Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If fully autonomous systems with dedicated sensors are used, then autonomous navigation capability is improved, but system complexity and cost increase
Solution Approach 1:
The patent applies universality by enabling generic navigation systems with existing perception sensors to perform autonomous navigation functions. The system reuses existing vehicle sensors (cameras, LIDAR, radar) and generic navigation hardware for multiple purposes - both traditional navigation and autonomous collision avoidance, eliminating the need for dedicated autonomous navigation sensors and reducing overall system complexity.
Solution Approach 2:
The system applies self-service by having the generic navigation system's existing perception data and processing capabilities serve the autonomous navigation function. The perception data collected for general navigation purposes is reused for collision probability assessment and path planning, allowing the system to serve itself rather than requiring separate dedicated components.
2Extent of automation
If fully autonomous systems with dedicated sensors are used, then autonomous navigation capability is improved, but cost increases
Solution Approach 1:
The patent reduces cost by making the navigation system universal - existing perception sensors and generic navigation hardware perform both traditional navigation and autonomous navigation functions. This eliminates the need to manufacture and install expensive dedicated autonomous navigation sensor suites, thereby reducing overall system cost while maintaining autonomous capability.
Solution Approach 2:
The system uses copies of existing perception data for autonomous navigation purposes. Rather than creating new dedicated sensors, the system copies and reuses the perception data already being collected by existing sensors for general navigation, significantly reducing hardware costs.
3Reliability
If active safety systems are used, then safety warnings are provided, but fully autonomous operation is not achieved
Solution Approach 1:
The patent merges active safety systems with the generic navigation system into a unified autonomous navigation framework. The collision probability module and path planning algorithms combine safety monitoring functions with navigation decision-making, allowing the system to provide both safety warnings and execute autonomous navigation actions seamlessly.
Solution Approach 2:
The system implements feedback by continuously monitoring collision probability and using this information to adjust navigation decisions in real-time. The objective score array module uses collision probability feedback to dynamically update path planning, enabling the system to achieve autonomous operation while maintaining high safety standards through continuous adaptive control.
