Rotatable Contact Portion for Detachable Keyboard Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch products, such as pad computers, lack a detachable physical keyboard for efficient typing, and when included, the keyboard becomes a burden when not needed, and existing solutions for supporting the device for viewing require additional, inconvenient accessories.
Innovation Solution
An electronic device design featuring a main body with a display unit and a rotatable first contact portion that can detachably engage with an input body, allowing the device to function as both a traditional laptop and a standalone tablet, with the input body also serving as a support for the device when detached, using a wedge-shaped contact mechanism and adjustable positioning system for secure assembly and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a physical keyboard is integrated into the pad computer, then typing efficiency is improved, but portability and convenience deteriorate when the keyboard is not needed
Solution Approach 1:
The keyboard is separated from the main pad computer body into an independent detachable input body. This segmentation allows the keyboard to be attached only when needed for typing, maintaining the portability of the pad computer when the keyboard is not required, while still providing full typing functionality when assembled together.
2Ease of operation
If a separate support member is added to support the pad computer at an angle, then viewing convenience is improved, but device complexity and portability deteriorate
Solution Approach 1:
The first contact portion is designed with multi-functionality: it serves as the connection interface for the keyboard when assembled, and simultaneously functions as a support structure that can prop up the pad computer at an ergonomic viewing angle when the keyboard is detached. This eliminates the need for separate support accessories.
3Volume of moving object
If the contact portion thickness is reduced to maintain compact form factor, then portability is improved, but structural strength and reliability may deteriorate
Solution Approach 1:
The contact portions are designed with localized thickness optimization: the first contact portion has a thickness smaller than the display unit to maintain overall device thinness, while the second contact portion is designed with a wedge-shaped cross-section that provides sufficient structural strength for reliable surface-to-surface engagement. This local quality differentiation maintains both compact form factor and connection reliability.

AI summary
An electronic device includes a main body and an input body. The main body has a display unit and a first contact portion rotatably connected to the display unit. The first contact portion has a first surface and a second surface opposite to the first surface, and at least one part of the first contact portion has a thickness smaller than a thickness of the display unit. The input body includes a second contact portion with a contact surface. When the input body is detachably connected to the main body, the display unit is operable to rotate with respect to the input body, and the contact surface of the second contact portion is operable to engage with the first or second surfaces of the first contact portion by surface-to-surface contacting.
