Tablet Case With Hinged Keyboard for Full-Size Typing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tablet computers lack effective input options for text entry and full typing capacity, as they typically do not accommodate a full-sized QWERTY keyboard and the touch-sensitive display is not responsive for normal typing, leading to limitations in text input and battery life due to their slim design.
Innovation Solution
A tablet computer case with a first panel to hold the device and a second panel featuring a keyboard, connected by a hinge, which allows the keyboard to communicate with the tablet computer, providing text input and expanding functionality, while also enabling the device to be used like a laptop.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a full-sized keyboard is integrated into the tablet device, then text input capability is improved, but device thickness and weight increase
Solution Approach 1:
The keyboard is separated from the main tablet body and placed in a detachable case, allowing the tablet to remain thin while providing keyboard functionality when needed. The case with keyboard can be attached or detached based on user needs.
Solution Approach 2:
The keyboard is nested within the protective case structure, which itself nests around the tablet device. This layered nesting allows the keyboard to be housed in a compact form that doesn't increase the tablet's core dimensions.
2Ease of operation
If a slide-out keyboard is used, then text input performance is improved, but device complexity and potential fragility increase
Solution Approach 1:
The keyboard mechanism is extracted from the main device body and placed in a separate case, simplifying the overall device structure. The keyboard case can be opened or closed independently without affecting the tablet's core functionality.
Solution Approach 2:
The keyboard case incorporates dynamic elements such as spring-loaded mechanisms or magnetic latches that allow the keyboard to slide out smoothly and return to its stored position automatically, providing ease of use without complex manual operations.
3Weight of moving object
If the device is made slim and compact, then portability is improved, but battery life and memory size are reduced
Solution Approach 1:
The case with keyboard and additional battery extends the device in the thickness dimension rather than increasing the footprint, maintaining portability while providing access to additional power capacity when the case is attached.
Solution Approach 2:
The case pre-charges an additional battery that can be quickly connected to the tablet when needed, providing extended power supply without requiring the user to carry a separate charger or wait for battery recharging.
4Reliability
If a protective case is added, then device protection is improved, but device bulk and weight increase
Solution Approach 1:
The protective case serves multiple functions simultaneously: it protects the tablet from damage, houses an extended battery for additional power, and contains a full-sized keyboard for text input. This multi-functionality reduces the need for separate accessories.
Solution Approach 2:
The protective case merges several previously separate functions (protection, power extension, and keyboard input) into a single integrated unit, reducing overall bulk compared to carrying separate protective case, battery pack, and keyboard accessory.
