Remote Control Apparatus Key Matching for Multi-Device Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems require multiple devices, each with its own remote control, leading to user inconvenience due to the need for separate controls and additional applications for different electronic devices.
Innovation Solution
A remote control apparatus with a key input unit, receiver, processor, and transmitter that identifies multiple devices via device identification signals and matches keys to control commands, allowing for unified remote control of various devices without a display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate remote control apparatuses are used for each electronic device, then each device can be controlled with dedicated control codes, but user convenience deteriorates due to needing multiple remotes
Solution Approach 1:
The remote control apparatus is designed to control multiple types of electronic devices (TV, air-conditioner, optical disc player, etc.) with a single device. The processor automatically identifies the target device by receiving device identification signals and selects appropriate control codes from stored code groups, enabling one remote to replace multiple device-specific remotes while maintaining reliable control for each device type
2Ease of operation
If a remote control apparatus with display is used to show control options, then user interface is improved, but device complexity and power consumption increase
Solution Approach 1:
The display component is extracted/removed from the remote control apparatus. Instead of showing control options on a display, the system uses automatic device identification through received identification signals and internally processes control code selection, transmitting the appropriate control signals without requiring visual feedback or additional display hardware

AI summary
The present invention relates to a remote control apparatus which can remotely control multiple devices. A remote control apparatus according to an embodiment of the present invention comprises: a key input unit having multiple keys; a reception unit for receiving at least one device identification signal from at least one device or a transmission device corresponding to the device; a processor for detecting an identification signal for a device, which can be remotely controlled, from the at least one received device identification signal, extracting information on a control command for the remote control of the device, on the basis of the detected identification signal, and matching at least one of the multiple keys to the control command for the remote control of the device, on the basis of the extracted information on the control command; and a transmission unit for transmitting a signal corresponding to the control command when the key matched to the control command is selected. Accordingly, the present invention can remotely control multiple devices.
