Unified Remote Control Key Mapping for Multiple Device Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems require multiple devices with different control codes, making it inconvenient for users to manage and control various electronic devices, such as TVs, air conditioners, and optical disc players, as separate remote controls are needed for each device.
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 multiple devices without the need for separate remotes.
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 reliably with dedicated control codes, but the number of remote controls increases and user convenience deteriorates
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 control information, enabling one remote to perform functions previously requiring multiple dedicated remotes.
Solution Approach 2:
The remote control apparatus automatically identifies the target device and selects the corresponding control codes without user intervention. The processor receives device identification signals, automatically matches them with stored control information, and transmits the appropriate control codes, eliminating the need for users to manually select device types or remember which remote controls which device.
2Reliability
If multiple separate remote control apparatuses are used for different devices, then each device receives accurate control commands, but the system complexity and number of devices increase
Solution Approach 1:
The patent combines multiple device control functions into a single remote control apparatus. The processor integrates device identification, control code selection, and command transmission capabilities, merging what previously required separate remote controls for TV, air conditioner, optical disc player, and other devices into one unified device.
Solution Approach 2:
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 control information, enabling one remote to perform functions previously requiring multiple dedicated remotes.
3Ease of operation
If a single remote control apparatus controls multiple devices, then user convenience improves and device quantity reduces, but the difficulty of detecting and measuring device identification increases
Solution Approach 1:
The patent introduces transmission devices as intermediaries between the remote control apparatus and electronic devices. These transmission devices receive control signals from the remote control, extract device identification information, and relay commands to the appropriate devices. This intermediary system simplifies the identification process by handling the complex task of matching control codes with specific devices.
