Remote Control Device License Activation via Intermediary Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of electronic devices requires multiple remote control devices, leading to lost or outdated remote control signals, and manufacturers' proprietary signal formats cause inconvenience in home use, as existing systems struggle to easily update or manage remote control signals.
Innovation Solution
A remote control device with a communication module that transmits a license activation request to an external server, receives encrypted license activation information, and activates an infrared library database using a license key, allowing for secure and accurate updating of remote control signals, eliminating the need for separate storage and enabling billing based on access counts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If remote control signals are stored in the remote control device, then the device can operate target electronic devices, but the signals cannot be easily updated and new signals cannot be added
Solution Approach 1:
An external server acts as an intermediary to store and manage the infrared library database. The remote control device communicates with this server to download and update remote control signals, eliminating the need for complex local storage and update mechanisms while enabling easy signal updates and expansion.
2Ease of operation
If multiple remote control devices are used for multiple electronic devices, then each device can be controlled, but the risk of losing remote controls increases and management becomes inconvenient
Solution Approach 1:
A single remote control device is designed to control multiple target electronic devices by downloading their respective infrared signals from the external server. This universal approach eliminates the need for multiple dedicated remote controls, reducing the risk of loss and simplifying management while maintaining full control capability.
3Adaptability or versatility
If different manufacturers use different remote control signal formats, then each manufacturer can optimize for their devices, but it causes significant inconvenience in home use
Solution Approach 1:
The external server acts as a universal intermediary that stores infrared signals from multiple manufacturers in a standardized format. The remote control device downloads the appropriate signals from this centralized repository, enabling compatibility with various manufacturers' devices without requiring the user to manually handle different signal formats, thus maintaining convenience.

AI summary
A remote control device for remotely controlling a target device to be controlled is provided. The remote control device includes a communication module configured to transmit a request a license activation to an external server via a gateway along with first remote control device information for identifying the remote control device and first infrared (IR) library information for identifying the IR library DB, receive, from the gateway via the gateway, license activation information encrypted by an encryption algorithm, the encrypted license activation information including second remote control device information, second IR library information, and a license activation key code for the IR library DB, an input module configured to receive a user input for remotely controlling a target electronic device to be controlled, and a controller module configured to decrypt the encrypted license activation information by a decryption algorithm to extract the second remote control device information, the second IR library information and a license activation key code, and activate the IR library DB with the license activation key code, and generate remote control signals corresponding to the user input, utilizing the activated IR library database.
