Solution Overview
Problem
The proliferation of remote controls for various electronic devices, each requiring specific voice commands and speech recognition units, leads to user inconvenience, increased costs, and complexity due to the need for multiple devices and interactions.
Innovation Solution
A remote control system with a sound transducer, speech recognition unit, memory for storing device content information, and a control signal generator that can manage multiple electronic devices, allowing voice commands to control multiple devices by accessing and updating content information, and generating control signals for device operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate remote control with speech recognition unit is provided for each electronic device, then each device can be controlled with dedicated voice commands, but the number of remote controls increases and user convenience decreases
Solution Approach 1:
The patent implements a universal remote control that can control multiple electronic devices (TV, radio, audio system, DVD player, set top box) through a single device. The speech recognition unit processes voice commands and generates appropriate control signals for different device types, eliminating the need for multiple dedicated remote controls while maintaining reliable device control.
Solution Approach 2:
The patent combines multiple speech recognition units and control functions into a single integrated remote control device. Instead of having separate remote controls for each electronic device, the system merges all control capabilities into one universal remote that can communicate with and control various types of electronic devices through unified voice command processing.
2Adaptability or versatility
If multiple remote controls are used for different electronic devices, then each device has dedicated control capability, but user interaction time and complexity increase
Solution Approach 1:
The universal remote control incorporates speech recognition capability that can identify and route commands to different device types (TV, radio, audio system, DVD player, set top box). Users simply speak their intent without needing to locate or select a specific remote control for each device, significantly reducing the time and effort required to control electronic devices.
Solution Approach 2:
The patent replaces the mechanical approach of physically selecting and pointing different remote controls with a voice-based command system. Instead of manually choosing the correct remote control device, users speak natural language commands that are automatically routed to the appropriate electronic device, eliminating the need to search for or handle multiple remote controls.
3Ease of operation
If speech recognition units are included in each remote control, then voice control is available for each device, but manufacturing costs increase
Solution Approach 1:
The patent consolidates the speech recognition functionality into a single unit within the universal remote control, rather than incorporating separate speech recognition units in multiple remote controls. This merging approach reduces the total number of speech recognition components needed, lowering manufacturing costs while maintaining voice control capability across all controlled devices.
Solution Approach 2:
The universal remote control provides voice control capability for multiple device types through a single speech recognition unit. This multi-functional approach allows one speech recognition system to handle commands for TV, radio, audio system, DVD player, and set top box, reducing the overall cost compared to equipping each device with its own dedicated speech recognition unit.
