Smart Dongle Channel Switching for Wireless Peripheral Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic ecosystems face performance issues due to lag or failure in signal interactions between host devices and peripherals, particularly during channel switches, leading to uncomfortable user experiences and potential loss of device parameters or configurations, which are time-consuming to reset.
Innovation Solution
An electronic device with a control module and memory that generates data portions and suspends transmission if an interruption occurs, allowing for seamless channel switching without resetting by buffering and transmitting data on alternative communication channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If channel switch is performed to improve communication quality, then communication quality is improved, but lag and signal interaction failure occur
Solution Approach 1:
The patent applies preliminary action by pre-establishing multiple communication channels (first communication channel and second communication channel) before the primary channel fails. When channel switch is needed, the system already has alternative channels ready, eliminating the lag that would otherwise occur during channel switching. The control module suspends data transmission on the first channel and resumes it on the second channel without interruption, as the second channel is prepared in advance.
2Reliability
If reset operation is performed to restore device configuration, then device parameters are recovered, but time consumption increases
Solution Approach 1:
The patent implements continuity of useful action by maintaining data transmission across channel switches without interruption. The control module suspends transmission on the first channel and seamlessly resumes it on the second channel, preserving the state of data transmission and device configuration. This eliminates the need for reset operations to restore configuration, as the configuration remains intact during channel switching, thereby saving time while ensuring reliability.
3Adaptability or versatility
If data transmission is suspended during channel switch, then channel switching can be performed, but data transmission interruption occurs
Solution Approach 1:
The patent uses the control module as an intermediary that manages the transition between communication channels. The control module suspends data transmission on the first channel, prepares the second channel, and then resumes data transmission on the second channel. This intermediary management ensures that channel switching can be performed while maintaining data transmission continuity, as the control module coordinates the suspension and resumption processes to minimize interruption.
