Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current voice recognition systems in vehicles cannot be updated dynamically, limiting their ability to accommodate new features or commands, such as selecting digital radio channels by name, as they require replacement of storage media.

Innovation Solution

A system and method for remotely updating voice recognition commands using a broadcast signal, which includes a receiver unit, memory unit, processor, and voice recognition engine to filter and update voice recognition data, allowing users to receive spoken commands and match them with stored data for execution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If voice recognition commands are stored on static storage media (DVD), then the system structure is simple and reliable, but the system cannot be updated dynamically and requires replacement of storage media to add new commands

Engineering Contradiction:

Improveability to update voice recognition commandsVSAvoidsystem structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent transforms the static voice recognition system into a dynamic one by enabling continuous updates through broadcast signals. The voice database can now be dynamically updated with new commands and features without requiring physical media replacement, allowing the system to adapt to new functions and commands over time.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces a broadcast signal receiver as an intermediary component that receives voice recognition updates from external sources. This intermediary enables the system to acquire new voice commands without direct user intervention or physical media changes, resolving the contradiction between simplicity and updatability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If new voice commands are added by replacing storage media, then the voice database remains static and simple, but the system loses the ability to be updated on a continual basis

Engineering Contradiction:

Improveability to add new features and commandsVSAvoidtime required to update voice commands

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-configuring the system with a broadcast receiver that automatically captures and processes voice recognition updates as they become available. This eliminates the need for users to manually intervene when new commands are released, as the system proactively updates itself through the broadcast channel.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces the mechanical process of physical media replacement with an electronic broadcast-based update mechanism. Instead of manually swapping DVDs or storage media, the system electronically receives and integrates new voice commands through broadcast signals, dramatically reducing update time and eliminating physical intervention.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If the voice database is static, then the system is simple and reliable, but new digital radio channels cannot be selected by voice command

Engineering Contradiction:

Improveability to select radio channels by voiceVSAvoidcapability to accommodate new radio channels

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent applies universality by designing a voice recognition system that can handle both existing and new radio channels through a single unified update mechanism. The broadcast-based update system provides a universal solution that automatically incorporates new channels, stations, and commands, making the system adaptable to future expansions without requiring separate update processes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A method and a system are provided for dynamically updating voice recognition commands available for controlling a device in a vehicle. A receiver unit of a voice recognition system, located in the vehicle, receives a remotely transmitted broadcast signal. A processor of the voice recognition system extracts voice recognition data from a remaining portion of the broadcast signal and updates voice recognition commands stored in a memory unit, coupled to the processor, with the extracted voice recognition data. A voice input device of the voice recognition system receives a spoken command from a user. A voice recognition engine, coupled to the voice input device and the memory unit, determines whether the spoken command matches one of the stored voice recognition commands in the memory unit. If a match occurs, a recognized voice command is generated. The recognized voice command is sent to an affected device in the vehicle.
