Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If infrared communication is used for remote control, then the remote controller can control electronic devices, but the control is limited to a specific space and obstacles block the signal
Solution Approach 1:
The patent combines infrared and radio frequency communication modules in a single remote controller. The infrared module maintains reliable line-of-sight control, while the RF module provides obstacle-free wireless control, allowing the remote to adapt to different spatial environments and control scenarios.
Solution Approach 2:
The remote controller is designed with dual communication capabilities (infrared and RF) to perform multiple functions: it can control devices requiring line-of-sight communication and devices that need wireless penetration through obstacles, making it universally applicable to various electronic devices and control situations.
2Adaptability or versatility
If radio frequency communication is used for remote control, then the remote controller can control electronic devices without spatial limitations, but a complicated pairing setting process is required
Solution Approach 1:
The television serves as an intermediary device that facilitates automatic pairing between the remote controller and audio devices. When the remote sends a control signal, the television receives it and automatically establishes the RF connection with the audio device, eliminating the need for manual pairing operations by users.
Solution Approach 2:
The system implements automatic pairing functionality where the television and audio devices automatically establish connections and exchange pairing information without requiring user intervention. The pairing process is performed autonomously by the devices themselves, simplifying the user experience.
3Adaptability or versatility
If radio frequency communication is used for remote control, then the remote controller can control electronic devices without spatial limitations, but electronic devices incapable of transmitting and receiving RF signals cannot be controlled
Solution Approach 1:
The remote controller incorporates both infrared and RF communication modules to achieve universal compatibility. The infrared module controls devices that require line-of-sight communication, while the RF module controls wireless devices, allowing the remote to work with a wide variety of electronic devices regardless of their communication capabilities.
Solution Approach 2:
The remote controller dynamically changes its communication parameter (infrared or RF) based on the target device type. The system detects which communication method the target device supports and automatically switches to the appropriate mode, ensuring reliable control across different device types.

AI summary
A remote controller is provided. The remote controller includes an input interface; a communicator; a storage; and a processor configured to: transmit, to the display apparatus via the communicator, a signal indicating control instructions based on a user input received through the input interface, receive, from the display apparatus via the communicator, information related to a first control code for controlling a first source device of the at least one source device based on the control instructions, identify the first control code from a first control code set stored in the storage based on the information related to the first control code, and control the communicator to transmit a first control signal indicating the first control code to the first source device.
