Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional navigation systems provide turn-by-turn navigation instructions, then users receive basic routing guidance, but the instructions do not account for current vehicle situation or road conditions leading to inconvenience
Solution Approach 1:
The navigation system continuously receives feedback from multiple sensors (cameras, radar, LiDAR, GPS) about the current vehicle situation and road conditions, and dynamically adjusts navigation prompts based on this real-time feedback. The system monitors traffic conditions, obstructions, and vehicle state to provide context-aware instructions that adapt to changing circumstances.
Solution Approach 2:
The navigation system integrates multiple sensor types (visual cameras, radar, LiDAR, GPS) and data sources (road sensor data, vehicle sensor data, weather data) into a single unified navigation prompt generation system. This multi-functional approach allows the system to consider various factors simultaneously when generating instructions.
2Reliability
If the navigation system integrates multiple sensors and data sources to provide situational awareness, then navigation prompts become more relevant and useful, but the device complexity increases
Solution Approach 1:
The system segments the complex navigation task into separate modules: sensor data collection, data fusion, route planning, and prompt generation. Each module processes specific types of information independently before integrating results, making the overall system more manageable and maintainable despite the complexity.
Solution Approach 2:
A central processing unit acts as an intermediary that receives data from multiple sensors and data sources, processes and fuses this information, and then generates appropriate navigation prompts. This intermediary layer simplifies the interaction between different system components and data sources.
3Measurement precision
If the system provides detailed enhanced navigation prompts based on real-time sensor data, then users receive more accurate instructions preventing incorrect turns, but the processing time and computational resources increase
Solution Approach 1:
The system performs preliminary actions by pre-processing sensor data and pre-calculating potential navigation prompts before the actual navigation moment arrives. Route planning and sensor data fusion are performed in advance, allowing for faster prompt generation when needed.
Solution Approach 2:
The system applies partial action by selectively processing and considering only the most relevant sensor data and factors for the current navigation situation, rather than processing all available data equally. This prioritization approach maintains precision while reducing processing time.
Data Source
AI summary
A navigation system is disclosed. The system may include a transceiver and a processor. The transceiver may be configured to receive navigation information from a navigation server and sensor inputs from a sensor of a vehicle. The processor may be configured to obtain the navigation information and the sensor inputs from the transceiver, and determine that a predetermined condition, of a plurality of predetermined conditions, may be met based on the sensor inputs. The processor may be further configured to determine a navigation notification based on the predetermined condition and the navigation information. Furthermore, the processor may be configured to output the determined navigation notification.
