an input device to the surface of the housing.
