Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Bluetooth method is used for smart controller, then two-way communication is enabled, but the controller can only control one electronic apparatus at a time and requires re-pairing for new devices
Solution Approach 1:
The patent segments the control capability by introducing device identification mechanisms (device IDs, location information) that allow the controller to distinguish between multiple paired electronic apparatuses. The controller maintains multiple Bluetooth connections simultaneously and uses segmentation based on device identity to route control commands to the correct device, enabling control of multiple devices without requiring re-pairing.
2Device complexity
If IR remote controller is used, then one-way communication is simple, but it cannot control a specific electronic apparatus among a plurality of the same TVs
Solution Approach 1:
The patent implements feedback mechanisms where electronic apparatuses transmit their identification information (device ID, location data, sensor information) back to the controller. The controller uses this feedback to identify and select the intended target device among multiple apparatuses, ensuring precise control while maintaining the simplicity of the IR communication system.
3Adaptability or versatility
If smart controller controls multiple electronic apparatuses, then multi-device control is possible, but communication channel must be re-set for each new device
Solution Approach 1:
The patent applies preliminary action by pre-pairing the controller with multiple electronic apparatuses before actual control is needed. During the pairing phase, the controller stores identification information and establishes communication profiles for multiple devices in advance. When control is needed, the controller simply selects from the pre-established connections using device identification, eliminating the need for time-consuming re-pairing operations.
4Device complexity
If IR communication method is used, then one-way communication is sufficient, but it is difficult to identify directed electronic apparatus among multiple apparatuses
Solution Approach 1:
The patent adds another dimension to the communication system by incorporating location information, device ID, and sensor data (such as acceleration sensor orientation) alongside the traditional IR signal transmission. This multi-dimensional information allows the controller to identify the directed electronic apparatus by combining directional information with device identification, solving the ambiguity problem while maintaining IR communication simplicity.

AI summary
A remote controller includes a communicator and a processor configured to control the communicator to transmit an identification information request signal to a plurality of electronic apparatuses paired with the remote controller. Based on a signal that includes identification information being received from two or more of the plurality of electronic apparatuses in response to the identification information request signal, the processor controls the communicator to identify a direction of the remote controller based on a direction from which each of the signals is received. The processor causes communication to be performed via an exclusive communication channel between the remote controller and one of the plurality of electronic apparatuses based on the identified direction.
