Wireless Device Pairing Information Recovery Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Paired wireless devices, such as wireless mice and dongles, often experience pairing information loss due to damage, rendering them unusable and leading to poor user experience and manufacturer reputation issues.
Innovation Solution
A system and method where each device stores identification and standard codes calculated using a calculation algorithm, allowing for automatic detection and recovery of damaged pairing information by calculating checking codes and obtaining copies of identification from the other device when mismatches are found.

Engineering Contradiction Analysis
1Reliability
If pairing information is stored in wireless devices, then wireless communication functionality is enabled, but the pairing information may be damaged leading to device unusability
Solution Approach 1:
The system performs preliminary actions by storing backup pairing information in both devices before any damage can occur. Each device maintains not only its own pairing information but also a copy of the other device's pairing information, so that if damage occurs, the backup is already in place and ready for immediate recovery without requiring external intervention.
Solution Approach 2:
The patent applies copying by creating redundant copies of pairing information. Each wireless device stores a copy of the other device's identification and standard code in addition to its own pairing information. This copying mechanism ensures that if one copy is damaged, an intact copy exists in the other device, enabling automatic recovery of the pairing relationship.
2Ease of repair
If pairing information recovery mechanism is implemented, then device functionality is restored, but additional detection and communication operations are required
Solution Approach 1:
The system implements self-service by enabling each device to autonomously detect pairing information damage and recover it using the backup copy stored in the other device. The detection mechanism compares the standard code calculated from stored identification with the stored standard code, and if they don't match, the device automatically requests and applies the backup pairing information from its paired partner, all without external intervention.
Solution Approach 2:
The patent employs feedback through a verification mechanism where each device calculates a standard code from its stored pairing identification and compares it with the stored standard code. If they match, the pairing information is intact; if they don't match, damage is detected. This feedback loop triggers the automatic recovery process, creating a closed-loop system that continuously monitors and maintains pairing information integrity.
3Ease of operation
If automatic detection and recovery is implemented, then user intervention is eliminated, but calculation and comparison operations increase processing requirements
Solution Approach 1:
The system applies partial action by performing detection and recovery operations only when necessary. Instead of continuously verifying pairing information, the mechanism triggers detection and recovery only when pairing information damage is suspected or when communication issues arise. This selective approach reduces unnecessary processing and energy consumption while still providing automatic recovery functionality when needed.

AI summary
A system for recovering pairing information of wireless devices is provided. The system may include a first device (such as a mouse) and a second device (such as a dongle) that are wirelessly paired. The system can determine a pairing information damage in one of the first device and the second device, and can automatically recover the pairing information without even noticed by the user. In this way, the system can be less affected by the pairing information damage, and can have extended product life and improved customer experience.
