Universal Remote Control with Automatic Device Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote control devices are cumbersome and inefficient in managing multiple types of media equipment from different manufacturers, often requiring extensive programming and catalog referencing, which can be time-consuming and ineffective for future equipment additions or modifications.
Innovation Solution
A remote control unit that adapts to various media equipment by retrieving configurations from storage devices via wireless links, using identifiers to access and store settings, allowing it to control multiple devices seamlessly and intuitively through a user-friendly interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a universal remote control supports media equipment from multiple manufacturers, then versatility is improved, but device complexity increases due to the need for extensive programming codes and catalog referencing
Solution Approach 1:
The remote control automatically discovers media equipment in the environment and retrieves configuration information from storage devices without requiring user programming. The system self-configures by obtaining device identifiers and associated control settings from stored configurations, eliminating the need for manual catalog referencing and code entry.
Solution Approach 2:
Configuration information for multiple manufacturers' equipment is pre-stored in storage devices before the remote control needs to use it. The system performs preliminary retrieval of device identifiers and control settings from these storage devices, so that when equipment is added to the home entertainment system, the remote control is already prepared with the necessary configuration data.
2Adaptability or versatility
If a universal remote control uses predefined programming codes from a catalog, then adaptability to existing equipment is improved, but ease of operation deteriorates due to time-consuming catalog referencing and reprogramming
Solution Approach 1:
The remote control automatically discovers media equipment and retrieves its configuration information from storage devices without requiring the user to manually reference catalogs or enter programming codes. The system performs self-configuration by obtaining device identifiers and associated settings automatically.
Solution Approach 2:
The manual mechanical process of catalog referencing and code entry is replaced with an automated electronic system. The remote control uses wireless communication to automatically retrieve configuration data from storage devices, substituting the manual information-seeking process with automated data retrieval.
3Ease of operation
If a universal remote control is designed for a single manufacturer's equipment, then ease of operation is improved, but adaptability deteriorates when equipment from different manufacturers is added
Solution Approach 1:
The remote control is designed to support media equipment from multiple manufacturers by retrieving configuration information from storage devices. The system can adapt to different manufacturers' equipment types (televisions, set top boxes, DVD players, audio systems, etc.) while maintaining a consistent user interface and operation method.
Solution Approach 2:
Configuration information for equipment from multiple manufacturers is pre-stored in storage devices. When new equipment is added, the remote control automatically retrieves the necessary configuration data from these pre-prepared storage devices, enabling seamless expansion without requiring the user to learn new control methods.
4Adaptability or versatility
If a universal remote control requires learning from dedicated remote controls, then adaptability is improved, but loss of time increases due to repeated training processes
Solution Approach 1:
Configuration information is pre-stored in storage devices before the remote control needs to use it. The system performs preliminary retrieval of device identifiers and control settings, so that when equipment is added or batteries are replaced, the remote control is already configured and ready to use without requiring re-learning or re-programming.
Solution Approach 2:
The remote control automatically discovers media equipment and retrieves its configuration information from storage devices without requiring the user to manually program it. The system self-configures by obtaining device identifiers and associated settings automatically, eliminating the time-consuming learning process.
Data Source
AI summary
A portable control unit that interacts with a variety of types of media equipment. The control unit searches for media equipment (including media players) located within an area and retrieves user interaction information corresponding to discovered media players. The control unit can be instructed to control any of the discovered media players. The control unit uses the retrieved user interaction information to adapt. The control unit may periodically, or when relocated, look for new media players in its neighborhood. The control unit interacts with multiple multimedia sources that supply video and/or audio to the media players. The control unit may have a screen on which it displays a video in addition to controlling selection and presentation of a video and/or an audio in any one of the discovered media players. The control unit maintains an updateable media guide that provides a list of multimedia elements available for viewing and/or listening.
