Wireless Lighting Configuration Via One USB Dongle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wireless mouse and keyboard systems using separate USB dongles experience RF interference and require multiple USB ports, leading to performance degradation and resource inefficiency.
Innovation Solution
A system and method utilizing a single USB dongle to coordinate communication between multiple human interface devices, dividing data transmission into time slots and allocating dedicated timeslots for data and acknowledgment, enabling simultaneous operation without interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate USB dongles are used for each wireless HID device, then each device can operate independently, but RF interference and power blocking occur between devices
Solution Approach 1:
The patent combines multiple wireless HID devices (mouse, keyboard, etc.) to share a single USB dongle, eliminating RF interference between separate dongles while maintaining device independence through logical separation in the software layer
Solution Approach 2:
The single USB dongle is designed to serve multiple wireless HID devices simultaneously, providing universal connectivity and eliminating the need for dedicated dongles for each device
2Ease of operation
If separate USB dongles are used for each wireless HID device, then each device has dedicated connectivity, but multiple USB ports are occupied
Solution Approach 1:
Multiple wireless HID devices share a single USB dongle connection, reducing the number of occupied USB ports from N to 1 while maintaining dedicated logical channels for each device
Solution Approach 2:
The USB dongle is designed with multi-functional capability to handle multiple HID devices simultaneously through a single interface, reducing system complexity
3Productivity
If multiple devices transmit data simultaneously on the same channel, then resource efficiency improves, but data transmission reliability may degrade
Solution Approach 1:
The shared communication channel is segmented into dedicated time slots for different devices, allowing simultaneous operation without interference while maintaining data transmission reliability
Solution Approach 2:
Devices transmit data in periodic time slots rather than continuously, with each device having allocated transmission windows that prevent conflicts while maximizing channel utilization

AI summary
A method, a computer readable medium, and an apparatus for wireless communication are provided. The apparatus may receive, via a radio frequency channel, a first data from a first human interface device at a first time slot of a frame. The apparatus may transmit the first data to a computing device. The apparatus may receive, via the radio frequency channel, a second data from a second human interface device at a second time slot of the frame. The apparatus may transmit the second data to the computing device. The apparatus may transmit, via the radio frequency channel at a third time slot of the frame, at least one of a first acknowledgment to the first data, a first lighting effect configuration data for the first human interface device, a second acknowledgment to the second data, or a second lighting effect configuration data for the second human interface device.
