Wireless Connection Channel Switching for Local Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling electronic devices via a server incur increased communication costs and time when terminals are in close proximity, and may fail in environments without network connectivity.
Innovation Solution
The electronic device operates dual communication channels, allowing nearby terminals to control it directly through a reserved channel when connected to a peripheral device, and manages channel states based on user input and connection status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control information is transmitted through a server, then the electronic device can be controlled remotely, but communication cost and time increase
Solution Approach 1:
The patent introduces a dual-channel communication architecture where the server acts as an intermediary for remote control while a direct short-range wireless channel provides a faster alternative. The system selectively routes control commands through the server or directly through the short-range channel based on connection status, eliminating the need to always use the slower server-mediated path.
Solution Approach 2:
The patent implements dynamic channel selection where the control path changes based on real-time connection status. When a short-range wireless connection is available, the system switches to direct control; when unavailable, it falls back to server-mediated control. This dynamic adaptation optimizes response time while maintaining control capability.
2Reliability
If control information is transmitted through a server, then remote control is possible, but network connectivity is required
Solution Approach 1:
The server serves as a fallback intermediary when direct communication is not possible. The system is designed to attempt direct short-range control first, and only involves the server as an intermediary when the direct channel is unavailable, thus maintaining control capability across different environmental conditions.
Solution Approach 2:
The system changes the communication parameter (control channel) based on environmental conditions. When network connectivity is unavailable, the system switches from server-mediated communication to direct short-range wireless communication, adapting to the environmental constraints while maintaining control functionality.
3Reliability
If the electronic device maintains connection with a peripheral device, then wireless communication is established, but control by other nearby terminals is limited
Solution Approach 1:
The electronic device implements multi-functional communication capability by maintaining both a stable peripheral device connection and the ability to accept control requests from other terminals. The system can simultaneously preserve the existing connection while enabling alternative control paths through the server or direct channels, making the control system universally accessible.
Solution Approach 2:
The patent segments the control function from the connection function. The connection to the peripheral device remains stable and dedicated, while the control acceptance is separated into a distinct function that can be selectively enabled for other terminals through channel management, allowing both connection stability and control accessibility.
4Loss of time
If a reserved channel is opened for control, then direct control is enabled, but channel management complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing the reserved channel and preparing control pathways in advance. When control requests arrive, the channel is already ready, eliminating setup delays. The complexity is managed by automating the preliminary channel preparation through predefined protocols and state machine logic.
