Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If vehicles are equipped with advanced sensor systems and computational abilities for higher levels of automation, then the level of automation and navigation capability are improved, but the hardware cost, energy consumption, and device complexity increase
Solution Approach 1:
The patent introduces a cloud-based navigation system as an intermediary that provides automated navigation services to vehicles with limited onboard hardware. The cloud system processes complex navigation decisions and sends control commands to the vehicle, enabling higher automation levels without requiring complex onboard sensors and computational resources in each vehicle
Solution Approach 2:
The patent enables vehicles with limited hardware to access and utilize navigation data and processing capabilities from more highly equipped vehicles through the cloud platform. Less equipped vehicles can effectively 'copy' the navigation intelligence of highly equipped vehicles without possessing the same hardware, allowing them to operate at equivalent automation levels
2Extent of automation
If vehicles with limited hardware capabilities use cloud-based navigation systems with higher automation levels, then the navigation capability and automation level are improved, but the data connection requirements and dependency on online services increase
Solution Approach 1:
The patent implements a hybrid approach where vehicles can operate with partial automation using onboard systems when offline, and switch to full automation with cloud-based systems when online. This partial action approach ensures basic operational flexibility is maintained while enabling enhanced automation capabilities when connectivity is available
