Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated driving vehicles navigate diverse road types and conditions without virtual boundaries, then vehicles have greater freedom of movement, but safety issues and navigation inefficiencies occur
Solution Approach 1:
The patent creates virtual copies of physical road boundaries and stop lines as imaginary lines in the map information. These imaginary lines replicate the function of physical road markings without requiring physical infrastructure, enabling automated vehicles to navigate safely through digital representations of road rules and boundaries.
Solution Approach 2:
The patent transitions from physical road boundaries to digital/virtual imaginary lines in the information space. By managing boundaries as data rather than physical objects, the system achieves flexible, dynamic boundary management that adapts to changing road conditions without physical modifications.
2Adaptability or versatility
If the system dynamically adjusts imaginary lines and stop lines to accommodate obstacles and varying conditions, then navigation adaptability improves, but computational complexity and processing requirements increase
Solution Approach 1:
The patent implements dynamic imaginary lines that automatically adjust their positions and configurations in response to changing road conditions, obstacles, and traffic situations. The imaginary stop lines are generated and repositioned dynamically based on obstacle detection and road layout changes, enabling real-time adaptation without manual intervention.
Solution Approach 2:
The system pre-generates imaginary lines and imaginary stop lines based on map information before vehicles encounter obstacles or complex situations. By having these virtual boundaries prepared in advance, the system reduces real-time computational burden while maintaining high adaptability when vehicles need to respond to changing conditions.
3Manufacturing precision
If imaginary stop lines are generated to intersect imaginary lines and surround parking areas, then vehicle control precision improves, but the complexity of line management and coordination increases
Solution Approach 1:
The patent segments the road environment into distinct virtual zones defined by imaginary lines and imaginary stop lines. By dividing the navigation space into manageable segments with clear boundaries and stop points, the system achieves precise vehicle control at critical locations while maintaining organized, modular line management that reduces overall system complexity.
