USB HID Interface Sharing Bluetooth Input Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current input methods for smartphones and tablets, such as qwerty keyboards and touch screens, are limited in user convenience and speed due to their size, and wireless smart phone keyboards using Bluetooth communication are not portable as they require carrying a separate device.
Innovation Solution
A USB apparatus that provides an input interface for external devices via Bluetooth communication without a separate input means by connecting to a terminal's USB port, sharing the terminal's input means, and complying with the USB HID standard to be recognized as a HID compliance device, allowing for Bluetooth communication and data conversion between the terminal and external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless Bluetooth keyboard is used to improve input convenience, then user convenience is improved, but portability deteriorates because users have to carry both the portable device and the wireless keyboard
Solution Approach 1:
The patent combines the Bluetooth communication unit and USB controller into a single integrated USB apparatus. This merging allows the device to function both as a Bluetooth input device and as a USB device that can share the terminal's input means, eliminating the need to carry a separate wireless keyboard while maintaining input convenience.
Solution Approach 2:
The USB apparatus is designed with multi-functionality, serving as both a Bluetooth communication device and a USB HID device. It can share the terminal's input means with external Bluetooth devices, providing universal input capability across different devices without requiring separate input means for each device.
2Productivity
If a separate wireless Bluetooth keyboard is used to improve input speed, then input speed is improved, but device complexity increases due to requiring separate input means for each device
Solution Approach 1:
The USB apparatus provides universal input capability by functioning as both a Bluetooth communication unit and a USB HID device. It can share the terminal's input means with external Bluetooth devices, allowing fast input across multiple devices without requiring separate input means for each device, thereby reducing overall system complexity.
3Adaptability or versatility
If the USB apparatus is designed to work with multiple operating systems to improve adaptability, then adaptability is improved, but device complexity increases due to requiring different drivers for different systems
Solution Approach 1:
The USB apparatus is designed with dual functionality as both a Bluetooth communication unit and a USB HID device. The USB HID interface is universally recognized by various operating systems without requiring specific drivers, while the Bluetooth unit handles device-specific communication. This universal design improves operating system compatibility without increasing driver complexity.
