Multi-Protocol Remote Control Pairing for Multiple Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The need for separate remote controllers for different display devices in a household leads to inconvenience and inefficiency.
Innovation Solution
A remote controller system utilizing UWB, Bluetooth, and IR modules to pair with multiple display devices, enabling network connection confirmation and control through UWB and Bluetooth, with IR as a fallback for unconnected devices, and NFC for additional pairing options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate remote controllers are provided for each display device, then each display device can be controlled independently, but the number of remote controllers increases and user convenience deteriorates
Solution Approach 1:
The remote controller is designed to control multiple display devices through multiple communication protocols (IR, Bluetooth, UWB). A single remote controller can pair with and control different display devices in different locations, eliminating the need for separate remote controllers for each device while maintaining reliable control functionality.
2Ease of operation
If a single remote controller controls multiple display devices, then user convenience improves, but device complexity increases due to multiple communication protocols
Solution Approach 1:
The remote controller incorporates multiple independent communication modules (IR module, Bluetooth module, UWB module) that can operate independently. Each module handles specific communication protocols, allowing the system to manage complexity through functional segmentation while providing universal control capability.
Solution Approach 2:
The remote controller acts as an intermediary device that bridges different display devices using different communication protocols. It translates and transmits control signals through appropriate protocols to reach the target device, simplifying the user interface while managing backend complexity.
3Measurement precision
If UWB and Bluetooth modules are used for network connection, then control precision improves, but energy consumption increases
Solution Approach 1:
The remote controller uses UWB and Bluetooth modules for initial device detection and pairing, then transitions to more energy-efficient communication methods for ongoing control. The system periodically activates high-precision modules only when needed for device discovery or protocol negotiation, reducing overall energy consumption while maintaining detection precision.

AI summary
A display device control system includes a first display device configured to include a first ultra-wideband (UWB) module and a first Bluetooth module, a second display device, and a remote controller configured to include an infrared (IR) module, a second UWB module, and a second Bluetooth module. The first display device and the remote controller are paired with each other. When the second display device includes a third UWB module and a third Bluetooth module, the third UWB module of the second display device senses the remote controller, the first display device and the remote controller are unpaired with each other, and the second display device and the remote controller are paired with each other.
