Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous vehicle navigation systems struggle to effectively integrate visual information from cameras with other sensory data, such as GPS and sensor data, to make accurate navigational decisions in complex environments.
Innovation Solution
The system uses multiple cameras to provide autonomous vehicle navigation features, analyzing images to identify navigational states and determining navigational rules specific to the vehicle's jurisdiction, thereby informing navigational responses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system integrates multiple sensory data sources (cameras, GPS, sensors) to improve navigational decision accuracy, then the measurement precision and reliability of navigation are improved, but the device complexity and data processing requirements increase
Solution Approach 1:
The system divides the complex navigation task into separate functional modules: image capture devices for visual data, GPS receivers for location data, sensors for environmental data, and a processing unit that integrates these separate data streams. Each module handles specific sensory inputs independently before integration, reducing overall system complexity while maintaining comprehensive data collection
Solution Approach 2:
The processing unit acts as an intermediary that receives and integrates data from multiple sensory sources (cameras, GPS, sensors). This central intermediary component coordinates the fusion of heterogeneous data types, transforming complex multi-source input into unified navigational decisions without requiring direct complex interactions between all sensor components
2Productivity
If the system processes and analyzes visual information from cameras in real-time to identify navigational states and rules, then the responsiveness and productivity of navigation are improved, but the use of energy and computational resources increase
Solution Approach 1:
The system performs preliminary actions by continuously capturing images and pre-processing visual data even before specific navigational decisions are required. The processing unit maintains a ready state with pre-analyzed visual information, enabling faster response to changing conditions without requiring intensive real-time computation for every decision moment
Solution Approach 2:
The system implements periodic action through continuous image capture at defined intervals and periodic analysis of navigational states. Rather than constant high-intensity processing, the system analyzes visual information at periodic intervals sufficient for safe navigation, reducing peak energy consumption while maintaining responsive decision-making capability
3Adaptability or versatility
If the system identifies jurisdiction-specific navigational rules based on location analysis, then the adaptability to different environments is improved, but the difficulty of detecting and measuring location context increases
Solution Approach 1:
The processing unit performs multiple functions: it processes image data for visual navigation, analyzes GPS coordinates for location identification, detects environmental features for context understanding, and determines jurisdiction-specific rules. This multi-functional processing capability allows the single system to handle diverse navigational challenges across different jurisdictions without requiring separate specialized systems
Solution Approach 2:
The system uses feedback mechanisms where detected location context and environmental features are continuously fed back to adjust navigational rule application. The processing unit compares observed environmental characteristics with stored jurisdictional rule sets, refining location identification and rule selection through iterative feedback loops that improve accuracy over time
