Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device pairing methods, such as IR-assisted pairing, require line-of-sight and lack flexibility in identifying the best device for pairing based on distance, and Bluetooth Low Energy (BLE) pairing processes need improvements for efficient device selection.
Innovation Solution
A device capable of using Bluetooth Low Energy (BLE) for wireless communication and incorporating a universal audio device pairing assistant that utilizes a preferred command matrix to determine the optimal communication method (IR, RF, CEC) based on device capabilities and user activities, enabling flexible and reliable device control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IR-assisted pairing is used, then device pairing can be established, but line-of-sight is required which limits flexibility
Solution Approach 1:
The patent introduces an intermediary device (such as a smartphone or tablet with a camera) that captures images of the target device's display or indicators. This intermediary transfers information between the target device and the controlling device, eliminating the need for direct line-of-sight IR communication while maintaining secure pairing through image analysis
2Adaptability or versatility
If BLE pairing process is used, then line-of-sight issues are avoided, but device selection based on distance and capabilities is insufficient
Solution Approach 1:
The patent implements feedback mechanisms where the controlling device receives information about the target device's capabilities, current state, and spatial relationship through the intermediary. This feedback loop enables the system to evaluate multiple potential target devices and select the most appropriate one based on real-time conditions such as distance, capability matching, and user context
Solution Approach 2:
The patent makes the pairing process dynamic by continuously evaluating device capabilities, distances, and user interactions. The system adapts its selection criteria based on real-time conditions, allowing the optimal target device to be identified and selected during the pairing process rather than using static pre-configured pairings
