Bluetooth Audio Device Pairing Using Preset Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Limited storage space in Bluetooth devices necessitates user-input or retrieval of connection identifiers each time a data connection is established, prolonging the connection time and decreasing efficiency.
Innovation Solution
Determine the device class of a to-be-connected Bluetooth device as audio or non-audio and use a preset pairing code for audio devices, while obtaining or retrieving a user-input or stored pairing code for non-audio devices to establish connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If connection identifiers are stored in Bluetooth device memory, then connection establishment efficiency is improved, but storage space is consumed
Solution Approach 1:
The patent changes the parameter of pairing code length from the standard 6-16 characters to a fixed 4-digit code for audio devices. This parameter change reduces the storage requirements while maintaining connection security, allowing the device to store pairing information more efficiently in limited memory space while improving connection establishment speed.
2Reliability
If user input of pairing code is required each time, then security is improved, but connection time is prolonged
Solution Approach 1:
The patent implements preliminary action by pre-configuring a default 4-digit pairing code in audio Bluetooth devices before they are put into use. This allows the pairing code to be automatically provided during connection establishment without requiring real-time user input, thus reducing connection time while maintaining security through the pre-established code.
Solution Approach 2:
The audio Bluetooth device provides its own pairing code automatically without requiring external user input or retrieval. The device serves itself by having the pairing code internally stored and automatically transmitted during the connection process, eliminating the time loss associated with manual code entry while maintaining security.
3Adaptability or versatility
If general pairing process is used for all devices, then versatility is maintained, but connection efficiency for audio devices is reduced
Solution Approach 1:
The patent applies local quality by implementing a specialized pairing mechanism specifically for audio Bluetooth devices, differentiating them from other device types. The system identifies audio devices and applies a simplified 4-digit pairing code process specifically to them, while maintaining the general pairing process for other devices. This localized optimization improves connection efficiency for audio devices without compromising the versatility of the overall system.
Solution Approach 2:
The patent segments the Bluetooth pairing process into different pathways based on device type. Audio devices receive a simplified pairing process with pre-configured 4-digit codes, while other devices continue to use the standard pairing process. This segmentation allows optimized efficiency for audio devices while maintaining versatility across all Bluetooth device types.
