Remote Control Code Database Extraction for Memory Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity and number of controllable electronic devices require remote controls to have greater storage capacity for functionality and databases, leading to higher costs and management challenges, necessitating a solution to reduce memory requirements in remote controls while maintaining user experience.
Innovation Solution
Implementing a system where the remote control device communicates with a main controllable electronic device to access a database of codes for setting circuitry to control auxiliary devices, reducing storage needs in the remote control and facilitating database management by storing codes in a separate device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the remote control stores a database of codes locally, then it can control multiple devices independently, but the memory requirements and cost increase
Solution Approach 1:
The database of codes is extracted from the remote control device and stored in a separate external device. The remote control retains only the functionality to communicate with and retrieve codes from the external database, thereby reducing its memory requirements while maintaining the ability to control multiple devices.
Solution Approach 2:
The external device storing the database serves multiple purposes: it acts as a code repository for the remote control, can update the remote control's code database, and can manage multiple device profiles. This universal approach allows one external device to support multiple remote controls and multiple target devices.
2Ease of operation
If the remote control includes all setup functionality and electronics, then it operates independently, but the cost and complexity increase
Solution Approach 1:
The setup functionality and database management electronics are extracted from the remote control and placed in a separate external device. The remote control retains only the essential communication and code retrieval functions, reducing its complexity while maintaining operational capability through the external device's support.
Solution Approach 2:
The external device acts as an intermediary between the user and the remote control, providing database management, code updates, and setup functionality. This mediator approach allows the remote control to remain simple while still accessing comprehensive device control capabilities through the external device's mediation.
3Speed
If the database is stored in the remote control, then code access is fast, but database management and updates are difficult
Solution Approach 1:
The database is extracted from the remote control and stored in an external device that is optimized for data management. This external device can easily update, modify, and manage the database without requiring changes to the remote control hardware or complex programming, thereby simplifying database management while maintaining fast access through direct communication.
Solution Approach 2:
The external device performs preliminary actions by pre-processing and organizing the database before the remote control needs to access it. This includes pre-validating codes, organizing device profiles, and preparing update packages, which simplifies the remote control's access operations and makes overall database management more efficient.

AI summary
A remote control device may include: first circuitry to control a function of a first electronic device; second circuitry to be set to control a function of a second electronic device; and a setup controller to set the second circuitry to control a function of a target electronic device based on a code received from a separate device. An electronic device to be controlled by a remote control device may include: an input device to receive a signal from the remote control device; an output device to send a signal to the remote control device; and a processor coupled to the input and output devices, and configured to access a database of codes and to selectively provide codes from the database to the remote control device, the codes configured to set circuitry of the remote control device to control a function of the electronic device and/or an auxiliary electronic device.
