Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing universal remote controllers for broadcast receivers require complex processes for registering new devices, including the use of a personal computer to find and verify infrared code sets, which is inconvenient and limits support for special functions specific to certain broadcast receivers.
Innovation Solution
A control device with a user interface unit for receiving broadcast receiver information, a searching unit to find corresponding infrared code sets, and a communication interface to register and transmit control signals, allowing easy setup and control of new broadcast receivers in a home network, including bidirectional wireless communication for menu information and IR code management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional universal remote controller is used to register a new broadcast receiver, then the device can control various broadcast receivers, but the registration process becomes complicated requiring a personal computer and code verification
Solution Approach 1:
The control device automatically detects and registers broadcast receivers without requiring external personal computer assistance. The device performs self-service by autonomously searching for IR codes, verifying control functionality, and storing device information in its own memory, eliminating the need for users to use a PC for registration.
Solution Approach 2:
The control device acts as an intermediary between the user and the broadcast receiver network. It manages the complex tasks of code searching, device identification, and control verification internally, presenting a simplified registration process to the user while handling the technical complexity through its built-in searching unit and managing unit.
2Measurement precision
If a personal computer is used to register a new broadcast receiver on the universal remote controller, then the code set can be found and verified, but the process becomes inconvenient and requires additional equipment
Solution Approach 1:
The patent extracts the code searching and verification functionality from the external personal computer environment and integrates it directly into the control device. The searching unit and managing unit are built into the remote controller itself, allowing code sets to be found and verified internally without requiring external PC software or equipment.
Solution Approach 2:
The control device performs self-service by autonomously conducting IR code searches, testing control functionality, and verifying device registration without external assistance. The device uses its own communication interface and processing units to complete the entire registration process independently.
3Adaptability or versatility
If the universal remote controller supports a general code set for broadcast receivers, then it can control most devices, but it cannot support special functions specific to certain broadcast receiver models
Solution Approach 1:
The patent segments the code set management into organized categories by manufacturer and device type. The managing unit stores and manages multiple IR code sets in a structured manner, allowing the control device to select and apply appropriate code sets based on the specific broadcast receiver being controlled, thereby supporting special functions while maintaining organized management.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case

Implementation Method 1
a first communication interface unit which, if a control signal of the registered broadcast receiver is received, transmits an IR code corresponding to the control signal from the IR code set corresponding to the registered broadcast receiver to the registered broadcasting receiver
Data Source
AI summary
A control device is provided. The control device includes a user interface unit in which information of a broadcast receiver controlled through unidirectional wireless communication is entered, a searching unit which searches an infrared (IR) code set corresponding the broadcast receiver based on the entered information, a managing unit which registers the broadcast receiver as a controllable broadcast receiver within a home network based on the searched IR code set, and a first communication interface unit which, if a control signal for the registered broadcast receiver is received, transmits an IR code corresponding to the control signal from the IR code set corresponding to the registered broadcast receiver to the registered broadcasting receiver.
