Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing short-range wireless communication technologies face challenges in managing seamless connections between multiple devices, requiring multiple pairings and physical buttons or software controls, leading to suboptimal usability and increased device costs.
Innovation Solution
Implementing a system that allows peripheral devices to operate with a single pairing and transition between central devices using application layer software, enabling automatic discovery and pairing through collaboration between central devices, reducing the need for manual intervention and enhancing connectivity management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If peripheral devices support multiple pairings with different central devices, then connectivity versatility is improved, but device complexity and cost increase
Solution Approach 1:
The patent introduces a central device as an intermediary that performs discovery mode operations and pairing coordination on behalf of the peripheral device. The central device receives pairing information from the peripheral device and facilitates connection establishment with other central devices, thereby enabling multi-connectivity without increasing peripheral device complexity
Solution Approach 2:
The patent enables a single pairing relationship to serve multiple central devices through the discovery mode mechanism. The peripheral device maintains one pairing but can connect to multiple central devices via the coordinated discovery process, making the pairing relationship universal rather than device-specific
2Ease of operation
If physical buttons or software controls are used for connection management, then connection control precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements automatic discovery and pairing coordination where the peripheral device and central devices autonomously manage connections without user intervention. The system self-coordinates the discovery mode activation, pairing information exchange, and connection establishment, eliminating the need for physical buttons or complex software controls
3Ease of operation
If automatic discovery and pairing is implemented through central device collaboration, then ease of operation is improved, but reliability requirements increase
Solution Approach 1:
The patent incorporates feedback mechanisms where central devices exchange pairing information and connection status through the discovery mode coordination. The system uses feedback from connection establishment attempts to coordinate subsequent pairing activities, ensuring reliable operation through iterative coordination and status verification
