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 patent implements a universal remote controller that can control multiple display devices through network connectivity. The remote controller is designed to communicate with both the first display device (directly paired) and the second display device (via network relay), allowing a single device to perform the functions previously requiring multiple separate remote controllers. This multi-functionality resolves the contradiction by maintaining independent control capability while eliminating the need for multiple remotes.
Solution Approach 2:
The first display device acts as an intermediary or mediator between the remote controller and the second display device. When the remote controller targets the second display device, the first display device receives the control signal via network communication and relays it to the second display device. This intermediary mechanism enables a single remote controller to control multiple display devices independently, resolving the contradiction between independent control and user convenience.
2Ease of operation
If a single remote controller controls multiple display devices, then user convenience improves, but the system complexity increases due to multiple communication protocols
Solution Approach 1:
The first display device serves as an intermediary that simplifies the communication architecture. Instead of requiring the remote controller to directly communicate with multiple display devices using different protocols, the first display device receives control signals from the remote controller and relays appropriate signals to the second display device through network communication. This intermediary approach reduces system complexity by centralizing the communication logic.
Solution Approach 2:
The remote controller is designed with universal communication capabilities that can interface with multiple display devices through a standardized protocol. The controller can identify and communicate with different display devices (first and second) using a unified communication framework, reducing the need for multiple specialized communication modules and simplifying the overall system architecture.
3Measurement precision
If UWB and Bluetooth technologies are integrated for device detection, then detection accuracy improves, but the device complexity increases
Solution Approach 1:
The detection system is segmented into two distinct functional layers: UWB technology handles proximity detection and spatial positioning, while Bluetooth technology handles device identification and pairing information exchange. By dividing the detection functionality into these specialized segments, the system achieves high detection accuracy through complementary technologies while managing complexity through clear functional separation. Each technology performs its optimized function without requiring the full system to be overly complex.

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.
