Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional autonomous driving control is used, then the vehicle can operate autonomously, but the cornering control precision is insufficient leading to potential accidents
Solution Approach 1:
The patent implements dynamic control of edge protrusions that can extend and retract based on real-time driving conditions. The edge protrusion mechanism allows the vehicle to dynamically adjust its cornering behavior by protruding edges during turns to increase friction with the road surface, thereby improving cornering control precision and safety during autonomous operation.
2Measurement precision
If the vehicle increases friction consideration for accurate cornering, then cornering precision improves, but the device complexity increases due to additional mechanisms
Solution Approach 1:
The patent divides the vehicle body into modular sections with independent edge protrusion mechanisms at different locations. Each edge protrusion unit can be controlled independently, allowing the system to achieve complex cornering control functions through simple, standardized modular components, thereby managing device complexity while improving cornering precision.
3Adaptability or versatility
If the vehicle uses edges to jump over obstacles, then obstacle avoidance capability improves, but the vehicle stability during normal operation may be affected
Solution Approach 1:
The patent employs preliminary action by detecting obstacles in advance and pre-positioning the edge protrusions before the vehicle reaches the obstacle. The control unit calculates the optimal timing and position for edge protrusion based on obstacle detection data, allowing the vehicle to jump over obstacles efficiently while maintaining stability during normal operation through timely retraction of edges.
