Navigation System Voice Input and Dynamic Data Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems face challenges such as tedious address entry processes, outdated map data, limited display capabilities, and lack of integration with up-to-date traffic and weather information, leading to driver distraction and inaccurate route planning.
Innovation Solution
A system that uses a GPS module, wireless communication, and an output module to transmit destination and position information to a navigation server, allowing for automatic generation and receipt of navigation information, enabling seamless integration with cellular devices and web services for enhanced navigation, including speech interfaces and real-time traffic/weather updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual address entry is used on touch-screen displays, then navigation destination can be input, but driver distraction increases and operation becomes tedious
Solution Approach 1:
The patent replaces manual mechanical input methods (touch-screen typing, button pressing) with voice recognition technology. The speech interface allows drivers to input addresses verbally while keeping hands on the wheel, converting mechanical input operations into acoustic signal processing that occurs automatically through speech-to-text conversion.
Solution Approach 2:
The system enables self-service by automatically processing speech inputs and converting them into navigation commands without requiring manual intervention. The speech recognition engine autonomously interprets driver commands, identifies destinations, and initiates routing functions, eliminating the need for tedious manual address entry.
2Reliability
If DVD/CD-based map databases are used, then navigation data can be stored, but data becomes outdated and cannot be updated
Solution Approach 1:
The patent transitions from static DVD/CD-based map databases to dynamic web service-based data delivery. Map data, traffic information, and points of interest are delivered through continuously updated web interfaces, allowing the navigation system to access current information without physical media changes or manual updates.
Solution Approach 2:
The system introduces a wireless communication interface and web service intermediary layer between the navigation processor and map data. This intermediary enables automatic data synchronization and updates by fetching current map information, traffic conditions, and points of interest from remote servers, eliminating the obsolescence problem of physical media.
3Ease of operation
If navigation audio is played on car speakers, then directions can be heard, but passengers cannot sleep or listen to uninterrupted media
Solution Approach 1:
The patent segments the audio output function by providing separate audio pathways: one for navigation directions and another for entertainment media. The system can route navigation audio through the car's speaker system while allowing passengers to independently control their own audio devices, dividing the audio output into functional segments that serve different purposes simultaneously.
Solution Approach 2:
The system uses Bluetooth and wireless communication interfaces as intermediaries to connect personal audio devices with the car's audio system. This allows navigation audio to be transmitted wirelessly to personal devices or headphones, creating an intermediary audio pathway that prevents conflict between navigation directions and passenger media consumption.
4Volume of moving object
If cellular phone displays are used for GPS navigation, then portability is improved, but display size is reduced and address entry becomes difficult
Solution Approach 1:
The patent replaces manual mechanical input on small cellular phone keyboards with voice recognition technology. Drivers can input addresses and destinations using speech commands, eliminating the need to physically type on limited mobile device keypads while maintaining the portability benefits of using a cellular phone for navigation.
