Problem
Existing remote control systems for electronic devices are cumbersome due to small buttons and screens, lacking an efficient and reliable voice command system for user input, which can be enhanced by utilizing an analog audio link for voice command transmission and conversion into executable commands.
Innovation Solution
A voice control system that includes a remote control device with an audio receiver and transmitter, capable of transmitting voice commands via an analog audio link to a broadcast receiver or content display device, which executes these commands using a voice recognition module, and optionally includes a speaker for audio feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional remote control systems use small buttons and screens for user input, then the device structure remains simple, but the ease of operation deteriorates due to cumbersome controls
Solution Approach 1:
The patent replaces the mechanical button-based remote control system with an acoustic field-based voice command system. The remote control device includes a microphone that captures voice commands and transmits them via an analog audio link to the broadcast receiver, which then executes the commands through voice recognition. This substitution eliminates the need for physical buttons and small screens, significantly improving ease of operation while maintaining acceptable system complexity.
2Ease of operation
If a voice recognition module is added to enable voice control, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The broadcast receiver is designed to perform multiple functions: it receives traditional remote control signals, processes voice commands through the integrated voice recognition module, and executes corresponding actions. By making the broadcast receiver multi-functional, the system avoids adding separate dedicated voice control hardware, thereby improving ease of operation while minimizing the increase in device complexity.
3Manufacturing precision
If an analog audio link is used for voice command transmission, then the manufacturing precision requirements are reduced, but the loss of information may increase due to audio signal processing
Solution Approach 1:
The patent introduces an analog audio link as an intermediary transmission medium between the remote control device and the broadcast receiver. This audio link serves as a mediator that carries voice command information, allowing for reduced manufacturing precision requirements in the transmission path while the voice recognition module processes the audio signals to minimize information loss through accurate command identification and execution.
