Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication between a remote control device and a source device can be unstable or unreliable due to user movement, making data transmission of user inputs challenging.
Innovation Solution
The solution involves a display device equipped with first and second communication units using different wireless communication technologies (Wi-Fi and Bluetooth) to establish a wireless communication link with a remote control device, allowing adaptive path selection based on user position, and includes a processor to manage pairing and data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a direct wireless connection is used between the remote control device and the source device, then the communication structure is simple, but the communication reliability deteriorates due to user movement
Solution Approach 1:
The patent introduces a display device as an intermediary to establish an indirect communication path between the remote control device and the source device. When the direct connection is unavailable, the remote control device communicates through the display device, which receives control signals and forwards them to the source device, thereby maintaining communication reliability without significantly increasing system complexity
Solution Approach 2:
The patent implements dynamic path selection that adapts to user movement. The system automatically switches between direct connection mode and indirect connection mode through the display device based on the availability of the direct wireless link, making the communication structure flexible and reliable under varying conditions
2Reliability
If multiple communication paths are established, then the communication reliability is improved, but the device complexity increases
Solution Approach 1:
The display device serves multiple functions: it acts as a display device for normal operation and as a communication relay when the direct connection is unavailable. This multi-functionality allows the system to maintain multiple communication paths without adding dedicated relay devices, thus improving reliability while controlling complexity
