Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Bluetooth keyboards with protective cases for tablet PCs are limited in flexibility due to restricted rotational axes, leading to inflexible screen orientation adjustments and increased complexity and cost.
Innovation Solution
A Bluetooth keyboard with a protective case that allows bi-directional rotation using a swivel base with a locking member and resilient element, enabling rotation around two perpendicular axes for enhanced flexibility and simplified installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the protective case is designed to rotate only around a horizontal axis, then the structure is simpler, but the flexibility of screen orientation adjustment is limited
Solution Approach 1:
The patent introduces rotation around a second axis (vertical axis) in addition to the first horizontal axis, transforming single-axis rotation into bi-directional rotation. This dimensional expansion enables the protective case to adjust screen orientation in multiple directions, significantly improving adaptability while maintaining relatively simple structural components.
Solution Approach 2:
The rotation mechanism is divided into two independent rotational axes with separate control. The first axis handles horizontal rotation while the second axis handles vertical rotation, allowing each axis to be implemented with simpler, independent components rather than a single complex multi-axis mechanism.
2Adaptability or versatility
If bi-directional rotation is implemented to improve flexibility, then screen orientation adjustment is enhanced, but the structure becomes more complex and installation becomes more inconvenient
Solution Approach 1:
The resilient element (spring) automatically pushes the locking member toward the positioning sleeve to engage the locking mechanism. This self-actuating feature eliminates the need for manual installation of the spring and reduces assembly steps, making installation more convenient while maintaining bi-directional rotation functionality.
Solution Approach 2:
The locking member serves multiple functions: it locks the protective case at desired angles during rotation, and simultaneously acts as a positioning element for the resilient element. This merging of functions reduces the total number of components needed, simplifying both structure and installation.
3Adaptability or versatility
If improved Bluetooth keyboard with protective case is designed to have bi-directional rotation, then flexibility of use is improved, but production cost increases
Solution Approach 1:
The locking member is designed to be easily replaceable and the resilient element is a standard spring component that can be mass-produced at low cost. This design approach allows for cost-effective manufacturing while maintaining the bi-directional rotation feature, as the components can be produced through conventional manufacturing processes.
Solution Approach 2:
The locking mechanism uses simple, inexpensive components such as a basic locking member and a standard resilient element that can be mass-produced at low cost. These components are designed to be affordable and easily replaceable, keeping production costs low while providing the necessary bi-directional rotation functionality.

AI summary
A Bluetooth keyboard with a protective case for a tablet PC is disclosed, including a keyboard body, a protective case for fixed installation of the tablet PC, a swivel base, and a locking member. The keyboard body is provided with a positioning sleeve, a lower end of the swivel base is configured to be rotatably inserted in the positioning sleeve and rotatable relative to the positioning sleeve around a first axis of rotation. The locking member is removably mounted in the mounting slot and is configured to be embedded in the inset slots. The Bluetooth keyboard has a two-way rotation function, which can adjust orientations of screen of the tablet PC fixed on the protective case to improve the flexibility of use, and makes the configuration more simple, easy to install, and can reduce production costs.
