Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for controlling multiple consumer electronics devices are complex and cumbersome, requiring users to program multiple remote controls or use proprietary protocols like HDMI-CEC, which are not compatible with all devices and can be difficult to use, especially for legacy devices.
Innovation Solution
A system that uses a remote control device with a wireless transceiver and IR transmitter to communicate with primary devices like TVs and video players, allowing users to control functions wirelessly through a unified interface, with the ability to obtain device data and transmit instructions as Bluetooth low energy signals or IR signals based on device codes, simplifying the control of multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate remote controls are used for different consumer electronics devices, then each device can be controlled with dedicated control codes, but the system complexity and number of devices users must manage increases
Solution Approach 1:
The patent implements a universal remote control device that can control multiple different consumer electronics devices (TVs, audio players, video players, set-top boxes) through a single device. The remote control includes a processor that can store and execute multiple device control codes, allowing one remote to perform the function of multiple dedicated remotes while maintaining compatibility across different device types and brands.
2Reliability
If proprietary control protocols like HDMI-CEC are used, then integration between specific devices is achieved, but compatibility issues arise with legacy devices and cross-brand operation
Solution Approach 1:
The patent employs parameter changes by storing multiple device control codes in the remote control's memory, each code being specific to different device types and manufacturers. The processor can select and execute the appropriate control code based on the target device, allowing the same remote to adapt its control parameters to match different devices' specific requirements, thereby achieving reliable control across diverse device protocols including legacy and cross-brand systems.
3Measurement precision
If manual programming of control codes is required for each device, then device-specific control precision is achieved, but the ease of operation and setup time deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-storing multiple device control codes in the remote control's memory before use. The remote control includes a database of control codes for various device types and manufacturers that are loaded in advance, eliminating the need for users to manually program codes during initial setup. Users can immediately use the remote by simply selecting the target device from available options.

AI summary
A system and method are provided for a device for use with a primary device and a remote control device, the primary device being configured to perform a function, the remote control device including an infrared (IR) transmitter and a wireless transceiver. The IR transmitter is configured to transmit an IR signal based on the primary device control code, and the transceiver is configured to receive a wireless instruction signal. The device comprises a memory and a processor. The processor is configured to execute instructions stored on the memory to cause the device to: obtain primary device data associated with the primary device; generate the wireless instruction signal based on the primary device data; and transmit the wireless instruction signal to cause the remote control device to transmit the IR signal to instruct the primary device to perform the function.
