Auto-connect Wireless Device Reconnection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless devices require explicit user input to reconnect to previously paired devices, which can lead to delays and inconvenience in scenarios where immediate reconnection is desired, such as when a user wants to stream data to a display or transfer files between devices.
Innovation Solution
Implementing an auto-connect feature that allows wireless devices to automatically locate and connect to designated remote devices without explicit user action, using techniques such as device type recognition, context-based triggering, and intermediary devices to manage connections, ensuring efficient reconnection in common usage scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If explicit user input is required to reconnect to previously paired devices, then connection reliability is improved, but user convenience and operational speed deteriorate
Solution Approach 1:
The system performs preliminary actions by maintaining persistent group information and device pairing data in memory during the initial connection process. When devices come back into range, the system automatically re-establishes connections using this pre-stored information without requiring user input, thus resolving the contradiction between reliable connections and user convenience.
2Reliability
If explicit user input is required to reconnect to previously paired devices, then connection security is improved, but reconnection speed and productivity deteriorate
Solution Approach 1:
Security credentials and pairing information are established during the initial connection phase and stored persistently. When reconnection is needed, the system automatically uses these pre-established security credentials to re-form connections rapidly without requiring users to re-enter security information, thus achieving both security and speed.
Solution Approach 2:
The system performs self-service by automatically managing reconnection processes using stored pairing information. The devices independently re-establish connections without user intervention, maintaining security through pre-shared credentials while achieving fast reconnection speeds.
3Ease of operation
If automatic reconnection is implemented, then user convenience and reconnection speed are improved, but device complexity and energy consumption increase
Solution Approach 1:
The system uses universal persistent data structures and memory mechanisms that serve multiple functions: storing device pairing information, maintaining group membership data, and enabling automatic reconnection. This multi-functionality reduces the need for separate complex mechanisms for each function, thereby reducing overall system complexity while enabling automatic reconnection.
4Loss of time
If automatic reconnection is implemented, then reconnection speed is improved, but energy consumption increases due to continuous scanning
Solution Approach 1:
Instead of continuous scanning, the system implements periodic scanning at intervals. Devices periodically check for previously paired devices within range and automatically reconnect when detected. This periodic approach maintains fast reconnection capability while significantly reducing energy consumption compared to continuous scanning.

AI summary
A wireless device that automatically forms a connection to a remote device in accordance with a peer-to-peer protocol. The remote device may be designated as an auto-connect device for the wireless device such that, when the wireless device determines that it is in the vicinity of the auto-connect device, it can re-form a connection to the remote device based on stored information for re-establishing connections among a persistent group of devices, but without any express user input. When a user requests that the wireless device perform a function that involves interaction with an auto-connect device, that function may be performed with the delay associated with forming a connection. Any of multiple techniques may be employed for identifying devices designated as auto-connect devices and for determining when the wireless device and a remote, auto-connect devices are in close proximity.
