Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in automatically selecting the closest set top box when multiple devices with Wi-Fi and Bluetooth connections are present, leading to inefficient remote control pairing and potential connectivity issues.
Innovation Solution
Implementing a radio communication device with a receiver to determine Received Signal Strength Indication (RSSI) from multiple devices and a selection circuit to pair with the device having the strongest signal, using Bluetooth Low Energy (BLE) for proximity detection and Wi-Fi for network communication, allowing automatic selection and pairing with the closest set top box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual selection of set top box is implemented, then user can choose specific device, but user experience deteriorates due to manual intervention requirement and potential connectivity issues
Solution Approach 1:
The system automatically performs device selection and pairing without requiring user intervention. The radio communication device autonomously determines RSSI values from multiple set top boxes, selects the optimal device based on signal strength, and initiates pairing automatically, allowing the system to serve itself rather than requiring manual user operation
Solution Approach 2:
The system performs preliminary RSSI measurements and device evaluations before the actual pairing operation. By pre-determining which set top box has the strongest signal and preparing the pairing information in advance, the system eliminates the need for manual selection during the pairing moment, thereby reducing overall pairing time
2Productivity
If automatic selection based on RSSI is implemented, then pairing speed improves, but device complexity increases due to additional determination circuits and signal analysis requirements
Solution Approach 1:
The patent replaces manual mechanical selection operations with automated electronic RSSI-based determination. Instead of requiring users to manually select devices through interface interactions, the system uses electronic signal strength measurement and automatic comparison circuits to determine the optimal set top box, thereby increasing pairing speed while the added electronic complexity is justified by the elimination of manual operations
3Adaptability or versatility
If multiple set top boxes are supported, then system versatility improves, but connection reliability deteriorates due to competition and selection difficulties
Solution Approach 1:
The system implements feedback by continuously monitoring RSSI values from multiple set top boxes and using this information to make intelligent connection decisions. The radio communication device receives signal strength information from competing devices, processes this feedback data through determination circuits, and selects the set top box with the strongest signal, thereby ensuring connection reliability while supporting multiple devices
Solution Approach 2:
The system changes the selection parameter from arbitrary or manual choice to objective RSSI-based measurement. By using received signal strength as the decisive parameter for device selection, the system objectively determines which set top box provides the most reliable connection, eliminating selection difficulties and ensuring stable connections even when multiple devices are present
